How it works:
A salt or mineral chlorinator works by putting a dc current through an electrolytic cell in a
flow of salted water. Salt/minerals is made up of sodium/magnesium and chloride ions.
Electrolysis of these salts produces chlorine gas, which dissolves almost instantly to form
free chlorine in the water. This free chlorine is a highly effective sanitiser for your pool.
Your Pool Controls Chlorinator constantly adds a dose of chlorine to the water over the
operating period of the system. The amount of chlorine added depends upon the cell
output and the running time.
Generally, a salt water or mineral pool is run for around 8 hours per day in summer and 2
to 4 hours per day in winter. The summer operating periods are usually in the early
morning and later evening. This allows a chlorine residual to build up for pool use during
the day.
The filter system should always be running when the pool is being used. If a pool
cover/blanket is used the chlorine demand will be greatly reduced. To avoid over-
chlorination use the Pool Cover Mode On/Off button. See pages 4, 12 and 16.
pH Control
When chlorine is added to water the pH always changes –this is because chlorine is not a
neutral chemical. The pH will slowly rise as chlorine is produced in a salt/mineral water
system. A rise in pH greatly reduces the effectiveness of the chlorine as a sanitiser, so it
is important to ensure that the pH remains in the correct range.
The pH of the water can be lowered by the addition of acid –and if your chlorinatorhas the
optional pH control, this can be done automatically. Pool Controls’ pH Control System uses
a sophisticated algorithm to calculate how much chlorine has been produced by the cell,
and how much acid needs to be dosed to correct the resultant pH rise.
The algorithm can be adjusted if installed on a concrete/plaster pool. When adjustments
are made it should be in small values with the pool then monitored for effectiveness.
Note: while the algorithmic pH control is effective it does not measure pH.
pH measurement and checking must be done manually to make sure the pH is correct.

Page 4
Initial pool balance
Before you begin using the Chlorinator, make sure your pool water is balanced as follows:
Salt and Minerals –only add salt/minerals after checking the levels
For SG and SWC chlorinators there should be between 3000 and 5000ppm of TDS in the
pool ideally 4000ppm. This is achieved by adding 4kg of salt for every 1000 litres (1m3) of
pool volume. Note that this amount of salt will take time to dissolve.
Note: keep salt/minerals below 7500ppm to avoid overloading the cell and causing
shutdown. Only add after checking the level.
For XLS chlorinators there should be between 900 and 2000 ppm (ideally 1000ppm).
This is achieved by adding 1kg of salt for every 1000L
Minerals: the conductivity of minerals is different to pure salt. All TDS testers are
calibrated for sodium chloride salt. You will need less weight of minerals to achieve an
equivalent TDS to salt –follow the mineral instructions.
Chlorine
If it is a new installation, add enough chlorine (liquid or granular) to achieve a reading of
3ppm on an appropriate test kit.
Chlorine Demand and Pool Cover Blankets
Most of the chlorine demand for a pool comes from the action of sunlight on the chlorinated
water. When a cover blanket is used it is possible for the chlorine residual to build up to a
higher level that can be damaging to the blanket and possibly the pool and fittings.
This unit can adjust the output to compensate for the use of a cover blanket –simply push
the button and the display will flash COVER. While the cover is on the chlorine output will
be reduced. When the cover blanket is removed simply push the button again and the unit
will revert to its normal chlorine output. See also pages 12,16 and 20.
Stabiliser
If the pool is outdoors, it is vital that stabiliser (also known as cyanurate and cyanuric acid)
be added and maintained at 50ppm. This compound reduces chlorine destruction due to
sunlight. However, too much stabiliser will reduce the effectiveness of chlorine and can
result in poor quality water so ensure stabiliser does not exceed 80ppm.
pH
For chlorine to be effective, the pH must be within a certain range. This is usually between
6.8 (fibreglass/liner pools) or 7.2 (concrete/plaster) and 7.8. Adjust pH down with acid –
powder, liquid sulphuric or liquid hydrochloric. Be very careful with acid as it can be harmful
and corrosive.

