Safety Considerations
Refer also to the General Safety Considerations in the
separate booklet.
Read the precautions in this manual
carefully before operating the unit.
Read these Safety Considerations for Installation carefully
before installing an air conditioner or heat pump. After
completing the installation, make sure that the unit operates
properly during the startup operation.
Instruct the user on how to operate and maintain the unit.
Inform users that they should store this installation manual
with the operation manual for future reference.
Always use a licensed installer or contractor to install this product.
Improper installation can result in water or refrigerant leakage,
electric shock, re, 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 practices.
NOTE
................
Indicates situations that may result
in equipment or property damage
accidents 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 into contact with re. Exposure to this gas could
cause severe injury or death.
• After completing the installation work, check that the
refrigerant gas does not leak throughout the system.
•
Do not install unit in an area where ammable 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, including plastic packing materials used for
transportation may cause injuries or death by suffocation.
WARNING
• Only qualied personnel licensed or certied in their jurisdiction
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 re.
• 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 deciency.
• Use only specied accessories and parts for installation
work. Failure to use specied parts may result in water
leakage, electric shock, re, or the unit falling.
• Install the air conditioner or heat pump on a foundation
strong enough that it can withstand the weight of the unit.
A foundation of insuf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
falling 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 qualied personnel
licensed or certied in their jurisdiction according to local, state,
and national regulations. An insufcient power supply capacity or
improper electrical construction may lead to electric shock or re.
• Make sure that all wiring is secured, that specied wires are
used, and that no external forces act on the terminal connections
or wires. Improper connections or installation may result in re.
