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)

5
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.

6
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.

10
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.

11
CHLORINE CONTROLLER
(FIG. 1, ITEM 5)
The chlorine controller regulates the amount of chlorine production relevant to the position it has
been set to. By adjusting the chlorine controller clockwise you increase chlorine manufacture and
by turning anti clockwise you reduce production. Do not attempt to turn the controller beyond its
stops as this could cause damage to your unit that is not covered by warranty.
CHLORINE OUTPUT INDICATOR
(FIG. 1, ITEM 6)
Your power supply is tted with ten green indicator lights set in a crescent shaped formation.
During operation of your chlorinator these lights will illuminate relevant to the degree at which
the chlorine controls have been adjusted. Working in conjunction with the chlorine controller
you can increase or decrease chlorine output to suit your pool’s requirements. As you increase
the output, (by turning the control knob clockwise), the corresponding lights will illuminate
progressively to 100% (ten lights).
You have full control of chlorine production merely by adjusting the chlorine controller and
illuminating the number of lights to satisfy your chlorine demand. Each light represents 10%
(one light) of capable chlorine production up to its maximum output of 100% (ten lights).
TIME CLOCK OPERATIONS (TIMER MODELS ONLY)
(FIG. 1, ITEM 7)
The standard timer (model A-TB72) when tted to your chlorinator is designed to switch your
equipment on and o at the times you have nominated.
Your timer has a standard clock face and hands set in the clear centre section, whilst the outer
grey bezel shows the hours in military style (24 hour) time. To set the clock to present time, place
your nger on the clear centre bezel and slowly turn it clockwise to the desired time. Time of day
can be set by the clock hands or by lining up the outer grey numbers to the corresponding time of
day, which is set at the red indicator line.
At the end of each cell operational cycle (or cell reverse), the power on/no water ow
light & overload light (Fig. 1, Items 3 & 4) will ALTERNATE by ashing in a slow fashion
for approximately thirty (30) seconds. This is the cell rinse procedure and is part of the
normal operation, which occurs at each reverse cycle change of your CHROME™ REVERSE
POLARITY chlorinator. On completion normal operations in the next cycle will begin.
Contrary to popular belief, during both normal and reverse cycle modes the chlorinator
continues to manufacture chlorine, whilst at the same time the opposite polarity cell plates
are being automatically cleaned.

12
TIME CLOCK OPERATIONS (TIMER MODELS ONLY) ...continued
(FIG. 1, ITEM 7)
Start and stop times are set by pushing in the small grey time setting elements at the extreme
outside of the time clock face and exposing a red mark. Each element represents fteen minutes
and these should be positioned showing the red marks at the times you wish your lter plant and
chlorinator to operate.
With the elements pushed in and the red marks showing the timer will turn your equipment on
when they reach the red indicator line. With the elements pushed out and the red marks not
visible the timer will turn your equipment o at the end of the red.
The top left hand side of your time clock has provision for overriding the timer settings. With the
switch set in AUTO mode, the unit will switch at your designated times. With the switch set at
ON, the timer will by-pass timer settings and run continuously. Remember to put this switch back
to AUTO after using the by-pass function.
To turn the unit and pump o during its timer cycle you will have to turn it o at the power
point or isolation switch that your electrician may have tted. If you use this method and
interrupt power supply please remember to reset the time clock to present time when you
reconnect unit to power.
The top right corner of the timer has provision for setting the hertz (Hz) (this is a measurement
of electrical frequency) to either 50 or 60. This has been factory pre-set at 50 Hz (for
Australian conditions) and should not be moved. If it has been moved to 60 Hz your timer will
lose time and should be reset to 50 Hz.
SPECIAL NOTE ON TIMERS (TIMER MODELS ONLY):
If you require your CHROME salt water chlorinator to be connected to a cheaper o peak
tari we recommend the use of an appropriate quartz time clock for that purpose. The
unit may also be hard wired in however, in case of incorrect wiring or damage caused by
modications warranty will be void.
We suggest that an appropriate quartz time clock (with battery backup) be tted in
lieu of the standard model to allow time of day to be maintained when power supply is
interrupted.
Quartz time clocks can be tted at factory stage, or later at extra cost. Please see your
CHROME representative if you wish to have this done.
Quartz time clocks are discernable by their model A-TB72Q marked on the lower left
casing of the clock. In lieu of the 50 – 60 Hz switch, a power light is tted indicating power
to the timer and the chlorinator unit.