Page 5
Minerals and pH: the magnesium in mineral salts can form a soft scale on the cell even
though it is reversing polarity. This is minimised by keeping the pH at the lower range for
your pool type. The use of hydrochloric acid is recommended for magnesium mineral
systems.
Total Alkalinity (TA)
Total alkalinity is also known as carbonate hardness or TA for short. The recommended
level is between 80 and 120ppm. TA is related to pH in that it stops the pH from varying
quickly with small additions of acidic or alkaline chemicals. When the TA is low it is almost
impossible to control the pH. To raise the TA, buffer (sodium bicarbonate) is added. This
must be done slowly as buffer will also cause the pH to rise. As an approximate rule every
increase of 20ppm of TA will also cause a 0.1 rise in pH. Once buffer is added it should be
left to mix in the pool for a few hours before reducing the pH.
Phosphates and Nitrates
Phosphate and ammonia nitrogen will make your garden green –and they will do the same
thing to your pool. Check for phosphates and add phosphate remover if necessary. Don’t
let fertiliser get into your pool! Phosphates are also in some cleaning products –check the
label if using around your pool.

Choosing a good location
Pool Controls chlorinators are manufactured from weather resistant materials and are
designed for operation in full sun and rain. However, your machinewill benefit if it is
protected from the weather.
Choose a well-ventilated area to allow for efficient cooling. Installing the unit in a hot and
closed shed or box may lead to overheating and activate the internal protective thermal
cut-out.
The Power Supply should not be mounted in areas where chemicals are stored (eg acid
and chlorine) as vapours from these chemicals are corrosive and may damage the
electronic controls within the unit.
Insect intrusion (particularly ants) can cause problems with all equipment. Ensure that the
pool equipment area is kept free of insects as much as possible. Insect intrusion is not
covered under the warranty.
Installing the Power Supply
Locate the Power Supply close to the Cell/Housing and filtration pump so that both may be
connected easily.
Mount the Power Supply at least 1.5m above the ground and at least 3m from the pool
water.
Connect Power Supply to the mains power outlet of the pool area and make sure this outlet
meets all applicable Australian Standard at the time of installation.
The PUMP socket outlet in the base of the Power Supply is dedicated to the filtration pump
only. Do not use a double adaptor to connect another pump as this will overload the
system and void warranty.
Installing the Cell
The cell housing assembly should be plumbed into the pool return line after all other
accessories (and prior to any heating take-offs).
Remember that the cell will need to be removed from its housing periodically for cleaning –
do not place it where its removal will be obstructed.
Note any water flow direction on the cell housing and ensure the cell housing is installed so
that water will flow in this direction.
Connect the Cell to the cable from the Power Supply. Ensure that all 3 connections (2 for
cell power and 1 for gas sensing) pushed on all the way. It is important that the connectors
are kept clean and dry. The black cable goes to the top-left power connection, the red
cable to the gas sensor bolt and the blue cable to the bottom-right power connection. See
photo on the next page.

SWC Cell Cable Connection
Installing the pH Control System
Units with pH control have an injection fitting and a peristaltic pump which must be
installed. Refer to the installation diagram on the next page for details.
Position the dosing pump as indicated in the installation diagram, ensuring it is NOT too
close to other equipment or power outlets (due to corrosive fumes from the acid). Attach
the dosing pump to the wall and connect it to the power supply where indicated in the
photograph below.
Fit the injection point, avoiding high pressure areas (ie not between pump and filter). It can
go prior to the cell if necessary.
Cut a length of tubing that will reach from the base of the peristaltic pump to the injection
fitting. Connect one end of the tubing to the outlet side of the peristaltic pump (the
direction of flow is indicated by an arrow on the front cover of the pump.) Connect the
other end of the tube to the injection point.
Cut another length of tubing that will reach from the base of the peristaltic pump to the
base of the acid drum. Position the acid drum in a safe and secure location, preferably
about 2 metres from the Power Supply Unit
Connect the one end of this tube to the inlet side of the peristaltic pump (the direction of
flow is indicated by an arrow on the front cover of the peristaltic pump.)
Drill an 8mm hole in the lid of the acid drum and pass the tubing through the hole in the
drum lid. Place a sinker on to the end of the tubing that will be in the drum and then attach
the drum filter. Note that the drum filter incorporates a non-return valve to prevent back-
flow into the chemical drum. Lower the drum filter and sinker into the drum and screw on
the lid.

