WARNINGS

This manual contains important information about the installation,
operation and safe use of this product, and should be given to the
owner and/or operator of this equipment. When installing and using
this electrical equipment, basic safety precautions should always
be followed. Failure to follow safety warnings and instructions in
this manual can result in serious injury and/or damage to your
equipment. Read and follow all warnings and instructions.

● The power supply internally contains live electrical components. There is a danger
of electric shock if opened.

● If the carton or product has been damaged or is wet: do not install the product,
contact your Pool Pro stockist.

● The product must be installed in accordance with AS/NZS 3000 Wiring Standards
and must be installed at least 3.5m away from the pool.

● CHLORINE GAS BUILDUP CAN OCCUR WITH IMPROPER WIRING: To reduce
the risk of personal injury, the power pack is designed so that the electrolytic cell
will only receive power when the pool pump is on. Otherwise, dangerous chlorine
gas build-up can occur. If the pump is not installed to the AC Socket (pump outlet)
on the power pack then the installer must ensure that the electrolytic cell is never

energised when the pool pump is OFF or water is not owing through the unit. A

venturi pipe is installed within the cell housing to eliminate any possible gas build
up, however it is RECOMMENDED that the cell housing be installed horizontally to
create a natural gas trap that acts as a safety device. Installation in any other way
may cause explosion, injury or death if the installer does not allow for gas removal.

● If you perform a backwash manually (without using the Backwash function on the
chlorinator) you must turn the chlorinator’s output down to the lowest percentage
setting via the “Chlor Setting” function.

● The pump rating must not exceed 8amps.

● Salt water may damage electrical components in the power pack.

● We DO NOT recommend the use of valves on the inlet or outlet of the cell housing.
If you do use a valve it is important that the valve cannot deadhead (lock closed)
while the pump is running. It is the installer’s responsibility to ensure some form of

ow control is installed in this instance and it disables the pump.

● Ideal salt levels range between 3000-3500ppm (parts per million). Salt levels
below 3000ppm and above 4000ppm may damage equipment and void any
warranty.

● Do not permit children, or persons with reduced physical, sensory or mental
capabilities to use or perform maintenance on this product. To reduce the risk of
accidents or incidents, service on the unit should only be performed by your local
Pool Pro Professional.

PREPARING THE POOL

Have your pool water tested by your local Pool Pro Professional. Ideal salt levels
range between 3000-3500ppm (parts per million). Salt levels below 3000ppm and
above 4000ppm may damage equipment and void any warranty.

For new pool installations, consult your pool builder or your local Pool Pro Professional
before adding salt. Some pool builders do not recommend the addition of salt for a
period of time following completion of the swimming pool.

Use Pool Pro Ultrane Pool Salt or Pool Pro Premium Pool Salt at the rate of 3.5kg
per 1000L of pool water. Mineral/magnesium chloride salts can also be used, including
Neptune Mineral Salt. Add 20%-30% extra product for mineral/magnesium salts.

Add salt to the shallow end of the pool. Use a pool brush to completely dissolve the

salt. Run the pool pump in the rst 8-12 hours to also help dissolve the salt.

NOTE: Never add salt/minerals directly to the skimmer box. High concentrations
of salt/minerals passing through pool equipment may cause damage. Remove
automatic pool cleaner from the pool before adding salt or other chemicals.

INSTALLING THE CELL

Check the O-Ring is installed in the cell housing and use a silicone based lubricant
(do not use petroleum based lubricants). It is recommended that the cell is installed

horizontally and the direction of water ow through the cell housing is entering from the

closed end of the cell housing and exiting from the end closest to the cell locking ring
(to reduce water hammer). Use pressure PVC solvent cement to glue cell unions to the
pipework. The cell must be installed so it is the last piece of equipment in the return line
to the pool.

A shut-off valve on the inlet or outlet of the cell housing is NOT recommended. If a
valve is required, it is recommended to install a non-return valve.

INSTALLING THE CHLORINATOR POWER PACK

The power pack must be installed outside of the pool zone, no more than 1.5m from
the cell, at least 1m above ground, away from chemicals and fertilisers (fumes may
damage the power pack) and in accordance with AS/NZS 3000 Wiring Standards.

Mount the power pack with the mounting bracket, green plugs and screws provided,
in a well ventilated position away from direct sunlight and rain (not in a closed

unventilated shed). If mounting on a post, install a waterproof non-metal at panel as a

backing plate.

Connect the lead from the cell electrode to the cell plug under the power pack, ensuring

a rm snap lock connection.

Plug the power pack into a 3 pin 10Amp weatherproof, RCD (Residual Current Device)
protected socket as per the AS/NZS 3000 Wiring Standards. Plug pump into the AC
socket at the bottom of the power pack.

instructions on the packaging of each chemical. Always add chemicals to water, never
add water to chemicals.

MAINTENANCE

General Maintenance

1. Never cover the chlorinator unit with towels or similar. The chlorinator has air vents

to keep it cool. Covering the vents may cause damage to the chlorinator.

2. The chlorinator should always be in an undercover area away from the elements.

3. The chlorinator should never be in a closed shed or similar environment near

chemicals or fertilisers. Fumes from chemicals and fertilisers may cause damage to
the chlorinator and may void the warranty.

4. Annually check all plug connections are tight and in sound condition.

Cell Maintenance

The cell may require cleaning if it contains debris or is being used in an area with hard
water. Hard water can cause calcium build-up on the cell, the sensor, or the cell plates.

1. Press the button to OFF.

2. Switch off the chlorinator and unplug at the power point.

3. Unscrew the cell’s locking ring and remove the cell’s electrode.

4. Check for pool debris, especially after backwashing. Check for calcium build-up on

the electrode. Do not scratch or bend the cell plates.

5. If calcium build-up is present, use Pool Pro Cell Cleaner to clean the cell. We do

not recommend the use of Hydrochloric Acid to clean the cell.

6. Check the cell’s O-Ring is clean, greased with silicone grease (never use

petroleum based lubricants) and securely located in the cell housing.

7. Reinstall the cell into the housing and hand tighten the locking ring securely.

8. Plug the chlorinator into the power point and press the button to turn the

chlorinator on. The chlorinator will return to its previous settings.

Power Pack Maintenance

1. Ensure the chlorinator is plugged into a weatherproof RCD protected 10amp outlet.

2. Ensure the pool pump is plugged into the bottom AC socket of the chlorinator unit.

3. Check all plugs and cords for damage. If any are damaged, they must be replaced

by the manufacturer or a similar qualied person. If the chlorinator is hard wired, a
qualied electrician is required.

4. Periodically turn the chlorinator off and apply an insect surface spray on the WALL

or POST that the chlorinator is mounted to, to keep insects from entering the
chlorinator unit. DO NOT spray directly into the air vents or on the chlorinator unit.
