3.6 Setting the By-pass
Optimal operation of the heat pump is achieved if the refrigerant gas is
at a pressure of 20+/-2 bar.
This pressure may be read off from the pressure gauge next to the
service panel of the heat pump. The correct setting also ensures that the
optimal water flow always passes through the appliance.
Remark – The lack of a by-pass or poor setting may cause the heat
pump not to operate optimally, or even become damaged. In that
case the warranty is invalidated.
Follow this procedure to set
the by-pass:
● completely open the 3
valves
● close valve 1 gradually
until the water pressure has
risen by around 100-200
gram (see also 3.8)
● close valve 3 to around
halfway to set the pressure
of the refrigerant gas in the
appliance.
The by-pass has to be built
as shown:
VALVE 1: Slightly closed
(water pressure increased
with just 100 to 200 gr)
VALVE 2: Completely open
VALVE 3: Half way open
