Part 1 General Information
Check to see if the parts are mounted correctly and wires are connected.
Improper installation and connections can cause an electric shock or an injury.
Check whether the installation platform or frame has corroded. Corroded installa-
tion platform or frame can cause the unit to fall, resulting in injury.
Be sure to check whether the earth wire is correctly connected.
After the work has finished, be sure to do an insulation test to check whether the
resistance is 2[Mohm] or more between the charge section and the non-charge
metal section (Earth position). If the resistance value is low, a disaster such as a
leak or electric shock is caused at user’s side.
Check the drainage of the indoor unit after the repair. If drainage is faulty the
water may enter the room and wet floor.
1.2 Inspections after Repair
Check to see if the power cable plug is not dirty or loose. If the plug is dusty or
loose it can cause an electrical shock or fire.
Do not use a joined power cable or extension cable, or share the same power
outlet with other electrical appliances. otherwise, it can cause an electrical shock,
excessive heat generation or fire.
Do not insert hands or other objects through the air inlet or outlet while the prod-
uct is operating. There are sharp and moving parts that could cause personal
injury.
Do not block the inlet or outlet of air flow. It may cause product failure
