Installation of Indoor Unit
The piping can be output from right, right rear, left
or left rear.
When routing the piping and wiring from the left
or right side of indoor unit, cut off the tailings
from the chassis when necessary(As shown in Fig.7)
Cut off the tailings 1 when routing the wiring only;
Cut off the tailings 1 and tailings 2 when routing
both the wiring and piping.
Take out the piping from body case, wrap the piping,
power cords, drain hose with the tape and then make
them pass through the piping hole. (As shown in Fig.8)
Hang the mounting slots of the indoor unit on the
upper hooks of the mounting plate and check if it is
firm enough.(As shown in Fig.9)
The installation site should be 250cm or more above
the floor.
Installation of Connection Pipe

Screw in the flare nut by hand and then tighten the
nut with spanner and torque wrench by referring to the
following:
NOTE: Connect the connection pipe to indoor unit at first and then to outdoor unit.
