DANGER
• FOR USE BY QUALIFIED PERSONS ONLY.
• 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 OVERHEATION 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 LEAK, DURING INSTALLATION WORK, IMMEDIATELY ALLOW FRESH AIR
INTO THE ROOM. IF THE REFRIGERANT GAS IS HEATED BY FIRE OR SOMETHING ELSE, IT CAUSE GENERATION
OF POISONOUS GAS.
WARNING
• ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury or death.
Before installing, modifying, or servicing system, main electrical disconnect switch must be in the OFF position. There may
be more than 1 disconnect switch. Lock out and tag switch with a suitable warning label.
• Never modify this unit by removing any of the safety guards or bypassing any of the safety interlock switches.
• Installation work must be purformed by qualified personnel only.
• 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
specified 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 trained, qualified installers and service mechanics 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 fire.
• Use a cabtyre cable to connect wires in the indoor/outdoor units. Midway connection is 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, fire, 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,
fire 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 fanheater, stove or gas range, it causes generation of poisonous gas.
• Make sure the equipment is properly grounded. Do not connect the ground 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 nay 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
in damage to the unit or injury.
• In a pump-down operation, be sure to stop the compressor unit before removing the refrigerant pipe. If removing the
refrigerant pipe while the compressor is operating with the service valve opened, it may cause air suction and overpressure,
resulting in damage to the unit or injury.
• Do not modity 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.
• If you detect any damage, do not install the unit. Contact your dealer immediately.
