Welcome to the healthy luxury of a salt water swimming pool
We at Eco-MATIC are dedicated to providing you with the most luxurious, healthy, ‘natural’ pool water you have ever
experienced, as well as the most reliable product and the best after-sales service you could hope for.
Reading this Guide will help ensure that your Eco-MATIC system functions correctly and efficiently, help avoid the expense
of unnecessary service calls and make you aware of certain maintenance procedures which, if left undone, may void warranties
offered by the manufacturer. Please refer to the Trouble-Shooting section of this Guide before calling for in-field service.
Overview of the Eco-MATIC Salt Water Pool System
When salt (pure, natural evaporated ocean salt) is dissolved in pool water and then subjected to simple electrolysis
(by way of the in-line Eco-MATIC ‘Cell’), the chloride portion of the salt (sodium chloride) is transformed into an effective
sanitizer,* which has the ability to oxidize (kill) bacteria, virus, algae and other such radicals which would otherwise flourish in
the water. This process is reversible, so does not consume the salt, which is simply used over and over again.
Sized to suit your particular pool or spa, your Eco-MATIC system will provide all of the sanitizer necessary to maintain your
pool/spa water in perfectly healthy condition, in an environmentally-perfect manner, by using and recycling a natural
product – salt. Your Eco-MATIC will do exactly the same thing as ‘pool chlorine’ would do, but without the need to add
(or swim in) potentially harmful, toxic man-made sanitizing chemicals.
*(HOCl the same effective sanitizer as would result if ‘pool chlorine’ was added to the water – but without the potentially
dangerous chlorine compounds and the obnoxious ‘chemical’ effects commonly associated with manual chlorination – and
without the need to handle chemicals.)
Your Eco-MATIC Equipment
When correctly installed, your Eco-MATIC will operate ONLY WHEN THE FILTER PUMP IS OPERATING and water is flowing
through the ‘Cell’. Your Eco-MATIC must not be able to operate while the filter pump is OFF. If your Eco-MATIC continues to
operate after the filter pump is switched OFF (as indicated by bubbling and cloudiness at the ‘Cell’), contact your Eco-MATIC
Dealer or the person who installed your Eco-MATIC immediately and ensure that the fault is rectified.

4 714.384.0382
Installation Check List
Your Eco-MATIC installation is complete when the following have been completed:
• ‘Cell Housing’ installed into plumbing.
• ‘Cell Housing’ should be mounted ‘horizontally’.
• ‘Cell Housing’ should be located downstream from filter, heater and all other accessories, and before any spa valve.
• Water flow direction should be away from the head of the ‘Cell’ in poor flow rate conditions.
• ‘Cell’ properly in place in ‘Cell Housing’.
• ‘Power Pack’ mounted in place.
• ‘Power Pack’ connected to main power (be sure your 220/240V or 110V Eco-MATIC is connected to correct voltage).
• You must check and confirm that your Eco-MATIC ‘Power Pack’ switches ON and OFF coincidentally with the filter pump.
• ‘Power Pack’ connected to ‘Cell’ (including the Gas-Sensor connection).
• Sufficient salt dissolved into pool water.
Understanding the Eco-MATIC System
Your Eco-MATIC uses the dissolved salt in the water to produce the sanitizer necessary to maintain your pool/spa water in a
safe and healthy condition.
The amount of sanitizer produced by the Eco-MATIC and the quantity of salt (the salinity) in the water are related, but must
be maintained and controlled as two separate factors:
Sanitizer:
The amount of sanitizer required for your pool varies from time to time and depends upon a number of variables, including
the number of swimmers in the pool, water temperature, etc.
To determine whether your Eco-MATIC is producing sufficient sanitizer for YOUR pool/spa, the sanitizer level in the pool/spa
must be measured using a normal ‘chlorine’ Test Kit. The sanitizer level in the water can then be adjusted up or down as desired,
by adjusting the quantity of sanitizer being produced by the Eco-MATIC (refer to System Control).
Low sanitizer levels should not be confused with a low salt level, and adding more salt will not necessarily increase the
sanitizer level. The salt level should be controlled and maintained separately – see below.
Salt Level (Salinity):
Your Eco-MATIC will indicate (Control Panel) whether the salt level in the water has fallen below the desired minimum
operating level. The system will continue to produce sanitizer in low salt conditions (at a decreased rate, and only until the
automatic Cut-Out applies – if your product includes this feature) but low salt conditions cause increased wear on the ‘Cell’
and will shorten the life of the ‘Cell’. When your Eco-MATIC indicates a Low Salt condition, add salt to the water to correct the
situation. Measure and control sanitizer levels separately, as described above.
Note: Never add salt in order to increase sanitizer level. Only add salt, as necessary, to maintain minimum salt level.
The Amount of Sanitizer Produced by Eco-MATIC Depends Upon:
a) The daily operating time of the equipment (pump/filter and Eco-MATIC). Suggested operating times vary depending on
weather conditions, pool usage, etc (as little as 4 hrs in winter, to 8-12 hrs in summer or more in certain adverse conditions).
b) The System Control setting (high or low)
c) The condition of the Eco-MATIC ‘Cell’ (clean or dirty)
The rate of sanitizer production will decrease as the ‘Cell’ (ESR Models) accumulates scale (calcium, etc), or if the salt level
in the water decreases and, in time, as the ‘Cell’ nears the end of its life.
Note: Your Test Kit is your ONLY INDICATOR of whether your Eco-MATIC is producing sufficient, too little, or too much
sanitizer for your pool.
If your Eco-MATIC is producing TOO MUCH SANITIZER, turn the System Control DOWN, or reduce the daily operating time
(being sure to maintain at least the minimum recommended daily filtering time).
If your Eco-MATIC is producing TOO LITTLE SANITIZER, turn the System Control UP, or increase the daily operating time of
the equipment (and refer to trouble-shooting, including stabilizer/conditioner level).

