INSTALLATION GUIDE
The following steps will help you get up and running with your new Zodiac
TRi Chlorine generator.
POSITIONING THE POWER PACK
1. Locate a suitable space for the power pack bracket. It should be
installed no further than 1.8 meters away from the cell - ideally in a
filtration shed or close to the filtration equipment.
PLEASE NOTE: if fixing to a post it must have a waterproof panel fitted (behind the unit),
at least 450mm wide and 470 mm high.
2. Using screws provided, fasten the bracket securely to the wall and
position the power pack on the bracket. Plug into power point, but
don’t turn on the power.
POSITIONING THE CHLORINE GENERATING CELL
PLEASE NOTE:The cell should always be the last device placed on the water pipe
(In the return line to the pool).
3. Ensure the cell is placed horizontally, with the Inlet pipe connecting to
the fitting closest to the cell lead.
4. Using screw barrel fittings (supplied), attach the cell to the pipe. If using
40mm pipe, you will need to fit the cell using the reducing bushes (also
supplied).
5. When connecting the lead from the power pack to the cell match up
the corresponding colours and pins, then fit the end cap.
(Note: Either RED wire can be connected to either RED pin on the electrode.)
6. Plug your pool pump into the outlet socket in the bottom of the TRi
(this will allow the TRi timer to control the filtration times)
7. Once all connections are together press the mains power switch to ON.

5
USING INBUILT CLOCK AND TIMERS
When it comes to chlorination, every pool is different.To get what’s right
for you, you will need to set the unit’s clock and timers.
SETTING THE CLOCK
1. Switch power on.
2. Wait for the start-up sequence to complete.
3. Press the button to enter the MAIN MENU.
4. Use / buttons and scroll to SET CLOCK.
5. Press .
6. Use / buttons to set the hours.
7. Press to save the hours.
8. Use the / buttons to set the minutes.
9. Press to save the minutes.
TRi will then return to the MAIN MENU.
10. Press to return to the operating screen.
NOTE:The time is displayed in 24 Hour format

TURNING CHLORINE GENERATION ON
The chlorine generation of the TRi can be controlled in a number of ways:
1. Manually set to an output level, with the operating times determined by
an external timer.
2. Using the in-built timers on the TRi unit (refer to ‘The Timers’)
3. Using a connection to an external ‘third-party’ controller
(refer to ‘Connecting to a controller’).
To turn the chlorine generation on manually, press the ON/OFF button.
The output level can be set as described in ‘Setting the Chlorine Output.’
NOTE: For safety reasons, the TRi chlorine generator will continually dose chlorine for a maximum of
30 hours if left running with no ‘OFF’ time – unless connected to en external controller. After this time
the TRi will switch to ‘OFF’.
THE TIMERS
The Zodiac TRi chlorine generator comes with two inbuilt timers that
switch the filtration and chlorination system on and off as required.
During swimming season, consider running the system for around 8 hours
a day.This can be increased to 10 hours during periods of very hot weather.
In winter, it may only be necessary to run your pool’s filtration system for
4 hours a day. These shorter periods of activity will lengthen the life of the
unit’s electrode.
For best year round results, set the unit to operate during the cooler hours
of the early morning, evening or when swimmers are using the pool.
PROGRAMMING THE TIMERS
To activate the timer, you will need to enter both an ON and OFF time.
If no OFF time is entered, the chlorine generator will switch off at the
default time of 12:00am (0:00).
You will know that a valid time has been entered when a “T” Symbol is
displayed in the top right hand corner of the LCD display when the unit is
displaying the ‘operating screen’.

TESTING THE WIRING CONNECTION
Once a connection has been made between the Controller and the
Chlorine generator, it will need to be tested.
1. Turn on the power to the Controller and the Zodiac TRi.
2. If successful, a ‘ ’ symbol will appear in the top right hand corner of the
screen after about 20 seconds.
3. If the controller does not connect, turn power off to both the devices
and try again.
VERIFY THE WIRING CONNECTIONS
To verify the connection:
1. Switch the TRi unit on and check the controller setting (follow
instructions under ‘SETTING CONTROLLER’.
2. Re-test the connection.
Note: For safety reasons, the Zodiac TRi reverts to the OFF setting if the communication
connection is lost.
CONNECTION TO CONTROLLER FOR POOL/SPA
COMBINATIONS
To connect a Zodiac TRi unit to Pool or SpaValves, you will need to make
a “splice” into the control lines from the Controller, located inside the
controller itself.
For further information, consult the installation manual of the Controller
being used.

If your pool has a cover, you should set the output
level to “low”.This is also known as “winter” mode.
Reducing your chlorine output will help prevent
damage to your pool’s cover and other equipment.
MANUAL SETTING
1. To select Low mode press .
This will drop the chlorine output to around 10%.
2. ‘Low’ will appear on the screen.
Note: Low orWinter mode cannot be selected when TRi is being
controlled by an external controller.
AUTOMATIC SETTING
The Zodiac TRi can be connected to the valves of an automatic pool/spa
system.
When the input from the valves is set to ‘Low’ the TRi will automatically
revert to ‘Low’ mode and the output will be locked at 10%
Details of the wiring connection are outlined in the ‘‘Connection to Automatic
Pool/Spa Valve” section of this manual.
For users who have upgraded to the TRi-pH or TRi-PRO, the
automatic pH/ACL control function is disabled when in LOW
mode.
SETTING THE MODE TO LOW: IMPORTANT IF USING A POOL COVER

16
At times your pool may require a larger than normal application of
chlorine.The Boost function is used to rapidly add chlorine.
In BOOST or “Superchlorinate” mode, output settings are temporarily
overridden and the chlorine generator runs for 24 hours at 100% Chlorine
Production.
In ‘TIMER’ mode, the circulation pump will run for 24 hours, before
automatically reverting to previous output / timer settings.
In ‘MANUAL’ mode, the chlorine generator will run at 100% for a
cumulative total of 24 hours before reverting to the previous
output setting.
NOTE:
The ‘BOOST’ mode cannot be engaged under the following
curcumstances:
1) If the TRi is in the ‘OFF’ operating mode.The chlorinator must be
‘ON’ for BOOST to be engaged.
2) If you have upgraded to theTRi-PRO
3) Or from the front panel when the TRi is being controlled by an
external controller.

HELP AND TROUBLESHOOTING

18
To keep your TRi Unit in the best possible condition it is recommended
regular maintenance should be performed.
INSPECTING AND CLEANING THE ELECTRODE
In areas that experience calcium hardness the TRi electrode will benefit
from cleaning.
To clean your electrode:
1. Switch off the filter pump and chlorine generator, close necessary valves
and unplug the cell terminal cap.
2. Unscrew the retaining ring and
remove the electrode. If calcium
buildup is present, immerse the
electrode in cell cleaning solution
without immersing the terminals.
3. If you do not use commercial
cleaning solution, you can mix your
own by carefully adding one (1)
part of Hydrochloric (Muriatic) acid
to ten (10) parts water. Stronger
solutions will shorten terminal life.
4. Allow the cleaning solution to dissolve the calcium deposits for about
10 minutes. Dispose of the cleaning solution at an approved Council
Depot and never into storm water or sewage drains.
6. Rinse the electrode in clean water and re-fit the electrode in the cell
housing.
7. Replace the cell head and plug
assembly and reset valves and
switches.Turn pump and TRi on.
8. Confirm chlorine output and
settings on the power pack.Timer
settings will be automatically
retained.
