SAFETY INFORMATION
PLEASE READ THE FOLLOWING SAFETY INFORMATION CAREFULLY!
WARNING!
• Only a certified technician may install and service your ECOLAB system.
• Modifying your ECOLAB system in anyway may cause bodily injury and will
void your warranty.
• Warning: To reduce the risk of injury, do not allow children to operate this
device.
• Do not use this device with bromide products.
• Only replace components with those specified by manufacturer.
• When installing your system, ensure that power is linked to the main pump
power source for the pool to ensure that your ECOLAB system never operates
when the pumps are off.
• All boxes on your ECOLAB system contain high voltage components.
Never open any box while power is “on”.
• WARNING: Heavy pool (and/or spa) usage, and higher temperatures may
require higher chlorine output to maintain proper free available chlorine
residuals.
• If additional chlorine is required due to heavy bather loads, use granular or
liquid chlorine to maintain appropriate chlorine residual in the water.
• Maintaining high salt and chlorine levels above recommended range can
contribute to corrosion of pool (and/or spa) equipment.
• DO NOT add pool (and/or spa) chemicals directly to the skimmer. This
may damage the cell.
• Check the expiry date of the test kit as results may be inaccurate if used
after that date.

7
• When replacing the cell, only use replacement cells having a label that
clearly states that it is a replacement cell for the chlorine generating
device ECOLAB Aqua Balance Pure Comfort Mineral Pool & Spa System,
Model CHLOR-25, REGISTRATION NUMBER 28816, PEST CONTROL
PRODUCTS ACT.
• Follow all aspects of the local and National Electrical Code(s) when
installing ECOLAB model CHLOR-25.
• NOTE: For outdoor pools, chlorine residuals can be protected from
destruction by sunlight by addition of stabilizer (cyanuric acid).
• NOTE FOR USE ON SPAS: For proper sanitation, spas must be
completely drained periodically. The number of days between COMPLETE
DRAINAGE is equal to the volume of spa water in litres, divided by 10
times the maximum number of daily spa users. Refill spa with water and
repeat DIRECTIONS FOR USE of the device.
• HEALTH AND HYPERTHERMIA WARNINGS FOR SPA DEVICES:
➢ People with a medical condition should consult a physician before
entering pool or spa water.
➢ Maximum spa water usage temperature is 40 degrees C. Bathing in
spa water at 40 degrees C should not exceed 15 minutes.

PREPARING YOUR WATER BEFORE INSTALLATION
ECOLAB Aqua Balance Pure Comfort Mineral Pool & Spa System operate by utilizing
the sodium chloride that has been added to the pool water, to produce sodium
hypochlorite (liquid chlorine), through the process of electrolysis.
In order for your ECOLAB system to operate correctly, sodium chloride (salt) must
be added directly to the pool at least 24 hours before the installation of the equipment.
5 kg of sodium chloride must be added for every 1,000 litres of pool water (ie: a
200,000-litre pool will require 1,000 kg of salt for start-up).
It is best to add the salt around the pool, and not load all salt in one section.
Once the salt has been added, brush the surface of the pool continuously until
the salt has all dissolved. You must never leave large amounts of salt on the
surface of the pool, as this may cause damage to the pool surface.
When you add the initial load of salt, you will need to add additional chlorine, as
the salt will cause a chlorine demand.
Your pool water should be balanced in the following range before turning your
ECOLAB system on;
Water balance parameters

NOTE: Low salt levels will cause a reduction in chlorine production and will
damage the device. High salt levels will increase the possibility of corrosion on
pool equipment.
NOTE: If too much salt has been added, dilute with fresh water.

9
Use standard test kits to check water chemistry, and use either a conductivity
tester or salt test strip to check saline levels.
(Note that most conductivity testers require frequent calibration to ensure
accurate readings, failure to calibrate the equipment will result in
inaccurate readings.)
How to Calculate volume of a pool
For a rectangular shaped pool
Length (m) x Width (m) x Average Depth (m) x 1000 = Litres of water
For an oval shaped pool
Length (m) x Width (m) x Average Depth (m) x 0.785 x 1000 = Litres of water
For an oval shaped pool
Diameter (m) x Diameter (m) x Average Depth (m) x 0.785 x 1000 = Litres of
water

PLUMBING YOUR SYSTEM
12
Your ECOLAB system can be plumbed using two different methods. Both will work
fine, however, the following must be taken into account before making the decision
of what method to use.
1. Your ECOLAB system requires a minimum of 75 Lpm of flow through the cell to
produce the rated amount of chlorine. Be sure that if you use the pressure drop
plumbing method [1] you have sufficient pressure drop across your filter to adequately
flow 75 Lpm through the cell.
2. When using the pressure drop plumbing method [1], you are sending
un-filtered water through the cell, so you need to ensure that you clean the
included strainer at least 1 time per week to remove any debris. Failure to
clean the strainer will result in a lack of flow, reducing chlorine production, and
ultimately reducing flow to the point that the flow switch de-activates the
system.
3. If you elect to use the bypass plumbing method [2], you will need to purchase
a butterfly valve based on the size of the pipe you are using. This can
sometimes be cost prohibitive, but the upside of this plumbing method is that
you are sending filtered water through the cell, which reduces the frequency of
needing to clean the strainer. Bypass plumbing method [2] also generally
allows for more flow through the cell, which is recommended.
4. Remember, always ensure that the return line from the Ecolab cell is
plumbed after the heater. Never plumb the return line before the heater, as
you will be sending a high ppm of chlorine through heater, which may cause
damage.
5. No matter which plumbing method you use, you will always have to plumb the
cooling line into box 3 (rectifier) using filtered water. This cooling line allows
the heat sink in box 3 to cool the critical components.

