!
IMPORTANT!
Your appliance must be installed by a qualified and experienced pool
professional.
3.1/ Prepare the swimming pool
!
IMPORTANT:
the TRi PRO module is designed to automatically ‘MAINTAIN’ the chlorine
level (ACL) and pH in your pool.
However, it is mandatory to control and adjust water balance parameters
before installing this unit. This will help you keeping a correct water balance
during the season.
Remark: See chapter 7 / ‘Water balance’ to know how to adjust water
parameters before installing TRi PRO module.
3.2/ Installing TRi PRO module
1. Switch off the Zodiac TRi salt water chlorinator by pressing the
button.
(1)
2. Switch off the filtration system by cutting off mains supply into
filtration’s electric enclosure.
3. Close the valves cutting off the pipework.
4. Remove the silver cover cap (1).
(2)
5. Remove screws holding the original lower module (empty) on the main
TRi unit. (2 screws on sides and 2 screws on the bottom) (2).
6. Remove the empty original module and replace it with your new TRi PRO
module. Connect the TRi PRO module ribbon cable (flat cable with black
male connector) to the corresponding black female connector of the TRi
power pack (3).
7. Position the TRi PRO module correctly and tighten the 4 screws. Put the
silver cover cap back into place.

!
25
IMPORTANT: Do not connect the unit to mains supply before the TRi
PRO module, the POD holding sensors and its pH minus injector pipe are
installed (see chapter 3.8 / ‘Testing / Priming the peristaltic pump’).
3.3/ Installing the POD
The TRi PRO POD integrates in a single sub-assembly all the necessary
elements. That means flow switch (used by your TRi salt water chlorinator), pH
sensor, ACL sensor and pH minus one-way valve.
Figure illustrating the location of TRi PRO complete system
➤ WARNING : the TRi cell bypass valves must always be fully opened.
!
IMPORTANT RECOMMENDATIONS:
- TRi PRO POD must always be installed onto a horizontal pipe to be sure
that pH & ACL sensor will be positioned vertically.
- POD must be the first element installed just after the filter.
- If pool is heated (heat pump, heat exchanger, electric heater…), POD will
be positioned before heating system (reading made with non heated
water).
- It is recommended to place the POD at least 20 cm from a bend in the
pipe.
- pH & ACL sensor cables must not be close to high voltage cables to
prevent false readings.
NOTE: An incorrectly installed pH and/or ACL sensor may give erroneous
measures resulting in inappropriate operation of your TRi equipment. Neither
the manufacturer nor the appliance will be held responsible in this case.
1. Choose a straight pipe section with appropriate length after filtration (30
cm minimum, without bend).
(1)
2. Disassemble POD sub-assembly (part #10) to keep the bottom part of POD
clamp (with 2 holes) (1).
3. Put the bottom part of POD clamp upside down onto dedicated piping place.
Use a marker or a centre punch to indicate the location of the 2 holes to be
made in the pipe (2).

(1)
- pH sensor (blue, part #2) is designed for reading the pH of pool’s
water.
- ACL sensor (red, part #3) is made for reading Redox potential
(ORP) of pool’s water to automatically adjust chlorine generation
(« Active Chlorine Level ») of TRi salt water chlorinator.
➤ Follow instructions hereafter for both pH & ACL sensors.
1. Carefully remove the small protection bottle that contains a preservative
liquid by unscrewing its cap. (1).
!
(2)
2. Rinse the end of sensor with clear tap water, then shake off any excess of
water.
WARNING: Never wipe sensors with a cloth or a piece of paper as this
could damage it!
3. Set the 2 bottles containing the preservative liquid aside for long term and
wintering storage. Empty the preservative liquid solution, filling it with tap
water will be sufficient when storing pH & ACL sensors.
4. Introduce pH & ACL sensors (parts #2 & #3) into their respective sensor
holders and tighten locking rings by hand. Ensure that sensors are not
inserted too far into their housing (see following picture with red dotted line
which indicates the driving in limit) (2).
27
5. Now sensors could be connected to TRi control box unit. pH & ACL sensors
must then be calibrated before using TRi PRO module (see chapter 4 /
‘Calibrating pH & ACL sensors’).

