6.3 Connection of
quick-release couplings
The refrigerant pipes should be connected by the
customer on the right-hand side of the outdoor
component. The pre-filled refrigerant piping are
connected to the outdoor component by means of
the quick-connector system. Once installed, the
connections should be insulated to make them
vapour diffusion proof. The following instructions
describe the installation of the refrigerant piping for
the indoor unit on the outdoor unit.
1.
Remove the pre-installed plastic cover from
the outdoor component (Fig. 32).

2.
Remove the green/black protective caps from
the quick-connectors on the outdoor compo-
nent, as well as the flexible refrigerant pipes
on the indoor unit (Fig. 33 and Fig. 34).

3.
Before connecting the refrigerant pipes,
ensure that the quick-release couplings are
situated in front of one another (Fig. 35).

4.
First connect and hand-tighten the refrigerant
piping to ensure it is correctly seated.
5.
Then install the suction pipe with the largest
diameter (Fig. 36).
NOTICE!
When connecting the refrigerant piping,
take note of the "Outdoor unit, top" and
"Outdoor unit bottom" labelling and not
the colour-coding of the sealing caps.
Note the diameter of the lines. In order to
guarantee the function of the unit, the line
must be connected with other lines of
identical diameter!
