3.5 Typical arrangement
Note: This arrangement is only an illustrative example.
3.6 Adjusting the bypass
To pool
Out
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.
In
Heat Pump
Use the following procedure to adjust
the bypass:
From pool
- 8 -

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.
