1-4. Type of Copper Tube and Insulation Material
Use insulated copper wire for field wiring. Wire size
varies with the total length of wiring. Refer to 3-6. Wiring
Instructions for details.
If you wish to purchase these materials separately from a
local source, you will need:
1. Deoxidized annealed copper tube for refrigerant tub-
ing as detailed in Table 2.
Check local electrical codes
CAUTION
and regulations before obtain-
ing wire. Also, check any spec-
ified instructions or limitations.
When cutting tubing, add approximately 1' to 1'4" to
each tube length to reduce vibration between the air
conditioning units.

Tubing can be extended in 3 directions as shown in
Fig. 7a. Select the direction you need providing the
shortest run to the outside unit.

(1) Remove the rear panel from the indoor unit and
place it on the wall at the location selected. Make
sure the unit is horizontal, using a carpenter’s level
or tape measure to measure down from the ceiling.

(2) Determine which side of the unit you should make
the hole. (Fig. 7b)

(3) Before making a hole, check carefully that no studs
or pipes are directly run behind the spot to be cut.
In case of left-rear or right-rear tubing
Also avoid areas where electri-

Be sure to confirm that the wall is strong enough to sus-
pend the unit.
See either Item a) or b) below depending on the wall
type.
a) If Wooden Wall
Fig. 11
(1) Attach the rear panel to the wall with the 10 screws
provided. (Fig. 11)
If you are not able to line up the holes in the rear
panel with the beam locations marked on the wall,
use toggle bolts to go through the holes on the panel
or drill 3/16 inch dia. holes in the panel over the stud
locations and then mount the rear panel.
Fig. 12
(2) Double check with a ruler or carpenter’s level that
the panel is level. This is important to install the unit
properly. (Fig. 12)
1-3/16 inches or more
(3) Make sure the panel is flush against the wall. Any
space between the wall and unit will cause noise and
vibration.

3-4. Remove the Grille to Install the Indoor Unit
Basically, these models can be installed and wired with-
out removing the grille. If access to any internal part is
needed, follow the steps as given below:
Grille
Air intake grille
How to remove the grille
(1) Set the 2 flaps in the horizontal position.
(2) Unscrew the 3 screws. (Fig. 14a)
(3) Remove the grille.
(a) Hold both corners of the air intake grille, then pull
out and up to open. (Fig. 14b)
Fig. 14a
(b) Use a standard screwdriver to push up the 3 tabs
to remove the grille. (Fig. 14b)
Air intake grille
(c) Pull the lower part of the grille toward you to
remove. (Fig. 14a)
Fig. 14b

How to replace the grille
(1) Close the flaps.
(2) Reinstall the grille into the lower part while aligning
its tabs on the upper part. (Fig. 15a) Insert the tabs
in the slots and push the lower part of the grille back
into position.
Fig. 15a
(3) Press at each of the 5 tabs to completely close the
grille. Make sure that the grille and frame are firmly
fitted together. (Fig. 15b)
3-5. Shape the Indoor Side Tubing
1) Arrangement of tubing by directions
a) Right tubing
The corner of right frame needs to be cut by a
hacksaw or the like. (Fig. 16)

Fig. 16
General precautions on wiring
Tab
Mounting slot
1) Before wiring, confirm the rated voltage of the unit as
shown on its nameplate, then carry out the wiring
closely following the wiring diagram.
2) Provide a power outlet to be used exclusively for
each unit, with a power supply disconnect and circuit
breaker for overcurrent protection provided in the
exclusive line.
Fig. 17
3) To prevent possible hazard due to insulation failure,
the unit must be grounded.
4) Each wiring connection must be done tightly and in
accordance with the wiring system diagram. Wrong
wiring may cause the unit to misoperate or become
damaged.
5) Do not allow wiring to touch the refrigerant tubing,
compressor, or any moving parts of the fan.
6) Unauthorized changes in the internal wiring can be
very dangerous. The manufacturer will accept no
responsibility for any damage or misoperation that
occurs as a result of such unauthorized changes.

3-7. Recommended Wire Length and Diameter
Regulations on wiring diameter differ from locality to
locality. For field wiring requirements, please refer to
your local electrical codes. Carefully observe these regu-
lations when carrying out the installation.
Table 5 lists recommended wire lengths and diameters
for power supply systems.
Refer to the wiring system diagram (Fig. 18) for the
meaning of “A” and “B” in Table 5.

The remote control unit can be operated from either a
non-fixed position or a wall-mounted position.
To ensure that the air conditioner operates correctly, do
not install the remote control unit in the following places:
G In direct sunlight
G Behind a curtain or other place where it is covered
G More than 26 ft. (8 m) away from the air conditioner
G In the path of the air conditioner’s airstream
G Where it may become extremely hot or cold
G Where it may be subject to electrical or magnetic
interference
