IMPORTANT NOTICE:
FACTORS THAT WILL IMPROVE THE PERFORMANCE & LIFE OF YOUR SALT WATER CHLORINATOR
PLEASE READ THIS BEFORE OPERATING YOUR CHLORINATOR
POOL BUILDERS: Please cover this information with your customer during the new pool ÒHand over
SessionÓ
Salt Water Chlorinators are a valuable piece of pool sanitising equipment and must be cared for to get the
best performance and life span from it.
There are THREE main factors that will damage your chlorinator and reduce the life of the product. Please
monitor the following factors in accordance with your installation & operating instructions.
1. MAINTAIN RECOMMENDED SALT LEVELS:
RECOMMENDED OPERATING RANGE: 4500-6000ppm
¥ Run chlorinator at the Salt Levels stated within this document and on the product to ensure
optimum sanitiser output and cell life.
¥ Operating this device at low salt levels will damage the cell and reduce its life.
¥ The control panel displays a red 'Add Salt(LED indicator warning when the salt level is too low.
¥ If no action is taken to rectify the salt levels, damage to the cell may result which will not be covered
under warranty.
2. MONITOR & MAINTAIN YOUR CHLORINATOR CELL:
EcoSalt REDOX has a ÒReverse PolarityÓ In-Line cell.
¥ To keep your salt water chlorinator in the best possible condition, regular monitoring of the electrolytic
In-Line cell is recommended. The ÔCellÕ is the transparent plastic housing containing the electrode plates.
¥ During the chlorination process a white powdery Calcium scale may naturally build up on the plates in
the cell. Monitor the cell to prevent excessive scale build up. Excessive scale build up will cause
damage to your cell, and dramatically reduce its efficiency and lifespan.
¥ Reverse Polarity models have low maintenance cells that minimise scale build up.
¥ If the salt level is correct and the 'Add Salt(LED indicator warning is displayed, the cell may require cleaning.
¥ If Calcium scale builds up please clean the cell, following the cleaning instructions provided on page 12.
¥ NEVER: Use concentrated acid to clean your cell.
¥ NEVER: Leave cell in cleaning solution for extended periods of time
¥ NEVER: Use metal implements, scourers or brushes to clean your cell
3. BALANCED POOL WATER CHEMISTRY:
¥ Salt levels MUST be maintained at 4500-6000ppm for optimum performance and lifespan
¥ Calcium Hardness levels MUST be kept to ideal ranges of 200-275ppm (for Concrete and Tiled Pools)
and 100-225ppm (for other surfaces) to prevent excessive scale build up and damage to equipment
¥ pH levels MUST be kept to ideal levels to prevent damage to equipment and pool surfaces and to
obtain optimum sanitiser effectiveness.
¥ Total Alkalinity and Stabiliser levels MUST also be kept in an ideal range.
Note: Please refer to the RECOMMENDED POOL WATER CHEMISTRY chart on page 15 for more
information.

Installation Instructions for EcoSalt REDOX
INSTALLING THE POWER SUPPLY:
Select a convenient well-ventilated location within one metre of filter equipment and mount the Power
Supply vertically onto a dedicated pool equipment wall or post 1.5 metres above ground level. The Power
Supply should not be located within 3 meters of the pool water.
Hardwire the Power Supply cord into a suitable weatherproof outlet as per local standards and local
government regulatory requirements. The Power Supply may be interlocked to switch on/off with the pump
via an external timer, or simply powered at all times.
Two self-tapping screws and wall plugs have been provided for fast and simple installation. The drawing on
page 17 shows the dimensions between the drill entry points. Use a 6mm masonry drill bit when fitting the
power supply to a brick or concrete wall. When mounting to a post drill pilot holes and fit screws provided.
Once screws are in position simply hang chlorinator via mounting slots at the rear of the top panel.
Note: the additional mounting slot at the base can be used to help secure the unit.
INSTALLING THE IN-LINE CELL:
The Cell can be installed vertically or horizontally in a position that allows for easy removal and cleaning.
The Cell MUST be positioned after all accessories such as heater or pool cleaner, but before it divides if
there is more than one return to pool line.
NOTE: The ORP Probe and Manifold MUST be installed prior to the Cell and at least 200mm from the Cell
inlet.
NOTE: The Power Supply must be kept away from acid and other chemical storage areas. Acid and
chemical vapours will corrode the electronics inside the Unit. It must also be kept away from heat sources.
Good ventilation is necessary for correct operation.
IMPORTANT: If the chlorinator must be mounted!horizontally (Face Up), due to installation
restrictions, it must be fully sheltered so that water does not enter the unit. If water enters the
chlorinator when mounted in this position the warranty will be void.

