Connecting the condensate drain

When heating DHW, condensate forms on the inside of
the heat pump module. This condensate needs to be
routed via the condensate drain to a sewer.
1. Secure the condensate drain hose to the conden-
sate drain connector with a hose clip.
!
Please note
Mechanical stress will damage the conden-
sate connection.
To prevent water leaking out, never twist the
condensate drain connector on the appli-
ance.
2. Route the condensate hose as a U-bend and con-
nect with a constant fall and a pipe vent to the pub-
lic sewage system or a neutralising system. If nec-
essary, connect to an on-site trap. Ensure that the
trap is connected securely.
Note
Connecting the condensate drain to rainwater
downpipes is not permissible.

Measures for minimising the pressure drop:
■ Use as few bends as possible.
■ As far as possible, avoid elements that increase the
pressure drop.
■ Route the air intake duct above the air discharge
duct if possible.
3. Check that the condensate can drain freely. Flush
the condensate drain if necessary.

Please note
Freezing condensate in the heat pump leads
to appliance damage.
Should the condensate drain run partially
through unheated rooms, provide thermal
insulation or a ribbon heater around the con-
densate drain on site.
