WARNING
!
Wiring connections must be secured tightly and the cable should be
routed properly so that there is no force pulling the cable from the
connection terminals. Improper or loose connections can cause heat
generation or fire.
Do not touch, operate, or repair the product with wet hands. Otherwise
there is risk of electric shock or fire.
CAUTION
!
Do not turn on the breaker when the front panel and cabinet are removed.
Be sure to ground the water heater with an earthing conductor connected
to the earthing terminal.
Conduct repair works after checking that the refrigerating cycle section
has cooled down sufficiently. Otherwise, working on the unit, the hot
refrigerating cycle section can cause burns.
Do not tilt the unit while removing panels. Otherwise, the water inside the
unit can spill and wet floor.
Do not use the welder in a well-ventilated place. Using the welder in an
enclosed room can cause oxygen deficiency.
Be sure to turn off power switch before connecting or disconnecting
connector, or parts damage may be occur.
Inspections after Repair
Check to see if the power cable is not dirty or loose. If the cable 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 product 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.
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
installation 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.
