5. Remove the preinstalled swivel nuts of the units.
6. Use only the preinstalled swivel nuts for further as-
sembly.
7. Before you flare the refrigerant lines, ensure that
there is a swivel nut on the hose.

9. Make sure that the flare has the correct shape.
10. First manually connect the refrigerant lines with the
shut-off valves and the bolts to ensure that they are
in the proper position.
11. Now tighten the bolts using 2 hexagonal wrenches
that have a large enough opening.
12. Use a second wrench to apply counterpressure
when tightening.
See figure.
Installation
Installation is performed as follows:
1. The required line cross-sections are provided in the
"Technical Data” table.
Only use refrigerant lines with refrigerator quality.
2. Decide on a drainage option for the indoor unit and
cut the refrigerant connection line hose accordingly.
3. When assembling the unit, observe the bending radii
of the refrigerant lines and never bend the hose in
the same place twice.
This may cause the line to become brittle or crack.
4. Use the following tools for assembly:
G
Only tools approved for use in cold conditions may
be used
.
13. Insulate the installed refrigerant lines including the
connector against heat.
14. Only use insulation hoses sealed against diffusion
that are suitable for this temperature range.
15. If you have selected Option 2 or 4 (drainage 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 in-
stalled beforehand.
16. 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.
17. Place the refrigerant lines between the indoor unit
and the outdoor part.
Make sure that they are adequately secured and if
necessary, take steps to ensure oil recirculation !

4. Loosen the screws and detach the wall mount from
the unit.
5. Attach the wall mount and hang the unit in the
mount.
6. Secure unit with the screws into the wall mount.
7. After the unit has been mounted, the disassembled
housing panels must be reattached in the reverse or-
der.
8. Work with the refrigerant lines as shown in the fig-
ure below:
