Safety Considerations
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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.
