Condensate pipe for heat pumps with flammable refrigerant

Frost-free condensate discharge must be guaranteed. To ensure proper drainage, the heat pump must be mounted
horizontally.
!
NOTICE! The frost line can vary depending on the climatic region. Observe the regulations in the relevant
countries.

NOTICE! Drainage of condensate into the building is not permitted

Variant 1: Condensate drain in gravel
The condensate that accumulates during operation is drained vertically into a base filled
with gravel.
Requirements:
• Daily percolation of rate of at least 1.5 litre per kW of heat pump heat output
• Diameter of condensate water pipe minimum 50 mm
• Condensate water pipe installed vertically to prevent freezing in winter
!
NOTICE! If the condensate pipe is at risk from frost, provide the associated
condensate drain heating from the list of accessories for the device.
Variant 2: Discharge into sewage, rainwater or drainage channel
The condensate is channelled into a sewer, rainwater or drainage channel through a
condensate pipe in the ground.
Requirements:
• Siphon in condensate pipe below frost line. The water level in the siphon prevents the
refrigerant from getting into the channel if there is a leakage.
• The siphon must have a minimum sealing liquid level of 300 mm
• Pumping systems are not permitted.
Variant 3: Free discharge
Free discharge is only recommended in climate zones with short frost periods. In colder climate zones, the condensate
pipe in areas at risk from frost must be fitted with appropriately dimensioned and regulated electrical trace heating on
the insulated condensate pipe.
