Safety Precautions

WARNING

Have the unit professionally installed.
Improper installation by an unqualified person may result
in water leak, electric shock, or fire.

Place the unit on a stable, level surface that withstands the
weight of the unit to prevent the unit from tipping over or
falling causing injury as a result.

Only use specified cables for wiring. Securely connect each
cable, and make sure that the cables are not straining the
terminals.
Cables not connected securely and properly may generate
heat and cause fire.

Take necessary safety measures against typhoons and
earthquakes to prevent the unit from falling over.

Do not make any changes or modifications to the unit. In
case of problems, consult the dealer.
If repairs are not made properly, the unit may leak water
and present a risk of electric shock, or it may produce smoke
or cause fire.

WARNING

and abnormal cycle and cause the unit to burst.

Do not touch the fins on the heat exchanger with bare hands,
for they are sharp and dangerous.

In the event of a refrigerant gas leak, provide adequate
ventilation to the room.
If leaked refrigerant gas is exposed to a heat source, noxious
gases may form.

With All-Fresh type air conditioners, outdoor air may be
directly blown into the room upon thermo off. Take this into
consideration when installing the unit.
Direct exposure to outdoor air may present a health hazard,
and it may also cause food items to deteriorate.

do not change the settings.
Defeating the safety features on the unit such as the pressure
switch and temperature switch or using parts other than the
dealer or specialist may result in fire or explosion.

When installing the unit in a small room, safeguard against
hypoxia that results from leaked refrigerant reaching the
threshold level.
Consult the dealer for necessary measures to take.

When relocating the air conditioner, consult the dealer or
a specialist.
Improper installation may result in water leak, electric shock,
or fire.

After completing the service work, check for a refrigerant
gas leak.
If leaked gas refrigerant is exposed to a heat source such
as fan heater,stove,and electric grill, noxious gases may
form.

Only use specified parts.
Have the unit professionally installed. Improper installation
may cause water leak, electric shock,smoke, or fire.
