Caution 
Check to see if the parts and wires are mounted and connected properly, and if the connections at the 
soldered or crimped terminals are secure. Improper installation and connections can cause excessive 
heat generation, fire or an electrical shock.
 
 
If the installation platform or frame has corroded, replace it. Corroded installation platform or frame can 
cause the unit to fall, resulting in injury.
 
 
Check the grounding, and repair it if the equipment is not properly grounded. Improper grounding can 
cause an electrical shock.
 
Be sure to measure the insulation resistance after the repair, and make sure that the resistance is 1 M 
ohm or higher. 
Faulty insulation can cause an electrical shock.
 
 
Be sure to check the drainage of the indoor unit after the repair. 
Faulty drainage can cause the water to enter the room and wet the furniture and floor.
