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 a 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.