Turn on the Power Supply, which will recognise that a pH Control System has been
connected and when first installed the LCD will ask “dilute acid?” If full strength is to be
used press “N”. If you are using diluted acid then press “Y”. (See page 17 and also
Advanced Menu Settings Supplementary Manual for details of the Acid Dilution Menu)

Front Panel
Display
A two-line LCD display is used to provide the user with information.
The first line of the display shows the current time and the cell status and output.
In the example above the time is 10.15am and the Cell is “OFF”. If the Cell is on, the
output of the Cell will be displayed. If the output of the Cell has been set at lower than
100%, “CELL OFF” will be displayed intermittently even while the unit is running as the Cell
regulates output. (See Chlorine Output Menu on page 16 for more details)
The second line of the display shows the automatic timer status.
In the example above, the automatic timer status is “OFF” and the display is telling you that
the chlorinatorwill turn on again at 17:00 or 5pm.
Note that the time is displayed using a 24-hour clock.
Operational Buttons
There are 5 buttons that allow you to control the various functions available via the Menu
system.
ON Button
Turn the System On Manually: Press the ON button once to switch the chlorinatorand the

Select this option by pressing ENT and the LCD will show the start (ON) time of the filter
cycle being adjusted. Use the Y/UP and N/DOWN buttons to adjust the start time. Press
ENT to confirm your selection and then the LCD will show the end (OFF) time for that filter
cycle. Adjust the OFF time in the same way as the ON time and press ENT to confirm.
After ON and OFF times for the first filter cycle have been adjusted, the ON time for the
second filter cycle is shown on the LCD. This can be adjusted in the same way, or if you
do not wish to make any changes, simply press ENT to confirm the time shown on the
LCD. Follow the same process to either adjust or confirm the OFF time for the second
filter cycle, and once this has been confirmed the LCD will display the home screen.
Note: an additional 2 filter cycles can be enabled and programmed via the Advance
Settings Menu –see Advanced Settings Supplementary User Manual, which can be
downloaded from poolcontrols.com.au.
Running Times
We recommend your system be operated for at least 8 hours per day and always run
the system when using the pool.
The amount of chlorine being added to the pool each day is determined by the cell size,
the chlorine output settings (See Chlorine Output Menu below) and the number of hours
that the system is operated. As sunlight destroys chlorine, it is recommended that the
system be run mostly in the evening.
Chlorine is added for sanitation but the filter is needed to remove pollutant particles (dust,
sand etc) and keep the water looking good. The filter must operate for a reasonable
number of hours per day to remove pollutants.
In very hot weather and/or with large bather loads, the pool may need to run for even
longer and if necessary, extra chlorine should also be added manually. If there are
adverse local conditions –such as windborne dust and debris - the chlorine demand will be
higher than normal and you will likely need to operate the system for longer periods to
adequately filter the water.

Controlling the Chlorine Residual
There are two ways of controlling the amount of chlorine entering the pool –by altering the
running times and by reducing the chlorine output. If the pool chlorine residual tests high
you can reduce the operating time and/or decrease the output. If the chlorine residual tests
low and the output is already at maximum you will need to increase the operating time
and/or add supplementary chlorine.
Output Control
The LCD display usually shows the amount of chlorine being produced by the Cell as a
percentage of its maximum.
However, this is the not the same as the Output. The Output Control turns the Cell
ON/OFF over a short period of time. The Output setting determines how long the ON time
is –for example if the Output setting is 60% the Cell will be ON for 60% of the period and
OFF for 40% of the period. This is why the Cell will turn ON/OFF periodically if the Output
is set below 100%.
Chlorine Output Menu
To adjust the chlorine output on your system, press ENT to access the Menu system.
Scroll down using the N/DOWN button until CHLORINE OUTPUT is displayed. Press ENT
again to select this menu and then used the Y/UP and N/DOWN buttons to adjust the
output level. Confirm the adjusted settings by pressing ENT once more.
Superchlorination
When bathers enter a pool there is a reaction between nitrogen/ammonia compounds from
the bathers and the chlorine in the pool. These reactions form chloramines (also called
combined chlorine) which are responsible for the “chlorine” odour and for some minor
irritations.
These compounds can be broken down by adding free chlorine to a level above 5ppm by
the addition of a shock dose of chlorine –also known as superchlorination.
Levels of chlorine immediately adjacent to the cell anodes far exceed 5ppm and so a lot of
chloramines are destroyed as water passes the cell.
If the chloramine levels still become high, simply add a shock dose of chlorine or run the
chlorinator for a long period overnight.
Pool Cover Mode On/Off –when chlorine demand is reduced
To adjust the chlorine output to compensate for the use of a cover blanket the unit must be
made aware that a cover blanket is in place over the pool. simply push the button marked
“Pool Cover Mode On/Off” for on and off selection. When the Pool Cover Mode is
activated, the word COVER will flash in the display and the chlorine output will be reduced.

