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, 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 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 into contact with fire. 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 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, including 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,
electric 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, electric shock, fire, 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 insufficient 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.