Controls and Display Panel
The rate at which your Eco-MATIC produces (sanitizer for your pool) varies (see below) and is indicated on the DIGITAL
DISPLAY (Eg: 90 – 100 or in winter mode 75 – 85).
There are two lights on the Control Panel – LED 1 and LED 2 – which will indicate whether the system is working as intended
or whether there may be faulty or damaging operating conditions (such as low salt levels). If these warnings are ignored, the
Unit will either Cut-Out (only if your Eco-MATIC includes the Cut-Out feature) OR otherwise, continued operation will result in
damage to the ‘Cell’.
Start Up
1. Turn the POWER ON (first time only). Power setting “1”. Switch filter pump ON (Eco-MATIC also gets power). Eco-MATIC
power switch can then be left ON and filter power control will also control the Eco-MATIC.
2. The unit will enter a START-UP PHASE (which will repeat itself at the start of each filtration period). The STANDBY light will
be ON, but there will be no ‘Cell’ output (sanitizer production).
3. After the Start-Up delay, the DISPLAY should indicate around 90 – 105 (unless set in the Winter Mode). With the correct
amount of salt added and dissolved, both LED 1 and LED 2 will be GREEN. If LED 2 is RED, there is insufficient salt in the pool.
See the table on the page 6 for other installation related problems.

Indicators - What They Mean
Output readings on the DIGITAL DISPLAY can fall due to any (or combination of) the following: cooler water temperatures,
warming of power pack (in heated equipment rooms for example), lower than normal power voltage, lower salt levels, scaling
occurring on ‘Cell’.
Provided LED 1 and LED 2 are both GREEN ( and the ‘Cell’ is not scaling excessively), your Eco-MATIC is performing
(producing) satisfactorily.

Red LED(s): Scaled ‘Cell’ or Low Salt Level.
The ESC Models operate similarly to the ESR Models, as shown above. The ESC Models have the following additional features:
a) Polarity Indicator: The + or - symbol appears before the Digital Output Display, to indicate the polarity in which the
system is operating (i.e. positive or negative direction of ‘Cell’ current). The symbol will alternate according to pre-set
factory settings and does not effect the normal operation of the unit.
b) System Control: When the System Control is being adjusted, the ESC units will indicate (flashing) the percentage of
time that the ‘Cell’ will operate during the filtration cycle (for a few seconds, then display reverts to ‘Cell’ Output display).
c) ‘Cell’ Cleaning: The ESC units use a patented Electronic Auto-Cleaning system for the ‘Cell’. ‘Cells’ may eventually scale in
extreme hard water conditions and will require manual cleaning if this occurs.
d) The second Low Salinity warning phase (Red + Red LED’s) is very short. Therefore on first warning phase (Red + Green
LED’s) prompt action is recommended to avoid Cut-Out.
Operation of the ESC Models

Stand-by Indicator
The Stand-By indicator will be ON when the Unit is preparing to produce sanitizer. This will be either during the system’s
initial Start-Up or when the ‘Cell’ is in an OFF cycle during the filtration cycle (refer System Control). Stand-By indicator can
also be ON after System Protection Cut-Out has activated. (ie: when unit has shut down).
If there is a problem with water flow or gas is detected in the ‘Cell Housing’ the Flow indicator will be ON. When this occurs
the pump or pipes should be inspected for damage and the Gas Sensor on the ‘Cell’ checked for correct connection (and scale
build-up on bolt head).
Flow Indicator
The System Control allows you to control the amount of sanitizer to be produced during any filtration cycle (filter operating
time).
The setting on the System Control determines the amount of time for which the Eco-MATIC will operate during the filtration
cycle. The System Control dial is graduated approximately as follows: 0% (MIN), 20%, 40%, 60%, 80%, (MAX) 100%.
The System Control will not vary the rate at which the ‘Cell’ will produce sanitizer (as indicated on the DISPLAY), just the
‘time’ for which the Eco-MATIC will produce sanitizer. For example:
Daily Filter System Control Hours of
Operating Time Setting Sanitizer Production
8 hours 60% 4.8 hours (60% of 8 hours)
12 hours 20% 2.4 hours (20% of 12 hours)
8 hours 100% 8 hours (100% of 8 hours)
6 hours 50% (halfway) 3 hours (50% of 6 hours)
When the System Control is set to MIN, the ‘Cell’ will be OFF for the duration of the
filtration cycle.
When the System Control is set to MAX, the ‘Cell’ will be ON for the full duration of
the filtration cycle.
The System Control is graduated in steps of 20% from MIN (OFF) to MAX (ON).
(Refer diagram to the right)
Note: If the Eco-MATIC is controlled by ORP chemical automation, turn the control know to MAX.
During any filtration cycle, when the System Control is set between MIN and MAX, the ‘Cell’ will be turned ON and OFF a
number of times each hour. Using the previous example (of 60%), the ‘Cell’ will operate for about 36 minutes each hour. This
36 minute operating time will be made up of a number of smaller operating periods. As an example, the ‘Cell’ may turn ON 12
times (for a period of 3 minutes each time) to make up the 36 minutes. This enables the electronic circuitry to re-adjust to any
changes in the pool water condition. For example, dilution from winter rains, the addition of salt, etc.
If the ‘Cell’ is OFF and you wish to check its operation, simply turn the System Control to MAX and the ’Cell’ will turn ON.
Once checked, adjust the System Control back to the desired position and after a few minutes the ‘Cell’ will turn OFF again.
To turn the ‘Cell’ OFF, simply turn the System Control to MIN. This will be convenient when backwashing filter.

