THE CHROME SALT WATER CHLORINATION SYSTEM
Congratulations on your choice of CHROME salt water chlorinator system for your swimming
pool. The CHROME salt water chlorinator you have purchased is designed for easy and simplistic
operation and maintenance. By following these instructions you are assured years of trouble
free operation.
These instructions have been compiled and produced to help you get the maximum results
from your unit and to assist you to fully understand and correctly operate your CHROME salt
water chlorinator.
Please take the time to read these instructions thoroughly before attempting to operate your unit.
Should you require additional information or further assistance, please do not hesitate to contact
your local CHROME representative or visit our website www.aiswater.com.au.
ADDITION OF SALT
For best results the salt concentration in the pool water is required to be within an average
range of approximately 4,500 to 5,500 parts per million (ppm). These gures are temperature
dependant. In summer time, as water temperatures rise, salt levels may require slight reduction
while in winter time the reverse may be true to allow optimum performance of your unit.
The amount of salt required to achieve the desired level is determined by the capacity of the
pool. By measuring your pool and multiplying the average length by the average width by the
average depth you can easily establish this. This will give you your pool’s water capacity in
cubic metres. Multiply this by 4.2 and you will get the amount of salt (in kilograms) needed to
adequately achieve the required dosage for your pool capacity.
SPECIAL NOTE:
Please remember that your salt water chlorinator is not designed to chemically maintain
your pool water and keep it balanced, but rather to produce chlorine from a mild salt
solution within the water.
We encourage regular water testing, balancing and correction if & when required to
maintain the recommended stability levels of your pool water. This is a vital part of a
complete maintenance program and will ensure trouble free chlorinator performance as
well as a healthy and sparkling clean pool.
For example: Pool size = 9 metres by 4.5 metres by 1.6 metres in depth
Multiply 9 x 4.5 x 1.6 = 64.8 (cubic metres of water)
Multiply 64.8 x 4.2 = 272.16 (salt required in kilograms)

Using only rened swimming pool salt add the desired quantity to the swimming pool
water. To assist in the rapid dissolving and mixing, sweep or brush the solids until they are
fully dissolved. Undissolved salt may result in staining your pool nish.
As salt is heavier than water it will continue to lie at the deepest point of your pool, even though
the salt granules themselves have fully dissolved. In order to ensure adequate and permanent
distribution of salt throughout the pool water, we recommend additional sweeping and lter
operation over a 12 – 24 hour period.
Whilst adding the original salt and prior to commissioning your CHROME unit, and when
adding future salt supplies to your pool, please ensure that your chlorinator power supply
is switched o to prevent overload situations and/or damage to the cell electrode plates
or power supply.
WATER BALANCE
As previously advised, for best performance and operation of your CHROME salt water
chlorination system, certain water balances must be maintained within your swimming
pool. Please check your pool water and ensure that your chemical balances are within the
following guidelines.
· Chlorine 1.5ppm-2.0ppm
· pH 7.2-7.4
· TA (Total Alkalinity) 80ppm -120ppm
· Hardness, 150-350ppm;
· Cyanuric acid, 30ppm-50ppm;
· Phosphate, 0-500ppb;
· Salt 5,000 ppm
Adjust your pool water balance to achieve the above levels. Your local pool shop can assist
here to give you accurate readings and aid in correct dosages as necessary.
SPECIAL NOTE:
Contrary to popular belief, the action of your CHROME salt water chlorinator does not
use up the salt content of your pool water. In eect as the water is passed over the cell
plates, the salt is electrolysed and converted into sodium hypochlorite (chlorine).
This sanitises your pool water and converts back into salt - basically a never-ending
cycle. However salt loss will occur through swimmer action, lter back washing and wet
weather conditions.
This salt needs to be replaced periodically for your chlorinator to operate at maximum
capacity. Your local pool shop can advise you the correct salt dosage required to maintain
saline levels at recommended guidelines.

