1.1.3 Inspection after Repair
Warning
Check to make sure that the power cable plug is not dirty or loose, then insert the plug into a power outlet
all the way.
If the plug has dust or loose connection, it can cause an electrical shock or fire.
If the power cable and lead wires have scratches or deteriorated, be sure to replace them.
Damaged cable and wires can cause an electrical shock, excessive heat generation or fire.
Warning
Do not use a joined power cable or extension cable, or share the same power outlet with other electrical
appliances, since it can cause an electrical shock, excessive heat generation or fire.
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.
