2.1.1 Water balance

It is essen al that the pool water balance is controlled and adjusted before installing the appliance. Making

sure that the pool water balance is correct from the very start will reduce the likelihood of encountering

problems on the  rst days of opera on or during the season the pool is in use.

Even though it is an automa c regula on system, it is essen al to carry out regular water analyses

to check the water balance parameters.

2.1.2 Appliance injec on programme

Example of 4 cycles with a set point at 7.4 pH and acid regula on (standard alkalinity):

 : 20% injec on (2 min) & 80% pause (8 min)

 : 50% injec on (5 min) & 50 % pause (5 min)

 : 75% injec on (7 min 30 sec) & 25% pause (2 min 30 sec)

 : 100% injec on (10 min)

• The injec on programme is of course inverted when a basic dosage is selected.

• Ac ve chlorine is more eﬃ cient with the correct pH level.

• Maximum release rate is 1.5 L/h. This dosage ensures that the set point is reached quickly and

accurately.

• This propor onal injec on is cyclic and the cycle dura on is 10 minutes. The

dose will change according to the distribu on of injec on  mes and pauses.

The propor onality adjusts automa cally and the balancing between the

di erent doses is made in 0.15 pH steps.

2.1.3 Adjus ng dosage according to alkalinity

The pH level of water is poten ally unstable. Its stability is governed by the level of water alkalinity (also called "TA" for

‘‘Total alkalinity’’). If the TA is low (< 100 ppm), the pH will become poten ally unstable and conversely if the TA is high

(>150 ppm).

In order to always achieve op mal water balance, the appliance has a feature that allows users to adjust the quan ty of

corrector product poten ally injected depending on the water TA (see §"3.5.4 "Dosage" menu")

2.2.1 Sensor and injec on point loca on

• The pH sensor must be installed more than 30 cm before or a� er a piping bend. Use the op onal

POD kit if necessary. Failing to follow this posi oning can lead to incorrect or unstable measure-

ments.

• The  p of the pH sensor must not be in contact with the pipe.

• Never install a pH sensor before the  ltra on pump or between the pump and the  lter. This

would cause random readings and a shortened service life.

• The pH sensor must be placed a� er the  lter and before the hea ng system,

• It must be placed ver cally or sloping at a maximum of 45°; it should never point downwards.

• The injec on point must be the last element on the pool circuit, a� er any hea ng and water treatment

systems.



2.2.2 Sensor and injec on point installa on

• There must be at least 60 linear cm between the sensor and the injec on point. If this is not possible, use

the POD kit available as an op on or a check valve.

• Fixture collars (or the POD kit) must be installed on rigid Ø50 PVC pipes. A Ø63 adapter is available as an

op on.

• The POD kit is recommended if a Redox (chlorine) regula on module has also been installed.

• Maximum pressure must not exceed 1.5 bar.

• Drill a hole with a diameter between 16 and 22 mm on the pipe at the selected loca ons for the pH sensor

and the injec on point.

• Then install the  xture collars.

• Use Teﬂ on tape to make sure the threads on the sensor holder, the injec on valve and its adapter are

water ght.

• Screw down the one or more sensor holders onto the  xture collar or a POD kit (op onal), 
