3.7/ Automatic detection (« Plug & Play » TRi PRO module)
Zodiac TRi power pack will automatically detect the presence of a TRi PRO
module. It will display 2 additional lines on the LCD screen, mentioning
pH/ ACL CONTROL and pH & ACL set points.
1. After startup, pH/ACL CONTROL will be displayed on the 3rd line on the LCD
screen.
2. pH & ACL set points will be displayed on the 4th line of the LCD screen (pH
at the left and ACL at the right). In addition, a ^ symbol is displayed at the
right of each set point value when measured value by the appliance needs to
be automatically corrected.
REMARKS:
1) pH regulation (peristaltic pump) is not activated as default setting
and the LCD screen will display as follows pH ---. Activation will take place
automatically approximately 8 hours after it is turned on. To manually
activate the pH regulation and display the set point on the LCD screen, refer
to the chapter 5 / ‘Activating and deactivating the peristaltic pump’.
2) Default ACL set point is displayed in the bottom right corner of the LCD
screen (ACL #1 on the following example).
3.8/ Testing / Priming the peristaltic pump
After installation it is recommended to test the peristaltic pump of the TRi PRO
module and to prime it (self-priming system).
WARNING! Before testing the peristaltic pump, check that all the
pH minus suction and injection connections are correct. Always use
appropriate safety clothes when handling chemical products.
To test the peristaltic pump:
1. Turn on the TRi power pack ( bouton).
2. Press the
button.
3. Use the
buttons to display pH\ACL SETUP.
4. Press
to access the pH\ACL SETUP menu.
5. Use the
buttons to display TEST ACID.
6. A warning message will be displayed briefl y, then press
to start the
pump test. The peristaltic pump will run for approximately 30 seconds and
will stop automatically. If you need to stop the pump immediately, press on
the button.
7. Check that the pump has been correctly primed (the pH minus liquid will be
visible inside the translucent piping).
NOTE: For faster priming of the peristaltic pump, it may be necessary to
repeat steps 2 to 7 several times depending on the length of the pH minus
injection pipe.

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).
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 .
7. Note the displayed pH value CURRENT pH. If the value is higher than 8,2 or
lower than 6,4 there may be a problem with the pH sensor : it is either dirty
or may have been damaged during transportation. Clean the pH sensor (see
chapter 8 / ‘pH & ACL sensors cleaning’) and repeat
steps 1 to 7. If the problem persists, contact your
professional retailer for further assistance.
8. If the pH value displayed on the LCD screen
CURRENT pH is between 6,4 and 8,2 pH, press
to start the calibration process (see pictures
hereafter) (3).
9. Once the calibration is completed, note the new
pH value displayed CURRENT pH. If the value is
different than 7,5 pH, repeat steps 1 to 8 (4).
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 effi cient 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.
