3.5. Condensate drain
Water condensation normally occurs during heat pump operation; up to 50 litters of condensate can
be generated per day, depending on the operating conditions. The heat pump is equipped with a
condensate tray. A heating cable is installed in the condensate tray as a protection against freezing.
The condensate tray shall be connected to a drain pipe for condensate drainage. If necessary, it is
possible to place a heating cable in the drain pipe. The heating cable to the drain pipe is not included
in supply and can be ordered as an optional accessory (code 18491).
The drain pipe can be run:
a) to the ground to a frost-free depth
– the outlet and the space around the pipe must be filled
with crushed stone to ensure sufficient condensate drain, the underground section of the pipe can
be perforated,
b) into the building, in its sewage system
– the through-wall passage shall be above the ground
and a water trap shall be installed inside (see Fig. below),
c) to the building’s drainage system, e.g. downpipe drains or eaves
It is recommended to insulate the drain pipe with thermal insulation.
