5. Maintenance and care
Material losses
Only qualified contractors may perform maintenance
work, such as electrical safety checks.
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
fault Cause remedy
There is no hot
water or the
heating system
remains cold.
No power at the appliance. Check the fuses / MCBs in
your fuse box / 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".
The heater gets
warm, but the
rooms are not
heated to the
required temper-
ature.
The dual mode temperature is
set too low.
Increase the dual mode
temperature to e.g. 0 °C.
The building is a new build
and is in the screed drying
phase.
Increase the dual mode
temperature to +5 °C.
After 1 to 2 years the dual
mode temperature can be
reset to e.g. -3 °C.
fault Cause remedy
There is a loss of
pressure in the
heating system.
Water drips from the safety
valve.
Use the inspection port
to check whether water
is passing from the safety
valve hose into the conden-
sate pan. Call your quali-
fied contractor.
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.
