Welcome to the luxury of a salt water swimming pool
We are dedicated to providing you with the most luxurious pool water you have ever experienced, as well as the most
reliable product and solid after-sales service you could hope for.
Reading this Guide will help ensure that your ECO-matic generator 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 t he manufacturer. Please refer to the Trouble-Shooting section of this Guide before calling
your dealer.
Overview of the ECO-matic Salt Water Pool System
When salt 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, algae and other such organics which would othe rwise flourish in the water. This process recycles, so it
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 the sani tizer necessary to maintain your
pool/spa water by using and recycling a natural product – salt. Your ECO-matic will do exactly the same thing as ‘pool
chlorine’ would do.
*(HOCl the same effective sanitizer as would result if ‘pool chlorine’ was added to the water – but without them the
unpleasant aspects of chlorine compounds and without the need to handle them.)
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’), turn it
off immediately, contact your ECO-matic Dealer or the person who installed your ECO-matic immediately and ensure
that the fault is rectified.

General
This system is not intended for outdoor installation. If a pump/filter room is not available, a shelter providing shade and
weather protection will be necessary. Please note that the installation area should be well ventilated and free of
substances that could cause corrosion. Installation must be done in accordance with any local regulations AND
MUST BE PERFORMED BY AN AUTHORIZED ECOMATIC DEALER.
When deciding on the position of the unit, take care to allow for the cable lengths available. Approximate maximum
placement distances are:
Power Supply to Control Box – 1.5m (approximately 5ft)
Power Supply to Electrolytic Cell – 3m (approximately 10ft)
Control Box to Gas Sensor (Cell) – 4m (approximately 13 ft)
Actual distances will depend on how the cables between units are run. Check prior to installation. IMPORTANT: DO
NOT PLACE ANY COMPONENT NEAR SOURCES OF HEAT OR CHEMICAL VAPORS (e.g. ACIDDRUMS).
The Power Supply and Electrolytic Cell are very heavy, allow for this during installation. If any components are dropped,
damage will occur.
THE COMPONENTS OF YOUR ECOMATIC
Power Supply:
Should be wall mounted using brackets provided. The brackets provide a gap between the back of the unit and the wall
for air flow. The unit should be mounted at about head height. That is approximately 1.5 meters (approximately 5ft) above
ground level. The brackets are designed for masonry bolts/wall plugs. The unit can be lifted on/off.
Note: this unit is heavy. Please allow for this when installing.
Instructions for mounting bracket use are provided in the package containing the brackets.
Control Box
Should be mounted at approximately the same height as the Power Supply to allow easy access and viewing. This unit
has a “keyhole” mount at center/top/rear. Once the unit has been hung on this mount, two locating screws can be placed
at the bottom corners of the unit. These are under the lower cover plate on the front of the unit.
Electrolytic Cell Assembly
Should be installed vertically on its legs and placed down stream from the filter. The cell is heavy and great care should
be taken in fitting the legs. If the cell is dropped the internal housing can bedamaged.
Select the approximate position for the cell and screw the legs to the protruding bolts on the lower flange; space them
equally around the flange circumference.
The cell should be lifted and then maneuvered until it is vertical and resting its legs. At least 2 people will be required for
this operation. Do not attempt to pivot the cell on the legs, as they are not designed to carry a load in this way.
The cell is now ready to be plumbed into the pool system.
Back - up Sanitation
In the ev ent of a system failure or during periods of extreme bather l oads and/or very hot weat her, or due to local
authority regulations, extra chlorine may be required to maintain sanitation levels in the pool. Use Sodium Hypochlorite
(Liquid Chlorine) as an additional source of chlorine.

8
The extra chlorine can b e provided by a Dua l ORP Chemistry Controller, simple chlorine injection device such as a
chlorine pump/feeder, or by simply keeping enough chemical chlorine on hand to manually cope with an emergency. The
manufacturer does not recommend manually feeding chlorine.
Remember that the Electrolytic Cell will need to be replaced/ re-conditioned periodically and this may mean a small
amount of down - time for the system.
Minimum Flow Rates for Optimum Cell Efficiency
The following flow rate through the cell for the ECO-matic COMM 2400 Automatic Chlorine Generator
are recommended for optimum efficiency:

