- Ensure that the ACL 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.
4.5/ 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.
Remark : Displayed ACL set point onto default LCD screen does not correspond to free chlorine
level into pool’s water ! It’s only the selected level of ‘water’s disinfection potential’ (ACL).
Requested ACL set point to reach an optimal free chlorine level is different in every pool. A regular
manual free chlorine analysis will be necessary to adjust ACL set point.
TRi PRO module has 6 different ACL set points (corresponding to 6 different ORP levels).
TRi PRO module default ACL set point is #1.
NOTE
: It is recommended to keep the original ACL set point (#1) during the first few days after having
installed the TRi PRO module to see if an acceptable free chlorine level has been reached (see chapter
7 / ‘Water balance’). If free chlorine level is too low after this startup period, it will be necessary to
increase the ACL set point.
To change the ACL set point :
1. Ensure that the ACL sensor has been calibrated (see above procedure).
2. From the default display on the LCD screen, press the (MENU) button.
3. Use the (UP)/(DOWN) buttons to display ‘pH/ACL SETUP’, then press (SELECT).
4. Use the (UP)/(DOWN) buttons to display ‘ACL SETPOINT’, then press (SELECT).
5. Use the (UP)/(DOWN) buttons in order to change the set point value and press (SELECT) to validate.
6. Press (MENU) button 2 times or wait 30 seconds for the TRi power pack to return to the default
display on the LCD screen.
IMPORTANT REMARK : It’s not possible to manually adjust the chlorine output when TRi PRO
module is installed onto a TRi power pack ((UP)/(DOWN) buttons are inoperative). Only (BOOST)
and (LOW) modes are usable (see TRi salt water chlorinator user manual).
5/ Activating and deactivating the peristaltic pump
For safety reasons, the peristaltic pump of the Zodiac TRi PRO module is not activated when delivered.
When the TRi PRO module is connected to the TRi power pack, the peristaltic pump is programmed to
start operating automatically approximately 8 hours after turning it on. During this period, the default
display on the LCD screen will display ‘pH ---‘.
To immediately activate the peristaltic pump :
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 ‘ACID PAUSED’.
