2-1. FIXING OF INSTALLATION PLATE
• Find a structural material (such as a stud) in the wall and fix installation plate (1) hori-
zontally by tightening the fixing screws (2) firmly.
• To prevent installation plate (1) from vibrating, be sure to install the fixing screws in
the holes indicated in the illustration. For added support, fixing screws may also be
installed in other holes.
• When the knockout is removed, apply vinyl tape to the knockout edges to prevent
damaging the wires.
• When bolts recessed in the concrete wall are to be utilized, secure installation plate (1)
using 11 × 20 · 11 × 26 oval hole (450 mm pitch).
• If the recessed bolt is too long, change it for a shorter one available in the market.
2-2. WALL HOLE DRILLING
1) Determine the wall hole position.
2) Drill a ø 75 mm hole. The outdoor side should be
5 to 7 mm lower than the indoor side.
3) Insert wall hole sleeve (C).

Units should be installed by licensed contractor
according to local code requirements.

Be sure to use wall hole
sleeve (C) to prevent
indoor/outdoor connecting
wire (A) from contacting
metal parts in the wall and
to prevent damage by
rodents in case the wall is
hollow.

After the leak test, apply
insulating material tightly
so that there is no gap.
When the piping is to be at-
tached to a wall containing
metals (tin plated) or metal
netting, use a chemically
treated wooden piece 20
mm or thicker between the
wall and the piping or wrap
7 to 8 turns of insulation vi-
nyl tape around the piping.
To use existing piping, per-
form COOL operation for
30 minutes and pump down
before removing the old air
conditioner. Remake flare
according to the dimension
for new refrigerant.
Appearance of the outdoor unit may differ from some
models.

• For future servicing, give extra length to the
connecting wires.
• Make earth wire a little longer than others. (More
than 60 mm)
• Do not fold the excess wire, or cram it into small
space. Take caution not to damage the wires.
• Be sure to attach each screw to its correspond-
ent terminal when securing the cord and/or the
wire to the terminal block.
Note:
Do not place the wires between the in-
door unit and the installation plate (1). Damaged
wire could cause heat generation or fire.

4) Loosen terminal screw, and connect first the earth wire, then indoor/outdoor unit con-
necting wire (A) to the terminal block. Be careful not to make mis-wiring. Fix the wire
to the terminal block securely so that no part of its core is appeared, and no external
force is conveyed to the connecting section of the terminal block.
5) Firmly tighten the terminal screws to prevent them from loosening. After tightening, pull
the wires lightly to confirm that they do not move.
6) Secure indoor/outdoor unit connecting wire (A) and the earth wire with the VA clamp.
Never fail to hook the left claw of the VA clamp. Attach the VA clamp securely.

Drain piping for outdoor unit
• Provide drain piping before indoor and
outdoor piping connection.
• Connect drain hose (I) I.D.15 mm as
shown in the illustration.
• Make sure to provide drain piping with
a downhill grade for easy drain flow.

Note:
Install the unit horizontally.
Do not use drain socket (8) in cold regions. Drain may freeze and
make the fan stop.
The outdoor unit produces condensate during the heating operation.
Select the installation place to ensure to prevent the outdoor unit
and/or the grounds from being wet by drain water or damaged by
frozen drain water.
2-3. CONNECTING WIRES FOR INDOOR UNIT
You can connect indoor/outdoor lead wire without removing the front panel.
1) Open the front panel.
2) Remove VA clamp.
3) Pass indoor/outdoor unit connecting wire (A) from the back of the indoor unit and proc-
ess the end of the wire.
2-4. PIPE FORMING AND DRAIN PIPING
Pipe Forming
• Place the drain hose below the refrigerant piping.
• Make sure that the drain hose is not heaved or snaked.
• Do not pull the hose when applying the tape.
• When the drain hose passes the room, be sure to wrap
insulation material (obtainable at a store) around it.
