Outdoor Unit

Fix the unit to concrete or block with bolts( 10mm) and nuts firmly and horizontally.
When fitting the unit to wall surface, roof or rooftop, fix a supporter surely with nails

or wires in consideration of earthquake and strong wind.
If vibration may affect the house, fix the unit by attaching a vibration-proof mat.

Place, robust not causing vibration, where the body can be supported
sufficiently.
Place, not affected by heat or steam generated in the vicinity, where
inlet and outlet of the unit are not disturbed.
Place, possible to drain easily, where piping can be connected with the
outdoor unit.
Place, where cold air can be spread in a room entirely.
Place, nearby a power receptacle, with enough space around. (Refer
to drawings).
Place where the distance of more than lm from televisions, radios,
wireless apparatuses and fluorescent lamps can be left.
In the case of fixing the remote controller on a wall, place where the
indoor unit can receive signals when the fluorescent lamps in the room
are lightened.

Place, which is less affected by rain or direct sunlight and is
sufficiently ventilated.
Place, possible to bear the unit, where vibration and noise are
not increased.
Place, where discharged wind and noise do not cause a
nuisance to the neighbors.
Place, where a distance marked is available as illustrated
in the above figure.

Before inserting power plug into receptacle, check the voltage without fail. The power source is the same as the corresponding name plate.
Install an exclusive branch circuit of the power.
A receptacle shall be set up in a distance where the power cable can be reached. Do not extend the cable by cutting it.

To this unit, both liquid and gas pipes shall be insulated
as they become Iow temperature in operation.
Use optional parts for piping set or pipes covered with
equivalent insulation material.
The thickness of the pipe must be 0.8 mm at least.

1.Fitting of the Mounting Plate and Positioning of the wall Hole
When the mounting plate is first fixed

1.Carry out, based on the neighboring pillars or lintels, a proper leveling for the plate to be
fixed against the wall, then temporarily fasten the plate with one steel nail.

2. Make sure once more the proper level of the plate, by hanging a thread with a weight from
the central top of the plate, then fasten securely the plate with the attachment steel nail.

3. Find the wall hole location A using a measuring tape

2.Making a Hole on the Wall and Fitting the Piping Hole Cover

Make a hole of 70 mm in diameter,
slightly descending to outside the wall.
Install piping hole cover and seal it
off with putty after installation

When the mounting plate is fixed side bar and lintel

Refer to the previous article, " When the mounting plate is first fixed ", for the
position of wall hole.

Fix to side bar and lintel a mounting bar, Which is separately sold, and then fasten
the plate to the fixed mounting bar.

3.Installation of the Indoor Unit
Drawing of pipe

[ Rear piping ]

Draw pipes and the drain hose, then fasten them with the adhesive tape

[ Left Left-rear piping ]

In case of left side piping, cut away, with a nipper, the lid for left piping.
In case of left-rear piping, bend the pipes according to the piping direction to the mark of hole for left-rear
piping which is marked on heat insulation materials.

Fixing the indoor unit body

Removing the wiring cover

[Other direction piping]

Indoor/outdoor electric cable and drain hose must be bound with refrigerant piping by protecting tape.

Cut away, with a nipper, the lid for piping according to the piping direction and then bend the pipe according
to the position of wall hole. When bending, be careful not to crash pipes.
Connect beforehand the indoor/outdoor electric cable, and then pull out the connected to the heat insulation
of connecting part specially.

Hang surely the unit body onto the upper notches of the
mounting plate. Move the body from side to side to verify
its secure fixing.
In order to fix the body onto the mounting plate,hold up
the body aslant from the underside and then put it down
perpendicularly.

Remove terminal cover at right bottom corner of indoor unit, then
take off wiring cover by removing its screws.

When connecting the cable after installing the indoor unit

1. Insert from outside the room cable into left side of the wall hole, in which
the pipe has already existed.

2. Pull out the cable on the front side, and connect the cable making a loop.

[Cautions]

1.Make sure it is unit A or unit B, when make wiring.

2.Unit to be connected to stop valve A on outdoor unit is unit A,while the one to
be connected to stop valve B is unit B.

3.Refer to wiring diagram.

1. Insert the drain hose into the dent of heat insulation materials of indoor unit.

2. Insert the indoor/outdoor electric cable from backside of indoor unit, and pull it out on the front side, then
connect them.

3. Coat the flaring seal face with refrigerant oil and connect pipes.
Cover the connection part with heat insulation materials closely, and make sure fixing with adhesive tape
