3 Operation and maintenance
NOTE
The unit is operated via the control panel
of the heating and heat pump controller
( operating manual of the heating and heat
pump controller).
3.1 Energy and environmentally-
conscious operation
The generally accepted requirements for an energy-
conscious and environmentally-conscious operation of
a heating system also apply to use of a heat pump.
The most important measures include:
● Nounnecessarilyhighowtemperature
● No unnecessarily high domestic hot water
temperature (note and follow local regulations)
● Do not open windows with just a gap or tilt open
(continuous ventilation); instead, open wide for a
short time (shock ventilation).
● Always ensure that the controller settings are
correct
3.2 Maintenance
Wipe down the outside of the unit only using a damp
cloth or cloth with mild cleaning agent (washing-up
liquid, neutral cleaning agent). Do not use any harsh,
abrasive, acid or chlorine-based cleaning products

5 Transport, installation and
assembly
5.1 Unpacking and transport
Notes on safe transport
There is a risk of injuries or damage to property if the
unit falls or overturns.
There is a risk of cutting your hands on sharp edges
of the unit.
► Wear cut-resistant protective gloves.
Carrying the unit
► Transport the wall-mounted controller to the
installation location.
Unpacking

you do not damage the unit.
2. Dispose of the transport and packaging material
in an environmentally friendly way and in
accordance with local regulations.
5.2 Installation location
ATTENTION
Install the unit inside buildings only.
The installation area must be frost-free and dry. It must
fulltherelevantlocalregulations.
Observe safety and service clearances.
“Installation plan“, page 13 and “Dimensioned
drawings“, page 12
5.3 Assembly
ATTENTION
Ensure the wall has the necessary load-bearing ca-
pacity.
1. Mark holes to be drilled with the help of the drill
template.
“Drill pattern“, page 12
2. Take o the front hood. To do so, unscrew the
