1. SAFETY CONSIDERATIONS

Read these “SAFETY CONSIDERATIONS for Installation” care-

fully before installing air conditioning equipment. After complet-

ing the installation, make sure that the unit operates properly

during the startup operation.

Instruct the customer on how to operate and maintain the unit.

Inform customers that they should store this Installation Manual

with the Operation Manual for future reference.

Always use a licensed installer or contractor to install this prod-

uct. Improper installation can result in water or refrigerant leak-

age, electrical shock, fire, or explosion.

Meanings of DANGER, WARNING, CAUTION, and NOTE

Symbols:

DANGER.................Indicates an imminently hazardous

situation which, if not avoided, will

result in death or serious injury.

WARNING ...............Indicates a potentially hazardous situ-

ation which, if not avoided, could result

in death or serious injury.

CAUTION ................Indicates a potentially hazardous situ-

ation which, if not avoided, may result

in minor or moderate injury.

It may also be used to alert against

unsafe practices.

NOTE ......................Indicates situations that may result in

equipment or property-damage acci-

dents only.

DANGER

• Refrigerant gas is heavier than air and replaces oxygen.

A massive leak can 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, gas pipes, telephone

wires, or lightning rods as incomplete grounding can

cause a severe shock hazard resulting in severe injury or

death. Additionally, grounding to gas pipes could cause

a gas leak and potential explosion causing severe injury

or death.

• If refrigerant gas leaks during installation, ventilate the

area immediately. Refrigerant gas may produce toxic gas

if it comes in contact with fire. Exposure to this gas

could cause severe injury or death.

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

frigerant gas does not leak throughout the system.

• Do not install unit in an area where flammable materials

are present due to risk of explosions that can cause se-

rious injury or death.

• Safely dispose all packing and transportation materials

in accordance with federal/state/local laws or ordi-

nances. Packing materials such as nails and other metal

or wood parts, including plastic packing materials used

for transportation may cause injuries or death by suffo-

cation.

WARNING

• Only qualified personnel must carry out the installation

work. Installation must be done in accordance with this

installation manual. Improper installation may result in

water leakage, electric shock, or fire.

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

to keep the refrigerant concentration from exceeding al-

lowable safety limits. Excessive refrigerant leaks, in the

event of an accident in a closed ambient space, can lead

to oxygen deficiency.

• Use only specified accessories and parts for installation

work. Failure to use specified parts may result in water

leakage, electric shocks, fire, or the unit falling.

• Install the air conditioner on a foundation strong enough

that it can withstand the weight of the unit. A foundation

of insufficient strength may result in the unit falling and

causing injuries.

• Take into account strong winds, typhoons, or earth-

quakes when installing. Improper installation may result

in the unit falling and causing accidents.

• Make sure that a separate power supply circuit is provid-

ed for this unit and that all electrical work is carried out

by qualified personnel according to local state, and na-

tional regulations. An insufficient power supply capacity

or improper electrical construction may lead to electric

shocks or fire.

• Make sure that all wiring is secured, that specified wires

are used, and that no external forces act on the terminal

connections or wires. Improper connections or installa-

tion may result in fire.

• When wiring, position the wires so that the electrical

components box lid can be securely fastened. Improper

positioning of the electrical components box lid may re-

sult in electric shocks, fire, or the terminals overheating.

• Before touching electrical parts, turn off the unit.

• Be sure to install a ground fault circuit interrupter if one

is not already available. This helps prevent electrical

shocks or fire.
