contaminants and blockages immediately (see chapter "Position-
ing").

Material losses
Keep the air discharge and intake apertures free from
snow and leaves.
We recommend an annual inspection (establishing the actual
state) and, if required, maintenance (returning the set state) by a
specialist contractor.
6. Troubleshooting
Fault Cause Remedy
There is no hot
water or the heat-
ing system stays
cold.
No power at the appliance.
Check the fuses/MCBs
in your fuse box/
distribution panel.
Replace the fuses/reset
the MCBs if required.
Notify your qualified
contractor if the fuses/
MCBs blow/trip again.
Water is leaking
from the appliance.
The condensate drain may be
blocked.
Clean the condensate
drain as described
in chapter 'Care and
maintenance'.
Condensate is
collecting on the
outside of the ap-
pliance.
The heat pump is drawing heat
from the outdoor air to heat
the building. This can cause the
humidity in the outdoor air to
accumulate as dew or frost on the
cooled heat pump casing. This is
not a defect.
Note
Even when the condensate is draining away correctly,
expect water to drip from the appliance onto the floor.
