9.8 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 3mm contact separation.
This requirement can be met by contactors, isolators,
fuses, etc.
!
Material losses
The specified voltage must match the mains voltage. Ob-
serve the type plate.
!
Material losses
Provide separate fuses/MCBs for the three power circuits,
i.e. those of the appliance, the control unit and the elec-
tricemergency/booster heater.
Use cables with the relevant cross-sections. Observe the ap-
plicable national and regional regulations.

The electrical data can be found in the chapter "Specification".
You require a screened J-Y (St) 2x2x0.8mm² cable as a bus cable.
Note
The appliance includes an inverter for the variable speed
compressor. In the event of a fault, inverters can cause
DC residual currents. If RCDs are provided, they must be
type B AC/DC-sensitive.
A DC residual current can block type A RCDs.
Ensure that the appliance power supply is discon-
nected from the distribution board.
10. Installation
Note
The device is designed in such a way that it can be po-
sitioned and connected without removing the cover or
side panels.
10.1 Transport
When transporting the appliance, be aware of its centre of
gravity.
- The centre of gravity is in the area where the compressor is
located.
Protect the appliance against heavy impact during transport.
Use the recessed grips provided at the sides.
D0000071298
- If the appliance needs to be tilted during transport, this must
only be for a short time and it must only be tilted on one of
its longitudinal sides. When transporting the appliance, en-
sure the compressor is on the upper appliance side.
- The longer the appliance is tilted, the greater the distribution
of refrigerant oil inside the system.
Wait approximately 30minutes before starting the appliance
after it has been tilted.