TIMER BY-PASS SWITCH (TIMER MODELS ONLY)
(FIG. 1, ITEM 8)
If your CHROME chlorinator has a timer by-pass switch tted you will nd this located on the
front panel on the right hand side of the time clock. This switch allows you to bypass timer
functions without the need to use the auto – on switch located in the timer frame. If this external
switch is tted to your CHROME unit, then the internal timer switch must remain in the AUTO
position and the timer by-pass functions are operated by utilising the external timer by-pass
switch. Three functions are available:
TIMER:
The time clock will automatically switch your pool equipment on or o at your designated times.
OFF:
The time clock will not switch, but normal time will be maintained.
BY-PASS:
The clock has by-passed all designated functions and will operate pool equipment indenitely.
PLEASE NOTE: Return switch to timer position after using the ‘o’ or ‘by-pass’ functions.
GENERAL CHLORINATOR OPERATION
Before switching on your CHROME salt water chlorination system please ensure that you have
added the correct amount of pool salt, it has fully dissolved and is distributed throughout the pool
water. (see Addition of Salt Section). Ensure that the base pool chemistry is at the recommended
levels and the pool water is clean and crystal clear.
Switch on the pool lter system and the CHROME unit. At this point the CHROME electronic
display may register a water ow fault as the cell housing lls with water and an alarm (beeping)
may activate. This is normal start up procedure and will cease as soon as the unit registers full and
correct water ow throughout the electrodes. (see Water Balance Section)
With the chlorine controller knob (Fig. 1, item 5) now turned fully clockwise to the maximum
position the green chlorine output indicator lights will illuminate one after the other. With the
correct amount of salt added to the pool water you should achieve a 100% (ten lights) reading. In
this position the CHROME chlorinator is producing maximum chlorine output.
As previously stated, chlorine demand will dier from pool to pool due to bather load, water
temperature or weather conditions and this must be taken into consideration. By testing for
chlorine residuals on a regular basis you will quickly determine the chlorine state of your pool and
what action you need to take to adjust it if required.
After determining your particular pool’s chlorine needs, you can set the controller to the desired
setting to achieve your chlorine requirements and/or adjust your daily running times. Normally
once set, these controls do not require further adjustment except perhaps for the seasonal ones
suggested earlier.

17
Set your chlorine controller to achieve maximum and optimum results for your pool situation.
Please remember that an over chlorinated pool is not a healthy pool, so it may not be necessary
for you to run your chlorinator at maximum output to maintain recommended chlorine levels.
Your CHROME salt water chlorinator is tted with a sophisticated electronic circuit board which
is designed to minimise the need for manual operations and maximise cell life by constantly
managing the correct operation of the power supply and electrolytic cells. In addition to the four
warning lights, a warning alarm (beeper) has been installed to alert you of any problems that the
electronic monitoring system has interpreted. The alarm will activate to alert you to any problems
that have been detected, and once rectied the unit will resume normal operations.
IMPORTANT NOTE
Your CHROME™ reverse polarity monitoring system is factory pre set to reverse cycle at
the completion of each 2 hours operational period. The circuitry is tted with a microchip
that measures the actual operating hours of the electrodes. When the chlorinator has
operated for the total factory designated hours in one direction it will then change
(reverse) cycle and operate in the opposite direction for the same operational time.
This ensures that the electrode plates (+ and -) each receive the same operational time,
therefore equalising and extending cell life, and ensuring adequate cleaning for each cycle.
By maintaining a watch on the indicator and warning lights, keeping the cells in a clean
state and chemically balancing your pool water regularly you are ensuring trouble free
operation of your CHROME™ chlorination unit with the least amount of eort.
CHLORINATOR RUNNING TIMES
Chlorinator running times will vary from pool to pool, and are dependent upon the situation they
are installed into, pool size and the overall usage of the pool in general.
Several factors will determine the operational time of the chlorinator to be able to produce
sucient chlorine for your pools requirements:
TIME:
The longer you run your lter plant and chlorinator, the more chlorine you will produce.
RATE:
The higher the chlorine output indicator lights up, the more chlorine is being produced.
CELL CLEANLINESS:
The cleaner the cell, the better the chlorine production rate.
BASIC POOL CHEMISTRY:
The more correctly maintained, the less chlorine waste.

