Adjusting The Set Point(S); Setting The Pool Volume - Zodiac pH Link Instructions For Installation And Use Manual

3.4 Adjusting the set point(s)

The set point is displayed conti nuously on the LCD home screen.
The default setti ng for the pH set point is pH7.2 (pH Link and Dual Link modules).
The default setti ng for the ACL set point is 4 (Dual Link module).
This value provides the ideal compromise to achieve opti mum effi ciency in terms of water disinfecti on.

• The ACL set point displayed does not match the free chlorine concentrati on in the pool. This is the desired
level of 'disinfecti on potenti al' in the water.
• The ACL set point required to reach the opti mum chlorine level is diff erent 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 producti on potenti al: increase the ACL set point.
• To decrease the chlorine producti on potenti al: decrease the ACL set point.
Dual Link module only:
We recommend that you check the free chlorine level in the pool a few days aft er the module is installed to
determine if the rate is ideal (0.5 to 2 ppm, see "2.1 Preparing the pool: water balance"). If, aft er 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 conditi ons of use.
• When the volume of the pool is at the limit between 2 levels, it is bett er 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 fi ltrati on and water treatment systems
are running).