Installation Instructions for EcoSalt REDOX
CONNECTING THE IN-LINE ELECTROLYTIC CELL TO THE POWER SUPPLY:
The EcoSaltREDOX uses a reverse polarity In-Line Electrolytic Cell for low maintenance operation. The
EcoSalt REDOX Power Supply is fitted with a flexible lead terminated with connectors. These must be
correctly fitted to the connections on the Cell. Fit black connectors to the outer titanium rods and the white
connector to the middle titanium rod, as shown below:
CONNECTING THE FLOW SWITCH AND ORP PROBE TO THE POWER SUPPLY:
The EcoSalt REDOX is supplied with a Manifold for installation of the Flow Switch and ORP Probe. The
Manifold MUST be installed after the Filter and at least 200mm prior to the Cell inlet, as shown in the
diagram on page 6. The Flow Switch is to be hardwired into the terminal block located within the lower front
panel of the Power Supply, as shown below:
The ORP probe is connected via the socket at the base of the Power Supply.
NOTE: Use thread seal tape to ensure all threaded fittings are watertight.
IMPORTANT: The terminal block in the front panel is only to be used for connection of the supplied
flow switch. The flow switch must be mounted with the arrow on the switch pointing in the
direction of water flow.

Pre-Start Up Procedures
Before operating your EcoSalt REDOX please ensure the following items have been added to your pool:
¥ SALT - Load salt into the pool at the rate of 45-60kg per 10,000 litres to achieve a recommended salt
level of 4500 - 6000ppm.
Connect manual vacuum system and slowly vacuum until salt dispersal is complete. Place vacuum head into
deepest end of pool and allow vacuum to continue for a further 2 or 3 hours. Salt should now be completely
mixed. Never add salt directly into skimmer box.
¥ CHLORINE - For a new pool installation that has not been chlorinated, add sufficient Chlorine (liquid or
granular) to achieve a reading of 3 ppm (with a suitable test kit), or run the chlorinator system continuously
for at least 24 hours or until a reading of 3 ppm is reached.
¥ STABILISER - It is essential that pool stabiliser be added to outdoor pools and maintained at the rate of
15 - 20 ppm at all times. Do not exceed 100 ppm.
(Refer Day to Day Operation page 13 for further information).
Setting and Operating Your
EcoSalt REDOX System
CONTROL PANEL LAYOUT
1. To set your EcoSalt REDOX first ensure the pH (7.2-7.6) and Total Alkalinity (80-150ppm) are balanced,
then add chlorine whilst the unit is running to reach your desired level of chlorine (1.5-3.0ppm). Verify this
with a reliable test kit or seek the advice of your pool professional.
2. Once the desired level of chlorine is reached turn the ORP CONTROL dial slowly clockwise or anti-clockwise
as required until the green 'Within Range(LED indicator is displayed and the 'Cell Power(LED turns off. As
an alternative to the above procedure you can set the ORP CONTROL to the halfway or 12 o(clock position
(this is approximately 650mV) and run the spa until the ORP within range LED is on and Cell Power is off.
Check sanitiser levels and adjust ORP CONTROL to suit.
3. If a higher or lower chlorine residual is required you can adjust the ORP CONTROL up or down (this should
be done in small increments).
4. Your EcoSalt REDOX must have water flow to operate. It is recommended that your Pool filtration system
run for a minimum of 4 to 8 hours per day to enable the EcoSalt REDOX to maintain the required sanitiser
level. In hot weather and with a larger number of people using the pool, the required filtration time may be
longer.

