Checking The Gas Pressure (Manometer); Leakage - Steinbach Waterpower 8500 Originalbetriebsanleitung

- Contact an authorized qualified person if you suspect refrigerant leaks.
- Observe the national regulations on gas.
- All persons involved in work on the refrigerant circuit must have a valid certificate from an
industry accredited certification body that ensures competence in handling refrigerants
according to a specific assessment recognized by industry associations.

Checking the gas pressure (manometer)

The manometer measures the pressure of the gas phase in the refrigerant circuit of the finned heat
7
exchanger and thus provides information about the state of the refrigerant during the operation of the
heat pump.
Check the pressure displayed at the manometer
Liquid is visible in the manometer. This is not a defect.
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 . If the drain connection piece

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.
