1. SAFETY PRECAUTIONS
For general public use
Power supply cord of outdoor unit shall be more than 1.5 mm ² (H07RN-F or 60245IEC66) polychloroprene
sheathed flexible cord.
• Read this “SAFETY PRECAUTIONS” carefully before servicing.
• The precautions described below include the important items regarding safety. Observe them without fail.
• After the servicing work, perform a trial operation to check for any problem.
• Turn off the main power supply switch (or breaker) before the unit maintenance.
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 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
into 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 used for the conventional refrigerant units.
Accordingly, special tools are required for the new refrigerant (R410A) units. 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
This appliance must be connected to the main power supply by a circuit breaker or a switch with a contact
separation of at least 3 mm.
DANGER
• ASK AN AUTHORIZED DEALER OR QUALIFIED INSTALLATION PROFESSIONAL TO INSTALL/
MAINTAIN THE AIR CONDITIONER.
INAPPROPRIATE SERVICING MAY RESULT IN WATER LEAKAGE, ELECTRIC SHOCK OR FIRE.
• 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.
DANGER: HIGH VOLTAGE
The high voltage circuit is incorporated.
Be careful to do the check service, as the electric shock may be caused in case of touching parts
on the P.C. board by hand.
• CORRECTLY CONNECT THE CONNECTING CABLE. IF THE CONNECTING CABLE IS INCOR-
RECTLY CONNECTED, ELECTRIC PARTS MAY BE DAMAGED.
• CHECK THAT THE EARTH WIRE IS NOT BROKEN OR DISCONNECTED BEFORE SERVICE AND
INSTALLATION. FAILURE TO DO SO MAY CAUSE ELECTRIC SHOCK.

• DO NOT INSTALL NEAR CONCENTRATIONS OF COMBUSTIBLE GAS OR GAS VAPORS. FAILURE
TO FOLLOW THIS INSTRUCTION CAN RESULT IN FIRE OR EXPLOSION.
• 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
REGISTERS, FURNACE, STOVES, ETC.
• WHEN MOVING THE AIR CONDITIONER FOR INSTALLATION IN ANOTHER PLACE, BE VERY CARE-
FUL 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 IS
MIXED IN THE REFRIGERANT, THE GAS PRESSURE IN THE REFRIGERATION CIRCUIT WILL
BECOME ABNORMALLY HIGH AND IT MAY RESULT IN THE PIPE BURSTING AND POSSIBLE
PERSONNEL INJURIES.
• IN THE EVENT THAT THE REFRIGERANT GAS LEAKS OUT OF THE PIPE DURING THE SERVICE
WORK AND THE INSTALLATION WORK, IMMEDIATELY LET FRESH AIR INTO THE ROOM.
IF THE REFRIGERANT GAS IS HEATED, SUCH AS BY FIRE, GENERATION OF POISONOUS GAS
MAY RESULT.
WARNING
• Never modify this unit by removing any of the safety guards or bypass any of the safety interlock
switches.
• 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.
• After the installation work, confirm that refrigerant gas does not leak.
If refrigerant gas leaks into the room and flows near a fire source, such as a cooking range, noxious gas
may generate.
• The electrical work must be performed by a qualified electrician in accordance with the Installa-
tion Manual. Make sure the air conditioner uses an exclusive circuit.
An insufficient circuit capacity or inappropriate installation may cause fire.
• When wiring, use the specified cables and connect the terminals securely to prevent external
forces applied to the cable from affecting the terminals.
• Be sure to provide grounding.
Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone cables.
• Conform to the regulations of the local electric company when wiring the power supply.
Inappropriate grounding may cause electric shock.
CAUTION
• Exposure of unit to water or other moisture before installation may result in an electrical short.
Do not store in a wet basement or expose to rain or water.
• Do not install in a place that can increase the vibration of the unit. Do not install in a place that can
amplify the noise level of the unit or where noise or discharged air might disturb neighbors.
• To avoid personal injury, be careful when handling parts with sharp edges.
• Perform the specified installation work to guard against an earthquake.
If the air conditioner is not installed appropriately, accidents may occur due to the falling unit.
For Reference:
If a heating operation would be continuously performed for a long time under the condition that the outdoor
temperature is 0°C or lower, drainage of defrosted water may be difficult due to freezing of the bottom
plate, resulting in a trouble of the cabinet or fan.
It is recommended to procure an antifreeze heater locally for a safe installation of the air conditioner.
For details, contact the dealer.
