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 60245 IEC66 (1.5 mm2 or more). (Shall be installed in accordance with national
wiring regulations.)
CAUTION
New Refrigerant Air Conditioner Installation
•
THIS AIR CONDITIONER ADOPTS THE NEW HFC REFRIGERANT (R410A) WHICH DOES NOT DESTROY
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 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 highpressure 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.
CAUTION
To disconnect the appliance from the main power supply
This appliance must be connected to the main power supply be means of a circuit breaker or a switch with a contact
separation of at least 3 mm in all poles.
The installation circuit breaker must be used specified for the power supply line of this air conditioner.
DANGER
•
FOR USE BY QUALIFIED PERSONS ONLY.
•
TURN OFF MAIN POWER SUPPLY BEFORE ATTEMPTING ANY ELECTRICAL WORK. MAKE SORE 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.