SPECIAL NOTE ON CHLORINE:
Your salt water chlorinator is not designed to bring your pool from a zero chlorine reading
to an acceptable level but rather to maintain acceptable levels. Should it become necessary
due to unforeseen circumstances (such as the unlikely event of chlorinator malfunction,
severe weather patterns, or massive use of the swimming pool) that you nd your pool
requires additional chlorine then chlorine should be manually added rather than running
your lter and chlorinator excessively to replace the lost chlorine. Doing this could put your
chlorinator and cell under unnecessary strain which could shorten their lives.
In situations such as this we recommend the use of liquid chlorine (sodium hypochlorite)
to supplement and maintain chlorine levels. The use of dry stabilised chlorine (calcium
hypochlorite) is not recommended unless liquid chlorine is unavailable and even then only
in limited amounts.
FITTING THE CHLORINATOR CELL HOUSING
The CHROME salt water cell housing must be plumbed into the return line of the pool lter
system after the lter and any diversion valves. Please refer to the installation diagram and
plumbing outline for the correct method of installation (Fig. 2).
In situations where a heater is incorporated, the CHROME housing must be installed after the
heater. Should a solar heating system be installed, the housing must be plumbed after the solar
diverters and after the water exits the solar system and rejoins the main stream pool return line.
Please note that your cell housing has been manufactured so that 40 mm PVC pipe will t both
inlet and outlet ports internally, and 50 mm couplings will t externally. This allows the use of
either 40 mm or 50 mm PVC pipes in the pool return line.

• The build up of gas occurs when water continues to . run into
the electrode housing after the pump is turned o. The gas
trap displaces water around the sensor terminal, which then
turns o the chlorine generator power supply and sounds the
“water ow” alarm
• Shown in diagrams is the correct way to implement a gas trap
INSTALLING THE POWER SUPPLY
The CHROME power supply is mounted on a wall using the mounting bracket and ttings
supplied. After securing the bracket in the appropriate position relative to your needs, the
power supply is hung on the bracket and locked into position by ensuring that the unit slips
into the slots provided on the mounting bracket.
It is preferable that the power supply is mounted in a location where it is protected from
accidental water spray and inclement weather. It is strongly recommended that the unit
is also protected and screened from the harsh sun, but in such a way that air ows freely
through the structure and does not impede the natural airow through the power supply.
You should also ensure that the power supply is not used as a shelf to store or pack objects,
as this can also impede the air ow, causing overheating and/or damage to the unit that is
not covered by warranty.
Mount the power supply so that you can see and reach the various controls and so that the cell
lead has a comfortable margin to reach the cell terminal posts. Our recommendation is that the
power supply is mounted slightly higher and to one side of the lter plant to allow easy access
(refer to Fig. 3).

CIRCUIT BREAKER
Every CHROME chlorinator has a circuit breaker located on the front panel of the unit.
The circuit breaker is designed to trip out in the event of a power surge or power overload.
When tripped the centre button will pop out shutting down the unit to prevent damage. To
reset and resume chlorination of your pool the centre button of the circuit breaker must be
pressed in to allow normal operations to proceed. Mains power to the unit must be turned o
prior to resetting the circuit breaker.
Should the circuit breaker continue to trip after this exercise then you should consult your local
CHROME representative for assistance.
ON/OFF SWITCH - NON TIMER MODELS ONLY
The on/o switch is located on the front panel and has been incorporated to allow you to
switch o the chlorinator function should you so desire. Please note that this switch will only
shut down the chlorinator operation. It will not aect the normal lter functions which will
continue to operate at the pre selected times you have chosen.
POWER SUPPLY CONTROL FUNCTIONS
Your CHROME salt water chlorination system has been designed for simplistic operation and
control. The functions and controls (both standard and optional) and their various operations
will give you a greater understanding and knowledge of the control and maintenance of both
your CHROME unit and your pool (refer to Fig. 3 for controls).

