SAFETY PRECAUTIONS

Read the follow SAFETY PRECAUTIONS carefully before installation.
Electrical work must be installed by a licensed electrician. Be sure to use the correct rating
of the power plug and main circuit for the model to be installed.
Incorrect installation due to ignoring of the instruction will cause harm or damage.
The seriousness is classified by the following indications.

WARNING

CAUTION

This symbol indicates the possibility of death or serious injury.

This symbol indicates the possibility of injury or damage to property.

The items to be followed are classified by the symbols:

Symbol with background white denotes item that is PROHIBITED from doing.

WARNING

1) Engage dealer or specialist for installation. If installation done by the user is defective, it will cause water
leakage, electrical shock fire.

2) Install according to this installation instructions strictly. If installation is defective, it will cause water
leakage, electrical shock fire.

3) Use the attached accessories parts and specified parts for installation. otherwise, it will cause the set to fall,
water leakage, electrical shock fire.

4) Install at a strong and firm location which is able to withstand the set s weight. If the strength is not enough
or installation is not properly done, the set will drop and cause injury.

5) For electrical work, follow the local national wiring standard, regulation and this installation instructions. An
independent circuit and single outlet must be used. If electrical circuit capacity is not enough or defect found
in electrical work, it will cause electrical shock fire.

6) Use the specified cable and connect tightly and clamp the cable so that no external force will be acted on
the terminal. If connection or fixing is not perfect, it will cause heat-up or fire at the connection.

7) Wiring routing must be properly arranged so that control board cover is fixed properly. If control board cover
is not fixed perfectly, it will cause heat-up at connection point of terminal, fire or electrical shock.

8) When carrying out piping connection, take care not to let air substances other than the specified
refrigerant go into refrigeration cycle. Otherwise, it will cause lower capacity, abnormal high pressure
in the refrigeration cycle, explosion and injury.

9) Do not modify the length of the power supply cord or use of extension cord, and do not share the
single outlet with other electrical appliances. Otherwise, it will cause fire or electrical shock.

,

CAUTION

1) This equipment must be earthed and installed with earth leakage current breaker. It may cause electrical
shock if grounding is not perfect.

2) Do not install the unit at place where leakage of flammable gas may occur. In case gas leaks and
accumulates at surrounding of the unit, it may cause fire.

3) Carry out drainage piping as mentioned in installation instructions. If drainage is not perfect, water
may enter the room and damage the furniture.

2. If the wall is made of brick, concrete
or the like, drill eight (8) 5mm diameter
holes in the wall.Insert Clip anchor for
appropriate mounting screws.

3. Fit the installation plate on the wall
with eight (8) type “A” screws.

Note:

to the diagramdetailed in Fig.5. Drill
one (1) hole ( 65mm) slanting slightly
to outdoor side.

2. Always use wall hole conduit when
drilling metal grid, metal plate or the like.

3. Connective Pipe and Drainage
Installation

Drainage

1. Run the drain hose sloping downward.
Do not install the drain hose as
illustrated in Fig.7.

Do not block water flow by a rise.

2. When connecting extension drain hose,
insulate the connecting part of extension
drain hose with a shield pipe, do not let
the drain hose slack.

INSTALLATION INSTRUCTIONS

Connective pipe installation

1. For the left-hand and right-hand piping,
remove the pipe cover from the side
panel.

2. For the rear-right-hand and rear-left-hand
piping, install the piping as shown in Fig.9.
Bend the connective pipe to be laid at 43mm
height or less from the wall.

3. Fix the end of the connective pipe. (Refer
to Tightening Connection in REFRIGERANT
PIPING CONNECTION)

4. Piping and wrapping

Bundle the tubing, connecting cable, and drain
hose with tape securely, evenly as shown in
Fig.11.
Because the condensed water from rear of the
indoor unit is gathered in ponding box and is
piped out of room. Do not put anything else in
the box.

CAUTION

Connect the indoor unit first, then the
outdoor unit.
Do not allow the piping to let out from
the back of the indoor unit.
Be careful not to let the drain hose slack.
Heat insulated both of the auxiliary piping.
Be sure that the drain hose is located at
the lowest side of the bundle. Locating
at the upper side can cause drain pan
to overflow inside the unit.
Never intercross nor intertwist the power
wire with any other wiring.
Run the drain hose sloped downward to
drain out the condensed water smoothly.

wall.

2. Put the upper claw at the back of the
indoor unit on the upper hook of the
installation plate, move the indoor unit
from side to side to see that it is securely
hooked (see Fig.12).

3. Piping can easily be made by lifting the
indoor unit with a cushioning material
between the indoor unit and the wall.
Get it out after finish piping.

4. Push the lower part of the indoor unit up
on the wall, then move the indoor unit

Notes before installation

1. Decide the correct carry-in path.

2. Move this unit as originally packaged as possible.

3. If the air conditioner is installed on a metal part
of the building, it must be electrically insulated
according to the relevant electrical code.

4. If installing in a lonely building or at a high position
where it is hot and humid with frequent thunder­ storm, lightning-protection equipment is necessary.

Indoor unit installation

1. Install the main body

A. The existing ceiling (to be horizontal)
a. Please cut a quadrangular hole of 600 600mm
in the ceiling according to the shape of the
installation paper board. (Refer to Fig.15 & 16)
The center of the hole should be at the same
position of that of the air conditioner body.
Determine the lengths and outlets of the conn­ ecting pipe, drain pipe and cables.
To balance the ceiling and to avoid vibration,
please enforce the ceiling when necessary.
b. Please select the position of installation hooks
according to the hook holes on the installation
board.
Drill four holes of 12mm, 50~55mm deep at the
selected positions on the ceiling. Then embed
the expansible hooks(fittings).
Face the concave side of the installation hooks
toward the expansible hooks. Determine the
length of the installation hooks from the height
of ceiling, then cut off the unnecessary part.
If the ceiling is extremely high, please determine
the length of the installation hook according to
facts.
Cut the installation hook open in the middle
position, then use apropriate length of reinforcing
rod ( 12) to weld together.
