Attaching the wall mount
The units must be attached with suitable screws and
dowels. The attachment points are displayed in the fol-
lowing figure.
Lead-through options
Prior to installation, take a look at the various options
for lead-throughs of the refrigerant and condensation
pipes and control lines (see figure below).
1 Opening on the wall rear 2 Opening through the wall right
3 Opening through the wall left 4 Opening on the wall left
Assembling the indoor unit
Install the indoor unit as follows:
1. The required pipe diameters are provided in the
"Technical Data” table of the outdoor unit.
Only use refrigerant pipes with refrigerator quality.
2. Decide which drainage option you want to use for
the indoor unit and cut the refrigerant pipes accord-
ingly.

13. Lay the refrigerant pipes from the indoor unit to the
outdoor unit.
14. Connect the refrigerant pipes to the outdoor unit as
described in the operating instructions of the out-
door unit.
3. When assembling the unit, observe the bending radii
of the refrigerant pipes and never bend the hose in
the same place twice. This may cause the pipe to
become brittle or crack.
4. Remove the preinstalled swivel nuts of the units.
5. Keep in mind that the indoor units have been filled
with dry nitrogen as a sealant at the factory.
The pressurised nitrogen is released when the
swivel nuts are loosened.
6. When assembling the unit, only use tools suitable
for low temperature ranges.
7. Work with the pipes as described in the operating
instructions of the outdoor units.
8. Insulate the installed refrigerant pipes including the
connector against heat.
9. Only use insulation hoses sealed against diffusion
that are suitable for this temperature range.
10. If you have selected option 2 or 4 (opening through
the wall), guide the condensation water and control
line through the wall lead-through to the indoor unit.
If you also need a condensation pump, it must be
installed beforehand.
11. If, due to structural design conditions, it is not possi-
ble to guide the condensation pipe through as well,
make sure that the condensation can drain freely at
all times.
12. Hang the indoor unit leaning slightly to the back in
the previously assembled wall mount and press the
bottom of the unit into the mount.
Do not damage the pipes and ensure that they are
in the correct position.
