-When calibraon is nished, check that the value displayed equals 7.5, otherwise repeat the calibraon.
• ACL = 'XXX'
-Start the calibraon procedure by pressing or , the procedure lasts about 15 seconds,
-If the value is 700: calibraon is correct
-If the value is not 700: repeat the calibraon steps. If the problem persists, contact your reseller.
• Press or or wait 30 seconds to exit.
3.4 Adjusting the set point(s)
The set point is displayed connuously on the LCD home screen.
The default seng for the pH set point is pH7.2 (pH Link and Dual Link modules).
The default seng for the ACL set point is 4 (Dual Link module).
This value provides the ideal compromise to achieve opmum eciency in terms of water disinfecon.
• Calibrang the sensors (see § 3.3).
• Press or the use the or keys to display "CALIB. PH" or "CALIB. PH\ACL", then press or
.
• Use the or keys to display 'PH SET POINT' or 'ACL SET POINT', then press or .
• Use the or keys to change the set point value.
• Press or or wait 30 seconds to exit.
• The ACL set point displayed does not match the free chlorine concentraon in the pool. This is the desired level
of 'disinfecon potenal' in the water.
• The ACL set point required to reach the opmum chlorine level is dierent 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 producon potenal: increase the ACL set point.
• To decrease the chlorine producon potenal: decrease the ACL set point.
Dual Link module only:
We recommend that you check the free chlorine level in the pool a few days aer the module is installed to
determine if the rate is ideal (0.5 to 2 ppm, see §2.1). If, aer 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 condions of use.
• When the volume of the pool is at the limit between 2 levels, it is beer 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 ltraon and water treatment systems
are running).
