4.4. Condensate drain
Water condensation normally occurs during
heat pump operation; up to 50 liters 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 (40 mm socket)
for condensate drainage. If necessary, it
is possible to place a heating cable in the
drain pipe. The 5m long heating cable for the
drain pipe is not included in supply and can
be ordered as an optional accessory (code
18491).
a)
To the ground to a frost-free depth
The outlet and the space around the
pipe shall 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 properly insulated
or filled with construction PU foam. A
water trap shall be installed inside (see
fig. on the right).
c)
To the building’s sewage system
The drain pipe can be run e.g. to
downpipe drains or eaves.
It is recommended to insulate the outdoor section of drain pipe with thermal insulation.
