Safety Considerations
Read these Safety Considerations for Operations carefully
before operating an air conditioner or heat pump.
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 operation manual
with the installation manual for future reference.
Meanings of DANGER, WARNING, CAUTION, and NOTE
Symbols:
DANGER
WARNING
CAUTION
NOTE
• Do not install the unit in an area where ammable
materials are present due to risk of explosion resulting in
serious injury or death.
• Any abnormalities in the operation of the air conditioner
or heat pump, such as smoke or re, could result in
severe injury or death. Turn off the power and contact
your dealer immediately.
• Refrigerant gas may produce toxic gas if it comes into
contact with re, such as from a fan heater, stove, or
cooking device. Exposure to this gas could cause severe
injury or death.
• For refrigerant leakage, consult your dealer.
Refrigerant gas is heavier than air and replaces oxygen.
A massive leak could lead to oxygen depletion, especially
in basements, and an asphyxiation hazard could occur
leading to serious injury or death.
• If equipment utilizing a burner is used in the same room
as the air conditioner or heat pump, there is the danger
of oxygen deciency which could lead to an asphyxiation
hazard resulting in serious injury or death. Be sure to
ventilate the room sufciently to avoid this hazard.
• Safely dispose of the packing materials. Packing
materials, such as nails and other metal or wooden parts,
may cause stabs or other injuries.
• Tear apart and throw away plastic packaging bags so
that children will not play with them. Children playing with
plastic bags face the danger of death by suffocation.
