Condensate Pipe For Heat Pumps With Flammable Refrigerant - Dimplex LA 1118CP Montage- Und Gebrauchsanweisungen

English
6.5 Condensate pipe for heat
pumps with flammable
refrigerant
Frost-free condensate discharge must be guaranteed. To en-
sure proper drainage, the heat pump must stand horizontally.
NOTE

The frost line may vary according to the climatic region.
The regulations of the countries in question must be
observed.
Version 1
The condensate, which accumulates during operation, must be
drained vertically into a base filled with gravel. A daily seepage
capacity of at least 1.5 litres per kW heat output of the heat
pump shall be provided and the diameter of the condensate
water pipe should be at least 50 mm.

NOTE
The condensate water pipe must be installed vertically to
prevent it from freezing in winter. If the condensate pipe is
exposed to frost, trace heating must be provided.
EN-14
Version 2
The condensate is channelled into a sewer, rainwater or drain-
age channel via a condensate pipe in the ground. The conden-
sate pipe contains a siphon below the frost line
level in the siphon prevents the refrigerant from getting into the
channel if there is a leakage. Pumping systems are impermissi-
ble! The siphon must have a minimum sealing liquid level of
300 mm.

Version 3
Free discharge is only advisable in climate zones with short
frost periods. In colder climate zones, the condensate pipe in
areas at risk from frost must be fitted with a suitably dimen-
sioned and regulated electrical trace heating on the insulated
condensate pipe.
Version 4
The condensate pipe may lead into the building. The wall open-
ing must be air tight. Inside the building, the pipe connection to
the waste water pipe must be equipped with a siphon. The si-
phon must be protected against drying out. If this is not possi-
ble, a siphon that closes when it runs dry must be fitted. Lifting
units are not permitted.
