5. Maintenance and care
!
Material losses
Maintenance work, such as checking the electrical safety,
may only be carried out by a qualified contractor.
A damp cloth is sufficient for cleaning all plastic and sheet metal
parts. Never use abrasive or corrosive cleaning agents.
Regularly check the condensate drain (visual inspection). Remove
any contaminants and blockages immediately.

Material losses
Keep the air discharge and intake apertures free from
snow and leaves.
Remove any leaves or other foreign bodies from the evaporator
fins periodically.
We recommend a regular inspection (to establish the current con-
dition of the system), and maintenance by a qualified contractor
as required (to restore the system to the ideal condition).
6. Troubleshooting
There is no hot
water or the
heating system
remains cold.
No power at the appliance.
Check the fuses/MCBs in
your distribution board.
Replace the fuses/reset the
MCBs if required. Notify
your qualified contractor if
the fuses/MCBs blow/trip
again after switching the
system back on.
Water is leaking
from the appli-
ance.
The condensate drain may be
blocked.
Clean the condensate drain
as described in "Mainte-
nance and care".
Condensate is
collecting on the
outside of the
appliance.
The heat pump extracts heat
from the outdoor air in order
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.
The fan runs
when the
compressor is
switched off.
At outside temperatures below
10°C, the fan is regularly
started at the lowest speed
when the compressor is idle.
This prevents the evaporator
and fan from freezing or icing
up due to water draining
off. At temperatures above
the freezing point, the time
between two defrost cycles is
increased, thereby improving
overall efficiency.
The appliance
produces rhyth-
mic scraping or
grinding noises.
Ice has formed on the air
grille, on the fan blades or in
the air routing.
Call your qualified contrac-
tor (see chapter "Installa-
tion/ Troubleshooting/ Fan
noise").
Note
Even when the condensate is draining away correctly, it
is not unusual for water to drip from the appliance onto
the floor.
If you cannot remedy the fault, contact your qualified contractor.
To facilitate and speed up your request, provide the number from
the type plate. The type plate is located at the front top, on the
right or left-hand side of the casing.
