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:
Tube diameter Tightening torque,approximate(N·m)
Ф 6.35(1/4") 14 ~ 18 N·m(140-180kgf.cm)
Ф 9.52(3/8")
34 ~ 42 N·m(340-420kgf.cm)
Ф 12.7(1/2") 49 ~ 61 N·m(490-610kgf.cm)
Ф 15.88(5/8") 68 ~ 82 N·m(680-820kgf.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 may cause leakage.
