10.1. Safety Precautions
 • 
Read the followin g“SAFET Y PRECA UTIONS”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.
 • 
The caution items stated here must be followed because these important contents are related to safety. The meaning of each
indication used is as below.
Incorrect installation due to ignoring of the instruction will cause harm or damage, and the seriousness is classified by the
followin g indications.
This indication shows the possibility of causing death or serious injury.
This indication shows the possibility of causing injury or damage to properties only.
The items to be followed are classified by the symbols:
Symbol with background white denotes item that is PROHIBITE D from doing.
 • 
Carry out test running to confirm that no abnormality occurs after the installation. Then, explain to user the operation, care and
maintenance as stated in instructions. Please remind the customer to keep the operating instructions for future reference.
1.Engage dealer or specialist for installation. If installation done by the user is defective, it will cause water leakage, electrical shock or fire.
2.Install according to this installation instruction strictly. If installation is defective, it will cause water leakage, electrical shock or fire.
3.Use the attached accessories parts and specified parts for installation. Otherwise, it will cause the set to fall, water leakage, fire or
electrical shock.
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 instruction. 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 or fire.
6.Use the specified cable (1.5 mm2) and connect tightly for indoor/outdoor connection. 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.Wire routing must beproperly 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 outpiping 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 damage or use unspecified power supply cord. Otherwise, it will cause fire or electrical shock.
10.Do not modify the length of the power supply cord or use of the extension cord, and do not share the single outlet with
other electrical appliances. Otherwise, it will cause fire or electrical shock.

							1.The equipment must be earthed. 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.
1.Selection of the installation location.
Select a installation location which is rigid and strong enough to support or hold the unit, and select a location for easy maintenance.
2.Power supply connection to the room air conditioner.
Connect the power supply cord of the room air conditioner to the mains using one of the following method.
Power supply point shall be the place where there is ease for access for the power disconnection in case of emergency.
In some countries, permanent connection of this room air conditioner to the power supply is prohibited.
 1. Power supply connection to the receptacle using a power plug.
Use an approved 15A/16A power plug with earth pin for the connection to the socket.
 2. Power supply connection to a circuit breaker for the permanent connection. Use an approved 16A circuit breaker for the permanent
connection. It must be a double pole switch with a minimum 3 mm contact gap.
3.Do not release refrigerant.
Do not release refrigerant during piping work for installation, reinstallation and during repairing a refrigeration parts. Take care of the
liquid refrigerant, it may cause frostbite.
4.Installation work.
It may need two people to carry out the installation work.

SELEC T THE BEST LOCATION
INDOOR UNIT
 • There should not be any heat source or steam near the
unit.
 • There should not be any obstacles blocking the air
circulation.
 • A place where air circulation in the room is good.
 • A place where drainage can be easily done.
 • A place where noise prevention is taken into
conside ration.
 • Do not install the unit near the door way.
 • Ensure the spaces indicate d by arrows from the wall,
ceiling, fence or other obstacles.
 • Recommended installation height for indoor unit shall be
at least 2.3 m.
OUTDOOR UNIT
 • If an awning is built over the unit to prevent direct
sunlight or rain, be careful that heat radiation from the
conden ser is not obstructed.
 • There should not be any animal or plant which could be
affected by hot air discharged.
 • Keep the spaces indicate d by arrows from wall, ceiling,
fence or other obstacles.
 • Do not place any obstacles which may cause a short
circuit of the discharged air.
 • If piping length is over the common length, addition al
refrigerant should be added as shown in the table.
REMOTE CONTROL
 • Do not install at places where there is direct sunlight or
near any heat sourc.

							10.2.1. SELECT THE BEST LOCATION
(Refer to“Select the best location”
section)
10.2.2. HOW TO FIX INSTALLATION
PLATE
The mounting wall is strong and solid enough to prevent itfrom
the vibration.
The centre of installation plate should be at more than 450 mm
at right and left of the wall.
The distance from installation plate edge toceiling should more
than 67 mm.
From installation plate left edge to unit’s left side is 47 mm.
From installation plate right edge to unit’s right is 73 mm.
:
:
:For left side piping, piping connection for liquid should be
about 14 mm from this line.
For left side piping, piping connection for gas should be
about 56 mm from this line.
For left side piping, piping connecting cable should be
about 785 mm from this line.
 1. Mount the installation plate on the wall with 5 screws or
more.
(If mounting the unit on the concrete wall conside r using
anchor bolts.)
 • Alwaysmount the installation plate horizontally by
aligning the marking-off line with the thread and using a
level gauge.
 2. Drill the piping plate hole withø70 mm hole-core drill.
 • Line according to the arrows marked on the lower left
and right side of the installation plate. The meeting point
of the extended line is the centre of the hole. Anothe r
method is by putting measuring tape at position as
shown in the diagram above. The hole centre is
obtaine d by measuring the distance namely 150 mm
and 125 mm for left and right hole respectively.
 • Drill the piping hole at either the right or the left and the
hole should be slightly slanted to the outdoor side.
10.2.3. TO DRILL A HOLE IN THEWALL
AND INSTALL A SLEEVE OF
PIPING
 1. Insert the piping sleeve to the hole.
 2. Fix the bushing to the sleeve.
 3. Cut the sleeve until it extrudes about 15 mm from the wall.
CautionWhen thewall is hollow, please be sure to use the
sleeve for tube ass’y to prevent dangers caused by
mice biting the connecting cable.
 4. Finish by sealing the sleeve with putty or caulking
compound at the final stage.

terminal Nos. are the same to the indoor’s respectively.
 • Earth lead wire shall be longer than the other lead wires
as shown in the figure for the electrical safety in case of
the slipping out of the cord from the anchorage.
 • Secure the cable onto the control board with the holder
(clamper).
HOW TO TAKE OUT FRONT GRILLE
