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 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 through
the heat pump must decrease:
• Open the setting valve.
To decrease the pressure on the manometer (pressure gauge), the water flow passing through
the heat pump must increase:
• Close the setting valve.
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 1,5 and 2,5,
the water flow is CORRECT.
Set to almost 1,5 when water is cold at the start of the season and 2,5 when water is
almost 28 to 30° C.
Warning: The Heat pump needs to operate for few minutes before the internal pressure
stabilizes
Abnormal pressure
If the pressure is too high or too low, it indicates that the water flow circulating inside the heat
pump is not correct.
You need to adjust the water flow by opening or closing the by-pass valve. Open little by little it
if the pressure is in the yellow area and close it little by little if the pressure is in the red area
until it remains stable in the green area.
Pressure gauge must be between value 0.5 and 1 when the machine is stopped. If the
value is 0, don't start the machine (contact your seller).
Frequency of settings
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 the pool heat pump is turned on and water is cold.
• When the pool temperature is increasing.
• When the desired water temperature is reached.
Thereafter the flow does not need to be regulated any further. Simply check the pressure once
in a while to ensure that the pool heat pump is working normally and that the water flow hasn't
changed.
