Calibrating the sensors (see § 3.3).
• Press
, then use the
or
keys to display 'CALIB. PH' or 'CALIB. PH/ACL', then press
.
• Use the
or
keys to display 'PH SET POINT' or 'ACL SET POINT', then press
.
• Use the
or
keys to change the set point value.
• Press
or wait 30 seconds to exit.
•
The ACL set point displayed by the TRi PRO does not match the free chlorine concentration in the pool. This is
the desired level of 'disinfection potential' in the water.
•
The ACL set point required to reach the optimum chlorine level is different in every swimming pool. A period
manual measurement of free chlorine level in the pool is therefore necessary to adjust this ACL set point.
•
To increase the chlorine production potential: increase the ACL set point.
•
To decrease the chlorine production potential: decrease the ACL set point.
We recommend checking the free chlorine level in the pool a few days after installing the TRi PRO, to deter
-
mine if the optimum level has been reached (0.5 to 2 ppm, see § 2.1). If, after this period, the free chlorine level
is unsuitable, the ACL set point must be changed.
3.5 Setting the pool volume
List of levels with corresponding volumes:
•
Level 1: For small pools up to 40 m³
•
Level 2: For mid-size pools from 40 to 60 m³ (default level)
•
Level 3: For large pools between 60 and 110 m³
•
Level 4: For very large pools over 110 m³
•
These values are for guidance only; the choice may vary according to the conditions of use.
•
When the volume of the pool is at the limit between 2 levels, it is better to use the higher level.
•
However, we recommend not 'over-sizing' the choice of level, to avoid using too much pH minus.
•
A dose of pH minus is injected into the pool every 2 hours (when the filtration and TRi chlorinator systems are
running).
• Press
, then use the
or
keys to display 'CALIB. PH' or 'CALIB. PH/ACL', then press
.
• Use the
or
keys to display 'POOL VOLUME', then press
.
• Use the
or
keys to select the desired level appropriate to the pool size.
• Press
to confirm the choice then press
or wait 30 seconds to exit.
3.6 Peristaltic pump
3.6.1 Test / priming the peristaltic pump
After installation, we recommend testing the peristaltic pump for the TRi pH or TRi PRO module and priming it (system
normally self-priming).
•
Before testing the peristaltic pump, ensure that all pH minus suction and injection pipes are correctly con
-
nected.
•
Always use appropriate safety equipment when handling chemical products.
•
Switch on the TRi power pack (
button).
• Press
, then use the
or
keys to display 'CALIB. PH' or 'CALIB. PH/ACL', then press
.
• Use the
or
keys to display 'TEST DOSAGE'.
•
A warning will be displayed briefly, then press
to confirm starting the pump. The peristaltic pump will operate for
about 30 seconds and will stop automatically.
•
If the pump must be stopped immediately, press
.
•
Confirm that the pump is primed (pH minus solution will be visible in the translucent pipes).
