Purging the Unit
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.
Connecting the Assembly Cable
The outdoor unit is powered from the indoor unit via the assembly cable.
If the outdoor unit is more than 5m (16ft. 5in) away from the indoor unit,
the cable must first be extended to a maximum of 20m (65ft. 7in).
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; if necessary, refer to page 23.
3
Remove the screw securing the connector cover, then open the connector
cover.
4
Remove screws (4EA) securing the front panel, then detach the front panel
from the indoor unit.