Low Salinity Indicator and Cut-Out
Your Eco-MATIC is fitted with a number of protective features including the Low Salinity Indicator, and on some models, a
Cut-Out feature.
As the salt level in the pool decreases, the wear on the ‘Cell’ increases. Although salt is not consumed in the Eco-MATIC
process, it is lost through splashing, back-washing and on bathers as they leave the pool. The salt level is also reduced by rain,
which causes dilution. Salt is not lost to evaporation. As the salt level in the pool falls toward the minimum, LED 2 will turn RED.
At this point the salt level should be increased by adding approximately 50 lbs of salt per 5000 gallons of water. If no action is
taken and the salt level continues to fall, the Low Salinity Cut-Out will activate and LED 1 will also turn RED. It is advisable to
satisfy yourself that the salt level is in fact low, prior to adding salt, as LEDs 1 and 2 can activate for reasons other than ‘low salt’.
Salt Tests Strips can be used to confirm the salt level in the water. If you have no means of measuring salt level, add the suggested
amount of salt and dissolve it my vacuuming or sweeping onto floor drain. If the LED indicators do not change, the salt level in
the water MUST be measured prior to adding additional salt (take a sample to your local pool store or send a sample to your
Eco-MATIC Dealer for testing). This will prevent adding too much salt when ‘low salt’ may not be the problem.
When the Cut-Out feature activates, the Eco-MATIC will no longer produce sanitizer, but will switch itself ON a number of
times each hour and assess whether the problem(s) (low salt for example) have been corrected. If the problem still exists, the
unit will switch OFF once again.
Other factors which can activate the Cut-Out feature:
1. Heavy Rain - can cause very dilute pool water to pass over the ‘Cell’ due to surface skimming. The Unit will turn back ON
after the rain has been mixed into the water unless the salt level has been reduced by dilution/overflow.
2. Scaled ‘Cell’ - a scaled ‘Cell’ will not draw as much electrical current as a clean ‘Cell’ when first started. This will cause
the Cut-Out to operate. This is very beneficial as a scaled ‘Cell’ can cause an overload if it is operated for a few hours. Heavy
scale build-up also increases the wear on the ‘Cell’.
3. Cold Water - cold pool water reduces the ability of a ‘Cell’ to carry electrical current. (Refer Winter Mode below).
4. Failing ‘Cell’ - as ‘Cell’ ages there will come a time when the electrical current draw will drop. This can be compensated
for with the addition of extra salt. A ‘Cell’ is considered failed when it draws less than 80% of maximum current. To keep a failed
‘Cell’ in operation, Winter Mode can be used along with extra salt. There will come a time when the ‘Cell’ will not respond to
either extra salt or Winter Mode. It will then need to be replaced.
When the ‘Cell’ draws electrical current from the Power Supply, the amount of current drawn is dependent upon a number of
factors. Two of these factors are Salinity and Water Temperature.
The Low Salinity Indicator and/or Cut-Out on your Eco-MATIC are designed to operate at swimming season water
temperatures. When the pool begins to cool in the off season the temperature drop causes the ‘Cell’ to behave differently – it will
draw less electrical current. This can cause the Low Salinity Indicator and/or Cut-Out to assume that the salinity has fallen
even if the salinity has remained relatively constant.
When the temperature of the pool water drops (typically when it is too cold to swim), the Winter Mode Switch should be
placed in the ON position. The Winter Mode Indicator will then be ON.
Winter Mode setting has two effects:
1. It alters the setting of the Low Salinity Indicator and/or Cut-Out.
2. It reduces the Cell Output by approximately 15%.
The Unit will now respond to a cold pool environment. Winter Mode should not be used in the swimming season as it
reduces the Cell Output, leading to less sanitizer, and it alters the setting of the Low Salinity Indicator and/or Cut-Out, which
could lead to premature ‘Cell’ failure.

Gas Sensor
The smaller of the three leads which connect to the ‘Cell’ head is the Gas Sensor. Whenever the head of the Gas Sensor
bolt loses contact with the water (due to gas or air pocket in ‘Cell’, or scale build-up on sensor bolt head), your Eco-MATIC
will Cut-Out.
Your Eco-MATIC must operate daily in order to produce sufficient sanitizer for your pool. In average summer weather
conditions, with average family use of a pool, the daily operating time should be the daily operating time should be as
recommended by your filter manufacturer or pool maintenance person - in average summer climates usually 6 - 8 hours per day,
but in hot climates and if pool is heavily used as much as 12 or 14 (or more) hours per day. Your TEST KIT is the ONLY means
of determining whether your Eco-MATIC is producing sufficient sanitizer for your pool.
It is suggested that the daily operating time be broken down into 2 sessions – one in the early morning and one in the late
afternoon, early evening. This will optimize the effectiveness of the sanitizer which the Eco-MATIC produces.
Always operate the pool filter and Eco-MATIC while the pool is being used.
Day to Day Operation of Eco-MATIC
Periodically, especially in very hot climates and if the pool is heavily used, it may be necessary to boost the amount of sanitizer
in the pool in order to maintain absolute sanitation of the water. This can be achieved simply by operating the Eco-MATIC for an
extended period (say 24 hours) with the System Control set at MAXIMUM.
Shocking the Pool
The ‘Power Pack’
The POWER PACK should require very little (if any) maintenance – except maybe for occasional replacement of blown fuses.
However, damage to certain components may result from improper maintenance of the ‘Cell’ (see below). Always ensure that the
POWER PACK is located in a well ventilated area free of corrosive fumes from any acid or chemical containers in the vicinity.
Important Note: The two most important maintenance requirements for your Eco-MATIC are:
1. Cleaning the ‘Cell’ and
2. Maintaining sufficient salt level in the pool.
The ‘Cell’
Maintenance of the ‘Cell’ is quite simple, but very important. Eco-MATIC ‘Cells’ are comprised of expensive materials and even
with proper care and maintenance the delicate coating on the ‘Cell’ anode will eventually wear away and the ‘Cell’ will ‘die’ and
will no longer be able to produce sufficient sanitizer for the pool. Proper care (and cleaning) will ensure the maximum life for
the ‘Cell’. Operating your ‘Cell’ on lower-than-recommended salt levels will shorten ‘Cell’ life and void ‘Cell’ warranties.
Cell Life
The life expectancy of Eco-MATIC ‘Cells’ may vary considerably from one installation to the next, due to variations in daily
operating time, water quality and composition, system and ‘Cell’ maintenance.
The ESC48 and ESC24 models use the same size ‘Cell’. However, due to the increased ‘Cell’ output of the ESC48, its ‘Cell’ will
have a shorter life than that of the ESC24.
Please ensure that when it is time to replace your ‘Cell’, you use only Eco-MATIC replacement ‘Cells. The use of imitations (or
copies) of the Eco-MATIC ‘Cell’ may harm the internal components of your Eco-MATIC Power Pack and will void warranties.
Maintenance of Your Eco-MATIC

