Water Flow Setting - Polytropic PAC 31 Manuel D'instructions

Polytropic

Water flow setting

To optimize the performance of the heating process, it is advisable to regulate the
water flow through the pool heat pump.
The adjustment must be carried out according to the indication given by the
preassure gauge.
You can set the optimal water temperature by using the valves of the by-pass-
system.
Normal pressure
Pressure inside the refrigerant circuit of heat pump and the water flow influence
each other.
To work correctly, a water flow of 5 to 7 m³/h (100 l/min), should be maintained
for maximum heating power.
If the Value indicated on the pressure gauge is in the green area, the water flow
is CORRECT.
Attention: The Heat pump must work 10 to 20 min before the internal pressure
stabilizes and the settings on the by pass valves should be done.
Abnormal pressure
If the pressure is too high or too low (yellow or red area), it indicates that the
water flow inside heat pump is not correct.
You need to set water the flow by opening or closing the by-pass valve. Open
it if the pressure is in the red area and close it if the pressure is in the yellow area.
Setting frequency
The optimum water flow through the pool heat pump depends mainly on the
water temperature and to a lesser extent on the ambient air temperature.
Ideally the settings should be done:
• When pool heat pump is turned on and water is cold.
