If the outdoor unit is positioned higher than the indoor unit, install a
siphon-shaped elbow on the gas side after no more than 6 m and every
6 m thereafter (
Fig. 3, [1]).
▶ Observe maximum pipe length and maximum difference in height
between indoor unit and outdoor unit.

Table 5
The length of the pipework without additional refrigerant filling is 7.5 m.
With longer pipework, the refrigerant is filled according to pipe length. In
doing so, the maximum fill volume is 1100 g.

Installation
3.1
Before installation
CAUTION
Risk of injury from sharp edges!
▶ Wear protective gloves during installation.
CAUTION
Danger of burns!
During operation the pipes become hot.
▶ Make sure, that the pipes cooled down before touching them.
▶ Check the scope of delivery for damage.
▶ Check whether a hissing sound due to negative pressure can be
detected when opening the pipes of the indoor unit.
3.2
Requirements for installation site
▶ Observe minimum clearances (
Fig. 4).
NOTICE
Device damage caused by snow!
Snow accumulating underneath the outdoor unit may impair operation
and damage the device. If snow clogs the condensate pipe, ice will
gather and damage the unit.
▶ Ensure that the condensate pipes of the outdoor unit cannot be
clogged and are always unobstructed, and that water can easily run
off.
▶ For heating mode and defrosting, ensure that a minimum distance of
250 mm is always maintained between the snow and outdoor unit.
Indoor unit
▶ Do not install the indoor unit in a room in which open ignition sources
(for example: open flames, an operating wall mounted gas boiler or
an operating electric heating system) are in operation.
▶ The appliance can be installed in a room with a floor area of 4 m
2
, if
the installation height is at least 2.5 m. If the installation height is
lower, the floor area must be accordingly larger.
▶ The installation location must not be higher than 2000 m above sea
level.
▶ Keep the air inlet and air outlet clear of any obstacles to allow the air
to circulate freely. Otherwise poor performance and higher noise
levels may occur.
▶ Keep TV, radio and similar appliances at least 1 m away from the unit
and the remote control.
▶ Mount the indoor unit on a wall that absorbs vibrations.
Outdoor unit
▶ The outdoor unit must not be exposed to machine oil vapour, hot
spring vapour, sulphur gas, etc.
▶ Do not install the outdoor unit directly next to water or where it is
exposed to sea air.
▶ The outdoor unit must always be kept free of snow.
▶ There must be no disruption caused by extract air or operating noise.
▶ Air should be able to circulate freely around the outdoor unit, but the
appliance must not be exposed to strong wind.
▶ Condensate that forms during operation must be able to drain off
easily. Lay a drain hose if required. In cold regions, installation of a
drain hose is not advisable as it could freeze.
▶ Place the outdoor unit on a stable base.
3.3
Unit installation
NOTICE
Incorrect assembly can cause material damage.
If the unit is assembled incorrectly, it may fall off the wall.
▶ Only install the unit on a solid flat wall. The wall must be capable of
supporting the weight of the unit.
▶ Only use screws and wall plugs that are suitable for the wall type and
weight of the unit.
3.3.1
Installing the indoor unit
▶ Open the box and lift the indoor unit out and up.
▶ Place the indoor unit with the moulded parts of the packaging face
down.
▶ Remove the mounting plate on the rear of the indoor unit.
▶ Determine the installation location, taking the minimum clearances
into consideration (
Fig. 2).
▶ Attach the mounting plate with a screw and wall plug via the centre
hole to the wall and align horizontally (
Fig. 4.[1]).