10 714.384.0382
Maintenance of Your Eco-MATIC (Continued)
Cleaning The ‘Cell’
Mineral salts, calcium, etc. (scale) will accumulate onto the ‘Cell’ and will effect the efficiency of the ‘Cell’ in its production
of sanitizer. If allowed to build up unchecked, this scale can damage the ‘Cell’. It is therefore essential that the ‘Cell’ be cleaned
whenever necessary, as indicated by visual inspection, a drop in Output and/or RED LED(s).
The rate at which the scale accumulates on the ‘Cell’ varies from pool to pool and is influenced mostly by the Total Hardness,
Total Alkalinity and the ratio of these two important components of water balance. Rapid scaling on the ‘Cell’ indicates the need
to adjust either the Total Hardness and/or the Total Alkalinity of the pool water (refer to Maintenance of the Water).
Removing The ‘Cell’ For Cleaning
There should be no need to disconnect the ‘Cell’ from its leads for normal ‘Cell’
cleaning. However, it may be necessary at some time to disconnect the cell (‘Cell’
replacement, warranty or service reasons).
The ‘Cell’ leads connect to the ‘Cell’ Head with push-in bayonet type connectors.
Simply twist and pull each connector to disconnect. The Gas Sensor lead is a
push-on connection – simply pull to disconnect. Do not attempt to remove by pulling
on the wires. Be sure to color-match the connectors when reconnecting.
If a ‘Cell’ Head Cover (optional) is fitted to your ‘Cell’ it can be removed by
undoing the screws which hold it in place.
How To Clean The ‘Cell’
• Turn OFF filter pump before attempting to clean the ‘Cell’.
• Remove the ‘Cell’ from the ‘Cell Housing’ by unscrewing the ‘Cell’ Head (Note: left-hand thread. Turn in direction of ‘OPEN’
arrow on ‘Cell’ Housing). No need to disconnect ‘Cell’ leads.
• Immerse the ‘Cell’ into the weak acid solution (see below) for as short a time as necessary for the scale to be dissolved off
the ‘Cell’
• If necessary, remove the ‘Cell’ from the weak acid solution, brush with a soft brush (never use a metal brush) to help remove
stubborn scale, then re-immerse into the weak acid solution. Repeat until ‘Cell’ is completely clean of scale.
• Remember to also clean scale off head of Gas Sensor bolt (on inside of ‘Cell’ head).
• Either rinse the acid solution off the ‘Cell’ using fresh water, or immediately replace the ‘Cell’ into the ‘Cell Housing and start
the filter (so the pool water rinses the ‘Cell’).
NEVER tap or knock the ‘Cell’ against hard objects to help remove scale. ‘Cell’ will break.
NEVER clean the ‘Cell’ in undiluted acid solution (always dilute in water – see below).
NEVER leave the ‘Cell’ immersed for long periods in the acid solution (remove and rinse as soon as scale is removed).
When re-inserting the ‘Cell’ into the ‘Cell Housing’, ensure that the O-ring is in place (seated in the groove in the ‘Cell’ Head).
If it is difficult to have the O-ring stay in its groove, apply lube gel to O-ring, then re-fit into groove. Do not over-tighten the ‘Cell’
(hand tight is OK).
Weak Acid Solution
Add 3 parts water to the ‘Cell’ cleaning container, then add 1 part acid (pool acid, muriatic acid) to the water, to a total depth
which allows all of the ‘Cell’ mesh to be immersed.
Warning: NEVER add water-to-acid. ALWAYS add acid-to-water
The weak acid solution can be stored in a safe place (some place where the kids can’t get at it) and
re-used for some time before becoming ineffective (saves having to make the solution each time). Avoid
getting the weak acid solution on skin or in your eyes. If you accidentally do so, wash off immediately with
fresh water (or use the pool/spa water).
Please do not hesitate to contact your Eco-MATIC Dealer for any assistance regarding ‘Cell’ cleaning.

