Water Flow Settings - Polytropic PAC 16 Manuel D'instructions

Water flow settings

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
pressure gauge. The setting is modified by opening or closing the setting valve of
the by-pass.
• To increase the pressure on the manometer (pressure gauge), the water flow
passing trough the heat pump must decrease:
-
• To decrease the pressure on the manometer(pressure gauge), the water flow
passing trough the heat pump must increase:
-
For a normal working performance, inlet and outlet valves must be completely
open.
Normal pressure
Pressure inside the refrigerant circuit of the 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 heat transfer.
If the value indicated on the pressure gauge is in the green area between
15 and 20 bars, the water flow is CORRECT.
Set to almost 15 bars when water is cold at the start of the season and 20
bars when water is almost 28 to 30° C.
Warning: The Heat pump needs to operate for 10 to 20 min before the internal
pressure stabilizes
Open the setting valve.
Close the setting valve.