!
,!
Setting and Operating Your EcoSalt REDOX System
5. If the green 'Within Range(LED indicator is not achieved during your daily filtration cycle, you need to either
increase the filtration time or follow the trouble shooting procedures on page 16.
6. Whilst the pump is off there will be no flow and the red 'No Flow(LED will be displayed. This is normal, in this
state the ORP REDOX LED may indicate 'Under(or 'Within range(or 'Over(. There is some overlap of the
ORP REDOX LED(s -it is possible for the 'Within Range(and 'Over(or 'Under(LED(s to be on at the same
time.
7. The green 'Cell Power(LED indicator will only operate when the system is actually producing sanitiser.
8. If the red 'Add Salt(LED indicator is displayed you need to top up your salt level to at least 4,500ppm. The
'Add Salt(indicator is also affected by water temperature, as is the unit output. The EcoSalt REDOX is
designed for optimum operation with 20-30!C water temperature. If water temperature is less than 20.C you
may require additional salt to turn off the ADD SALT Indicator.
9. What is ORP?
EcoSalt REDOX uses an ORP Probe to determine whether or not chlorine needs to be produced to sanitise the
pool. ORP levels are measured in millivolts (mV). The ORP Probe does not measure the actual chlorine level of
your pool, it measures the effectiveness of the chlorine to oxidise and kill biological contaminants.
Note: It is possible for two pools with identical chlorine residuals to have very different ORP levels. This is due to
the effectiveness of chlorine in a pool being reliant on other factors such as pH, stabiliser levels, total dissolved
solids (TDS), combined chlorine levels and temperature.
In general ORP will be affected in the following ways:
Chemical Level
ORP Level
Chlorine UP
UP
pH UP
DOWN
pH DOWN
UP
Stabiliser UP
DOWN
Combined Chlorine (Chloramines) UP
DOWN
Total Dissolved Solids* UP
DOWN
Temperature UP
UP
* TDS other than Salt
10. Please note your EcoSalt REDOX Cell is a reverse polarity type designed to clean itself periodically. To
clean itself the EcoSalt REDOX will shut down for a few minutes and then reverse the polarity of its cell
plates. In hard water areas you may need to remove and clean the cell manually, following the cleaning
instructions provided on page 12.

EcoSalt REDOX Special Features
ORP CONTROL:
This dial is used to set the level of sanitiser (chlorine) you would like to be maintained in the pool.
CELL POWER:
This green LED indicator is displayed when power is being applied to the cell.
NO FLOW:
This red LED indicator is displayed when there is a Ôno water flowÕ or Ôlow water flowÕ condition; this is
detected by the supplied flow switch.
If a Ôno or low flowÕ condition is detected, check pump and pipes for blockage or damage and check that the
flow sensor is connected and installed properly.
ADD SALT:
This red LED indicator is displayed when the salt level in the pool drops below a certain level. As the salt
level in the pool decreases, the wear on the Cell increases. At this point the salt level should be increased
by adding 10kg of salt per 10,000 litres of pool water.
The addition of salt should not affect the EcoSalt REDOX as it is protected against overloads. If no action is
taken and the salt level continues to fall, damage to the cell may result.
Although salt is not consumed in the chlorination 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.
There are other factors that can cause an ÔAdd SaltÕ indication:
1. Heavy Rain Ð can cause very dilute pool water to pass over the Cell due to surface skimming.
2. Scaled Cell Ð a scaled Cell will not draw as much electrical current as a clean Cell. Refer to
MAINTENANCE OF THE IN-LINE ELECTROLYTIC CELL on page 11.
3. Cold Water Ð cold pool water reduces the ability of a Cell to carry electrical current. Addition of salt can
help compensate for cold water.
4. Failing Cell Ð 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. Please note that the ÔAdd SaltÕ Indicator is not like T.D.S. meters, which are
temperature compensated Scientific Instruments. The accuracy will be within 500ppm salinity and is
water temperature dependent, just as the Cell is.
ORP REDOX:
Under Ð This red LED indicator is displayed when the sanitiser is below the level set by the ORP
CONTROL dial.
Within Range Ð This green LED indicator is displayed when the sanitiser is at the level set by the ORP
CONTROL dial.
Over Ð This red LED indicator is displayed when the sanitiser is above the level set by the ORP CONTROL
dial.