PUMP OUTPUT SOCKET
A 240 volt pump output power socket is supplied and located on the right hand underside of
the power supply. Your pool pump power supply lead should be plugged into this socket so that
when the time clock switches at your designated times both the salt water chlorinator and pool
pump will activate in unison.
Do not attempt to operate the chlorinator power supply with the pool pump lead disconnected
as this will lead to a gas build-up inside the cell housing causing it to overheat resulting in
damage to your chlorinator equipment that is not covered by warranty. In extreme cases gas
build-up may also cause the cell housing to rupture and explode, as it is not built to withstand
this type of pressure, possibly resulting in personal injury.
The pump socket is designed to operate a single pool pump of maximum 1.5 hp (horse power)
only. Do not attempt to operate any equipment other than your pool pump from this socket as
damage might occur to the power supply unit that is not covered under warranty.
WARNING INDICATOR LIGHTS
(FIG. 1, ITEMS 1, 2, 3 & 4)
There are four (4) warning indicator lights located on the front of your chlorinator. These
advise at a glance the status of the chlorinator power supply and, when illuminated they
indicate and advise about the situation that the chlorinator’s electronic monitoring system
has detected. The lights and their functions are listed below.
1. ORANGE LIGHT: SALT HIGHER THAN NECESSARY
no action required
When illuminated this indicates that you have exceeded recommended salt levels. As long
as this is not causing your chlorinator to overload no further action or reduction of salt
concentration is required at this point. No further salt should be added if this light is illuminated.
2. ORANGE LIGHT: STEADY CELL OFF
chlorinator on standby
FLASHING SALT LOW
add salt and/or clean cell
STEADY – When illuminated in a STEADY continuous light your chlorine production has been
switched o by turning the chlorine controller anti clockwise and your chlorinator power supply
is now in a standby mode. Turn the chlorine controller clockwise to resume normal operation.
FLASHING – If the light is illuminated and FLASHING the monitoring system has detected low
salt levels and this will need to be adjusted for the chlorinator to operate at maximum capacity.
This light will also ash if the cell has reached a point where its output is below the normal
operating output. Please refer to the section detailing the addition of salt to your pool.

WARNING INDICATOR LIGHTS ...continued
(FIG. 1, ITEMS 1,2,3 & 4)
3. RED LIGHT: STEADY POWER ON
FLASHING NO WATER FLOW
chlorinator on standby
STEADY – During normal operation this light will remain STEADY, indicating that power is on
and the chlorinator is operating correctly.
FLASHING – When FLASHING the monitoring system has detected a water ow problem and
has shut down to prevent damage. It will also be accompanied by a beeping alarm alerting you
of this situation. When problem is rectied normal operation will resume.
4. RED LIGHT: STEADY OVERLOAD
OFF NORMAL OPERATION
in forward cycle
FLASHING NORMAL OPERATION
in reverse cycle
STEADY – When this light is illuminated and STEADY it will also be accompanied by a beeping
alarm alerting you of this situation. The chlorinator has overloaded and shut down to prevent
any damage. A direct short between two of the electrode plates coming into contact with
each other could cause this, or a foreign object could be shorting out two or more plates. It
can also be caused by a massively high concentration of salt in the pool water. Depending
on the problem and rectication required, normal operations can proceed. Please note that
the chlorinator power supply must be switched o and then on again to reset the electronic
circuitry and resume operations.
OFF – When this light is o, the chlorinator is operating correctly in forward cycle mode.
FLASHING – When illuminated and FLASHING the chlorinator is operating correctly in
reverse cycle mode.
SPECIAL NOTE ON WARNING INDICATOR LIGHTS:
When your chlorinator is operating in forward polarity cycle, light number 3 (Fig. 1, item 3)
is on and steady while light number 4 (Fig. 1, item 4) is o.
When your chlorinator is operating in reverse polarity cycle, light number 3 remains on and
steady while light number 4 will ash.
