IMPORTANT NOTICE

• For details on how to install the indoor units, refer to the installation manual accompanying the indoor units.

1 SAFETY PRECAUTIONS

For general public use
• RAS-4M23SAV-E, RAS-4M23SACV-E
Power supply cord of outdoor unit shall be 1.5 mm
• RAS-3M26GAV-E, RAS-4M27GAV-E, RAS-4M27GACV-E
Power supply cord of outdoor unit shall be 2.5 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 4. 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
Disconnection from the supply mains:
The means for disconnection must be incorporated in the fixed wiring in accordance with the wiring rules.
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.
• CHECK THE FOLLOWING POINTS BEFORE STARTING OPERATION IN THE INSTALLATION WORK.
- THE PIPES ARE SECURELY CONNECTED AND DO NOT LEAK.
- THE SERVICE VALVE IS OPENED.
OPERATING THE COMPRESSOR WHILE THE SERVICE VALVE IS CLOSED WILL RESULT IN AN ABNORMALLY HIGH
PRESSURE, AND CAN POSSIBLY DAMAGE THE COMPRESSOR AND OTHER PARTS. ALSO, ANY LEAKS IN THE
CONNECTIONS CAN CAUSE AIR TO BE SUCKED IN, RESULTING IN AN EVEN HIGHER ABNORMALLY PRESSURE,
AND CAN CAUSE A PIPE RUPTURE OR INJURY.
• 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.
