SAFETY PRECAUTIONS
WARNING
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.
This symbol indicates the possibility of death or serious injury.
The items to be followed are classified by the symbols:
Symbol with background white denotes item that is PROHIBITED from doing.
CAUTION
This symbol indicates the possibility of injury or damage to property.
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.

Read completely, 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 5in.(12cm).
Use a stud finder to locate studs to prevent unnecessary damage to the wall.
The indoor unit should be installed on the wall at a height of 6 3/5ft.(2m) or more from the floor.
The indoor unit should be installed allowing a minimum clearance of 6in.(15cm) from the ceiling.
Any variations in pipe length will/may require adjustment to refrigerant charge.
There should not be any direct sunlight. Otherwise, the sun will fade the plastic cabinet and
affect its appearance. If unavoidable, sunlight prevention should be taken into consideration.
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 12in.(30cm) and left
side is more than 12in.(30cm). The front of the
unit should have more than 79in.(200cm) of
clearance and the connection side (right side)
should have more than 24in.(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 neighbors.
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.
