To disconnect the appliance from the main power supply

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. 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 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  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 (R) 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.