Page
16
Navigating the +Acid Menu
As chlorine is produced the pool pH will go up slowly. This can be offset by small doses of
acid added to the pool. An algorithm calculates the amount of acid per dose that is needed
to maintain the pH, and once the system has been adjusted to suit your pool, maintenance
should be minimal. Note that the pH must be adjusted correctly for the controller to
maintain it.
However, it is vital that the system is initially adjusted to suit your pool
and that pool pH is checked regularly.
Accessing the +ACID Menu
It is only possible to access the +ACID MENU when a dosing device is attached. Press
ENT to access the Menu system and use the Y/UP or N/DOWN buttons to scroll through
the menu until the LCD Line1 reads “hh:mm +ACID MENU” – press ENT to select.
Acid Dosing System –Turning it ON and OFF
The default setting is for the acid dosing system to be ON.
To turn the Acid Dosing System OFF, access the +ACID MENU as described above and
Line 2 of the LCD will read “ADJUST Man DOSE?”. Press the N/DOWN button to answer
“no”.
The LCD will now show “ADJUST AutoDOSE?” Press N/DOWN to answer “no” and the
LCD will ask “DOSER OFF? Y/N”. Press Y/UP if you wish to turn the Acid Dosing System
off.
To turn the Acid Dosing System back on, access the +ACID MENU as described above
and Line2 of the LCD will read “DOSER ON? Y/N”. Press Y/UP to answer “yes” and the
Acid Dosing System will be enabled.
Adding Acid Manually –the ADJUST Man DOSE Sub-Menu
When you first ENTer the Acid Dosing System, the LCD will ask “ADJUST Man DOSE?”
This sub-menu allows you to adjust the amount of acid added as a manual (immediate)
dose. Adjustment is from 0mL (OFF) to 750mL in 15mL increments. This function is
useful for priming acid lines after an acid drum change, and for adding a large dose of acid
after adding buffer.
If you wish to make a manual dose, or adjust settings, press Y/UP to access this sub-
menu.
Line1 of the LCD will display: “hh:mm Man DOSE”;
Line2 of the LCD will display: xxx mL”
Use the Y/UP and/or the N/DOWN buttons to adjust the amount of acid to be dosed
manually. Press ENT to confirm and return to the Home Screen. Dosing should begin in
approximately 5 seconds.

Page
17
Automatically Dose Acid –the ADJUST AutoDOSE Sub-
MENU
Note: fibreglass and liner pools are unlikely to need to need adjustment of
auto dose amounts.
This sub-menu allows you to adjust the amount of acid added as an
automatic dose. Adjustment of the DOSE# is in increments of 10.
PressY/UP when Line 2 of the LCD asks “ADJUST Auto DOSE?” to enter
this sub-menu.
Line1 of the LCD will display: “hh:mm Auto DOSE”
Line2 of the LCD will display: “<90> 90 DOSE#” (note that <nn>
denotes the default value)
Use the Y/UP and/or the N/DOWN buttons to adjust the amount of acid to
be dosed automatically. The value will be used by the algorithm to
determine how much acid and when to add it automatically.
Press ENT to confirm and return to the Home Screen and normal operation.
Priming the Dosing Pump
To prime the acid feed line –go to the +ACID Menu and do a manual feed
of 100mL (or more if necessary due to length of feed tube). Note: the
dosing pump will only start after the filtration system has been running for 2
minutes’ “start delay”. Once the dosing pump is running, double check the
pump rotor direction and ensure it is correct (otherwise water will be
pumped into the acid drum.)
Adjusting the pH Control for Dilute Acid (Advanced Settings Menu)
If a unit has been installed with the pH Control Dose Pump this setting has likely already
been made by the installer.
To enter the Advanced Settings Menu hold the OFF-button down for approximately 4
seconds and when Advanced appears in the display press ENTer. Use Y/UP or N/DOWN
buttons to scroll through the menu until LCD Line2 shows “ACID Dilution” and press
ENTer. The LCD will show:
“Dilution NO”
“Dilution Y/N?” Press Y/UP for dilute acid use.
There are three possible dilution rates to select from using the Y/UP and N/DOWN buttons:
“Acid approx 10%” “Acid approx 14 - 16%” “Acid approx 20%”
“1 Acid : 2 WATER” “1 Acid : 1 WATER” “2 Acid : 1 WATER”
Note that undilute acid is generally 28 –32%. Note also that dose pump run times are
longer when dilute acid is used.
