Warning 

Do not repair the electrical components with wet hands . Working on the equipment with wet hands can 
cause an electrical shock 

Do not clean the air conditioner by splashing water. Washing the unit with water can cause an electrical 
shock. 

Be  sure  to  provide  the  grounding  when  repairing  the  equipment  in  a  humid  or  wet  place,  to  avoid 
electrical 
shock. 

 

Be sure to turn off the power switch and unplug the power cable when cleaning the equipment. The 
internal fan rotates at a high speed, and cause injury. 

Do not tilt the unit when removing it. The water inside the unit can spill and wet the furniture and floor. 

Be  sure  to  check  that  the  refrigerating  cycle  section  has  cooled  down  sufficiently  before  conducting 
repair 
work. Working on the unit when the refrigerating cycle section is hot can cause burns. 

 

Use the welder in a well-ventilated place. Using the welder in an enclosed room can cause oxygen 
deficiency. 

 

1.2.2  Cautions Regarding Products after Repair 

         

Warning 

Be sure to use parts listed in the service parts list of the applicable model and appropriate tools to 
conduct repair work. Never attempt to modify the equipment. The use of inappropriate parts or tools can 
cause an electrical shock, excessive heat generation or fire.

 

 

When relocating the equipment, make sure that the new installation site has sufficient strength to 
withstand the weight of the equipment. 
If the installation site does not have sufficient strength and if the installation work is not conducted 
securely, the equipment can fall and cause injury.

 

 

Be sure to install the product correctly by using the provided standard installation frame. 
Incorrect use of the installation frame and improper installation can cause the equipment to fall, resulting 
in injury.

 

For 
integral 
units only

 

Be sure to install the product securely in the installation frame mounted on a window frame. 
If the unit is not securely mounted, it can fall and cause injury.

 

For 
integral
