DANGER
WARNING
CAUTION
It indicates that incorrect use of this unit can result in a high possibility of severe injury (*1) or death.
It indicates that incorrect use of this unit may cause severe injury or death.
It indicates that incorrect use of this unit may cause personal injury (*2), or property damage (*3).
*1 : A severe injury refers to blindness, injury, burns (hot or cold), electrical shock, bone fracture, or poisoning that leaves aftereffects and
requires hospitalization or extended out-patient treatment.

*3 : Property damage means greater damage which affects assets or resources.
For general public use
Power supply cord of parts of appliance for outdoor use shall be at least polychloroprene sheathed flexible cord (design H07RN-F) or cord designation
CAUTION New refrigerant air conditioner installation
THIS AIR CONDITIONER USES THE NEW HFC REFRIGERANT (R410A), WHICH DOES NOT DESTROY THE OZONE LAYER.
R410A refrigerant is apt to be affected by impurities such as water, oxidizing membranes, and oils because the pressure of R410A refrigerant is approx.
1.6 times of refrigerant R22. As well as the adoption of this new refrigerant, refrigerating machine oil has also been changed. Therefore, during installation
work, be sure that water, dust, former refrigerant, or refrigerating machine oil does not enter the refrigeration cycle of a new-refrigerant air conditioner.
To avoid mixing refrigerant and refrigerating machine oil, the sizes of charging port connecting sections on the main unit are different from those for the
conventional refrigerant, and different size tools are also required. For connecting pipes, use new and clean piping materials with high pressure withstand
capabilities, designed for R410A only, and ensure that water or dust does not enter. Moreover, do not use any existing piping as its pressure withstand
may be insufficient and may contain impurities.
60245 IEC66 (1.5 mm2 or more). (Shall be installed in accordance with national wiring regulations
DANGER
• FOR USE BY QUALIFIED PERSONS ONLY.
• MEANS FOR DISCONNECTION FROM THE SUPPLY HAVING A CONTACT SEPERATION OF AT LEAST 3 mm IN ALL POLES MUST BE
INCORPORATED IN THE FIXED WIRING.
• TURN OFF MAIN POWER SUPPLY BEFORE ATTEMPTING ANY ELECTRICAL WORK. MAKE SURE ALL POWER SWITCHES ARE OFF. FAILURE
TO DO SO MAY CAUSE ELECTRIC SHOCK.
• CONNECT THE CONNECTING CABLE CORRECTLY. IF THE CONNECTING CABLE IS CONNECTED WRONGLY, ELECTRIC PARTS MAY BE
DAMAGED.
• CHECK THE EARTH WIRE THAT IT IS NOT BROKEN OR DISCONNECTED BEFORE INSTALLATION.
• DO NOT INSTALL NEAR CONCENTRATIONS OF COMBUSTIBLE GAS OR GAS VAPORS. FAILURE TO FOLLOW THIS INSTRUCTION CAN
RESULT IN FIRE OR EXPLOSION.
• TO PREVENT OVERHEATING THE INDOOR UNIT AND CAUSING A FIRE HAZARD, PLACE THE UNIT WELL AWAY (MORE THAN 2 M) FROM
HEAT SOURCES SUCH AS RADIATORS, HEATERS, FURNACE, STOVES, ETC.
• WHEN MOVING THE AIR CONDITIONER FOR INSTALLING IT IN ANOTHER PLACE AGAIN, BE VERY CAREFUL NOT TO GET THE SPECIFIED
REFRIGERANT (R410A) WITH ANY OTHER GASEOUS BODY INTO THE REFRIGERATION CYCLE. IF AIR OR ANY OTHER GAS IS MIXED IN
THE REFRIGERANT, THE GAS PRESSURE IN THE REFRIGERATION CYCLE BECOMES ABNORMALLY HIGH AND IT RESULTINGLY CAUSES
BURST OF THE PIPE AND INJURIES ON PERSONS.
• IN THE EVENT THAT THE REFRIGERANT GAS LEAKS OUT OF THE PIPE DURING THE INSTALLATION WORK, IMMEDIATELY LET FRESH AIR
INTO THE ROOM. IF THE REFRIGERANT GAS IS HEATED BY FIRE OR SOMETHING ELSE, IT CAUSES GENERATION OF POISONOUS GAS.
• WHEN INSTALLING OR RE-INSTALLING THE AIR CONDITIONER, DO NOT INJECT AIR OR OTHER SUBSTANCES BESIDES THE DESIGNATED
REFRIGERANT “R410A” INTO THE REFRIGERATING CYCLE. IF AIR OR OTHER SUBSTANCES ARE MIXED, AN ABNORMAL PRESSURE CAN
OCCUR IN THE REFRIGERATING CYCLE, AND THIS CAN CAUSE AN INJURY DUE TO A PIPE RUPTURE.
1

