Supplementary
installation notes
■
The connections to the
refrigerant pipes may differ
when combining the outdoor
component with certain indoor
units. In this case, fit reducers or
flared fittings to the indoor unit
(included).
■
If the basic length of the
refrigerant pipe exceeds 5 m, add
refrigerant when commissioning
the system for the first time. (See
section "Adding refrigerant").
Only employ tools and
components suitable for
refrigeration applications.

torque:
1 4 “ 15-20 Nm
3 8 “ 33-40 Nm
1 2 “ 50-60 Nm
5 8 “ 65-75 Nm
3 4 “ 95-105 Nm
5. Verify that the shape of the
flange is correct(Fig 9).
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
10)
.
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. Ensure that 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.
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.
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).
Verify the correct assignment
of injection and suction pipes.
Observe the letter markings!
Do no mix up the connections
between circuits.
