8. INSTALLATION PROCEDURE

8-1. Safety Cautions

For general public use

Power supply cord of parts of appliance for Outdoor use shall be more than polychloroprene sheathed flexible

cord (design H05 RN-F), or cord designation 245 IEC 57.

CAUTION

TO DISCONNECT THE APPLIANCE FROM THE MAINS SUPPLY.

This appliance must be connected to the mains by means of a circuit breaker or a switch with a contact

separation of at least 3 mm.

If this is not possible, a power supply plug with earth must be used. This plug must be easily accessible after

installation. The plug must be disconnected from the power supply socket in order to disconnect the appliance

completely from the mains.

DANGER

` FOR USE BY QUALIFIED PERSONS ONLY.

` TURN OFF MAIN POWER SUPPLY AND BREAKER BEFORE ATTEMPTING ANY ELECTRICAL WORK.

MAKE SURE ALL POWER SWITCHES AND BREAKER TURN OFF. FAILURE TO DO SO MAY CAUSE

ELECTRICAL SHOCK.

` CONNECT THE CONNECTING CABLE CORRECTLY. IF THE CONNECTING CABLE IS CONNECTED BY

WRONG WAY, ELECTRIC PARTS MAY BE DAMAGED.

` CHECK THE EARTH WIRE IS NOT BROKEN OR DISCONNECTED BEFORE INSTALLATION.

` DO NOT INSTALL NEAR CONCENTRATIONS OF COMBUSTIBLE GAS OF 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 2M.) FROM HEAT SOURCES SUCH AS RADIATORS, HEAT RESISTORS,

FURNACE, STOVES, ETC..

` WHEN MOVING THE AIR-CONDITIONER FOR INSTALLING IT IN ANOTHER PLACE AGAIN, BE VERY

CAREFUL NOT TO GET THE SPECIFIED REFRIGERANT (R-22) 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.
