Make sure that all wiring connections are secure and the cover
plates are reinstalled properly. Poor installation may cause fire
or electric shock.
Installation of Indoor Unit
•
The piping can be output from right, right rear, left or
left rear.
1. 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.1)
a. Cut off the tailings 1 when routing the wiring only;
b. Cut off the tailings 1 and tailings 2 when routing both the
wiring and piping.
2. 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.2)
