¡ Make sure there is no dust or clogging on both the plug and the socket nor loose connection of the socket
before plugging, and plug in securely to the end of the blade.
Accumulation of dust, clogging on the socket or plug, or loose installation of the socket could cause electric shock
and fire. Replace the socket if it is loose.
¡ Connect the pipes for refrigeration circuit securely in installation work before compressor is operated.
If the compressor is operated when the service valve is open without connecting the pipe, it could cause explosion
and injuries due to abnormal high pressure in the system.
¡ Stop the compressor before removing the pipe on pump down work.
If the pipe is removed when the compressor is in operation with the service valve open, air would be mixed in the
refrigeration circuit and it could cause explosion and injuries due to abnormal high pressure in the cooling cycle.
¡ Use the genuine optional parts. And installation should be performed by a specialist.
If you install the unit by yourself, it could cause water leakage, electric shock and fire.
¡ Do not repair by yourself. And consult with the dealer about repair.
Improper repair may cause water leakage, electric shock or fire.
¡ Consult the dealer or a specialist about removal of the air conditioner.
Improper installation may cause water leakage, electric shock or fire.
¡ Turn off the power source during servicing or inspection work.
If the power is supplied during servicing or inspection work, it could cause electric shock and injury by the operating
fan.
¡ Do not run the unit when the panel or protection guard are taken off.
Touching the rotating equipment, hot surface, or high voltage section could cause an injury to be caught in the
machine, to get burned, or electric shock.
¡ Shut off the power before electrical wiring work.
It could cause electric shock, unit failure and improper running.
¡ Perform earth wiring surely.
Do not connect the earth wiring to the gas pipe, water pipe, lightning rod and telephone earth wiring. Improper earth
could cause unit failure and electric shock due to a short circuit.
¡ Use the circuit breaker of correct capacity.
Using the incorrect capacity one could cause the system failure and fire.
¡ Do not use any materials other than a fuse of correct capacity where a fuse should be used.
Connecting the circuit by wire or copper wire could cause unit failure and fire.
¡ Do not install the indoor unit near the location where there is possibility of flammable gas leakages.
If the gas leaks and gathers around the unit, it could cause fire.
¡ Do not install and use the unit where corrosive gas (such as sulfurous acid gas etc.) or flammable gas (such
as thinner, petroleum etc.) may be generated or accumulated, or volatile flammable substances are handled.
It could cause the corrosion of heat exchanger, breakage of plastic parts etc. And inflammable gas could cause fire.
¡ Do not use the indoor unit at the place where water splashes such as laundry.
Indoor unit is not waterproof. It could cause electric shock and fire.
¡ Do not use the indoor unit for a special purpose such as food storage, cooling for precision instrument,
preservation of animals, plants, and a work of art.
It could cause the damage of the items.
¡ Do not install nor use the system near equipments which generate electromagnetic wave or high harmon-
ics.
Equipments like inverter equipment, private power generator, high-frequency medical equipment, or telecommuni-
cation equipment might influence the air conditioner and cause a malfunction and breakdown. Or the air conditioner
might influence medical equipments or telecommunication equipments, and obstruct their medical activity or cause
jamming.
¡ Do not install the remote controller at the direct sunlight.
It could cause breakdown or deformation of the remote controller.