Maintenance of Your Eco-MATIC (Continued)
Maintaining The Salt Level
It is important to always maintain at least the minimum recommended salt level (4000 ppm for ESR models, 3000 ppm for
ESC models and 3000 ppm for ultra low salt ESR models) in the pool water (in some cases, spas can be operated at lower salt
levels – check with your Eco-MATIC Dealer). Follow the advice of your pool maintenance person and/or your pool contractor or
pool equipment supplier. Always maintain the specified minimum salt level for your Eco-MATIC model.
Operating your Eco-MATIC at lower than recommended salinity level will shorten the life of your ‘Cell’ and will void
warranties on the ‘Cell’. An excess of salt (up to 6000 ppm) is acceptable and will not harm the Eco-MATIC (in fact, the system
operates more efficiently at higher salt levels).
Checking The Salt Level
Your Eco-MATIC has a Low Salt Indicator (LED 2). When the level of salt in the water falls below the minimum level,
LED 2 will turn RED. The Unit will continue to produce sanitizer, but the situation should be corrected quickly. Otherwise the
Low Salinity Cut-Out will shut down the Eco-MATIC (if your product has this feature).
The Low Salt Indicator (LSI) has been factory calibrated (plus or minus) to the minimum salt level (4000 ppm for ESR,
3000 ppm for ESC and 3000 ppm for ultra low salt ESR models) so could therefore activate at slightly higher salinity than the
designed minimum salinity. If the LSI activates when you think there is sufficient salt in the water, a physical test kit measurement
of the salinity is necessary to determine the facts (before questioning the LED indicators).
Salt Test Kits
Under normal circumstances you should not need to measure (test) the salt level in the pool/spa water. If you believe that the
salt level may be exceedingly high, or if you do not trust the Low Salt Indicator on your Eco-MATIC, you may wish to measure
salt level.
Various ‘salt’ test kits are available, and less expensive salt test strips can be purchased at most pool stores (test strip
accuracy sometimes leaves a little to be desired). Some pool shops test for salt. You can also send water samples to your
Eco-MATIC Dealer for testing.
How Salt Is Lost From Your Pool
The Eco-MATIC process does not consume the salt – it merely re-uses it over and over. No salt is lost through evaporation.
However, salt is lost from the pool when water is lost – back-flushing filter, splash-out, overflow in rainy periods, leaks in
the pool.
Note: Some Eco-MATIC owners find it convenient to add 5 - 10 lbs of salt after each back-flushing of the filter.
Adding Salt To The Water
Salt is generally available in 25 lb, 40 lb, 50 lb or 80 lb bags - at places such as Lowe’s, Home Depot etc. Use ordinary rock
salt, evaporated ocean salt – the same as would be used for a water softener (avoid salt pellets). Call your Eco-MATIC Dealer if
you need assistance in locating a source of salt.
Add the salt by tipping it directly into the pool. Dissolve by sweeping the salt to the deep-end floor drain and/or by vacuuming
the pool. The heavier-than-water saline ‘syrup’ will remain on the floor of the pool if not mixed properly. Some pool owners like
to add a little salt (10 lbs or so) after each filter backwash.
How Much Top-up Salt To Add
When topping-up the salt level, we suggest adding salt at the rate of approx 100 lb per 10,000 gallons of water. Remember:
A slight excess of salt is not a problem, but too little salt causes damage to the ‘Cell’. When the added salt is dissolved, check
that LED 2 remains GREEN. Measure the salinity if in doubt. DO NOT continue to add salt if LED 1 and/or LED 2 remain RED.
Measure salinity before adding more salt to prevent over-salting the pool.

Maintenance of the Water
You should always be sure that your pool water is ‘in balance’. The person who maintains the pool should already be
checking and adjusting the water for the following. If you need verification of any of the following, take a water sample to your
local pool shop for testing (or send to your Eco-MATIC Dealer for testing).
Adding ‘chemicals’ To Your Pool
Your Eco-MATIC will eliminate the need for you to add ‘pool chlorine’, algaecides and ‘shock’ chemicals to the water. Many
pool owners and pool service people are in the habit of ‘shocking’ their pool water periodically, but this is no longer necessary
with Eco-MATIC and we advise against adding such chemicals (including copper-based algaecides, non-chlorine shock, etc). If
the need to add ‘pool chlorine’ should ever arise, you can do so without risk of harming your Eco-MATIC equipment.
In the event that your sanitizer level has fallen too low, or that you feel a need to ‘shock’ the pool, simply let your Eco-MATIC
operate at MAX output for an extended time (say for 24 hours).
Conditioner/Stabilizer
It is important to maintain 50 - 80 ppm of conditioner (cyanuric acid) in the pool water, in order to prevent the sunlight from
destroying the sanitizer (especially important in hot, sunny areas). If the conditioner level is too low, “good-bye sanitizer” – you
will find it difficult to maintain a good residual of sanitizer in the water – and your Eco-MATIC will need to work twice as hard as
it would if the conditioner level was correct.
pH Level
Pool water pH should be maintained in the range 7.2 - 7.8. At higher pH levels, the sanitizer loses its effectiveness, allowing
algae growth etc even though your Test Kit may indicate sufficient sanitizer in the water. If you have difficulty maintaining the pH
in the correct range, this is an indication that the Total Alkalinity (TA) is not at the correct level. It is always necessary to bring
the TA within the correct range before pH can be properly maintained.
Total Alkalinity (TA)
(TA) determines the speed and ease of pH change. TA can also greatly effect the frequency of having to clean the Eco-MATIC
‘Cell’. The ideal range for TA is generally 80 - 120 ppm, but really depends upon the Total Hardness (TH) of the water and
should be set at the level which suits the TH of your pool. The harder the water in a pool, the lower the TA should be. Your TA is
correct when the pH becomes stable and easy to maintain.
If the TA is TOO LOW If the TA is TOO HIGH
pH ‘bounce’ Almost constant acid demand
Stains on plaster walls Promotes ‘Cell’ scaling
Etching of plaster walls
Corrosion of metal parts
Total Hardness (TH)
The Total Hardness (not just calcium hardness) if too high, can promote rapid scaling of the Eco-MATIC ‘Cell’. TH also
determines the desired level of TA.
General Rule: If the pool water TH is greater than 500 ppm and is at least 300 ppm above the TH of the fill water
(tap water) - then dump the water and re-fill the pool.
Warning: Be aware that pools in high water-table areas should not be emptied without first consulting your
pool builder or pool service.
Note: All water balance parameters (Hardness, conditioner/stabilizer, pH, TA) should be maintained within the normal
recommended ranges.

