1.2 Warnings and Cautions Regarding Safety of Users
Be sure to check that the refrigerating cycle section has cooled
down enough before conducting repair work.
Working on the unit when the refrigerating cycle section is hot may cause
burns.
Conduct welding work in a well-ventilated place.
Using the welder in an enclosed room may cause oxygen deficiency.
Caution
Warning
Do not store the equipment in a room with fire sources (e.g., naked
flames, gas appliances, electric heaters).
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 may cause an electrical shock,
excessive heat generation or fire.
If the power cable and lead wires are scratched or have deteriorated,
be sure to replace them.
Damaged cable and wires may cause an electrical shock, excessive heat
generation or fire.
Do not use a joined power cable or extension cable, or share the
same power outlet with other electrical appliances, since it may
cause an electrical shock, excessive heat generation or fire.
Be sure to use an exclusive power circuit for the equipment, and
follow the local technical standards related to the electrical
equipment, the internal wiring regulations, and the instruction
manual for installation when conducting electrical work.
Insufficient power circuit capacity and improper electrical work may cause
an electrical shock or fire.
Be sure to use the specified cable for wiring between the indoor and
outdoor units.
Make the connections securely and route the cable properly so that there
is no force pulling the cable at the connection terminals.
Improper connections may cause excessive heat generation or fire.
When wiring between the indoor and outdoor units, make sure that
the terminal cover does not lift off or dismount because of the cable.
If the cover is not mounted properly, the terminal connection section may
cause an electrical shock, excessive heat generation or fire.
Do not damage or modify the power cable.
Damaged or modified power cables may cause an electrical shock or fire.
Placing heavy items on the power cable, or heating or pulling the power
cable may damage it.
