Condensate drainage connection
If the temperature falls below the dew point, con-
densation will form on the finned condenser
during heating mode.
A condensate tray should be installed on the
underside of the unit to drain any condensate.
n
The condensate drainage line should have an
incline of min. 2%. This is the responsibility of
the customer. If necessary, fit vapour-diffusion-
proof insulation.
n
When operating the unit at outside tempera-
tures below 4 °C, ensure the condensate
drainage line is laid to protect it against frost.
The lower part of the housing and condensate
tray is also to be kept frost free in order to
ensure permanent draining of the condensate.
If necessary, fit a pipe heater.
n
Following installation, check that the conden-
sate run off is unobstructed and ensure that the
line is durably leak tight.
