3.5 Typical arrangement
Note: This arrangement is only an illustrative example.
3.6 Adjusting the bypass
Optimal operation of the heat pump occurs when the cooling gas pressure is 22

2 bar.
This pressure can be read on the pressure gauge next to the control heat pump panel. Under these conditions the
water flow through the unit is also optimal.
Note: Operation without a bypass or with improper bypass adjustment may result in sub ‐ optimal heat pump
operation and possibly damage to the heat pump, which renders the warranty null and void.

Heat Pump
Use the following procedure to adjust
the bypass:

fully open all three valves

slowly close valve 1 until the
water pressure is increased by
approximately 100 to 200 g

Close valve 3 approximately
half-way to adjust the gas
pressure in the cooling system

If the display shows "ON" or
error code EE3, close step by
step the valve 2, to increase
water flow and stop when the
code disappear.