EcoSalt REDOX System Maintenance
MAINTENANCE OF THE POWER SUPPLY:
Little or no maintenance is normally required with the exception of replacing blown Fuses. These Fuses can
be sourced from your local Davey Dealer. However it is essential that the wall or post to which the power
supply is installed be sprayed (not the unit itself) periodically with a good surface type insect repellent, since
penetration by insects may cause damage, which is not covered by your warranty.
IMPORTANT: Your EcoSalt REDOX should be calibrated regularly following the Setting and
Operating Instructions on page 8, to ensure the desired level of chlorine is maintained.
NOTE: The back of the Power Supply has been designed as a heat sink. It is normal for this area to become
very hot.
MAINTENANCE OF THE IN-LINE ELECTROLYTIC CELL:
The cell is composed of precious materials, and although proper maintenance can prolong its life to the
maximum, eventually the process of electrolysis will wear away its delicate coating, at which time it
gradually ceases to produce chlorine.
Mineral salts and calcium (scale) are deposited on the outer and the inner plates as electrolysis takes
place. This build-up will interfere with the flow of electrical current in the Cell and thus lowers sanitiser
production. It is essential to inspect the Cell regularly and clean when necessary. The rate at which
deposits will form on the plates differs with each pool and can be influenced by the following:
¥ Calcium hardness of the water
¥ Water Temperature
¥ pH level
¥ Water which has been chlorinated with calcium hypochlorite for an extended period
¥ Calcium in the plaster surfaces of a concrete pool
Because these conditions vary so much, check the Cell at least weekly to begin with to see when either
scale or a blue/green soapy substance appears on the plate. You will then be able to determine the
cleaning cycle necessary for your pool (more frequent cleaning may be required in summer). The intervals
between cleaning could get longer to the point where cleaning is only necessary a couple of times each
year. One exception is the use of bore water or ground water, in which case cleaning may always need to
be as frequent as once a week.
The life of EcoSalt REDOX electrolytic cells vary substantially from one installation to another due to
variations in operating time, water quality and composition, system and cell maintenance. Please
ensure that when cell replacement is necessary you use the correct genuine EcoSalt replacement cell
to match your system. The correct EcoSalt replacement cell to use is shown in the table below:
EcoSalt REDOX: Reverse Polarity Cell
Model
Replacement Cell Code
MC12ORP
M0696
ALWAYS INSIST ON GENUINE ECOSALT REPLACEMENT PARTS. If it is necessary to replace the
In-Line Electrolytic Cell, beware of Òlook alikesÓ. Only the Genuine EcoSalt Cell is designed and
warranted to operate with the EcoSalt REDOX Power Supply.
SERIOUS DAMAGE MAY RESULT TO THE ELECTRONICS INSIDE THE UNIT IF COPY CELLS ARE
USED AND MAY VOID WARRANTY.
IMPORTANT: If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent or similarly qualified persons in order to avoid a hazard.
NOTE:
In areas with hard water, reverse polarity systems may require occasional manual cleaning.

