Check the pressure displayed at the manometer
The heat pump has an integrated pressure safety which automatically
switches the heat pump off if the maximum permissible operating pressure
of 4.3 MPa (43 bar) is exceeded.
Typical refrigerant pressure values:
- Not in operation: about 1.5 MPa
- Standby mode: about 1.5 MPa
- Operating mode: about 3.5 MPa
- Defrosting mode: temporarily increased pressure, which causes the temperature of
the refrigerant to rise and melt the ice that has formed.

Leakage

If fluids are coming out of the heat pump, it can be one of the following:
- Condensation water
- Pool water
- Refrigerant
Condensation water
Condensation water forming during operation is normal. There is no damage. The surface
of the finned heat exchanger gets cold, humidity in the ambient air condenses and, in
extreme cases, freezes. Condensation water collects in the bottom tray and is discharged
through a hole and via the drain connection piece
plugged up, the condensation water cannot drain from the heat pump and larger
amounts collect in the heat pump.
Pool water
Leaking pool water indicates that:
• the hose is not correctly installed on the adapter.
• the adapter is not correctly screwed onto the heat pump.
• the seal in the adapter is defective or missing.
• the flow pipe inside the heat pump has a leak.
Refrigerant
Leaking refrigerant indicates that the refrigerant circuit in the finned heat exchanger has
a leak. Contact a qualified person immediately if you detect a leak in the refrigerant
circuit.
Keep in mind that refrigerants are odorless.
every time you use the heat pump.
