INSTALLATION OF THE INDOOR UNIT
Mounting Installation Plate
Ensure that the wall is strong enough to withstand the weight
of the unit. Otherwise, it is necessary to reinforce the wall
with plates, beams or pillars.
Use the level gauge for horizontal mounting, and fix it with
4 suitable screws.
In case the rear piping draws out, drill a hole 65mm in
diameter with a cone drill, slightly lower on the outside wall
(see figure).
Mount The Unit Onto The Installation Plate
Hook the indoor unit onto the upper portion of the
installation plate (Engage the two hooks at the rear top of
the indoor unit with the upper edge of the installation plate).
Ensure that the hooks are properly seated on the
installation plate by moving it to the left and right.
Water Drainage Piping
The indoor drain pipe must be in a downward gradient for
smooth drainage. Avoid situations that are likely to cause
water to leak.

The indoor unit must be installed in such a way so as to
prevent short circuit of the cool discharged air with the hot
return air. Please follow the installation clearance shown in
the figure. Do not place the indoor unit where there could be
direct sunlight shining on it. Also, this location must be
suitable for piping and drainage, and be away from doors or
windows.

The refrigerant piping can be routed to the unit in a
number of ways (left or right from the back of the unit), by
using the cut-out holes on the casing of the unit (see figure).
Bend the pipes carefully to the required position in order to
aligned it with the holes. For the right hand and rear side
out, hold the bottom of the piping and then position it to the
required direction (see figure). The condensation drain hose
can be taped to the pipes.
