Installation of Indoor Unit
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.7)
(1) Cut off tailing 1 when routing the wiring only;
(2) Cut off tailing 1 and tailing 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.8)
3. 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)
4. The installation site should be 250cm or more above the floor.

1. Align the center of the pipe flare with the related valve.
2. Screw in the flare nut by hand and then tighten the nut with
spanner and torque wrench by referring to the following:
Indoor unit piping

14 ~ 18 N·m (140-180 kgf.cm)
Ф 6.35 (1/4”)
Ф 9.52 (3/8”)
34 ~ 42 N·m (340-420 kgf.cm)

NOTE: Connect the connection pipe to indoor unit at first and then to outdoor unit. Handle piping bending
with care. Do not damage the connection pipe. Ensure that the joint nut is tightened firmly, otherwise, it
