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 flammable 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 fire, 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 fire, 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 deficiency which could lead to an asphyxiation hazard resulting in serious injury or death. Be sure to ventilate the room sufficiently 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 fire. Only use accessories made by Daikin that are specifically 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 fire.

•Never let the indoor unit or the remote controller get wet. Water can cause an electric shock or a fire.

•Never use flammable spray such as hair spray, lacquer, or paint near the unit. Flammable spray may cause a fire.

•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 specification.

•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 qualified service person to perform this work.

•Turn 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 fingers.Touching a switch with wet fingers can cause electric shock.

•Do not allow children to play on or around the unit to prevent injury.

•The heat exchanger fins are sharp enough to cut.To avoid injury wear gloves or cover the fins while working around them.

•Do not put a finger 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 flower vase or other containers with water or other liquids on the unit could cause a shock or fire if a spill occurs.

•Do not touch the air outlet or horizontal blades while the swing flap is in operation because fingers 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

•Do not use the air conditioner or heat pump for any other purposes other than comfort cooling or heating.

Do not use the unit for cooling precision instruments, food, plants, animals or works of art.

•Do not place items under the indoor unit as they may be damaged by condensates that may form if the humidity is above 80% or if the drain outlet gets blocked.

•Before cleaning, stop the operation of the unit by turning the power off or by pulling the supply cord out from its receptacle. Otherwise, an electric shock and injury may result.

•Do not wash the air conditioner or heat pump with excessive water. An electric shock or fire may result.

•Avoid placing the controller in a spot splashed with water. Water entering the controller may cause an electric shock or damage the internal electronic parts.

•Do not operate the air conditioner or heat pump when using a room-fumigation type of insecticide.

Failure to observe this could cause the chemicals to be deposited in the unit and can endanger the health of those who are hypersensitive to chemicals.

•Do not turn off the power immediately after stopping operation. Always wait for at least 5 minutes before turning off the power. Otherwise, water leakage may occur.

•The appliance is not intended for use by young children or infirm persons without supervision.

•The remote controller should be kept away from children so they cannot play with it.

•Consult with the installation contractor for cleaning.

•Incorrect cleaning of the inside of the air conditioner or heat pump could make the plastics parts break and cause water leakage or electric shock.

•Do not touch the air inlet or aluminum fin of the air conditioner or heat pump as they can cut and cause injury.

•Do not place objects in direct proximity of the outdoor unit. Do not let leaves and other debris accumulate around the unit. Leaves are a hotbed for small animals which can enter the unit. Once inside the unit, animals can cause the unit to malfunction, and cause smoke or fire when they make contact with electrical parts.

NOTE

•Never press the button of the remote controller with a hard, pointed object.The remote controller may be damaged.

•Never pull or twist the electric wire of the remote controller. It may cause the unit to malfunction.

•Do not place appliances that produce open flames in places that are exposed to the airflow of the unit or under the indoor unit. It may cause incomplete combustion or deformation of the unit due to the heat.

•Do not expose the controller to direct sunlight.The LCD display can become discolored and may fail to display the data.

•Do not wipe the controller operation panel with benzene, thinner, chemical dust cloth, etc.The panel may get discolored or the coating can peel off. If it is heavily dirty, soak a cloth in water-diluted neutral detergent, squeeze it well and wipe the panel clean.Then wipe it with another dry cloth.

•Dismantling of the unit, disposal of the refrigerant, oil, and additional parts, should be done in accordance with the relevant local, state, and national regulations.

•Operate the air conditioner or heat pump in a sufficiently ventilated area and not surrounded by obstacles. Do not use the air conditioner or heat pump in the following places.

a.Places with a mist of mineral oil, such as cutting oil.

b.Locations such as coastal areas where there is a lot of salt in the air.

c.Locations such as hot springs where there is a lot of sulfur in the air.

d.Locations such as factories where the power voltage varies a lot.

e.In cars, boats, and other vehicles.

f.Locations such as kitchens where oil may splatter or where there is steam in the air.

g.Locations where equipment produces electromagnetic waves.

h.Places with an acid or alkaline mist.

i.Places where fallen leaves can accumulate or where weeds can grow.

•Take snow protection measures. Contact your dealer for the details of snow protection measures, such as the use of a snow protection hood.

•Do not attempt to do electrical work or grounding work unless you are licensed to do so. Consult with your dealer for electrical work and grounding work.

•Pay attention to operating sound. Be sure to use the following places:

a.Places that can sufficiently withstand the weight of the air conditioner or heat pump yet can suppress the operating sound and vibration.

b.Places where warm air from the air outlet of the outdoor unit or the operating sound of the outdoor unit does not annoy neighbors.

•Make sure that there are no obstacles close to the outdoor unit. Obstacles close to the outdoor unit may drop the performance of the outdoor unit or increase the operating sound of the outdoor unit.

•Consult your dealer if the air conditioner or heat pump in operation generates unusual noise.

•Make sure that the drainpipe is installed properly to drain water. If no water is discharged from the drainpipe while the air conditioner or heat pump is in the cooling mode, the drainpipe may be clogged with dust or dirt and water leakage from the indoor unit may occur. Stop operating the air conditioner or heat pump and contact your dealer.
