Safety Precaution

〉

VRV System is a class A product. In a domestic environment this prod-
uct may cause radio interference in which case the user may be
required to take adequate measures.

Meaning of danger, warning, caution and note symbols.

DANGER

.................... Indicates an imminently hazardous situa-

tion which,if not avoided, will result in death
or serious injury.

WARNING

.................. Indicates a potentially hazardous situation

which, if not avoided, could result in death
or serious injury.

CAUTION

.................... Indicates a potentially hazardous situation

which, if not avoided, may result in minor or
moderate injury. It may also be sued to
alert against unsafe practices.

NOTE

.......................... Indicates a situation that may result in the

unit or property-damage-only accidents.

DANGER

• Refrigerant gas is heavier air and replaces oxygen. A massive

leak could lead to oxygen depletion, especially in basements,
and an asphyxiation hazard could occur leading to serious
injury or death.

• Do not ground units to water pipes, telephone wires or light-

ning rods because incomplete grounding could cause a se-
vere shock hazard resulting in severe injury or death, and to
gas pipes because a gas leak could result in an explosion
which could lead to severe injury or death.

• If the refrigerant gas leaks during installation, ventilate the

area immediately.

Refrigerant gas may produce toxic gas if it comes in contact with fire
such as from a fan, heater, stove or cooking device. Exposure to this
gas could cause severe injury or death.

• After completing the installation work, check that the refriger-

ant gas does not leak.

Refrigerant gas may produce toxic gas if it comes in contact with fire
such as from a fan, heater, stove or cooking device. Exposure to this
gas could cause severe injury or death.

• Do not install unit in an area where flammable materials are

present due to risk of explosion resulting in serious injury or
death.

• Safely dispose of the packing materials.

Packing materials, such as nails and other metal or wooden parts,
may cause stabs or other injuries.
Tear apart and throw away plastic packaging bags so that children will
not play with them. Children playing with plastic bags face the danger
of death by suffocation.

WARNING

• Ask your dealer or qualified personnel to carry out installation

work. Do not try to install the unit by yourself.

Improper installation may result in water leakage, electric shocks or fire.

• Perform installation work in accordance with this installation

manual.

Improper installation may result in water leakage, electric shocks or fire.

• When installing the unit in a small room, take measures

against to keep refrigerant concentration from exceeding al-
lowable safety limits in the event of refrigerant leakage.

Contact the place of purchase for more information. Excessive refrig-
erant in a closed ambient can lead to oxygen deficiency.

• Be sure to use only the specified accessories and parts for in-

stallation work.
