4-4-6. Purging the Unit
On delivery, the indoor unit is loaded with an inert
nitrogen 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.
Note : 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.
4-4-7. Connecting the Connection Cord
The indoor unit is powered from the outdoor unit via the
connection cord.
1. Remove the screw on the electrical component
box and remove the cover plate.
2. Route the connection cord through the side of
the indoor unit and connect the cable to
terminals.
Note : When connecting the cables, you must pass
them through the cable clamp to fix them
securely.
3. Route the other end of the cable to the outdoor
unit through the ceiling & the hole on the wall.
4. Reassemble the electrical component box cover,
carefully tightening the screw.