WARNING
• Installation work must be requested from the supplying retail dealership or professional vendors. Self-installation may cause water leakage, electrical
shock, or fire as a result of improper installation.
• Specified tools and pipe parts for model R410A are required, and installation work must be done in accordance with the manual. HFC type refrigerant
R410A has 1.6 times more pressure than that of conventional refrigerant (R22). Use the specif ed pipe parts, and ensure correct installation, otherwise
damage and/or injury may be caused. At the same time, water leakage, electrical shock, and fire may occur.
• Be sure to install the unit in a place which can sufficiently bear its weight. If the load bearing of the unit is not enough, or installation of the unit is
improper, the unit may fall and result in injury.
• Electrical work must be performed by a qualified electrical engineer in accordance with the code governing such installation work, internal wiring
regulations, and the manual. A dedicated circuit and the rated voltage must be used. Insufficient power supply or improper installation may cause
electrical shock or fi re.
• Use a cabtyre cable to connect wires in the indoor/outdoor units. Midway connection, stranded wire, and single-wire connections are not allowed.
Improper connection or fixing may cause a fire.
• Wiring between the indoor unit and outdoor units must be well shaped so that the cover can be firmly placed. Improper cover installation may cause
increased heat, fi re, or electrical shock at the terminal area.
• Be sure to use only approved accessories or the specified parts. Failure to do so may cause the unit to fall, water leakage, fi re or electrical shock.
• After the installation work, ensure that there is no leakage of refrigerant gas. If the refrigerant gas leaks out of the pipe into the room and is heated by
fire or something else from a fan heater, stove or gas range, it causes generation of poisonous gas.
• Make sure the equipment is properly earthed. Do not connect the earth wire to a gas pipe, water pipe, lightning conductor, or telephone earth wire.
Improper earth work may be the cause of electrical shock.
• Do not install the unit where flammable gas may leak. If there is any gas leakage or accumulation around the unit, it can cause a fire.
• Do not select a location for installation where there may be excessive water or humidity, such as a bathroom. Deterioration of insulation may cause
electrical shock or fire.
• Installation work must be performed following the instructions in this installation manual. Improper installation may cause water leakage, electrical
shock or fire. Check the following items before operating the unit.
- Be sure that the pipe connection is well placed and there are no leaks.
- Check that the service valve is open. If the service valve is closed, it may cause overpressure and result in compressor damage. At the same time, if
there is a leak in the connection part, it may cause air suction and overpressure, resulting burst or injury.
• In pump down operations, ensure to perform the following procedures.
- Do not inject air into the refrigeration cycle.
- Be sure to close both service valves and stop the compressor before removing the refrigerant pipe. If removing the refrigerant pipe while the
compressor is operating with the service valves opened, it may cause to air absorbed and abnormal high pressure inside the refrigeration cycle and
resulting burst or injury.
• Do not modify the power cable, connect the cable midway, or use a multiple outlet extension cable. Doing so may cause contact failure, insulation
failure, or excess current, resulting in fire or electrical shock.
• Do not use any refrigerant different from the one specif ed for complement or replacement. Otherwise, abnormally high pressure may be generated in
the refrigeration cycle, which may result in a failure or explosion of the product or an injury to your body.
• Be sure to comply with local regulations/codes when running the wire from the outdoor unit to the indoor unit. (Size of wire and wiring method etc.)
• Places where iron or other metal dust is present. If iron or other metal dust adheres to or collects on the interior of the air conditioner, it may
spontaneously combust and start a fire.
• If you detect any damage, do not install the unit. Contact your supplying dealer immediately.
• Never modify this unit by removing any of the safety guards.
• Do not install in a place which cannot bear the weight of the unit. Personal injury and property damage can result if the unit falls.

surface, the indoor unit may unstably be set on the wall.
When bending the connecting pipe, make sure to use a spring bender so as
not to crush the pipe.
Bend the connecting pipe within a radius of 30 mm.

NOTE
If the pipe is bent incorrectly, the indoor unit may unstably be set on the wall.
After passing the connecting pipe through the pipe hole, connect the
connecting pipes to the auxiliary pipes and wrap the facing tape around
them.
CAUTION
Bind the auxiliary pipes (two) and connecting cable with facing tape
tightly. In case of leftward piping and rear-leftward piping, bind the
auxiliary pipes (two) only with facing tape.

Connecting cable
Carefully arrange pipes so that any pipe does not stick out of the rear
plate of the indoor unit.
Carefully connect the auxiliary pipes and connecting pipes to one
another and cut off the insulating tape wound on the connecting pipe
to avoid double-taping at the joint; moreover, seal the joint with the
vinyl tape, etc.
Since dewing results in a machine trouble, make sure to insulate both
connecting pipes. (Use polyethylene foam as insulating material.)
When bending a pipe, carefully do it, not to crush it.

CAUTION
Arrange the drain pipe for proper drainage from the unit.
Improper drainage can result in dew-dropping.
This air conditioner has the structure designed
to drain water collected from dew, which forms
on the back of the indoor unit, to the drain pan.
Therefore, do not store the power cord and other
parts at a height above the drain guide.
