●
Sharp bending of the pipe use the polyethylene rod, bend not crushed the pipe. Gas leakage from the
crushed part, stagnation, touching fi re, rarely cause ignition.
●
Please request your sales agent or qualifi ed technician to install your unit. Water leakage, short circuit
or fi re may occur if you do the installation work yourself.
●
Home Please observe the instructions stated in the installation manual during the process of installation. Improper
installation may cause water leakage, electric shock and fi re.
● Make sure that the units are mounted at locations which are able to provide full support to the weight
of the units. If not, the units may collapse and impose danger.
● Observe the rules and regulations of the electrical installation and the methods described in the installation
manual when dealing with the electrical work. Use cables which are offi cially approved in your country.
Be sure to use the specifi ed circuit. A short circuit and fi re may occur due to the use of low quality wire
or improper work.
● Be sure to use the specifi ed cables for connecting the indoor and outdoor units. Please ensure that

RAC-GJ12WHAA ● When installing or transferring an air conditioner to another location, make sure that air other than the
specifi ed refrigerant(R32) does not enter the refrigeration cycle. If other air should enter, the pressure
level of the refrigeration cycle may increase abnormally which could result in a rupture and injury.
EN INSTRUCTION MANUAL ● Be sure to ventilate fully if a refrigerant gas leak while at work. If the refrigerant gas comes into contact
with fi re, a poisonous gas may occur.
● After completion of installation work, check to make sure that there is no refrigeration gas leakage. If the
refrigerant gas leaks into the room, coming into contact with fi re in the fan-driven heater, space heater,

Installation of Drain Hose
● Do not guide the drain hose to places where corrosive gases (sulfur, ammonia, etc.) are generated,
such as septic tanks and sewer.
Corrosive gas may fl ow backward from the drain hose to the indoor unit, corrode the copper pipe, or
it may cause offensive odors in the room.
● Cut the drain hose at a position 3-15/16"(100mm) higher than the fl oor surface. It may cause water
leakage due to air lock or clogging of foreign matter.
!
CAUTION
OUTDOOR UNIT
WARNING
!
The outdoor unit must be mounted at a location which can support heavy weight. Otherwise,
noise and vibration will increase.
CAUTION
!
A circuit breaker or fuse must be installed. Without a circuit breaker or fuse the danger of electric shock exists.
The external switch shall be incorporated to completely disconnect from power supply. It should disconnect all
poles, and a contact separation of at least 4/32" (3mm) must be present.
Do not install the unit near a location where there is fl ammable gas. The outdoor unit may
catch fi re if fl ammable gas leaks around it.
Do not install the indoor unit in a machine shop, kitchen and laundry rooms when vapor
from oil or its mist fl ows to the indoor unit. The oil will deposit on the heat exchanger,
thereby reducing the indoor unit performance and may deform and in the worst case, break the plastic parts
of the indoor unit.
Please ensure smooth fl ow of water when installing the drain hose.
Piping shall be suitable supported with a maximum spacing of 3-9/32ft (1m) between the supports.
Selecting the installation location: Suitable location that will reduce the impact from rain and direct sun that
may affect the unit performance. Besides that, ventillation must be good and clear of obstruction.
The air blown out of the unit should not point directly to animals or plants.
The clearances of the unit from top, left, right and front are specifi ed in fi gure below. At least three of the
above sides must be open air.
Be sure that the hot air blown out of the unit and noise do not disturb the neighbourhood.
Do not install at a location where there is fl ammable gas, steam, oil and smoke.
The location must be convenient for water drainage.
Place the outdoor unit and its connection wire at least 3-9/32ft (1m) away from the antenna or signal line of
television, radio or telephone. This is to avoid noise interference.
Do not install outdoor unit facing strong wind direction. It may damage the fan motor.
Do not install the outdoor unit in a place where small animals may build their nests. If small animal goes
inside the unit and touches the electrical parts, failure of the unit, smoke or fi re may be caused. Request your
customer to keep the surrounding of the unit is clean.
Safely dispose all packing and transportation materials in accordance with federal/state/local laws orordinances.
Packing materials such as nails and other metal or wood parts, including plastic packing materials used for
transportation may cause injuries or death by suffocation.
The maximum number of pieces of equipment permitted to be stored together will be determined by local
regulations. Storage package protection should be constructed in such a way that mechanical damage to the
equipment inside the package will not cause a leak of the REFRIGERANT CHARGE.
