Unscrew the white cap and withdraw the sensor from its vial of liquid. Remove the black o-ring and the
white cap from the sensor and replace them on the vial (keep this to winterize the sensor).
Unscrew the black nut from the tee, be careful not to lose the removable parts.
Thread the black ring, the metallic washer and the compression ring onto the body of the sensor.
Make sure that the o-ring is correctly positioned on the tee union.
Push the end of the sensor into the union until the end of the sensor is located in the centre of the pipe
through which the water is flowing.
Screw the nut firmly onto the union, and check that the sensor cannot be removed by pulling gently.
Next, connect the two sensors to the electrical panel.

IMPORTANT The active tips of the pH and ORP sensors must always be immersed, see the section
on hydraulic connections.

Installing the electrical/ control panel

Reminder:
The control panel is IP56 rated (according to the standard EN 60529). It will not be damaged by splashing,
however it should be located at least 3.5 metres from the pool.
If this is not possible, it may be positioned closer to the pool, but under no circumstances closer than 2
metres, subject to the condition that its power cable is directly connected to a 30mA residual current device
(as stipulated in the standard NF C 15-100).
Mount the panel on a flat, solid, vertical wall in the plant room using the 2 mounting brackets. For added
safety, position the panel at a height inaccessible to children.