Calibrating pH & ACL sensors
!
IMPORTANT: In order to operate accurately and reliably, it is essential for
pH and ACL sensors to be calibrated before operating the TRi salt water
chlorinator with the TRi PRO module.
To do this, check that the TRi power pack is connected to the mains supply,
turn off the pool pump and isolate pH & ACL sensors by closing the valves so
as to remove sensors from the POD safely.
4.1/ pH sensor calibrating procedure
1. Remove the pH sensor (blue) from its holder onto the POD (manually
unscrew the tightening collar). Rinse the extremity of the pH sensor with
clear water and shake it so as to remove any excess water. Do not touch or
use a cloth to wipe the glass bulb on the extremity of the pH sensor! (1).
(1)
2. Place the pH sensor in a sample of ‘pH 7,5’ blue buffer solution (provided,
see picture below).
3. Leave the pH sensor immersed in the buffer solution for approximately 5
minutes in order to ensure a reliable measurement. (2).
4. From the default display on the LCD screen, press the
button.
5. Use the
buttons to display pH/ACL SETUP, then press
6. Use the
buttons to display CALIBRATE pH, then press

10. Press
button twice or wait 30 seconds, the
TRi power pack will return to the default display
on the LCD screen.
IMPORTANT NOTES:
- In order to ensure that the Zodiac TRi remains fully efficient it is
recommended to perform a calibration at least once every two months
during the season of pool use.
- Ensure that the pH sensor is perfectly clean before starting a calibration
operation (Refer to chapter 8 / ‘pH & ACL sensors cleaning’). Then rinse it
with clear water, this will ensure that the calibration will be more accurate.
4.2/ pH set point
The pH set point is the value to which the Zodiac TRi will adjust the pH in the swimming
pool water. This value is always displayed on the LCD screen. The default setting for
the TRi PRO module is 7,2 pH. This value corresponds to the ideal compromise so as
to achieve optimal efficiency in terms of water disinfection, but it can be changed to
adapt to specific pool conditions and requirements.

4.3/ Setting the pool size
To ensure that the pH is regulated under the best conditions for your pool,
it is necessary to adapt the settings of the peristaltic pump according to the
volume of water in your pool so as to release only the required quantity of pH
minus (dosing cycle adjustment). This setting is performed only once when
activating the TRi PRO module for the first time, it is not necessary to change
it thereafter.
It is possible to set 4 different levels corresponding to 4 sizes of swimming
pool. List of sizes and corresponding volumes of pool water:
- Size #1 : For small pools up to 60 m3
- Size #2 : For mid-size pools between 60 and 90 m3
- Size #3 : For large pools between 90 and 120 m3
- Size #4 : For very large pools more than 120 m3
The above values are only indications, the exact values may vary according
to the conditions of use. However, it is recommended not to “over-size” the
setting so as to avoid using too much pH minus.
NOTE: For safety reasons, default pool size setting is #1 (lowest level).

operation (Refer to chapter 8 / ‘pH & ACL sensors cleaning’). Then rinse it
with clear water, this will ensure that the calibration will be more accurate.
4.5/ ACL set point
TRi PRO ACL function (« Active Chlorine Level ») made for automatically
‘maintain’ chlorine level to get a good pool’s water disinfection. TRi PRO
module continuously measures the ORP level to control TRi salt water
chlorinator operation.
!
IMPORTANT REMARKS:
> the ACL set point displayed on the LCD screen does not correspond to
free chlorine level into pool’s water ! It is only the selected level of ‘water’s
disinfection potential’ (ACL).
> The ACL set point required in order to obtain the optimal free chlorine
level is different for each pool. A regular manual chlorine level analysis will
be necessary to correctly adjust the ACL set point.
TRi PRO module has 6 different ACL set points (corresponding to 6 different
ORP levels).
The higher the ACL set point is, the higher the requested “disinfectant action”
will be, as a result the free chlorine level will be potentially higher, and vice
versa.
 To increase potential chlorine generation: increase ACL set point
 To decrease potential chlorine generation: decrease ACL set point
TRi PRO module default ACL set point is #1. (*)
(*) : Default ACL set point could be different depending on your unit software version.
!
IMPORTANT NOTE: It is recommended to set the ACL set point to #3
or #4 during the first few days after having installed the TRi PRO module
in order to quickly stabilise the free chlorine level (see chapter 7 / ‘Water
balance’). If the free chlorine level is correct after this start-up period, it will
be necessary to adjust the ACL set point accordingly.
To change the ACL set point:
1. Ensure that the ACL sensor has been calibrated (see above procedure).

