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
...........
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
• 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.
WARNING
• Contact your dealer for repair and maintenance.
Improper repair and maintenance may result in water
leakage, electric shock, and re. Only use accessories
made by Daikin that are specically designed for use with
the equipment and have them installed by a professional.
• Contact your dealer to move and reinstall the air
conditioner or heat pump. Incomplete installation may
result in water leakage, electric shock, and re.
• Never let the indoor unit or the remote controller get wet.
Water can cause an electric shock or a re.
• Never use ammable spray such as hair spray, lacquer,
or paint near the unit. Flammable spray may cause a re.
• When a fuse blows out, never replace it with one of
incorrect ampere ratings or different wires. Always replace
any blown fuse with a fuse of the same specication.
• Never remove the fan guard of the unit. A fan rotating at
high speed without the fan guard is very dangerous.
• Never inspect or service the unit by yourself. Contact a
qualied service person to perform this work.
• Tu r n off all electrical power before doing any maintenance
to avoid the risk of serious electric shock; never sprinkle
or spill water or liquids on the unit.
• Do not touch the switch with wet ngers. Touching a
switch with wet ngers can cause electric shock.
• Do not allow children to play on or around the unit to
prevent injury.
•
The heat exchanger ns are sharp enough to cut. To avoid
injury wear gloves or cover the ns while working around them.
•
Do not put a nger or other objects into the air inlet or air
outlet. The fan is rotating at high speed and will cause injury.
• Check the unit foundation for damage on a continuous
basis, especially if it has been in use for a long time. If left
in a damaged condition the unit may fall and cause injury.
• Placing a ower vase or other containers with water or
other liquids on the unit could cause a shock or re if a
spill occurs.
• Do not touch the air outlet or horizontal blades while
the swing ap is in operation because ngers could get
caught and injured.
• Never touch the internal parts of the controller. Do not
remove the front panel because some parts inside are
dangerous to touch. To check and adjust internal parts,
contact your dealer.
CAUTION
