when the pumps are off.
• All boxes on your ECOLAB Aqua Balance Pure Comfort Mineral Pool &
Spa ® Model 5.0 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 (sodium hypochlorite), 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.

7
• 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.
• 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 Saline

PREPARING YOUR WATER BEFORE INSTALLATION
ECOLAB Aqua Balance Pure Comfort Mineral Pool & Spa ® Model 5.0 saline
chlorination systems 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 Aqua Balance Pure Comfort Mineral Pool & Spa ®
Model 5.0 system to operate correctly, sodium chloride (salt) must be added
directly to the pool at least 24 hours before the installation of the equipment.
5kg 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 Aqua Balance Pure Comfort Mineral Pool & Spa ® Model 5.0
system on;

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.
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 7.5 x 3.8 = Litres of water
For an oval and round shaped pool
Average length (m) x Average Width (m) x Average Depth (m) x 5.9 x 3.8 =
Litres of water

PLUMBING YOUR SYSTEM
Your ECOLAB Aqua Balance Pure Comfort Mineral Pool & Spa ® Model 5.0
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 Aqua Balance Pure Comfort Mineral Pool & Spa ® Model
5.0 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 Aqua
Balance Pure Comfort Mineral Pool & Spa ® Model 5.0 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 Aqua Balance Pure Comfort Mineral Pool & Spa ® Model 5.0
model has very specific wiring requirements based on its line voltage and
amperage draw.
• Model 5.0 operates at 110 – 120v. A power cord will be supplied out of the
power box. Plug this into any standard 110 – 120v outlet. As above, the
cord labeled ORP must be plugged into a controller, or a 120v outlet.
• Your ECOLAB Aqua Balance Pure Comfort Mineral Pool & Spa ®
Model 5.0 system must be wired to the main pump power supply, so that
if the pump is shut down, the power to your ECOLAB Aqua Balance Pure
Comfort Mineral Pool & Spa ® system is lost.

STARTING THE SYSTEM
Once your ECOLAB Aqua Balance Pure Comfort Mineral Pool & Spa ®
Model 5.0 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 Aqua Balance Pure Comfort Mineral Pool & Spa ®
Model 5.0 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 Aqua Balance Pure Comfort Mineral Pool & Spa ®
Model 5.0 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 Aqua Balance Pure Comfort Mineral Pool & Spa ® Model 5.0
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:
➢5.0 - 25 amps @ 15v
• Water flow through the ECOLAB Aqua Balance Pure Comfort Mineral
Pool & Spa ® Model 5.0 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 Aqua Balance Pure Comfort Mineral
Pool & Spa ® Model 5.0 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.

17
MAINTENANCE AND CLEANING
Your ECOLAB Aqua Balance Pure Comfort Mineral Pool & Spa ® Model 5.0
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 5000 ppm 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 Aqua
Balance Pure Comfort Mineral Pool & Spa ® Model 5.0 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.)
1. Muriatic acid is corrosive, please follow safety instructions and wear
protective clothing.
2. To avoid splash, always ADD MURIATIC ACID TO WATER rather than
water to muriatic acid.
• Remember, the titanium plates that make up the cell are the most
expensive part of the ECOLAB Aqua Balance Pure Comfort Mineral
Pool & Spa ® Model 5.0 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 Aqua Balance Pure Comfort Mineral Pool & Spa ® Model 5.0 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.