ELECTRICAL SPECIFICATIONS
Each Ecolab model has very specific wiring requirements based on its line
voltage and amperage draw.
• Model CHLOR-25 operates at 208 – 240v requiring advanced wiring,
which should only be done by a qualified electrician. 208 – 240v power
needs to be run from your main breaker panel to a safety switch, then into
the Ecolab main power box 1. As above, the cord labeled ORP must
be plugged into a controller, or a 120v outlet.
• Your ECOLAB system must be wired to the main pump power supply,
so that if the pump is shut down, the power to your ECOLAB system is
lost.

STARTING THE SYSTEM
Once your ECOLAB system has been successfully wired and plumbed, it is ready
for use.
• Make sure that the valves to and from the cell are in the open position.
• Make sure that you have water flowing through the water-cooled heat sink
in box 3.
• Ensure that the cord labeled ORP is either plugged into a controller or
directly into a 110v outlet
1. Move the safety switch to the “on” position.
2. Wait 10 seconds for the system to respond.
3. Turn the black knob on the side of box 1 clockwise, and watch the
amp or voltmeter on box 3 slowly increase.
(If your system is linked to an automatic ORP controller, we suggest you
turn the system to maximum, which will allow for full production every time
the controller calls for it. If you are running your system manually, you will
need to find the point at which you keep a satisfactory level of chlorine in
the water. It may take several days to find this point.)
• If your ECOLAB system is linked to an automatic controller, remember
that it will only work when the controller is in feed mode. It is also a good
idea to make sure that your controller is not set in proportional band mode,
instead try using double set point control (if your controller supports this
function). An example of this is if you want to maintain a 700 ORP, have the
controller set to turn on at 695 ORP and turn off at 705 ORP, that way your
ECOLAB system is not switching on and off all the time.
(Call the manufacturer of your controller if you are having difficulties in
comprehending the saline chlorination system set up instructions. Most
controllers also require a “gold tip” ORP probe when working with a saline
chlorination system.)

16
GENERAL OPERATION
Your ECOLAB system operates when power is activated by the main pumps,
and from your ORP controller, and will continue to operate for as long as power is
applied from those two sources.
• The system has an output range of 5-100% of the rated chlorine
production, and can be adjusted by turning the black knob of the side of
box 1 in a clockwise or anti-clockwise motion. When adjusting the control
knob on the side of box 1, you will notice the amperage needle of the
gauge on box 3 increases or decreases.
Higher amperage = higher chlorine production.
Normal operating amps and volts for this model device are:
➢ Chlor-25 - 125amps @ 15v
• Water flow through the Ecolab cell is critical. Whether you plumbed
your system in using the pressure drop or bypass method, please ensure
that you have at least 75 Lpm through the cell to achieve the rated
chlorine production.
** Remember, your ECOLAB system is a chlorine generator, and will
only operate as well as you maintain it. Careful attention must always
be paid to proper chemical balancing, and regular service.

Your ECOLAB system is designed to operate 24/7 at max power, and will give you
years of trouble free use if you follow these basic maintenance and cleaning
instructions.
• Remember, this system produces sodium hypochlorite “liquid
chlorine” from the salt that you have added to the water. It will only
continue to operate correctly if salt is maintained at the correct
5000ppm level. Low salt will lower the amount of chlorine produced,
and cause damage to the electrolytic cell. (Warranty’s will not be
honored if it is determined that salt has been run low.)
• There is a strainer mounted at the bottom of your Ecolab cell, which
will trap debris and stop it from entering the cell, this strainer needs
to be cleaned regularly.
• The plates that are inside the PVC cell housing are the most critical
part of the system. You will notice that over time a white substance
(calcium minerals) will build up on the plates, especially at the top of
the cell. This buildup needs to be cleaned by removing the cell from
the housing and soaking it in a dilute muriatic solution (1:5) for about
10 – 15 minutes. Reverse polarity systems will need to be cleaned
every 3 – 6 months. (Warranty’s will not be honored if it is determined that
the cell has not been cleaned regularly.)
• Remember, the titanium plates that make up the cell are the most
expensive part of the ECOLAB system and are going to need to be
replaced roughly every 15,000 hours of operating time. By
ensuring that salt is always at the correct level, and plates are
cleaned regularly, you will increase their “life”, thus saving you
money…
Ecolab Inc. offers a wide range of other products that can help you
maintain salt levels in your pool, including conductivity controllers and
saturated salt feeders for those pools that lose large amounts of water.
