3.5 Installing the flow switch
The flow switch sensor is factory delivered together with a Ø 50mm T shape collar for
mounting. To fix it, cut the pipe to a length of 30 mm. It is very important to respect the right
direction by checking the arrow representing the water stream flow.

For Ø 63mm, specify when ordering (the flow switch and T shape collar are specicifc). Screw
the water flow switch in such a way that the sensor is correctly positioned in relation with the
water stream flow (contact open when the water is not circulating).
