• 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 classied by the following indications.
WARNING!
!
CAUTION!
!
The items to be followed are classied 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 specied 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 bafe. In snowy areas (for heat pump models), install the outdoor unit on a raised platform 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 specied cable and connect tightly. Clamp the cable so that no external force will stress the connections. Loose wiring may overheat at the connection points and create 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 specied 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 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.

Selecting installation place
Choose a location that places the outdoor unit as close to the indoor unit as possible. The maximum unit separation and vertical lift (compressor above the evaporator) must be taking into account. Do not exceed allowable refrigerant line lengths.
Indoor unit
Unit must be installed in a location that does not obstruct the ow of air
and ensures clearances are maintained. (Fig. 1)
The site must support the weight of the unit.
The site must be easily accessible for cleaning or replacement of the air lter, maintenance and service.
The indoor unit should be mounted as high up on the wall toward the ceiling, leaving a minimum of 6” (150mm) of space between the ceiling
and the top of the indoor unit. (Fig. 1)
Due to the possibility of electronic interference with other devices, it is
recommended that there should be at least to 3 ft (1 meter) between the unit and other devices/appliances such as televisions or radios.
The unit should be installed away from possible exposure to re, smoke, of ammable gases and be protected from direct sunlight (sunlight can
interfere with the signal between the unit and the remote controller.
Outdoor unit
If installation location allows the unit to be exposed to strong winds (such as coastal applications), ensure that the unit has a wind barrier. This will
assist with preventing strong gusts of wind from entering the unit’s cabinet and interfering with the fan operation. (Fig. 3 and Fig. 4)

Avoid areas where water, snow, or ice may fall from the roof onto the unit.
In climates where snow is a consideration, locate the unit away from areas prone to drifting.
Ensure the location of the unit will not be subject to snow drifts, heavy accumulation of snow or leaves or other seasonal debris. If unavailable, provide an awning for the unit. (Fig. 5 and Fig. 6)
1. An awning can be built over the outdoor unit to prevent direct sunlight, rain exposure, or snowfall.
2. Ensure that the awning does not impede the unit’s required clearances or obstruct air ow.
3. The awning should be at least 2 ft. (0.6m) away from the top of the unit’s housing.
Ensure free ow of air into and out of the unit. All air inlet/outlets should be free of obstructions such as walls and shrubs. Minimum clearances should be maintained. (Fig. 2)
During heating and defrost modes (heat pump models only), the condensate should be properly drained away from the unit. Use the included drain joint and seal along with locally purchased hose to do so. (Fig. 8)
Do not locate two or more units in any way that will block discharge air from one unit to another. Be certain that hot air from one unit will not blow into a nearby unit to prevent recirculation or discharge air. (Fig. 7)
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.
Oil traps must be made in the refrigerant line set (every 10 ft.) when the outdoor unit is located above the indoor unit.
