2.2 I Hydraulic connecti ons

2.2.1 Sensor and injecti on point locati on
• The pH sensor must be installed more than 30 cm before or aft er a piping bend. Use the opti onal
POD kit if necessary. Failing to follow this positi oning can lead to incorrect or unstable measure-
ments.
• The ti p of the pH sensor must not be in contact with the pipe.
• Never install a pH sensor before the fi ltrati on pump or between the pump and the fi lter. This
would cause random readings and a shortened service life.
• The pH sensor must be placed aft er the fi lter and before the heati ng system,
• It must be placed verti cally or sloping at a maximum of 45°; it should never point downwards.
• The injecti on point must be the last element on the pool circuit, aft er any heati ng and water treatment
systems.
2.2.2 Sensor and injecti on point installati on
• There must be at least 60 linear cm between the sensor and the injecti on point. If this is not possible, use
the POD kit available as an opti 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
opti on.
• The POD kit is recommended if a Redox (chlorine) regulati 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 locati ons for the pH sensor
and the injecti on point.
• Then install the fi xture collars.
• Use Tefl on tape to make sure the threads on the sensor holder, the injecti on valve and its adapter are
waterti ght.
• Ensure that the 2 gaskets, the O-ring ( ) and the sheet gasket ( ) remain on the sensor (in the order
sti pulated) during assembly in order to guarantee the equipment's impermeability.
