Water Flow Detection; Setting Water Flow Switch - Polytropic Advance S Manuel D'instructions

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.
max.
This water pressure switch can be set (if the machine don't stop when there is no water flow
for example)
Normally "flow" LED lighting = water pump working.
If it is not the case: set the water flow switch.

Setting water flow switch

•
Turn the machine off, disconnect the power supply and open the top panel.
•
Check the water flow switch (inside the machine, on the inlet water tube).
•
Remove the plastic protection.
•
On the middle of the water flow switch (octagonal part), take off the plastic cover to
access Hex socket (Allen) screw.
•
Set this screw to accurately detect the water flow:
o If the machine keeps working when the filtration pump stops
o If the machine doesn't start when the filtration pump starts
•
Close the machine.
•
Connect the machine to the power supply and turn the machine on. Check if the
machine "flow" LED light when the water pump starts and stop lighting when the filtration pump
