On delivery, the indoor unit is loaded with an inert gas. All this gas
must therefore be purged before connecting the assembly piping.
To purge the inert gas, proceed as follows.
Unscrew the caps at the end of each pipe.
Result: All inert gas escapes from the indoor unit.
➢
To prevent dirt or foreign objects from getting into the pipes
during installation, do NOT remove the caps completely
until you are ready to connect the piping.
The outdoor unit is powered from the indoor unit via the assembly
cable. If the outdoor unit is more than 5 metres away from the indoor
unit, the cable must first be extended to a maximum of 15 metres.
1 Extend the assembly cable if necessary.
2 Open the front grille by pulling on the tabs on the lower right and left sides
of the indoor unit.
3 Remove the screw securing the connector cover.
4 Pass the assembly cable through the rear of the indoor unit and connect the
assembly cable to terminals.
➢ Each wire is labelled with the corresponding terminal number.
5 Pass the other end of the cable through the 65 mm hole in the wall.
6 Replace the connector cover, carefully tightening the screw.
7 Close the front grille.
8 For further details on how to plug the other end of the assembly cable into
the outdoor unit, refer to page 36.
