9.7 Preparing the electrical installation
WARNING Electrocution
Carry out all electrical connection and installation work
in accordance with national and regional regulations.
WARNING Electrocution
The connection to the power supply must be in the form
of a permanent connection. Ensure the appliance can be
separated from the power supply by an isolator that dis-
connects all poles with at least 3 mm contact separation.
This requirement can be met by contactors, isolators,
fuses, etc.
!
Material losses
The specified voltage must match the mains voltage.

The electrical data is provided in chapter "Specification". You re-
quire a J-Y (St) 2x2x0.8 mm² cable as a BUS cable.
Note
The appliance includes an inverter for the variable speed
compressor. In case of a fault, inverters can cause DC
residual currents. If RCDs are provided, they have to be
type B AC/DC-sensitive.
A DC residual current can block type A RCDs.

Make sure that the appliance power supply is dis-
connected from the fuse board/distribution panel.

10.1 Transport
!
Material losses
Protect the appliance against heavy impact during
transport.
You can transport the appliance in various ways:
f
f
When carrying, hold on to the narrow sides (transverse
sides) under the base plate.
f
f
Slide a robust pipe through the holes at the bottom of the
appliance frame to create a handle.

If the appliance needs to be tilted during transport only do so
for a short time on one of its longitudinal sides. The longer the
appliance is tilted, the greater the distribution of refrigerant oil
in the system.
f
f
Wait approx. 30 minutes before starting the appliance after it
has been tilted.
10.2 Siting
f
f
When siting the appliance, observe the air discharge direc-
tion (see chapter "Preparations / Sound emissions").
f
f
Mount the appliance on the T-support or wall mounting sup-
port. Observe the installation instructions for the mounting
bracket used.
