Setting The Pool Size; Acl Sensor Calibrating Procedure - Zodiac TRiPRO Notice De Montage

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:
3
- Size #1 : For small pools up to 60 m
3
- Size #2 : For mid-size pools between 60 and 90 m
3
- Size #3 : For large pools between 90 and 120 m
3
- Size #4 : For very large pools more than 120 m
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).
To set the pool size :
6. From the default display on the LCD screen, press the (MENU) button.
7. Use the (UP)/(DOWN) buttons to display 'pH/ACL SETUP', then press (SELECT).
8. Use the (UP)/(DOWN) buttons to display 'SET POOL SIZE', then press (SELECT).
9. Use the (UP)/(DOWN) buttons to select the pool size corresponding to your pool volume (default
setting is #1).
10. Press (SELECT) to confirm your choice then press (MENU) button 2 times or wait 30 seconds for
the TRi power pack to return to the default display on the LCD screen.
NOTE : One dose of pH minus is released in the pool every 2 hours (when filtration system and TRi unit
are both operating).
WARNING ! It is recommended to select the lowest possible pool size setting in order to avoid pH
minus overdosing

4.4/ ACL sensor calibrating procedure

1. Remove the ACL sensor (red) 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 !
2. Place ACL sensor in a sample of 'ORP 700 mV' orange buffer solution (provided, see picture below).