Note: While the flow rate stated is optimal, we understand that it is not feasible to achieve on a consistent basis. Please
keep flow rate as close to the minimum as possible while not exceeding maximum flow stated in the table.
Testing Cell Flow Rate
A flow meter must be installed into the cell line to verify correct flow.
A Rolachem flow meter 5-7.5cm (2” or 3”) should be installed into the cell line – one flow meter per installed ECO-matic.
Install the flow meter per manufacturer’s instructions on the 5-7.5cm (2” or 3”) by-pass line leading to the electrolytic cell.
ELECTROLYTIC CELL PLUMBING
The Electrolytic Cell has been designed to operate in a bypass on the pool return line. Water flow through the cell must
be in the flow range specified on page 4 and the water from the cell should be returned to the pool return line as quickly
as possible.
A sample line should be installed after the cell to allow testing of water from the Cell.
A clear viewing area is also usef ul to allow a visual check of electrolysis (cloudy water). A number of possible
installation methods follow:
SALTPRO PLUMBING
An in-line zinc anode called SaltPro should be installed in-line and will serve as a sacrificial component. It is housed in a
7.62cm slip tee with clear PVC for visual inspection.
Location:
The SaltPro should be glued in the bypass line prior to the electrolytic cell. Install one SaltPro per each body of water.
The anode itself shall have a permanently attached bonding lug which shall be connected to the main bonding loop with a
#8 bonding wire.
The SaltPro is fitted with a manual bleeder valve for the installer to ensure, post installation that the air is
removed from the tee and the zinc makes contact with the water flow

9
Simple Bypass Installation
In this installation the bypass valve is partially closed to force water into the cell bypass and back to the pool return. This
will increase the back pressure to the pool pump/filter but should not affect performance unless the pump/filter
performance is already poor. Note the use of the Gas Sensor, isolation valves and sample line. The sample line is a
simple tap used to collect a sample of cell effluent for chlorine residual testing.
The off-take should be after the cell, in the return line to avoid the possibility of air in the return line finding its way into the
cell (see diagram page 7). The installation of a section of clear pipe before or after the Gas Sensor is beneficial in
viewing water flow from the cell. This pipe must be suitable for chlorinated water.

10
Powered Bypass Installation: (If required to maintain flow through cell)
This installation uses a pump to create flow in the Cell bypass. Note the recommended sample line and optional clear
viewing pipe. Please also note that care must be taken at the suction point to avoid air entering the bypass.
IMPORTANT: The Bypass Pump must be electrically interlocked to the main pool pump(s). Further to this, a
Pressure Switch should be installed in the return line prior to the Cell Installation so that main pump(s) failure can be
detected and Chlorinator production turned off. See “Gas Sensor and Pressure Switch Installation”.

11
Gas Sensor and Pressure Switch Installation
The Gas Sensor should be installed after the Cell in the following manner:
If the water flow ceases, the gas produced in the cell will collect at the highest point – t he Gas Sensor – an d when
enough gas has been collected chlorine production will cease until flow is re stored. It is recommended that 4 x 4 5°
elbows be used for Gas Sensor Installation, with Gas Sensor mounted horizontally. Note that there are two pipe sizes
available for use with the Cell – 50mm/2” and 80mm/3”. Appropriate fittings and pipe will be required.
Note: A sample line after the Cell outlet is recommended to allow testing of the water leaving the Cell. A clear viewing
pipe before or after the Gas Sensor can also be useful for a visual check of the electrolysis within the cell – the water will
appear cloudy or effervescent when the cell is operating.
Use of Pressure Switch
The Gas Sensor has 2 x 6.3mm or ¼” spade terminals (male) on either side of its connecting lead. For manual operation
these should be connected together with the short lead provided. The normally open terminals of the Pressure Switch
must be connected to the Gas Sensor terminals:
Pressure Switch Position
NOTE: the Flow Sensor has a
50mm/2” BSP threaded end
for fitting into the water line.
The water line will be either
50mm/2” or 80mm/3” and so
appropriate fittings and pipe
will be required by the installer.
Generally there will be a T-
Piece and four 45 Elbows of
the appropriate size needed.
If a 3” to 2” threaded reducing
T-Piece is not available, a 3”
T-Piece can be used with a
slip fit 3” to 2” Threaded
reducing bush.
The flow sensor is always
mounted horizontally and in a
raised position to aid the
accumulation of gas from the
Cell.

