Safety Cautions
1.2 Warnings and Cautions Regarding Safety of Users
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.
Do not mix air or gas other than the specified refrigerant (R-32 /
R-410A / R-22) in the refrigerant system.
If air enters the refrigerant 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 the
refrigerant, make sure that there is no leak.
If the leaking point cannot be located and the repair work must be
stopped, be sure to pump-down, and close the service valve, to prevent
refrigerant gas from leaking into the room. Refrigerant gas itself is
harmless, but it may generate toxic gases when it contacts flames, such
as those from fan type 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 or the installation
work is not conducted securely, the equipment may fall and cause injury.
