• Read the follow SAFETY PRECAUTIONS carefully before installation.
• Electrical work must be performed by a licensed electrician. Be sure to use the correct rating of the power
cord and main circuit for the model to be installed.
• Incorrect installation due to ignoring the instruction will cause harm or damage.
n The seriousness is classied by the following indications.
WARNING!
!
CAUTION!
!
The items to be followed are classied by the symbols:
This symbol indicates the possibility of death or serious injury.
This symbol indicates the possibility of injury or damage to property.
This symbol denotes item that is PROHIBITED from doing.
WARNING!
!
1) Do not install without an authorized servicer/installer.
2) Install according to this installation instruction. If installation is defective, it can cause water leakage, or
electrical shock/re.
3) Use the supplied accessories and specied parts for installation.
4) Install the indoor unit on a wall strong enough to hold the unit’s weight. Install the outdoor unit on a
raised concrete pad or blocks to provide a solid, level foundation. In a location with high winds, anchor
the unit and provide an air bafe. In snowy areas (for heat pump models), install the outdoor unit on a
raised platform so that it is higher than drifting snow. Provide snow vents.
5) For electrical work, follow local and national electric codes and these installation instructions. An
independent circuit and single outlet must be used. If electrical circuit capacity is not enough or defects
are found in electrical work, it will cause electrical shock or re.
6) Use the specied cable and connect tightly and clamp the cable so that no external force will stress the
terminal. Loose wiring may cause overheating at the connection points and a possible re hazard.
7) Wiring routing must be properly arranged so that control board cover is xed properly. If control board
cover is not xed perfectly, it will cause overheating at connection point of terminal, re or electrical shock.
8) When charging the unit, take care not to let air/substances other than the specied 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 an extension cord, and do not share the
single outlet with other electrical appliances. Otherwise, it will cause re or electrical shock.
CAUTION!
!
1) This equipment must be grounded and installed with a ground leakage current breaker. It may cause
electrical shock if grounding work doesn’t comply with local/national electric codes.
2) Do not install the unit at place where leakage of ammable gas may occur. If gas leaks and
accumulates near the unit, it may cause re.
3) Carry out drainage piping as mentioned in installation instructions. If not done correctly, water may
enter the room and damage personal belongings.

1. Wall-mounted type
Selecting installation place
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 nder to locate studs to prevent unnecessary damage to the wall.
• The indoor unit should be installed on the wall at a height of 6.5ft.(2m) or more from the oor.
• The indoor unit should be installed allowing a minimum clearance of 6in.(15cm) from the ceiling.
• Any variations in pipe length may require adjustment to refrigerant charge.
• Do not expose unit to direct sunlight. The sun will fade the plastic cabinet and affect its appearance.
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.
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 considered a non-serviceable installation.