12
The Pressure Switch must activate when the main pump(s) are on and de-activate when they are off (i.e. no
water flow). It should be placed after the electrolytic cell. Placing the Pressure Switch at a bend is best:
The thread fitting of the Pressure Switch is 3mm ( 1/8”) NPT and the unit can be sealed with Teflon thread tape.
The switch should be placed so that water leaks do not interfere with the electrical switch; that is the switch should be
mounted on the side or top of a pipe/fitting, not underneath.
Please note that the voltage at the Gas Sensor is isolated Extra Low Voltage and should not pose a shock hazard.
The Pressure Switch is adjustable for static pressure. There is a lo cking tab on i ts back – slide it up to allow the
adjustment ring to be rotated. Rotation direction is embossed on the switch.
ELECTRICAL CONNECTIONS
Mains Power
The Power Supply has a power cord attached to the left-hand side of its bottom panel. The Earth must be connected. The
General Purpose Outlet to which the unit is connected must be protected by a GFCI (see local electrical regulations). If
the supply cord is damaged it must be replaced by a similar cord according to local electrical regulations.
The electrical supply to the unit must be interlocked to the main pump(s). That is, if the main pump(s) are turned off,
so is power to the unit. This can be very important when the Powered Bypass Installation is used. The bypass pump
should also be interlocked to the main pump(s) supply.
A clean (insulated) ground must be provided to the Power Supply.
Cell Power

13
The cell has connections both top and bottom. These protrude through the cell housing. You will find that the black and
white cell cables are terminated in male plugs and brass blocks resembling terminal block mechanisms. Simply fit the
brass blocks to the cell connections. Ensure that the connections are connected tightly.
The male plugs should be inserted into their sockets on the right hand side of the bottom panel of the Power Supply. To
insert, simply push them in slowly until a click is heard, then gently try to pull them out. If they are locked in place the
connection is correct.
If it is necessary to disconnect the cable, push the connector in further until a click is heard and then remove the
connector. This should only be done when power to the cell is off as arcing can result. Arcing will damage the connector.
The connector should be kept clean to ensure long life.
Control Box
There are three connectors under the Control Panel (when it is mounted). From left to right, the first is for power and
other signals to and from the Power Supply. This connector should be inserted and locked in place first. Do not attempt to
connect the units with the power on - damage may result. The connectors are keyed and cannot be inserted the wrong
way. DO NOT FORCE THE CONNECTORS AS DAMAGE WILL RESULT – the pins and socket contacts can be forced
out of their positions if force is used to insert the connectors.
The second connector is for the Gas Sensor and should be connected only after the Gas Sensor has been installed. If
the Gas Sensor must be removed it should be disconnected first.
The third connector is for EXTERNAL CONTROL and is normally left capped. A connector is supplied (with a length of
lead) for interconnection to another controller, such as a timer or Chlo rine Controller. Please note that the external
controller must output 12 to 24V A.C./D.C. or have an isolated relay output (closed) to turn the Chlorinator on. Voltages in
excess of those detailed will damage the unit. To use the EXTERNAL CONTROL simply connect the correct wires to your
controller output. See EXTERNAL CONTROL detailed information further on in this manual.

14
Connecting the Chemistry Controller - External Control
EXTERNAL CONTROL is a means of controlling the unit’s operation from an external Chemistry Controller. The External
Control LED will be Red to show that the external controller has the Cell Power turned Off. Green shows the Cell Power
is turned On and that the external controller has energized the unit.
An EXTERNAL CONTROL Cable is supplied with the unit. The cable can be connected in a number of ways and extreme
care must be exercised when it is connected into any external control device. The EXTERNAL CONTROL will respond to
any input signal of 12V to 24V AC or DC (1 Watt maximum) – this input is electrically isolated from the unit –or a dry
contact or switch. The configuration for each connection type is shown below.
OPERATION OF THE ECOMATIC COMMERCIAL SYSTEM
The ECO-matic System passes an electrical current through an electrolytic cell filled with a flowing mild salt solution. The
electrolysis that takes place causes the production of chlorine.
Your ECO-matic System is made up of three main components:
1. Power Supply
2. Control Box (includes Gas Sensor)
3. Electrolytic Cell
We have outlined the operation of the Electrolytic Cell, the Power Supply and Control Box is detailed below:
Power Supply
This component houses all the high power, heat generating elements of the ECO-matic System. This enclosure should
remain closed at all times as mains voltages are present at some points - mostly on the left hand side of the enclosure.
Safety isolation and AC to DC current rectification takes place inside this unit. There are two heat sinks on either side the
enclosure which will become hot to the touch when operating. The inside of the enclosure is fan-cooled to help dissipate
heat generated by the transformer and other components.

