(Example with eXO® (iQ))
• The cell must always be the last element placed on the pool return pipe (see diagram).
• It is always recommended to install the cell on a by-pass. This assembly is MANDATORY if the
fl ow is in excess of 18 m³/hour to avoid head loss.
• If you installed the cell on a by-pass, it is recommended to fi t a check valve downstream from
the cell and not a manual valve, to avoid any risk of incorrect se ng which could cause poor
circula on in the cell.

2.2 I Installing the temperature sensor (in depending to the model)
• The water temperature sensor displays the water temperature value on the appliance screen and manages
chlorina on according to the temperature. The sensor must measure the temperature of the water
upstream of any possible hea ng system.
• The sensor is designed to be mounted on rigid 50 mm, 63 mm or 1 1/2’’ diameter PVC pipes. Do not install
on any other type of pipe.
• Install the sensor either between the fi lter pump and the fi lter, or between the fi lter and any other
downstream equipment, voir «2.1 I Installing the cell» :
- Drill a hole in the pipe using a 9 mm (max. 10 mm) diameter drill bit, then deburr the hole,
- Install the «O-ring» provided on the sensor body,
- Secure the sensor using the stainless-steel clamping collar provided. Do not use excess strength.

3.4 I Installing the pH minus injec on and suc on pipes
• When handling chemical products, always use appropriate safety equipment
(safety glasses, gloves and jacket).
The peristal c pump rotates in the clockwise direc on. The acid (pH minus) is therefore sucked into the le side of the
pump and injected into the tank from the right side. The pump fl ow direc on can be iden fi ed on the pH Link or Dual
Link module by looking at the two arrows provided.
