Ice On Finned Heat Exchanger; Leakage - Steinbach MINI Bedienungsanleitung

Risk of fire and explosion due to leaking finned heat exchanger!
The refrigerant circuit of the finned heat exchanger contains a highly flammable, odorless gas
under high pressure. Risk of fire and explosion due to uncontrolled escaping of refrigerant.
- Keep heat sources and naked flames away from the heat pump.
- Do not burn or drill into the heat pump.
- Do not use any objects other than those permitted by the manufacturer to speed up the
defrosting process.
- Stop using the heat pump immediately if you suspect a refrigerant leak.
- The refrigerant is odorless. Always keep ignition sources away from the installation site of
the heat pump.
- 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.

Ice on finned heat exchanger

A layer of ice (water condensation) may form on the finned heat exchanger during operation of the heat
pump. This phenomenon is to be expected. Depending on the ambient conditions, it is possible that the
layer of ice is not thawed completely by the automatic defrost function which may lead to a performance
drop and damage to the heat pump.
You can personalize the automatic defrost function:
- (5) Duration for automatic defrosting: sets the duration of the automatic defrost function in minutes.
- (6) Temperature setting for automatic defrosting: as soon as the "current temperature at heat
exchanger" (C) has dropped below this value in °C, the automatic defrost function starts.
- (7) Temperature setting for stopping automatic defrosting: as soon as the "current temperature at
heat exchanger" (C) has exceeded this value in °C, the automatic defrost function stops.
- (8) Temperature setting for stopping automatic defrosting: as soon as automatic defrosting exceeds
the set duration in minutes, the automatic defrost function stops.
Do not use any objects other than those permitted by the manufacturer to speed up the
defrosting process!

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 connected to the heat pump
2
• the seal in the adapter
• the flow pipe inside the heat pump has a leak.
