SAFETY CONSIDERATIONS

Read these 

SAFETY CONSIDERATIONS for Installation

 

carefully before installing air conditioning equipment. After com-
pleting the installation, make sure that the unit operates prop-
erly 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.

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 prac-
tices.

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 seri-
ous injury or death.

• Safely dispose of all packing and transportation materi-

als 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 control box 

cover can be securely fastened. Improper positioning of 
the control box cover may result in electric shocks, fire, 
or the terminals overheating.