Water Testing • What to Test For • Recommended Levels
Sanitizer (or ‘chlorine’)
Recommended Level 1.0 - 3.0 ppm
How to Test Normal ‘chlorine’ Test Kit (free-chlorine test)
Frequency of Testing Test and adjust daily, initially, until you achieve consistent readings. Then test at least weekly, or
whenever pool conditions or usage changes.
How to Adjust Use the Eco-MATIC System Control (and/or vary filter operating time, being sure to run filter at
least the recommended daily hours).
Why Sanitizer? Micro organisms, germs, algae want to grow in your pool water. Correct sanitizer levels (in
combination with other various levels) prevent the growth of such radicals and will maintain your
pool water in a healthy and safe condition.
Sanitizer Demand The amount of sanitizer required for your pool varies from time to time, depending upon such
factors as: the number of swimmers, water temperature, pool environment, hours of sunlight.
Total Alkalinity (TA)
Recommended Range 80 - 120 ppm. Note: Or follow the advice of our pool maintenance person and/or the contractor
who plastered your pool.
Correct level Depends upon the Total Hardness of the water. The harder the water, the lower the TA should be
kept. Check with your local pool service or pool supply store.
How to Test Normal 4-in-1 pool Test Kit. If your Test Kit does not have a TA Test, have your water tested by
your local pool store.
Frequency of Testing After initial adjustment, check every couple of weeks.
How to Adjust There are various methods of adjusting TA. Check with your local pool service or pool supply
store. Lowering TA is achieved by addition of ‘acid’. TA can be raised by adding sodium
bicarbonate (baking soda).
Why TA is Important TA determines the speed and ease of pH change (if you get the TA correct, pH control will become
very simple). TA level effects the frequency of ‘Cell’ scaling.
High TA Makes pH maintenance difficult. Increases potential for scale to form on ‘Cell’, on pool walls, etc.
Low TA Causes etching, staining of plaster pool walls, corrodes metals, makes pH control very difficult.
pH Level
Recommended Range 7.2 - 7.8
How to Test Normal pool Test Kit
Frequency of Testing If the Total Alkalinity (TA) is within the correct range for your pool, the pH will become more
stable - reducing the need to test frequently. Test at least weekly. If pH always needs adjusting,
check and adjust TA.
How to Adjust Lower pH by adding ‘pool acid’ (muriatic acid). Disperse acid by pouring into water around
perimeter of pool. Raise pH using baking soda.
Why pH is Important Properly maintained pH means much fewer pool problems. High pH reduces sanitizer efficiency
(makes it more difficult for the sanitizer to do its job) and increases scaling (on ‘Cell’ and on pool
walls etc). Low pH will cause etching of plaster pool walls, corrodes metal components, stains
pool walls, eye irritation, destruction of Alkalinity.
Conditioner, Stabilizer (Cyanuric acid)
Recommended Range 50 - 80 ppm (may vary in some areas)
How to Test Some pool Test Kits include this Test. You can also purchase a Cyanuric Acid Test Kit, or have your
pool service test for you, or take a water sample to your local pool supply store.
Frequency of Testing Once or twice per year is normal. More frequently if water is lost from pool by way of leaks,
splash-outs, etc.

14 714.384.0382
Water Testing • What to Test For • Recommended Levels (Continued)
Why Conditioner? Low levels of conditioner causes loss of sanitizer, especially in sunny locations. Low conditioner
levels mean your Eco-MATIC will have to work harder (produce more sanitizer) in order to
achieve and maintain correct sanitizer levels. Indoor pools need very low or no conditioner,
stabilizer, or cyanuric acid (some states have prohibited it’s use on indoor pools), check with your
local health department or pool supply store.
How to Adjust Add cyanuric acid to the water. Get instructions as to how to add conditioner from your pool
service or local pool supply store. Give 48 hours to dissolve, don’t backflush filter too soon.
Alternative is to dissolve into warm water and pour into pool. Another idea – get your pool service
to do it.
Total Hardness (TH)
Ideal Range Below 500 ppm
How to Test Some pool Test Kits include this Test. You can purchase Total Hardness Test Kits.
Frequency of Testing The water used to fill your pool has its own TH, depending upon its source. Over time, the TH of
the pool water will increase as the Hardness is left in the pool when water evaporates. Fill water
adds more Hardness. Test at least once or twice per year.
When to adjust TH If the TH of the pool water is greater than 500 ppm, and is 300 ppm above the TH of the fill water,
it is recommended that you dump the water and re-fill the pool.
How to Adjust TH Replacing the water is the only way to reduce the TH of the pool water. Be sure to consult your
pool builder or pool service before emptying your pool. Serious structural damage can result if
pools are emptied in certain ground conditions and ground water levels.
Calcium Hardness Always maintain calcium hardness within the range suggested by your pool builder or pool service.
Phosphates
Phosphates in swimming pool water can reduce the level and effectiveness of sanitizer in pools, causing the Eco-Matic to work
harder than necessary; any amount (over 50 ppb) of phosphate should be removed by using a phosphate-removing chemical
available at your local pool supple. We recommend having your pool water tested for phosphates annually to insure good
performance and long cell life.

