Installing 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 as 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 make them
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 height of the installed location should be 8ft
or more from the floor.
