Power supply cord of parts of appliance for outdoor use shall be at least polychloroprene sheathed flexible cord (design H07RN-F) or cord
designation 245 IEC66 (1.5 mm
2
or more). (Shall be installed in accordance with national wiring regulations.)
PRECAUTIONS FOR SAFETY
CAUTION
•THIS AIR CONDITIONER USES THE NEW HFC REFRIGERANT (R410A), WHICH DOES NOT DESTROY THE 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 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 high-
pressure 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.
New refrigerant air conditioner installation
CAUTION
This appliance must be connected to the main power supply by means of a circuit breaker or a switch with a contact separation of at least 3 mm in
all poles. The installation fuse (25A) must be used for the power supply line of this air conditioner.
To disconnect the appliance from the main power supply
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 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.
WARNING
•Never modify this unit by removing any of the safety guards or bypassing 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.

noise and discharged air might disturb neighbors.
•To avoid personal injury, be careful when handling parts with sharp edges.
•Please read this installation manual carefully before installing the unit. It contains further important instructions for proper installation.

To prevent flicker impressions during the start of the compressor (technical process), following installation conditions does apply.
1.The power connection for the air conditioner has to be done at the main power distribution. This distribution has to be of an impedance.
Normally, the required impedance is reached at a 32A fusing point. Air conditioner fuse has to be 16A max.!
2.No other equipment should be connected to this power line.
3.For detailed installation acceptance, please contact your power supplier whether its restriction does apply for products like washing machines,
air conditioners or electric ovens.
4.For power details of the air conditioner, refer to the rating plate of the product.
