Water flow detection

The heat pump only operates whenever there is water flow circulating inside. All
models are equipped with a water pressure switch that detects the pressure of
the hydraulic circuit.
Warning: If the appliance is installed below the level of swimming pool
(below 2 m - 80"), residual pressure could prevent water pressure switch
from operating correctly.
This water pressure switch can be set:
Check its position on the top of plastic water tank, put off the plastic cap
and set it with a setting screw (on the middle of the water pressure
switch). Be sure that it starts and stops at the same time than the
filtration pump.
