Heating Priority; Water Flow Detection; Water Flow Switch Setting - Polytropic NeoPAC Serie Manuel D'instructions

NeoPAC

Heating priority

It is possible to connect the water filtration pump to the heat pump, in order to start the filtration
pump if the water is not at desired temperature.
This connection must be done by connected P1 connection from the heat pump to the neutral
connection of the filtration pump and P2 to the phase connection of the filtration pup.
Maximum intensity used by the filtration pump wust be lower than 15A !
It is very important to connect P1 to neutral and P2 to phase. An inversion will destroy
heat pump and/or filtration pump.

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:
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.

Water flow switch setting

•
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).
•
Take off 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 detect correctly 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
2 m
Screw it (1/2 turn).
