UNITS INSTALLATION
10-11
(The plug can be secured diagonally with a screw as
shown above.)
WARNING
• Be sure to attach screw to prevent the indoor unit
from overturn.
2. Wall installation
Direct mounting on the wall
• Please remove 3 screws and clip which fix to the
stand and cabinet. (As shown in the figure below)
• Please remove the screws which fix the cabinet
and hanger.
• Please use hidden beams in the wall to hold the
hanger.
CAUTION
• The draining of the water container inside the
indoor unit can be done from the left. Therefore the
hanger must be fixed horizontally or slightly tilted
towards the side of drain hose. Otherwise,
condensed water may overflor the water container.
Procedure of installation and precautions.
Procedure to fix the hanger and indoor unit.
1. Drill holes on wall (As
shown below)
2. Push plug into the holes
(As shown below)
3. Fix the hanger on wall with 4.1x32 and 4.0x34 screw.
(As shown in figure below)
4. Fix the indoor unit on the wall with 4.1x32 screw.
3. Built-in installation
• If outlet is covered with the lattice door, room
temperature may not be controlled properly. Therefore,
air outlet must be open as much as possible.
• If air deflector of air outlet is adjusted too much
upward, room temperature may not be controlled
properly due to the heat inside the lattice door.
Therefore, the deflector must be adjusted to nearly
horizontal angle.
• If signal receiver is covered with the lattice door,
signal receiving distance or range (angle) becomes
smaller. Therefore, single receiver must not be
covered with the lattice door.
• Only the vertical lattice door may be used. Besure to
use a lattice door with an open area ratio of 75% or
more. If another lattice door or one with an open area
ratio of less than 75% is used, maximum performance
may not be obtained.
• With a built-in installation, it may take more time to
reach the set temperature after the unit is switched on.
1. Drill holes on floor
2. Push plug into the holes.