EcoSalt REDOX System Maintenance
To clean the EcoSalt REDOX In-Line cell: Ensure that power to the pump and chlorinator is turned off Ð
failure to do so may result in the pool pump turning on while the cell is not in place. Disconnect the cell lead
from the cell and remove the cell from the pool return line by undoing the unions (take care not to lose the
O-rings).
!
METHOD 1 Ð
Add 1 part HYDROCHLORIC ACID to 10 parts WATER in a suitable sized container. The Cell should be
placed vertically in the container of solution ensuring that it is deep enough to cover the cell plates. Take
care when doing this as the solution can foam and create a spill which must be cleaned up by dilution. As
an alternative you can clean the cell by purchasing a suitable blanking cap (Davey P/N MK102118) which is
fitted to one end of the cell. Secure the cell in an upright position and fill with solution from the open end.
METHOD 2 Ð
As an alternative, an approved commercial cell cleaning solution can be used a number of times effectively.
When clean, the cell should be rinsed thoroughly and the connections should be dried carefully to avoid
connector corrosion. It should not take longer than a few minutes to clean; if it does the cell should be
cleaned more frequently. Return the cell to its position in the pipe work and re-connect.
SAFETY DEVICE:
Hydrogen Gas is a by-product of the chlorine producing process. A Flow Switch has been supplied with the
unit, which will switch off chlorine production if low or no flow is detected.
EcoSalt REDOX units are also fitted with a Thermal Cut-out to prevent overheating. If the temperature rise
is too high, power is automatically disconnected. The Unit will resume operation when it cools down.
MAINTENANCE OF THE ORP PROBE:
The ORP Probe must be kept clean and free of oils, mineral deposits, and contamination in order to
function properly. Cleaning requirements vary depending on bather load and pool water conditions (amount
of contaminants/debris), we recommend cleaning every 3-6 months. If there is an increased need to
calibrate your EcoSalt REDOX unit, the ORP Probe probably requires cleaning or replacement.
To clean the ORP Probe, ensure power to the pump and chlorinator is turned off, then disconnect the
Probe from the Power Supply and remove from the Manifold. The ORP Probe tip can then be gently
cleaned with a soft toothbrush and regular tooth paste; a mild detergent may also be used to remove any
oil. After cleaning the ORP Probe should be thoroughly rinsed with fresh water, and new thread seal tape
applied before reinstalling into the Manifold.
NOTE: If cleaning does not restore correct operation, the ORP Probe may require replacement.
IMPORTANT: Probe tip must be kept wet at all times, it must not be allowed to dry out or permanent
damage will result.

!
"$!
DaytoDayOperation
Four Prime rules must be observed if your unit is to give the best possible service:
4. STABILISER
The importance of pool stabiliser in outdoor pools cannot be over-emphasised. It is essential in helping
retain chlorine in your pool. Chlorine is rapidly dissipated by sunlight and the use of stabiliser will reduce this
dissipation substantially. Without stabiliser, it may be necessary to run the Unit for up to three times as long!
water. Stabiliser should be maintained at a level of 15 to 20 ppm. Before adding more stabiliser, have your
pool water analysed at your pool shop to ensure that you do not add too much. Stabiliser is NOT
recommended for indoor pools.
5. pH AND TOTAL ALKALINITY:
A correct pH level must be maintained to prevent problems such as black spot, staining, cloudy water, etc.
An incorrect pH level can damage the pool. Correct pH levels are as follows; Fibreglass Ð 7.2 to 7.4 Concrete
& tiled Ð 7.4 to 7.6. If you allow the pH level to rise to 8.0 or above, the chlorine required could be as much as
three times the normal amount.
Total Alkalinity should not be confused with pH, although the two are closely related. Total Alkalinity
determines the speed and ease of pH change. The ideal range is 80 to 150 ppm, or refer to your pool
professional.
You should use a test kit which includes a test for Total Alkalinity. Low Total Alkalinity can cause unstable pH
levels Ð i.e. an inability to keep the pH constant may cause staining, etching and corrosion of metals. High
Total Alkalinity will cause constantly high pH levels.
IMPORTANT: For the ORP control to function correctly, pH and Total Alkalinity MUST be maintained
at the correct levels.
6. SALT LEVELS:
Salt is the essential element by which your Unit operates. Not enough salt means not enough chlorine Ð this
simple rule governs the total operation of your EcoSaltª REDOX, and insufficient salt will damage your Cell.
RECOMMENDED SALT LEVEL RANGE: 4500 - 6000ppm
Salt is NOT used up in the process of producing chlorine or by evaporation. Salt is only lost through
backwashing, splash-out, overflow or by leakage from the pool or plumbing. Heavy rain can dilute the salt
solution in your pool; therefore salt levels should be checked during this season.
Low salt levels will destroy the coating on the Anode plates and will void all Warranty.
The EcoSalt REDOX has a built in warning indicator to minimise damage resulting from insufficient salt
levels, however, the ultimate responsibility is on the owner to ensure adequate salt levels are maintained all
year round.
Warning: Some people recommend that you put salt directly in the skimmer box. This is a
very poor practice as it allows very high concentrations of salt to be passed through your
filtration and other pool equipment.
Warning:
Do not add Hydrogen Peroxide to pool water or through swimming pool hydraulic or
sanitiser system. Use of Hydrogen Peroxide will void warranty on Davey products.

