 WARNING

Do not connect the power cord to an intermediate point, 
use an extension cord, or connect multiple devices to a 
single AC outlet.

•  This may cause overheating, fi re, or electric shock.

Make sure the power plug is free of dirt and insert it se-
curely into the outlet.

•  A dirty plug may cause fi re or electric shock.

Do not bundle, pull, or modify the power cord, and do not 
apply heat or place heavy objects on it.

•  This may cause fi re or electric shock.

Do not turn the breaker OFF/ON or disconnect/connect the 
power plug during operation.

•  This may create sparks, which can cause fi re.

•  After the indoor unit is switched OFF with the remote con-

troller, make sure to turn the breaker OFF or disconnect the 

power plug. 

Do not expose your body directly to cool air for a prolonged 
length of time.

•  This could be detrimental to your health.

The  unit  should  not  be  installed,  relocated,  or  repaired 
by the user.

•  An  improperly  handled  air  conditioner  may  cause  fi re  or 

electric shock.

This appliance is not intended for use by persons (includ-
ing  children)  with  reduced  physical,  sensory  or  mental 
capabilities, or lack of experience and knowledge, unless 
they have been given supervision or instruction concern-
ing use of the appliance by a person responsible for their 
safety.

Children should be supervised to ensure that they do not 
play with the appliance.

•  Since rotating parts and parts which could cause an electric shock are used 

in this product, be sure to read these “Safety Precautions” before use.

•  Since the cautionary items shown here are important for safety, be sure to 

observe them.

•  After reading this manual, keep it together with the installation manual in a 

handy place for easy reference.

•  Be  sure  to  receive  a  guarantee  card  from  your  dealer  and  check  that  the 

purchased date and shop name, etc. are entered correctly.

Marks and their meanings

 WARNING :

Incorrect  handling  could  cause  serious  hazard,  such  as 

death, serious injury, etc. with a high probability.

 CAUTION :

Incorrect handling could cause serious hazard depending 
on the conditions.

  

Do not insert your fi nger, a stick, or other objects into the 

air inlet or outlet.

•  This may cause injury, since the fan inside rotates at high 

speeds during operation.

  

In case of an abnormal condition (such as a burning smell), 
stop the air conditioner and disconnect the power plug or 
turn the breaker OFF.

•  A continued operation in the abnormal state may cause a 

malfunction, fi re, or electric shock. In this case, consult your 

dealer.

When the air conditioner does not cool or heat, there is 
a  possibility  of  refrigerant  leakage.  In  this  case,  consult 
your dealer. If a repair involves recharging the unit with 
refrigerant, ask the service technician for details.

•  The refrigerant used in the air conditioner is safe. Normally, 

it does not leak. However, if refrigerant leaks and comes in 

contact with a heat source such as a fan heater, kerosene 

heater, or cooking stove, it will create a harmful gas.

 CAUTION

Do  not  touch  the  air  inlet  or  the  aluminum  fi ns  of  the 

indoor/outdoor unit.

•  This may cause injury.

Do not use insecticides or fl ammable sprays on the unit.

•  This may cause a fi re or deformation of the unit.

Do not expose pets or houseplants to direct airfl ow.

•  This may cause injury to the pets or plants.

Do not place other electric appliances or furniture under 
the indoor/outdoor unit.

•  Water may drip down from the unit, which may cause damage 

or malfunction.

Do not leave the unit on a damaged installation stand.

•  The unit may fall and cause injury.
