Safety Considerations
Read these Safety Considerations for Operations
carefully before installing air conditioner or heat pump. Make
sure that the unit operates properly during the startup
operation. Instruct the customer on how to operate and
maintain the unit.
Inform customers that they should store this Operation
Manual with the Installation Manual for future reference.

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 will result in severe injury or death.
Turn o 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 will result in severe injury or death.
● For refrigerant leakage, consult your dealer.
Refrigerant gas is heavier than air and replaces oxygen. A
massive leak will result in oxygen depletion, especially in
basements, and an asphyxiation hazard will result 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
suciently to avoid this hazard.
● 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 suocation.
WARNING
● Contact your dealer for repair and maintenance. Improper repair
and maintenance could 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 could result in water leakage,
electric shock, and re.
● Never let the indoor unit or the remote controller get wet. Water
could result in an electric shock or a re.
● Never use ammable spray such as hair spray, lacquer, or paint
near the unit. Flammable spray could result in a re.
● When a fuse blows out, never replace it with one of incorrect
ampere ratings or dierent 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 and could result
in injury.
● Never inspect or service the unit by yourself. Contact a qualied
service person to perform this work.
● Turn o 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 could result in 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 could result in 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 could result in injury.
● Placing a ower vase or other containers with water or other
liquids on the unit could result in a shock or re if a spill occurs.
● Do not touch the air outlet or horizontal blades while the swing
ap is in operation could result in ngers getting 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.
