Unit installation
The indoor unit is attached by
means of a wall bracket, taking
into consideration the air discharge
side located in the lower part.
1. Mark the mounting points on
the structurally permissible
building sections according
to the dimensions of the wall
bracket.
2. If necessary, remove the break
out opening of the housing.
3. Connect the refrigerant pipes
to the indoor unit as described
below. The flexible refrigerant
pipe and the electrical control
cable are pre-installed.
4. Suspend the indoor unit on the
wall bracket by tilting it back
slightly and then by pressing
the bottom part of the unit
against the bracket

and anchors.
Installation
Installation should only be
performed by authorised
specialists.
NOTE
Oil return measures
If the outdoor component is
installed at a higher level than
the indoor unit, suitable oil return
measures must be taken. Usually,
an oil pump bend is installed
for every 2.5 metres of height
difference.
Connection of
refrigerant pipes
The refrigerant pipes should be
connected by the customer on the
right-hand side of the outdoor
component.
1. Use the wall or floor brackets to
fasten the outdoor component
where structurally allowed
(refer to the installation
instructions for the brackets).
2. Ensure that structure-borne
sound is not transferred to
the building. Use vibration
dampers to reduce the effects
of structure-borne sound!
3. Prepare the refrigerant pipes
for the outdoor component as
described above.
5 Connecting
Extending the
refrigerant pipes
The 2 m refrigerant pipe contained
in the delivery may be extended by
3 metres or 8 metres.
1. Remove the protective caps
from the quick connectors.
2. Connect the suitable pipes and
