1. SAFETY CONSIDERATIONS
Read these “SAFETY CONSIDERATIONS for Installation” carefully
before installing air conditioning equipment. After completing the instal-
lation, make sure that the unit operates properly during the startup oper-
ation.
Instruct the customer on how to operate and maintain the unit. Inform
customers that they should store this Installation Manual with the Oper-
ation Manual for future reference.
Always use a licensed installer or contractor to install this product.
Improper installation can result in water or refrigerant leakage, 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 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 used to alert against unsafe prac-
tices.
NOTE
.............Indicates situations that may result in equipment or
property-damage accidents only.
DANGER
• Refrigerant gas is heavier than air and replaces oxygen. A mas-
sive leak can lead to oxygen depletion, especially in base-
ments, 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 refriger-
ant 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 serious injury
or death.
• Safely dispose all packing and transportation materials in
accordance with federal/state/local laws or ordinances. Packing
materials such as nails and other metal or wood parts, includ-
ing plastic packing materials used for transportation may cause
injuries or death by suffocation.
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, elec-
tric shock, or fire.
• When installing the unit in a small room, take measures to keep
the refrigerant concentration from exceeding allowable 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, elec-
tric 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 insuffi-
cient strength may result in the unit falling and causing injuries.
• Take into account strong winds, typhoons, or earthquakes
when installing. Improper installation may result in the unit fall-
ing and causing accidents.
• Make sure that a separate power supply circuit is provided for
this unit and that all electrical work is carried out by qualified
personnel according to local state, and national regulations. An
insufficient power supply capacity or improper electrical con-
struction 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 connec-
tions or wires. Improper connections or installation may result
in fire.
• When wiring, position the wires so that the terminal box lid can
be securely fastened. Improper positioning of the terminal box
lid may result in electric shocks, fire, or the terminals overheat-
ing.
• 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.
