• Consult the shop where you purchased the air conditioner if air 
conditioning (cooling and heating) is not performed properly as a 
refrigerant leakage may be the cause. Confirm the repair details 
with a qualified service person (*1) when the repair includes 
additional charging of the refrigerant.
• Stop running the air conditioner and turn off the breaker before 
cleaning.
Otherwise, injury may result as the fan is rotating at high speed 
inside the unit.
Repairs
• If there is any kind of trouble (such as when an error display has 
appeared, there is a smell of burning, abnormal sounds are heard, 
the air conditioner fails to cool or heat or water is leaking) has 
occurred in the air conditioner, do not touch the air conditioner 
yourself but set the circuit breaker to the OFF position, and 
contact a qualified service person (*1). Take steps to ensure that 
the power will not be turned on (by marking “out of service” near 
the circuit breaker, for instance) until qualified service person (*1) 
arrives. Continuing to use the air conditioner in the trouble status 
may cause mechanical problems to escalate or result in electric 
shocks or other trouble.
• If the fan grille is damaged, do not approach the outdoor unit but 
set the circuit breaker to the OFF position, and contact a qualified 
service person to have the repairs done. Do not set the circuit 
breaker to the ON position until the repairs are completed.
• If there is a danger of the indoor unit’s falling, do not approach 
the indoor unit but set the circuit breaker to the OFF position, and 
contact a qualified installer (*1) or a qualified service person (*1) 
to refit the unit. Do not set the circuit breaker to the ON position 
until the unit has been refitted.
• If there is a danger of the outdoor unit’s toppling over, do not 
approach the outdoor unit but set the circuit breaker to the OFF 
position, and contact a qualified installer (*1) or a qualified service 
person (*1) to have the improvements or refitting done. Do not set 
the circuit breaker to the ON position until the improvements or 
refitting is completed.
• Do not customize the unit. Doing so may result in fire, electric 
shock or other trouble.
Relocation
• When the air conditioner is to be relocated, do not relocate it 
yourself but contact a qualified installer (*1) or a qualified service 
person (*1). Failure to relocate the air conditioner properly may 
result in electric shocks and/or a fire.
 CAUTION
Installation
• Certainly lay the drain hose for perfect draining. Improper 
drainage may cause flooding in the house and getting furniture 
wet.
• Connect the air conditioner to an exclusive power supply of the 
rated voltage, otherwise the unit may break down or cause a fire.
• Confirm that the outdoor unit are fixed on the base. Otherwise, 
falling down of the units or other accidents may occur.
Operation
• Do not use this air conditioner for special purpose such as 
preserving food, precision instruments, art objects, breeding 
animals, car, vessel.
• Do not touch any switches with wet finger, otherwise you may get 
an electric shock.
• If the air conditioner will not be used for a considerably long time, 
turn off the main switch or the circuit breaker, for safety.
• To make the air conditioner operate in its original performance, 
operate it within the range of the operating temperature specified 
in the instructions. Otherwise it may cause a malfunction, or water 
leak from the unit.