Using Zodiac TRI with TRi PRO module
The Zodiac TRi is now ready to automatically regulate the pH and the ACL
levels in the pool water using the TRi PRO module.
1. Set the ‘ON’ and ‘OFF’ times (refer to the Zodiac TRi Salt chlorinator user
manual).
2. If the pool water pH exceeds the set point, the symbol ^ will be displayed to
the right of the pH set point value on the LCD screen. pH minus will then be
released automatically according to the predefined cycles.
If the pool water ACL is unsuitable to keep a good disinfectant effect (ORP
too low), the symbol ^ will be displayed to the right of the ACL set point
value on the LCD screen. Chlorine generation will automatically start
according to the predefined cycles.
3. Refer to the instructions concerning water balance hereunder in order to
ensure optimal operating conditions for the Zodiac TRi.
 Zodiac TRi Salt chlorinator together with the TRi PRO module will now
automatically maintain the appropriate pH and ACL levels for the pool water.
NOTE: The TRi PRO module is designed to use only pH minus (therefore to
lower the pH). Do NOT use other types of chemicals.

7
Water balance
The Zodiac TRI with the TRi PRO module is designed to disinfect the swimming
pool water via its controlled salt electrolysis function and to maintain the pH
level.
The following information concerning the values to be respected for a correct
water balance is essential in order to fully enjoy your pool.
Ensuring that the pool water balance is correct from the start will reduce the
probability of encountering problems during the first days of operation or
during the season of use of your pool.

pH & ACL sensors cleaning
To ensure that the TRi PRO module will operate under optimal conditions, it is
recommended to clean sensors (ph and/or ACL) before each calibration.
To clean a sensor:
- If the extremity of the sensor is covered with a greasy film (cosmetics
deposit, sun lotion….), place it for a few minutes in tepid soapy water. Do NOT
use detergent products but rather a liquid dishwashing product. Then rinse
profusely using clear water.
- If the extremity of the sensor is covered with calcium buildup or if the above
procedure was not sufficient, place the sensor in a 10% hydrochloric acid
solution for a few minutes (wear all necessary protective clothing).Then rinse
profusely using clear water.
Remark: It is possible to buy this acid cleaning solution from your local
swimming pool retailer. Then rinse profusely the pH tester with clear
water and proceed with the calibration before using it.
!
IMPORTANT:
- Always clean pH & ACL sensors before performing a calibration.
- NEVER WIPE THE SENSORS WITH A CLOTH but shake it gently in order to
remove any excess rinse water.

TRi PRO module maintenance and winterizing
Using the TRi PRO module allows for more freedom when monitoring the
pool parameters. However, it is necessary to check a number of settings on a
regular basis so as to ensure a correct and safe operation of the system.
NOTE: Your TRi PRO module uses a peristaltic pump that is designed
to release only pH minus. Do NOT use hydrochloric acid, pH plus or any
other chemicals.
TRi PRO module winterizing:
- When you want to winterize your TRi PRO module at the end of the season,
it is recommended to let it pump clear water instead of the pH minus so as to
rinse out the peristaltic pipe.
This pipe can be simply cleaned by using the peristaltic pump Testing and
Priming function (see chapter 3.8 / ‘Testing / Priming the peristaltic pump’).
- Remove the pH & ACL sensors from their respective holders. Store sensors
in their original bottle or in a bottle of water filled with tap water. Seal sensor
holders if necessary.
!
VERY IMPORTANT: NEVER let a sensor dry out, this would damage it
permanently.