15
Inside the lower portion of the Power Supply is a plastic enclosure with a clear cover. Inside the enclosure is the Power
Supply Control PCBA. It has a number of switches and displays that represent the operation of the Power Supply. The
operation of these Power Supply sub-systems will be described. It should be noted that the switches should be in
certain positions for normal operation and that any deviation from their normal positions during normal
operation may damage the unit. Read the following sections carefully and check switch positions before normal
operation commences.
(For more information on internal power supply information request document called “Large COMM Power Supply Control
Overview”.)
Control Box
This enclosure determines the operat ion of the ECO-matic Commercial System. The enclosure is
protected to IP68 to stop th e penetration of dust and/or corrosive/moist atmospheres. The
transparent door should be closed at all times other than when using the control panel.
The Control Box has a number of features:
Cell Production & Polarity Indicator
Shows the magnitude and polarity of the electrical current applied to the cell. The Cell
Production is shown as a percentage of maximum system output. It will read around 100
unless the unit is in Winter Mode, where it can read down to 65. If the Cell Power is off, it
will be blank. Polarity is shown as “+” (positive, forward) or “-” (negative, reverse)

16
Temperature Indicator
Displays the temperature of the water passing the Cell (in degrees Celsius). This temperature is monitored and used by
the Control Box to adjust the unit’s operation (see Winter Mode and High and Low Temperature Shutdown). The
temperature sensor is integrated into the Gas Sensor fitting.
Operation Switches - Control the Cell Power
OFF - Cell Power is not applied
RESET - resets all alarms and places unit into STANDBY mode.
Cell Power cannot be applied for approximately 2 minutes.
ON - allows Cell Power to be applied from 10% to 100% (all the time), or from
the EXTERNAL CONTROL input (see below).
The System Output Control operates by a form of Pulse Width Modulation. This form of control works by swit ching the
Cell current on and off over a period of time with the result that the system output is averaged. For example if the control
is set at 50(%) the unit will operate at its normal output for only half the time that the unit is on with the averaged output
being 50%.
Winter Mode Switch
When Winter Mode is selected the unit will adjust its output to suit the water temperature of the pool. The amount of
current that the Cell can draw is determined by the water conductivity, which in turn is influenced by salinity and water
temperature. As the water temperature falls, so does its conductivity. If there was no modification of the unit’s operation
this reduction in conductivity would result in the eventual shutdown of the unit via the Low Conductivity Shutdown. With
Winter Mode selected the output of the unit will reduce with temperature. The reduction with temperature will
approximately follow the table:
TEMPERATURE
% OUTPUT
> 72ºF
> 22ºC
100
< 70ºF
< 21ºC
85
< 64ºF
< 18ºC
75
< 59ºF
< 15ºC
70
< 54ºF
< 12ºC
65
When Winter Mode is in operation < 21C (70 ºF) approx, the display LED will be Blue. See also High and Low
Temperature Shutdown.
Stand By
Red shows that the unit is waiting to produce chlorine; this occurs at polarity reversal, RESET and power - up of the unit.
The STANDBY delay is approximately 2 minutes. After the delay the LED will be Green indicating readiness to produce
chlorine.
Cell Power LED
Red shows that the cell is not powered, Green shows that the cell is on. If the output is set at less than 100 the Cell will
turn on and off automatically. This is how the output is reduced.
FLOW/GAS LED
Red shows a problem with either water flow and/or a gas build up at the Gas Sensor. Green shows normal operation.
When Red, the Cell Power will be turned off until the problem is rectified.
Low Conductivity Display & Shutdown
This display consists of two LEDs, one to display LOW CONDUCTIVITY and the other to display the
LOW CONDUCTIVITY SHUTDOWN. The first LED will show Red when the conductivity falls below a
certain point. If the conductivity continues to fall the second LED will go Red and this will cut power to
the Cell until the probl em has been rectified. The LEDs will be Green for normal operation. In cases

