INSTALLATION
PROCEDURE
INDOOR UNIT
■Fixing
•Place the installation guide pattern on the designated
installation place and mark the hole position.
•Drill a hole and mount installation plate.
•After determining the pipe
hole position. Drill the hole
at a slight downward slant
towards the outdoor side.
Note : When installing
the refrigerant pipes from
others side. A hole must
be place to allow fall
towards the outdoor unit.
•Make ø5mm.4-6 holes, in the wall at the four corners
of mouting plate (bracket) then insert appropriate
mouting devices.
•Install the mounting plate using 4-6 pieces of mounting
screw securely at four corners and tighten the screw
completely.Do not over tighten the screws and deform
the back plate.
Caution
•Be careful when handling the sharp edge of the
mounting plate.
■Wiring
•This indoor unit is ready for connection to the outdoor
unit.
Cautions
•Never modify the unit by removing any of the safety
guards or by bypassing any of the safety interlock
swithces.
•Connect the interconnecting cable correctly and
connect the connecting cable to terminal as identified
with their respective marking.
•Do not damage the conductor core or inner insulation
of power supply cables and do not deform or crush
the cables.
■Piping
The auxiliary piping can be connected in the diections
shown the above diagram.To connect in the D, E and F
direction, pipes will need to be extended.
Cautions
•Bend pipes carefully to avoid flattening or obstructing
them if the pipes are bent incorrectly, the indoor unit
may be unstable on the wall.
•Carefully arrange pipes so that pipes do not stick out
of the rear plate of the indoor unit.

trap (U bend).Connect a plastic condensate pipe with
an internal diameter of 12 mm.
Note: Do not put the drain hose end into water.
• The drain hose can be connected to the left or the
right side.
For left and left rear piping
For left and left rear piping
Verification of condensate water drainage:
Fill the drain pan with water and observe evacuation.
■Indoor Unit Fixing
• Thread the indoor unit piping and cable through the
hole.
• Hang the top of the unit onto the upper ridge of them
in mounting plate.
• Make sure that the unit is correctly hung in place by
sliding it to the left, then to the right.
• Press the bottom left and bottom right hand corners of
the unit against the mounting plate until the fixing
prongs click into place in the retainers provided to that
effect.
