1-4. INSTALLATION DIAGRAM
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 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 ø65 mm hole. The outdoor side should be 5 to 7
mm lower than the indoor side.
3) Insert wall hole sleeve (C).
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 process
the end of the wire.
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.

and to prevent damage by
rodents in case the wall

After the leak test, apply
insulating material tightly so
that there is no gap.
When the piping is to be
attached 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 vinyl 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.

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.
* Note:
Place indoor/outdoor unit connecting wire (A) and
power supply cord (K) at least 1 m away from the
TV antenna wire.
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 corre-
spondent terminal when securing the cord
and/or the wire to the terminal block.
Note:
Do not place the wires between the
indoor unit and the installation plate (1).
Damaged wire could cause heat genera-
tion or fire.