Installation Summary
This is a quick guide as to how the ECO-MATIC should be installed. Refer to the following pages for detailed instructions and
helpful hints.
1. Install the ECO-MATIC ‘Cell’ into the return line, downstream from all other equipment. The ‘Cell’ must be horizontal. The
water flow direction through the cell housing should be ‘flowing away from the Cell Head’. Inlet and outlet piping to be a
minimum of 6” in length (to provide for easy Cell Housing replacement if this becomes necessary in the future). Refer to
following pages for details.
2. Mount the ‘Power Pack’ onto a wall, fence or post, etc., within reach of the ‘Cell’ cord. Connect to power so that ‘Power
Pack’ receives power only when the filter pump is operating (both components should switch on and off coincidentally).
Refer to following pages for important wiring instructions.
3. Connect ‘Cell’ to ‘Power Pack’. Refer to following pages for connection details.
4. Add salt to the pool water. Quantity of salt required (pounds) for regular ESR units = gallons of water x 0.0375. Quantity of
salt required (pounds) for ultra low salt ESR unit and ESC units = gallons of water x 0.0275. Refer to the following pages
regarding type of salt and how to dissolve.
The ‘Power Pack’
The ‘Power Pack’ (or Power Control) contains the
electrical components which transform the mains power
supply to the low voltage DC current required to operate
the ECO-MATIC ‘Cell’, as well as the other various operating
and control functions of the ECO-MATIC system.
The ‘Cell’
The ECO-MATIC ‘Cell’ is the component which comes
into contact with the pool/spa water and which, through a
process of electrolysis, produces (from the ‘natural’ salt
dissolved in the water) the sanitizer/oxidizer necessary
to maintain the water in a healthy condition. The ‘Cell’ is
comprised of sophisticated materials specifically designed
and engineered for ECO-MATIC’s intended purpose.
The Salt
A basic ingredient of the ECO-MATIC process is SALT
(nature’s own salt, pure evaporated ocean salt, or table salt – sodium chloride). The salt is added directly into the pool or spa
water to produce the water salinity required to enable your ECO-MATIC to function properly. The salt may or may not have been
included in the purchase price of your ECO-MATIC. Salt is available at most home improvement centers, hardware stores, etc,
usually in 50 lb, 40 lb or 25 lb bags – and is the same salt sold for use in most domestic water softeners, mostly referred to as
‘rock’ salt. Be sure to use ‘sodium chloride’ and not ‘potassium chloride’.
The Components of Your Eco-MATIC

www.balboadirect.com 17
The location in which the ‘Cell’ is to be installed is important. The ‘Cell’ must be located as follows:
* In the return-to-pool line (the pipe carrying filtered water back to the pool)
* AFTER (down-stream from) all other equipment (filter, heater etc). Contact your ECO-MATIC Dealer for instructions if the
‘Cell’ cannot be located AFTER all other equipment.
* Locate the ‘Cell’ so that its power supply cord (attached to ‘Power Pack’) can reach the ‘Cell’ from the ‘Power Pack’
location.
* The ‘Cell’ cord must be at least 5 feet distance from the inside walls of the pool/spa (at least 5 feet from the nearest water in
the pool/spa).
Other considerations regarding ‘Cell’ location:
When correctly installed, the ‘Cell’ will produce sanitizer only when water is flowing through it – and, obviously, the sanitizer
is carried in the water, to wherever the water is being directed, so ... If there is a spa attached to the pool, be sure to locate the
‘Cell’ in the line carrying water to the pool/spa, preferably before (upstream from) the valve which directs water flow to either
the pool or spa – and not after (downstream from) the valve in the line to the ‘spa only’ (in which case no sanitizer would be
sent to the pool during normal filtering periods).
IMPORTANT: Refer to your ECO-MATIC Owner’s Guide for important instructions – how to prevent over-
production of sanitizer in your spa.
If there is a solar heater attached to the pool, locate the ‘Cell’ so that it has water flowing through it whenever the filter pump
is operating regardless of whether water is flowing through the solar heater panels.
Choosing the ‘CELL’ Location
Before Installing Your Eco-MATIC...
How good is the water in your pool/spa?
In most instances, pools can be simply converted to the ECO-MATIC system without the need to change the pool water.
However, if the water is ‘old’ (older than say 3 years), or if the water has been subjected to high degrees of chemical dosing, or
has been kept in generally poor condition, you may want to consider dumping that water and refilling the pool.
Pool water has a tendency to become ‘harder’ over time. Evaporation leaves the ‘hardness’ in the water and when
top-up water is added to the pool, additional hardness is added. This additional hardness, together with residuals from
previous chemical treatments etc can make the pool generally more difficult to maintain (regardless of the purification method
being used).
A simple water hardness test (Total Hardness, not just calcium hardness) can determine whether it is preferable to dump the
water and refill. Although water hardness varies from one area to another, the following general rule can be used as a guide:
If the pool water Total Hardness exceeds 500 ppm (parts per million) AND is more than 300 ppm above that of the fill water
(tap water), it is recommended that you drain and refill the pool.
The same general rule applies to spas, however the smaller volume of water and relative ease of changing the water in a spa,
suggests that it is generally the advisable thing to do.
WARNING: Before emptying your pool or spa, consult your pool builder, Pool Service or local Pool Shop and determine
whether it is safe to do so. Emptying a pool in certain ground-water conditions can cause serious structural damage to the pool.
Note: Pools that have been sanitized with non-chlorine systems (bi-guinia or copper saged) should be drained and
refilled before converting to salt sanitation.

