1.1.2 Cautions Regarding Safety of Users
Warning
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 have scratches or 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 cable may cause an electrical shock or fire.
Placing heavy items on the power cable, and heating or pulling the power cable
may damage the cable.
Do not mix air or gas other than the specified refrigerant (R-410A / R-22) in the
refrigerant system.
If air enters the refrigerating system, an excessively high pressure results,
causing equipment damage and injury.
If the refrigerant gas leaks, be sure to locate the leaking point and repair it
before charging the refrigerant. After charging refrigerant, make sure that there
is no refrigerant leak.
If the leaking point cannot be located and the repair work must be stopped, be
sure to perform pump-down and close the service valve, to prevent the
refrigerant gas from leaking into the room. The refrigerant gas itself is
harmless, but it may generate toxic gases when it contacts flames, such as fan
and other heaters, stoves and ranges.
When relocating the equipment, make sure that the new installation site has
sufficient strength to withstand the weight of the equipment.
If the installation site does not have sufficient strength and if the installation
work is not conducted securely, the equipment may fall and cause injury.
