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.
• Before doing the electrical work, attach an approved plug to the power supply 

cord.

  Also, make sure the equipment is properly earthed.

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 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.