18
CLEANING THE ELECTROLYTIC CELLS
From time to time it will become necessary to clean calcium and other deposits that will form on
the chlorinator electrolytic cell plates. Cleaning maintenance of the cells will vary from one pool
to the next depending on water conditions and calcium build up rate on the electrodes. Cleaning
times will also vary from model to model.
RP models are, to a large extent, self cleaning. However, it must be understood that proper
maintenance of the electrodes is essential for optimum chlorine production, and longevity of cell
life. We recommend that the chlorinator cells be cleaned on a regular and specied maintenance
and cleaning program.
This should always be done wearing the correct protective equipment.
Cleaning of the cells is a very easy task. First mix a solution of one (1) part HCL (pool acid) to
eight (8) parts of water. You should make sucient to be able to immerse the cell completely
but not the cell head or brass connectors. For safety please remember to add the pool acid to
the required amount of water, not the water to the acid. Ensure that your container is deep
enough to immerse the entire electrode plates within the solution.
Switch o the pool lter and chlorinator system, and isolate the power to the unit. Close any
shut-o valves that may be tted to your system and, after ensuring connectors are not hot
gently ease the cell leads from their terminal posts.
DO NOT TOUCH overheated connectors as burns to the ngers may result.
Turn the locking ring on the cell housing anti clockwise so that the electrode bundle can now be
removed from the cell housing. Immerse the cell plates into the pre mixed water/acid solution,
where a chemical reaction occurs, causing the liquid in the container to bubble. This is a normal
reaction as the calcium deposits are being cleaned from the electrode plates.
It should take approximately eight to ten minutes for this process to be completed and the cells
should then be cleansed of all deposits. If not, you may repeat the above step one more time, but
not more than twice in the one cleaning session.
DO NOT use any brushes, harsh scrubbing, chemical cleaners or attempt to scrape o the
deposits as this can damage the electrode special coating, reducing cell life, and voiding warranty.
After cleaning, rinse the electrode bundle in fresh water. Dry and clean the brass terminal
posts and bu them to remove all traces of dirt and build up. Please ensure that the terminals
(Black & Red) are rmly tightened before reinstalling your cell. Failure to do so may result in the
overheating of the cell connectors on both the cell cap and the lead causing damage to your cell
that is not covered by the warranty terms.
Replace the cell into its housing, remembering to ensure that the cell terminal post with the
red pole is uppermost. Tighten the cell locking ring by turning clockwise. Open any shut-o
valves that you previously closed and now connect the cell leads to their respective terminal
posts, remembering RED to RED pole, BLACK to BLACK pole, with the sensor lead to its special

19
position. You are now ready to resume lter and chlorination operations.
REMEMBER a clean electrolytic cell will extend the cell life as well as producing maximum
chlorine without the necessity of running the power supply at continually higher settings. By
keeping your cell in a clean state at all times you are eectively safe guarding your investment
and maximizing the cell life of your salt water chlorinator
SPECIAL NOTE ON CLEANING CELLS
Although you have a reverse cycle (Automatic Cell Cleaning) chlorinator, it is recommended
from time to time that the cell be checked for any accumulation of calcium or other
deposits that may have built up. During 8 hours reverse cycle a ne lm of calcium builds
up on the edges of the plates, but this should be automatically cleaned after every cycle.
In some areas, the chemical composition of the water can cause an excessive build-up of
calcium on the plates in a shorter period of time than usual. This condition will require
extra attention to ensure cleanliness of the cell. It is a good practice to check the cells
occasionally for excessive build-up, to ensure that the lead connections are clean and rmly
tightened, that the electrode spacers are in place and to remove any other foreign objects
that may have become trapped if necessary. We recommend cleaning the cell once or twice
a year subject to your pool’s application and location. To clean the electrode (cell), please
refer to “cleaning the electrolytic cells” section.

POWER SUPPLY INSTALLATION, REPAIR & MAINTENANCE
The installation of the chlorinator should be carried out in accordance with the local wiring rules.
The chlorinator power pack should be located in the correct pool zone and connected to supply via
a power outlet that is protected by a residual current device (RCD) having a rated residual operating
current not exceeding 30mA. The power outlet should have a degree of protection suitable for the
pool zone. Ensure that equipotential bonding of all parts of the pool installation is carried out.
INSTALLATION
Tools required before you begin
Before you begin installing your chlorine generator please check you have the right tools
and a suitable location. Please also ensure you have read and understood the specications,
requirements and wiring rules.
• A cordless drill (a power drill is ok).
• A 6mm hammer drill bit if you need to drill into brick or concrete.
• A pencil or marking pen.
• A saw for cutting PVC pipes. Glue and necessary pipe ttings.
• A philips head screwdriver or bit (for the drill).
• Power Supply must be installed on a straight length of horizontal pipe on the return line
(after all other accessories). The chlorine generator should be last.
• A power point needs to be located no more that 1.5M away from where you mount
the power pack.
• If attaching to a post, you must x a waterproof panel to the post rst,
measuring 350 x 350mm
• It is recommended to have Chlorinator away from direct eects of weather elements
and well ventilated
