2. Remove the factory-fitted
protective caps and union
nuts on the connections.
These should be used during
installation.
3. Before flanging the refrigerant
pipes, ensure that the union nut
is fitted on the pipe.
4. Prepare the laid refrigerant
pipes as shown below (Figs
11+12).
5. Verify that the shape of the
flange is correct (Fig 13).
6. First connect and hand-tighten
the refrigerant connections
to ensure they are correctly
seated.
7. Now fully tighten the fittings
using 2 suitably sized open-
ended spanners. Use one
spanner to counter the force
when tightening the fitting
(Fig 14)
.
Only employ tools and compo-
nents suitable for refrigeration
applications.

8. Use insulation hoses which are
designed for this temperature
range and diffusion tight.
9. Lay the refrigerant pipes
from the indoor unit to the
outdoor component. Esnure the
fastenings are adequate and if
necessary, take appropriate oil
return measures!
10. Observe the permitted bending
radius for the refrigerant pipes
during installation. Never bend
a pipe twice in the same place.
Brittle pipes and potential
cracking are the consequences.
11. Use the wall or floor brackets
to fit the outdoor component
against structural parts
approved to support the static
load (refer to the installation
instructions for the brackets).
12. Ensure that structure-borne
sound is not transferred to parts
of the building. Use vibration
dampers to reduce the effects
of structure-borne sound!
13. Prepare the refrigerant pipe
for the outdoor component as
described above.
Supplementary installation notes.
■
If the basic length of the
refrigerant pipe exceeds 5
m, add refrigerant when
commissioning the system
for the first time. See chapter
"Adding refrigerant".

Connections to adjacent room
and fresh air intake
The indoor unit has been designed
to allow the cooling of a second
room as well as the intake of fresh
air.
Installation instructions
Proceed as follows to make the
connections to a second room and
the fresh air intake:
1. Please note that the vaporiser
fins are located directly behind
the cover being removed.
These should not be damaged
under any circumstances
