SAFETY PRECAUTIONS
The following should be always observed for safety:
•Be sure to read the following WARNING before installing the air conditioner.
•Be sure to observe the cautions specified here as they include important items related to
safety.
•After reading this instructions, be sure to keep it together with the owners manual in a
handy place for future reference.
Do not install it yourself. Perform the installation securely referring to
the installation instruction.
•Incorrect installation could cause injury due to
fire, electric shock, the unit falling or leakage of
water. Consult the dealer from whom you
purchased the unit or special installer.
•Incorrect installation could cause injury due to
fire, electric shock, the unit falling or leakage of
water.
Install the unit securely in a place which can
bear the weight of the unit. Perform electrical work according to the installation manual and be sure to use an
exclusive circuit.
•When installed in an insufficiently strong place,
the unit could fall causing injury. •If the capacity of the power circuit is insufficient or there is incomplete electrical work, it could
result in a fire or an electric shock.
Use the specified wires to connect the indoor
and outdoor units securely and attach the
wires firmly to the terminal board connecting
sections so the stress of the wires is not
applied to the sections
Check that the refrigerant gas does not leak
after installation is completed.
•Incorrect connection and fixing could cause a
fire.
Be sure to use the part provided or specified
parts for the installation work. Attach the electrical part cover to the indoor unit and the service panel to the outdoor unit
securely.
•The use of defective parts could cause an injury
due to a fire, electric shock, the unit falling, etc. If the electrical part covers of the indoor unit
and/or the service panel of the outdoor unit are
not attached securely, it could result in a fire or
electrical shock due to dust, water, etc.
Do not install the unit in a place where a
flammable gas leaks. Perform the drainage/piping work according to the installation instruction.
•If gas leaks and accumulates in the area
surrounding the unit, it could cause a explosion.
•If there is a defect in the drainage/piping work,
water could leak from the unit and household
goods could get wet and be damaged.

INSTALLATION OF INDOOR UNIT AND OUTDOOR UNIT
Read completely, and then follow step by step.
Indoor unit
•Do not expose the indoor unit to heat or steam.
•Select a place where there are no obstacles in front or
around the unit.
•Make sure that condensation drainage can be
conveniently routed away.
•Do not install near a doorway.
•Ensure that the space on the left and right of the unit is more than 12cm.
•Use a stud finder to locate studs to prevent unnecessary damage to the wall.
•A minimum pipe run of 3 metres is required to minimise vibration & excessive noise.
•The indoor unit should be installed on the wall at a height of 2.3 metres or more from the
floor.
•The indoor unit should be installed allowing a minimum clearance of 15cm from the
ceiling.
•Any variations in pipe length will/may require adjustment to refrigerant charge.
Outdoor unit
•If an awning is built over the outdoor unit to
prevent direct sunlight or rain exposure, make
sure that heat radiation from the condenser is
not restricted.
•Ensure that the clearance around the back of
the unit is more than 30cm and left side is more
than 30cm. The front of the unit should have
more than 200cm of clearance and the
connection side (right side) should have more than 60cm of clearance.
•Do not place animals and plants in the path of the air inlet or outlet.
•Take the air conditioner weight into account and select a place where noise and vibration
will not be an issue.
•Select a place so that the warm air and noise from the air conditioner do not disturb
neighbours.
Rooftop installation:
•If the outdoor unit is installed on a roof structure, be sure to level the unit. Ensure the roof
structure and anchoring method are adequate for the unit location.
•Consult local codes regarding rooftop mounting.
•If the outdoor unit is installed on roof structures or external walls, this may result in
excessive noise and vibration, and may also be classed as a non serviceable installation.

5 Installation instructions
INDOOR UNIT INSTALLATION
1. Fit the Installation Plate
1. Fit the installation plate horizontally on
structural parts of the wall with spaces
around the installation plate.
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:
Fit the Installation Plate and drill holes in the wall according to the wall structure and
corresponding mounting points on the installation plate.
(Dimensions are in “mm” unless otherwise stated).
2. Drill a hole in the wall
1. Determine hole positions according to the diagram
detailed in Fig.5. Drill one (1) hole (Φ65mm) 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
below.
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.
Connective pipe
1. For the left-hand and right-hand piping, remove the pipe cover from the side panel.
•Explain to clients that the pipe cover must be kept as it may be used when relocate the
air conditioner to any other place.
2. For the rear-right-hand and rear-left-hand piping, install the piping as shown. 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. Indoor unit installation
1.Pass the piping through the hole in the 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.
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 from side to
side, up and down to check if it is hooked
securely.

5. Piping and wrapping
Bundle the tubing, connecting cable,
anddrain hose with tape securely, evenly
as shown in Fig.10.
•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.
OUTDOOR UNIT INSTALLATION
Outdoor installation precaution
•Install the outdoor unit on a rigid base to prevent increasing noise level and vibration.
•Determine the air outlet direction where the discharged air is not blocked.
•In the case that the installation place is exposed to strong wind such as a seaside, make
sure the fan operating properly by putting the unit lengthwise along the wall or using a
dust or shield plates.
•Specially in windy area, install the unit to prevent the admission of wind.
•If need suspending installation, the installation bracket should accord with technique
requirement in the installation bracket
diagram. The installation wall should be solid
brick, concrete or the same intensity
construction, or actions to reinforce, damping
supporting should be taken. The connection
between bracket and wall, bracket and the air
conditioner should be firm, stable and reliable.
•Be sure there is no obstacles which block
radiating air.