18 714.384.0382
Installing the ‘CELL HOUSING’
Once the correct location for the ‘Cell’ has been established, the
‘Cell Housing’ must be installed into the plumbing at that selected
location. The clear plastic ‘Cell Housing’ is PVC compatible, so
use ordinary PVC solvent (glue) to attach the ‘Cell Housing’ to the
pipework. Remove the ‘Cell’ from the ‘Cell Housing’ before attempting
to install the ‘Cell Housing’.
IMPORTANT The ‘Cell Housing’ must be installed as
follows:
* ‘Cell Housing’ must be installed in a HORIZONTAL position.
* Water flow should be in the direction indicated by the ARROW
on the clear plastic ‘Cell Housing’ (in the direction flowing away
from the ‘Cell’ head).
* The Inlet and outlet pipes must be pointing vertically DOWN, to
form an inverted ‘U’ configuration with the ‘Cell Housing’.
* The vertical inlet and outlet PVC piping must be a minimum of
6” in length (refer Sketches 3a, 3b)
* The ‘Cell Housing’ shall be free standing and not secured to any
rigid backing surface (such as a wall).
* Installation should allow easy removal of the cell from the
housing.
Water Flow: In most cases (for 1.5” and 2” PVC) the total water
flow can be directed through the ‘Cell Housing’ (as shown in Sketch 3a) without significantly effecting the flow rate and/or back-
pressure on the filter etc. However, if flow rate is a concern (high horse-power pump, large diameter piping etc), the ‘Cell’ can
be installed on a by-pass (as shown in Sketch 3b). Note the need for a valve to ensure a good flow of water through the by-pass.
Helpful HINT: When attaching the ‘Cell Housing’ into the pipework, attach the inlet and outlet pipes to the ‘Cell Housing’
FIRST – and then connect that assembly to the rest of the pipework (Refer Sketch #2). The inlet and outlet pipes should be
pushed in, twisted, and held firmly in place until the PVC solvent holds. Note: While making these joints, hold the ‘Cell Housing’
horizontally, with the inlet and outlet pointing down, so that the liquid PVC solvent does not run into the ‘Cell Housing’ where it
will look unsightly through the clear plastic.
Helpful HINT: Copper Pipes? Use PVC ‘Flow-Lock’ fittings (compression fittings) for easy connection of PVC to copper pipes.
Location of the ‘Power Pack’: Select a location to mount the ‘Power Pack’ onto a wall or fence etc, as follows:
* The ‘Cell’ location should already have been selected (see above). The ‘Cell’ power cord must reach the ‘Cell’ (with
sufficient slack to allow removal of the ‘Cell’ from the ‘Cell Housing’). Note: The ‘Cell’ cord can be extended if absolutely
necessary, but you must first contact your ECO-MATIC Dealer for important instructions.
* For cord-connected units, locate the ‘Power Pack’ so its cord is within reach of the point where it is to be connected to
mains power (eg: pool Timer).
* The ‘Power Pack’ is weather-proof so can be located outdoors.
* It is important to ensure that ‘Power Pack’ be located in a well ventilated area – and that air can circulate between the back
of the ‘Power Pack’ and the surface onto which it is mounted (stand-offs on back of ‘Power Pack’ provide ventilation for
wall-mounted units).
Once a suitable location for the ‘Power Pack’ has been selected, use 2 - #8 screws to attach ‘Power Pack’ to a wall, fence or
post etc (using wall plugs if necessary).
See actual size template on back page for mounting screw position.
Installing the ‘POWER PACK’

www.balboadirect.com 19
Connecting ‘POWER PACK’ to Power Supply
IMPORTANT: It is essential that your ECO-MATIC gets power ONLY WHEN THE FILTER PUMP IS ‘ON’ and water
is flowing through the ‘Cell’. The power supply to the ECO-MATIC Power Pack must therefore be controlled by the
same switch or timing device which controls power to the filter pump.
Voltage
Your ECO-MATIC ‘Power Pack’ has been designed to operate on either 110V or 220/240V AC. It cannot be switched from one
voltage to the other, so must be ordered in the same voltage as the power to your filter pump. Note: Units for larger pools are
available ONLY in 220/240V.
Cord Connected ‘Power Packs’
UL and C-UL Listed Power Packs will not be fitted with a power cord. Refer to Permanently Connected ‘Power Packs’, below.
‘Power Packs’ with cords should be connected as follows:
Cord wires will generally be BLACK, WHITE and GREEN, or BROWN, BLUE and GREEN.
For 220/240v units, connect Black and White to load, Green to Ground. For 110V units, connect Black to load,
White to neutral, Green to Ground.
Simply put, the power supply cord wires should be connected to the same Timer terminals as the filter pump – to insure that
the ‘Power Pack’ receives the same voltage as the filter pump, and is switched ON and OFF coincidentally with the filter pump.
For Permanently Connecting ‘Power Packs’. (refer Sketch 4)
Refer to IMPORTANT SAFETY INSTRUCTIONS at front of these instructions.
De-energize power supply circuit before connection to ‘Power Pack’.
Remove the ‘knock-out’ in the base of the ‘Power Pack’ (if not already
removed). The knock-out hole size will suit a standard conduit fitting.
Open the ‘Power Pack’ (see instructions below), remove attached cord
and connect replacement power supply wires to terminal block and GROUND
terminal (marked with standard GROUND symbol).
Bonding Lug Connection (if applicable)
If the ‘Power Pack’ comes with Bonding Lugs (USA one Bonding Lug, and in Canada two Bonding Lugs located externally on
the side of the ‘Power Pack’) they must be connected to the local common bonding grid (which includes all metal parts of the
swimming pool structure and to all electrical equipment, metal conduit and metal piping) in the area of the equipment, using
either insulated or bare copper conductor not smaller than No. 6 AWG.
Opening The ‘Power Pack’ (refer Sketch 5)
Always de-energize power supply circuit before opening ‘Power Pack’.
To open ‘Power Pack’ remove the 2 screws which hold removable panel in place. Remove the
panel and loosen the single screw inside the recess. The front panel of the ‘Power Pack’ can now
be removed by a) pulling bottom of front panel out (towards you), then b) slide the front panel
down (so front of front of top panel slides out from under top panel).
When opened, the front cover of the Power Pack should be supported, so as not to put any
strain on internal wiring, by connecting the front cover to the left hand side panel of the Power
Pack, using the clip provided (refer Sketch 5).
When replacing the front panel, be sure that all internal wiring is clear of the side and bottom panels, to allow proper seating
of the front panel. Insert sides of front panel into the slots at each side, slide the front panel UP so its top edge slides under the
top panel. When the front panel is in place, re-tighten screw and replace circular cover plate.
Connecting ‘Cell’ to ‘Power Pack’
The ‘Cell’ connecting lead is factory-attached to the ‘Power Pack’, with connectors at the end of the lead for attachment to
‘Cell’ head.
ESR – the 2 main connectors (BLACK and WHITE) push into the female fittings on the ‘Cell’ head (be sure to match colors).
The smaller connector (Gas Sensor) pushes on to the threaded bolt of the ‘Cell” head.
ESC – fit the BLACK connectors to either titanium rod. The BLUE Flow Sensor should be pushed onto the threaded shaft of the
small bolt.
