INDOOR UNIT INSTALLATION (Cont.)
13-2 INSTALLATION STEPS OF INDOOR UNIT
Step (1) : Installing wall hang bracket
•
Allow the clearance space around the unit, which
permits adequate air circulation, easy access to the
unit for easy service and maintenance.
•
Fix wall hang bracket on the wall so that it is
leveled vertically and horizontally by using five
self-tapping screws to fix bracket top. 1 (One)
screws to fix bracket mid, 2 (Two) screws to fix
bracket bottom, Use a plumb line if necessary to
adjust leveling of the wall hang bracket.

NOTES
a.
Fasten the wall hang bracket to the wall with at
least 5 (Five) screws ( supplied with unit ).
This correct fixation will prevent motion of bracket
after fixation, which can cause noisy unit
operation.
b. The wall hang bracket must be leveled in both
horizontal and vertical directions after fixation
without tilting to the right or lift to avoid water
dropping from the unit onto the floor. See Fig.
c. Install the wall hang bracket so that three is no
gap between it and the wall to avoid vibrations
and sound during unit operation.
d.
Check that the wall hang bracket does not
move. This can cause noise during operation.
See chapter (18):Connecting Electrical
Wiring.
Step (2): Electrical wiring of indoor unit
Step (3): Form refrigerant piping, drain hose
and electrical cables of indoor unit.
•
As per the selected location of wall hole, form
and tie together with vinyl tape the refrigerant
piping, electrical cables and drain hose to form
a bundle. The drain hose should be at the bottom
of the bundle. Locating the drain hose at the top
of the bundle can cause drain pan to overflow
inside the indoor unit.
NOTES
a. Do not remove the flare nuts from the indoor unit
piping until the piping is ready for connection with
refrigerant piping lines.
b. Do not crush or kink the indoor unit piping.
Avoid tight bending with a bending radius less
than 100 mm.
c. Do not bend the same part of the pipe too often to
avoid pipe damage.
d. Bend pipes carefully to avoid flattening or
obstructing them if the pipes are bent in correctly,
the indoor unit may be unstable on the wall.
e. Carefully arrange pipes so that pipes do not stick
out of the wall hang bracket of the indoor unit.