17
where the water temperature is dropping the un it should be operated in Winter Mod e as low
temperatures can cause these alarms to operate. For more information read “Water Conductivity”.
Low Temperature Shutdown
Will be Blue if the water temperature falls below 10 - 12ºC (50 - 54°F). Cell Po wer is turn ed off to
protect the cell. At these temperatures people will not swim and algae cannot reproduce.
The filter can be run to keep the pool clean. When the temperature rises again the
Unit will turn back on automatically.
High Temperature Shutdown LED
Will be Red if the cell water temperature rises to approximately 45ºC (113°F)
This is a safety feature included as the Cell can heat water. In the unl ikely event of the failure of the
pressure switch in a Powered Bypass Installation, the water would heat up and cou ld possibly boil if
given enough time. When the cell water temperature exceeds approximately 45ºC (113°F), Cell
Power is turned off.
Please note that if the Cell Power has been turned off by any of the fault conditions, an
automated check procedure takes place approximately every 2 hours to see if the fault
conditions have been rectified. The use of RESET will also re -start the system to see if the
fault condition still exists.
WATER CONDUCTIVITY
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, backwashing and on bathers as they leave the
pool. The salt level is also reduced in an outdoor pool by rain, which causes dilution. Salt is not lost to
evaporation. As the salt level in the pool falls toward the minimum, the LOW CONDUCTIVITY LED
will turn Red. At this point the salt level should be tested and increased to 4,000ppm minimum. (Note
Maximum Salt level should be 5000ppm).
The addition of salt should not affect the ECO-matic as it is protected against overloads. If no action
is taken and the salt level continues to fall, the LOW CONDUCTIVITY SHUTDOWN will also turn Red
and turn off Cell Power.
The unit will not produce sanitizer in this state. It will turn ON approximately every 2 hours to
check if salt has been added. If salt has not been added the Cell will turn OFF again:
There are other factors that can cause the Unit to shutdown.
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.
2. Cold Water - cold pool water reduces the ability of a Cell to carry electrical current.
(Refer to Winter Mode). More salt can be added if desired.
3. Failing Cell - as the 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.

18
Please note that the Low Conductivity and Low Conductivity Shutdown are not like T.D.S.
meters, which are temperature com pensated Scientific Instruments. Their accur acy will be within
500ppm salinity and they are water temperature dependent, just as the Cell is.
WINTER MODE
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 CONDUCTIVITY and LOW CONDUCTIVITY SHUTDOWN 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 CO NDUCTIVITY and LOW CONDUCTIVITY SHUTDOWN to assu me that
the salinity has fallen even if the salinity has remained relatively constant.
When the temperature of the pool water drops, the Winter Mode Switch should be placed in AUTO
position (it can be left here all the time if desired).
This has two effects:
1. It alters the setting of the LOW CONDUCTIVITY and LOW CONDUCTIVITY
SHUTDOWN Systems.

CHEMISTRY FOR ECOMATIC COMMERCIAL
Salt
At startup of the Chlorinator System there must be at least 4,000ppm of salt (sodium chloride) in the pool water. The salt
level should not exceed 5,000ppm. This is simple to achieve if the following steps are taken:
(i) Know, with reasonable accuracy, the pool volume.
(ii) Measure the pool water TDS (Total Dissolved Solids or Conductivity) prior to adding salt.
Note: the Conductivity Meter should be calibrated for sodium chloride. NOTE: Do not use Rock Salt or salt which
contains YPS or Iodine. Salt should be Fine or Medium Grade Solar Salt at 99.4% PURE NaCl
(iii) Calculate the required start - up salt dose and add it to the pool. Adding 10 kg of salt per 10,000 litres will raise
the salt concentration by 1,000 ppm (e.g. In a pool with no salt, a 100,000 litre pool will need 450 kg of salt to reach 4,500
ppm).
•If the pool is already operating as a salt pool, simply add enough salt to bring the level to 4,500.