Error codes and warnings
10.1/ PH LOW
 Meaning:
Pool water pH is 0,4 pH lower than the set point displayed on the LCD screen.
pH value should be manually checked before proceeding.
 Possible causes:
pH sensor needs to be cleaned and calibrated.
pH sensor is worn out and/or faulty.
This could also mean that the selected set point is too high or that the
selected pool size is too high.
 Solutions:
- Clean then calibrate the pH sensor (see chapter 8 / ‘pH & ACL sensors
cleaning’ and 4.1 / ‘pH sensor calibrating procedure’).
- Replace the pH 7,5 buffer solution, then calibrate the pH sensor.
- Check the selected value for pH set point.
- Check the pool size setting (see chapter 4.3 / ‘Setting the pool size’).
- If necessary, replace the pH sensor.
10.2/ PH HIGH
 Meaning:
Pool water pH is 0,4 pH higher than the set point displayed on the LCD screen.
pH value should be manually checked before proceeding.
 Possible causes:

- Clean then calibrate the pH sensor (see chapter 8 / ‘pH & ACL sensors
cleaning’ and 4.1 / ‘pH sensor calibrating procedure’).
- Replace the pH 7,5 buffer solution, then calibrate the pH sensor.
- Check the selected value for pH set point.
- Check the pool size setting (see chapter 4.3 / ‘Setting the pool size’).
- If necessary, replace the pH sensor.
10.3/ PH ERROR
 Meaning:
- The peristaltic pump of the TRi PRO module has operated for full dosage
cycles without achieving the defined set point (displayed on the LCD screen).
- The peristaltic pump of the TRi PRO module has not operated since more
than 72 hours.
 Possible causes:
The pH minus container is empty.
pH sensor needs to be cleaned and calibrated.
pH sensor is faulty.
Selected pool size setting is too low
The peristaltic pump is defused.
 Solutions:
- Replace the pH minus container if it is empty.
- Clean, then calibrate the pH sensor (see chapter 8 / ‘pH & ACL sensors
cleaning’ and 4.1 / ‘pH sensor calibrating procedure’).
- Check the pool size setting (see chapter 4.3 / ‘Setting the pool size’).
- Check the peristaltic pump operation (see chapter 3.8 / ‘Testing / Priming
the peristaltic pump’).
 Hold the
button for 3 seconds to erase an error code (when it blinks).
10.4/ ACL LOW
 Meaning:
Water disinfectant poser is too low (ACL). Free chlorine level into pool’s water
is probably too low. A manual free chlorine analysis should be done before
proceeding.
 Possible causes:
Water pH is too high.
Total alkalinity (TAC) is too low, which means an unstable pH.
ACL set point is too low.
A high bather load has generated a high chlorine demand.
ACL sensor needs to be cleaned and calibrated.
ACL sensor is faulty.
 Solutions:
- Manually check the pH value to be sure that pH regulation operates
correctly.
- Check total alkalinity (TAC) and adjust it if necessary (see chapter 7 / ‘Water
balance’).
- Increase the ACL set point (see chapter 4.5 / ‘ACL set point ‘).
- Clean, then calibrate the ACL sensor (see chapter 8 / ‘pH & ACL sensors
cleaning’ and 4.1 / ‘pH sensor calibrating procedure’).
- Replace the ORP 700 mV buffer solution, then calibrate the ACL sensor.
- If necessary, replace the ACL sensor.
38
10.5/ ACL HIGH
 Meaning:
Water disinfectant poser is too high (ACL). Free chlorine level into pool’s water
is probably too high. A manual free chlorine analysis should be done before
proceeding.
 Possible causes:
Water pH is too low.
Total alkalinity (TAC) is too low, which means an unstable pH.
