If the value is 700: calibration is correct
-
If the value is not 700: repeat the calibration steps. If the problem persists, contact your reseller.

3.4 Adjusting the set point(s)
The set point is displayed continuously on the LCD home screen.
The default setting for the pH set point is pH7.2 (pH Link and Dual Link modules).
The default setting for the ACL set point is 4 (Dual Link module).
This value provides the ideal compromise to achieve optimum efficiency in terms of water disinfection.

• The ACL set point displayed 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.
Dual Link module only:
We recommend that you check the free chlorine level in the pool a few days after the module is installed to
determine if the rate is ideal (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 water treatment systems
are running).