•Note: Fill water can have existing salt level. Test with Conductivity Meter
(iv) Backwash the filters and add the salt by dumping it along the deep end of the pool.
DO NOT load all the salt into one area, as it will take longer to dissolve.
During the time the salt is dissolving, do not backwash the filters. Heavier salted water
will tend to flow into the deep end of the pool and could be backwashed out via the bottom
drains. Brush salt to ensure mixing.
If the TDS (Conductivity) is higher than expected then the pool volume may have been over estimated. This is not a
cause for concern as more salt is far better than not enough! It is possible to lower the salt concentration by partially
draining the pool and refilling with fresh water. (Unless the salt level is above 7,000ppm - contact the factory).
It is possible to lower the salt concentration by partially draining the pool and refilling with fresh water.
Salt is effectively not consumed by the ECO-matic process - the salt is recycled.
Note: Always use an approved Digital Conductivity Meter to measure salt content.
IMPORTANT NOTE: Newly plastered pools should run on traditional chlorine to “cure” the plaster for at least 2
to 4 weeks before adding the salt. Consult with the Pool Company for exact timing to ensure you do not void
your warranty. Be sure to check local authority regulations for checking calcium buildup in thecell.
Pool Stabilizer (Cyanuric acid / Cyanurates)
(For Outdoor Pools Only- where allowed by local authority regulations)
(i) Measure the stabilizer level using an appropriate test kit. It should be between 15 and 25ppm.
(ii) If the pool has never had stabilizer added, then approx. 25ppm of stabilizer should be added. Follow the
directions for adding it or load it directly into the pool pump inlets.
IMPORTANT: Stabilizer is very slow to dissolve and if it is loaded into the
pump inlets it can sit in the filters for a number of days. If the filters are
backwashed it will be lost. Monitor the stabilizer prior to back washing.
(iii) If there is some stabilizer present, but it is below 25ppm, add enough to make up the 25ppm.
IMPORTANT: stabilizer is for use in outdoor pools only. It is used to reduce the loss of chlorine due to the effect
of sunlight. It should not be used in indoor pools as it may adversely affect pool chlorine demand.
Other Chemical Levels
The other chemical levels to be aware of are pH, Total Alkalinity and Calcium Hardness.
The manufacturer highly recommends that you test and balance your water to L.S. I. ( Langlier Saturation Index) daily.
Simply follow basic pool guidelines, bearing in mind the following:
Swimming pool Spa
Free available chlorine 1.0 - 3.0 ppm 3.0 - 5.0 ppm
pH 7.2 - 7.8 7.2 - 7.8
Total alkalinity 100 - 120 ppm 100 - 120 ppm
Calcium hardness 200 - 300 ppm 150 - 200 ppm
salt 4000 ppm 4000 ppm
(i) Very high Calcium Hardness with Magnesium present in the water may present a problem to the Self-
Cleaning properties of the system and therefore require
additional cell inspections and cleanings.
(ii) Phosphates: should be less than (<) 200 ppb (Parts per billion)

20
Phosphates are food for algae and will increase chlorine consumption thus shortening cell life if present in water.
Remove phosphates with Saltline approved Phosphate Remover.
Possible Chemistry Problems
(i) The use of sulphate containing chemicals may promote the production of oxygen compounds at the cell, which
can lead to slightly lower chlorine production, and the production of chemicals which can adversely affect ORP
probes. Chemicals to avoid
- Sulphuric acid and Sulphate flocking compounds
Note: the use of potassium monopersulphate is acceptable.
(ii) The use of quaternary ammonium compounds (Quats) as an
algaecide can promote turbidity (cloudiness). This is caused by the very high
chlorine levels in the cell reacting with the Quats compound. A common Quats
compound is
benzalkonium chloride (also known as alkyldimethylbenzylammonium chloride or ABDAC).
(iii) The use of Citric Acid as a “black spot remover” will cause the chlorine residual reading in the pool to fall to
zero for an extended period of time.
(iv) Hydrogen peroxide, peroxygen chemicals and peroxide in general do not interfere with the ECO-matic System
but can seriously affect the ORP probes (redox probes) on chlorine/redox/ORPcontrollers.
MAINTENANCE
DAILY
1. Ensure all indicator lights are Green in Control Box
2. Ensure fan is running in Power Supply.
3. Ensure all cords attached
4. Ensure water is balanced to L.S.I.
5. Ensure that chlorine levels are between 1-3 ppm of free available chlorine for swimming pools and 2-5 ppm of
free available chlorine for spas.
WEEKLY
1. Ensure Flow Rate to cell is to spec
2. Inspect SaltPro to see if it is being attacked (look for signs for erosion)
MONTHLY
1. Ensure all connections (especially DC Cords) are snug
2. Inspect cell for build-up between blades and clean only if necessary
SEMI ANNUALLY
1. Turn off Power Supply
2. Tighten all internal connections
