Connecting the refrigerant lines
Bby customer on-site connecting the refrigerant lines are at a corner of the unit within the false ceiling. It may
be necessary to fit a reducing or extending adapter to the indoor units. These fittings are included with the
indoor unit as an accessory kit. Once installed, the connections should be sealed to prevent vapour diffusion.

NOTICE!
Only one adjacent room connection and one
fresh air connection may be used!
NOTICE!
The unit is factory filled with dry nitrogen for
leak testing purposes. The pressurised
nitrogen is released when the union nuts are
undone.
Installation instructions
To install the fresh air connection and the connec-
tion for the adjacent room, proceed as follows:
1. Remember that directly behind the insulation
to be removed are the plate fins of the hea-
texchanger and that these may by no means
be damaged (Fig. 30).
2. Carefully remove the insulation behind the
opening. (Fig. 31).
3. Break through the corresponding openings
(Fig. 32).
4. Keep the vent pipe as short as possible and
lay it with as few bends as necessary.
5. Keep in mind that the flanged collar, screws,
flexible/folded spiral-seam pipes and insula-
tion materials must be provided by the cus-
tomer. These parts can all be purchased
from your dealer. (Fig. 33).
