1 SAFETY PRECAUTIONS

For general public use
Power supply cord of outdoor unit shall be 1.5 mm
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 membrane, and oils because the working pressure of
R410A refrigerant is approx. 1.6 times as that of refrigerant R22. Accompanied with the adoption of the new refrigerant, the
refrigeration machine oil has also been changed. Therefore, during installation work, be sure that water, dust, former refrigerant,
or refrigeration machine oil does not enter the new type refrigerant R410A air conditioner circuit.
To prevent mixing of refrigerant or refrigerating machine oil, the sizes of connecting sections of charging port on main unit and
installation tools are different from those of the conventional refrigerant units. Accordingly, special tools are required for the new
refrigerant (R410A) units as shown on page 5. For connecting pipes, use new and clean piping materials with high pressure
fittings made for R410A only, so that water and/or dust does not enter. Moreover, do not use the existing piping because there are
some problems with pressure fittings and possible impurities in existing piping.
CAUTION
TO DISCONNECT THE APPLIANCE FROM THE MAIN POWER SUPPLY
A switch or circuit breaker that can disconnect all poles must be included in the fixed wiring. Be sure to use an approved circuit
breaker or switch.
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.
• CORRECTLY CONNECT THE CONNECTING CABLE. IF THE CONNECTING CABLE IS INCORRECTLY CONNECTED,
ELECTRIC PARTS MAY BE DAMAGED.
• CHECK THAT THE EARTH WIRE IS NOT BROKEN OR DISCONNECTED BEFORE INSTALLATION. FAILURE TO DO SO
MAY CAUSE ELECTRIC SHOCK.
• DO NOT INSTALL THE UNIT IN A PLACE WHERE INFLAMMABLE GAS CAN LEAK. A FIRE CAN RESULT IF
INFLAMMABLE GAS ACCUMULATES AROUND THE UNIT.
• TO PREVENT THE INDOOR UNIT FROM OVERHEATING AND CAUSING A FIRE HAZARD, PLACE THE UNIT WELL
AWAY (MORE THAN 2 M) FROM HEAT SOURCES SUCH AS RADIATORS, HEAT REGISTORS, FURNACE, STOVES,
ETC.
• WHEN MOVING THE AIR-CONDITIONER FOR INSTALLATION TO ANOTHER PLACE, BE VERY CAREFUL NOT TO
ALLOW THE SPECIFIED REFRIGERANT (R410A) TO BECOME MIXED WITH ANY OTHER GASEOUS BODY INTO THE
REFRIGERATION CIRCUIT. IF AIR OR ANY OTHER GAS MIXES WITH THE REFRIGERANT, THE GAS PRESSURE IN
THE REFRIGERATION CIRCUIT WILL BECOME ABNORMALLY HIGH AND IT MAY RESULT IN THE PIPE BURSTING OR
PERSONNEL INJURIES.
• 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, POISONOUS GAS MAY
RESULT.
• WHEN INSTALLING THE AIR CONDITIONER UNIT, MAKE SURE THAT THE REFRIGERANT PIPE IS CONNECTED
SECURELY BEFORE THE COMPRESSOR IS OPERATED. IF THE COMPRESSOR IS OPERATED WITH THE
REFRIGERANT PIPE UNCONNECTED, WHICH MEANS THAT THE SERVICE VALVE WILL BE LEFT OPEN, AIR, ETC.
WILL BE SUCKED IN, CAUSING THE PRESSURE INSIDE THE REFRIGERATION CYCLE TO RISE TO AN
ABNORMALLY HIGH LEVEL, AND POSSIBLY RESULTING IN RUPTURE, INJURY, ETC.
• WHEN CARRYING OUT THE PUMP-DOWN WORK, SHUT DOWN THE COMPRESSOR BEFORE DISCONNECTING
THE REFRIGERANT PIPE. DISCONNECTING THE REFRIGERANT PIPE WITH THE SERVICE VALVE LEFT OPEN AND
WITH THE COMPRESSOR STILL OPERATING WILL CAUSE AIR, ETC. TO BE SUCKED IN, RAISING THE PRESSURE
INSIDE THE REFRIGERATION CYCLE TO AN ABNORMALLY HIGH LEVEL, AND POSSIBLY RESULTING IN
RUPTURING, INJURY, ETC.
