READ THESE INSTRUCTIONS CAREFULLY BEFORE INSTALLATION. KEEP THIS MANUAL IN A HANDY PLACE FOR FUTURE REFERENCE.
IMPROPER INSTALLATION OR ATTACHMENT OF EQUIPMENT OR ACCESSORIES COULD RESULT IN ELECTRIC SHOCK, SHORT-CIRCUIT, LEAKS, FIRE OR
OTHER DAMAGE TO THE EQUIPMENT. BE SURE ONLY TO USE ACCESSORIES MADE BY DAIKIN WHICH ARE SPECIFICALLY DESIGNED FOR USE WITH THE EQUIPMENT AND HAVE THEM INSTALLED BY A PROFESSIONAL.
IF UNSURE OF INSTALLATION PROCEDURES OR USE, ALWAYS CONTACT YOUR DAIKIN DEALER FOR ADVICE AND INFORMATION.
SAFETY CONSIDERATIONS
Please read these safety precautions carefully before installing the air conditioning equipment and be sure to install it correctly. After completing the installation, make sure that the unit operates properly during the start-up operation. Please instruct the customer on how to operate the unit and keep it maintained.
Inform customers that they should store this operation manual along with the installation manual for future reference. This air conditioner comes under the term "appliances not accessible to the general public".
The safety considerations listed here are divided into the following types and cover very important topics, so be sure to follow them carefully.
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 potentiality 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 situation that may result in equipment or property-damage-only accidents.
Keep these warning sheets handy so that you can refer to them when needed.
If this equipment is transferred to a new user, make sure to hand over this operation manual to the new user.
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 such as smoke or fire could result in severe injury or death.
Turn off the power and contact your dealer immediately for instructions.
■If refrigerant gas comes in contact with fire such as from a fan, heater, stove or cooking device, it may produce toxic gases. Exposure to these gases could cause severe injury or death.
■If there is a 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, 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 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 can not play with them. Children playing with plastic bags face the danger of death by suffocation.

WARNING
■It is not good for your health to expose your body to the air flow for a long time.
■Ask your dealer
■for installation of the air conditioner.
■for improvement, repair, and maintenance of the air conditioner.
■to move and reinstall the air conditioner.
Incomplete installation performed by yourself may result in a water leakage, electric shock or fire.
■Improper installation or attachment of equipment or accessories could result in electric shock, short-circuit, leaks, fire or other damage to the equipment. Be sure only to use accessories made by Daikin which are specifically designed for use with the equipment and have them installed by a professional.
■Never let the indoor unit or the remote controller get wet.
It may cause an electric shock or a fire.
■Never use a flammable spray such as hair spray, lacquer or paint near the unit.
These products may cause a fire.
■Never replace a fuse with a fuse of wrong ampere rating or wires when a fuse is blown.
Not replacing a blown fuse by a fuse of correct ampere rating may cause the unit to break down or cause a fire.
■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.
Ask an authorized service person to perform this work.
■Cut off all electric waves before maintenance.
■To avoid the risk of serious electrical shock, never sprinkle or spill water or liquids on the unit.
Placing a flower vase or other containers with water or other liquids on the unit could result in a shock hazard or fire if a spill occurs.
■Operating the air conditioner with wet hands could result in a shock hazard.
■Do not allow children to play on or around the unit as they could be injured.
■Check the unit stand for damage on a continuous basis.
If left in a damaged condition the unit may fall and cause 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.
■Do not touch the air outlet or the horizontal flaps while the swing flap is in operation as fingers may get caught and injured.
■Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric shocks or fire.
■Never touch the internal parts of the controller.
Do not remove the front panel because some parts inside the controller are dangerous to touch. In addition, some parts may be damaged. For checking and adjusting the internal parts, contact your dealer.
CAUTION
■Do not use the air conditioner for other purposes.
In order to avoid any quality deterioration, do not use the unit for cooling precision instruments, food, plants, animals or works of art.
■Do not place items under the indoor unit which may be damaged by water.
Condensation may form if the humidity is above 80% or if the drain outlet gets blocked.
■Avoid placing the controller in a spot splashed with water.
Water coming inside the unit may cause an electric leak or may damage the internal electronic parts.
■Do not operate the air conditioner when using a room fumigation - type insecticide.
Chemicals from the insecticide deposited into the unit, could endanger the health of those who are hypersensitive to chemicals.
■Do not turn off the power immediately after stopping operation.
Always wait at least 5 minutes before turning off the power. Otherwise, water leakage and trouble may occur.
■The appliance is not intended for use by young children or infirm persons without supervision.
■The remote controller must be installed in such a way that children can not play with it.
■Consult with the installation contractor for cleaning the inside of the air conditioner.
Wrong cleaning may be the cause for plastic parts to break, water leakage or electric shock.
■Do not touch the air inlet or aluminium fins of the air conditioner.
Otherwise, injury may be caused.
■Do not place objects in direct proximity of the outdoor unit and do not let leaves and other debris accumulate around the unit.
Leaves are a hotbed for small animals which can enter the unit. Once in the unit, such animals can cause malfunctions, smoke or fire when contact with electrical parts.

■Dismantling of the unit, treatment of the refrigerant, oil, and eventual other parts, should be done in accordance with the relevant local and national regulations.
■Do not dry the filter by exposing it to direct sunlight or warming it using fire, etc. Doing so can result in the deformation of the filter.
BEFORE INSTALLATION
■When moving the unit while removing it from the carton box, be sure to lift it by holding on to the four lifting lugs without exerting any pressure on other parts, especially on the swing flap, the refrigerant piping, drain piping, and other resin parts.
■Leave the unit inside its packaging until you reach the installation site. Where unpacking is unavoidable, use a sling of soft material or protective plates together with a rope when lifting, this to avoid damage or scratches to the unit.
■Especially, do not unfasten the packing case (top) guarding the switch box until suspending the unit.
■Refer to the installation manual of the outdoor unit for items not described in this manual.
■Caution concerning refrigerant series R410A:
The connectable outdoor units must be designed exclusively for R410A.