!
"%!
7. RUNNING TIMES:
These instructions cover EcoSalt REDOX for residential use only.
The filtration pump needs to be run for a minimum of 8 hours per day during summer to ensure the proper
filtration of your pool.
IMPORTANT: The EcoSalt REDOX guarantee does not apply to commercial or semi-commercial
installations, i.e. where the system runs more than an average of 8 hours per day over the year.
Guarantee on commercial and semi-commercial installations is 12 months only on both power
supply and cells.
Chlorine Production
The EcoSalt REDOX must be run daily to generate sufficient chlorine to sanitise the pool. The EcoSalt
REDOX will automatically regulate the amount of chlorine production to ensure the sanitation of your pool.
The amount of chlorine produced is dependent on the setpoint and the run time of the filtration pump
If the chlorine level is too low the ORP CONTROL needs to be adjusted. If the chlorine level is still too low
after adjustment the run time of the filtration pump may need to be increased. Harsh local conditions such as
pollution or wind borne dust require different running times Ð in which case, seek advice from your pool
professional. Without sufficient filtration/chlorination, your pool will never function correctly. ALWAYS RUN
THE FILTER WHEN SWIMMING IN THE POOL. In extremely hot weather or during periods of heavy
bathing loads, the filtration time may need to be extended.
In some cases you may find your chlorine level to be too high. To determine if this is the case, run your filter
and chlorinator for the suggested times and ORP levels and test your pool water on the morning after
operation. If your chlorine test shows a high level of chlorine, the ORP CONTROL can be turned anti -
clockwise. Test your chlorine level again the following morning at around the same time. If your chlorine level
is still high, further reduce the ORP CONTROL.
ÒSHOCKÓ TREATMENT:
Periodically, especially during extremely hot conditions, it may be necessary to boost the amount of chlorine
in your pool in order to maintain absolute sanitation of the water. This can be achieved by adding either liquid
or granulated chlorine. If granulated chlorine is added, the Cell must be checked regularly, since the
additives from this product will clog the electrodes.
CHLORINE TYPES AND COMPARISONS / MAX POOL SIZE:
Many chlorinator manufacturers calibrate their units to compare with 65% granulated chlorine, making it
necessary to adjust their readings to a lower level in order to determine true chlorine production. Below is a
comparison table of the available types of chlorine used to sanitise pools.

NOTE: The appropriate chlorinator size for your pool is dependent on the local climate and the
bather load of the pool. Please note that chlorinator cell life can be increased with shorter
running times during winter and lower output settings. Davey recommends that a chlorinator
is run for between 6 - 8 hours a day during summer, and 4 hours during winter.

COMMON TERMS:
Algae - Microscopic forms of plant life which enter the pool by rain, wind and dust. There are numerous varieties
- some are free floating whilst others grow on walls and in cracks and come in different colours. Some are
more resistant to chemical treatment than others.
Bacteria - The germs that contaminate your pool. Introduced by swimmers, dust, rain storms and
other elements.
Balanced Water - The correct ratio of mineral content and pH level that prevents pool water from being-
corrosive or scale forming.
Chloramines - Compounds formed when chlorine combines with nitrogen from urine, perspiration, etc.
Chloramines cause eye and skin irritation, as well as unpleasant odours.
Chlorine Demand - The chlorine required to destroy germs, algae and other contaminants in the pool.
Chlorine Residual - The amount of chlorine remaining after chlorine demand has been satisfied. This is the
reading obtained with your test kit.
Cyanuric Acid - Also known as stabiliser or conditioner. It reduces dissipation of chlorine by direct sunlight.
Liquid Acid - Chemical used to reduce the pH and total alkalinity in the pool water, and for cleaning
chlorinator Cell.
ppm - An abbreviation for Parts Per Million the accepted measurement of chemical concentration in
swimming pool water. 1ppm = 1mg/L.
