DANGER
• Refrigerant gas is heavier than air and replaces oxygen. A massive leak can lead to oxygen depletion,
especially in basements, and an asphyxiation hazard could occur leading to serious injury or death.
• Do not ground units to water pipes, gas pipes, telephone wires, or lightning rods as incomplete grounding
can cause a severe shock hazard resulting in severe injury or death. Additionally, grounding to gas pipes
could cause a gas leak and potential explosion causing severe injury or death.
• If refrigerant gas leaks during installation, ventilate the area immediately. Refrigerant gas may produce toxic
gas if it comes in contact with fire. Exposure to this gas could cause severe injury or death.
• After completing the installation work, check that the refrigerant gas does not leak throughout the system.
• Do not install unit in an area where flammable materials are present due to risk of explosions that can cause
serious injury or death.
English 1
• 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 suffocation.
WARNING
• Only qualified personnel must carry out the installation work. Installation must be done in accordance with
this installation manual. Improper installation may result in water leakage, electric shock, or fire.
• When installing the unit in a small room, take measures to keep the refrigerant concentration from exceeding allowable safety limits. Excessive refrigerant leaks, in the event of an accident in a closed ambient
space, can lead to oxygen deficiency.
• Use only specified accessories and parts for installation work. Failure to use specified parts may result in
water leakage, electric shocks, fire, or the unit falling.
• Install the air conditioner on a foundation strong enough that it can withstand the weight of the unit. A foundation of insufficient strength may result in the unit falling and causing injuries.
• Take into account strong winds, typhoons, or earthquakes when installing. Improper installation may result
in the unit falling and causing accidents.
• Make sure that a separate power supply circuit is provided for this unit and that all electrical work is carried
out by qualified personnel according to local, state, and national regulations. An insufficient power supply
capacity or improper electrical construction may lead to electric shocks or fire.
• Make sure that all wiring is secured, that specified wires are used, and that no external forces act on the terminal connections or wires. Improper connections or installation may result in fire.
When wiring, position the wires so that the control box lid can be securely fastened. Improper positioning of
•
the control box lid may result in electric shocks, fire, or the terminals overheating.
• Before touching electrical parts, turn off the unit.
• Be sure to install a ground fault circuit interrupter if one is not already available. This helps prevent electrical
shocks or fire.
• Securely fasten the outside unit terminal cover (panel). If the terminal cover/panel is not installed properly,
dust or water may enter the outside unit causing fire or electric shock.
• When installing or relocating the system, keep the refrigerant circuit free from substances other than the
specified refrigerant (R410A) such as air. Any presence of air or other foreign substance in the refrigerant
circuit can cause an abnormal pressure rise or rupture, resulting in injury.
• Do not change the setting of the protection devices. If the pressure switch, thermal switch, or other protection device is shorted and operated forcibly, or parts other than those specified by Daikin are used, fire
or explosion may occur.
CAUTION
• 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.
• Do not touch the refrigerant pipes during and immediately after operation as the refrigerant pipes may be
hot or cold, depending on the condition of the refrigerant flowing through the refrigerant piping, compressor,
and other refrigerant cycle parts. Your hands may suffer burns or frostbite if you touch the refrigerant pipes.
To avoid injury, give the pipes time to return to normal temperature or, if you must touch them, be sure to
wear proper gloves.
• Heat exchanger fins are sharp enough to cut.
To avoid injury wear glove or cover the fins when working around them.
• Install drain piping to proper drainage. Improper drain piping may result in water leakage and property damage.
• Insulate piping to prevent condensation.
• Be careful when transporting the product.
• 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.
• Do not use a charging cylinder. Using a charging cylinder may cause the refrigerant to deteriorate.
2 English
• Refrigerant R410A in the system must be kept clean, dry, and tight.
(a) Clean and Dry -- Foreign materials (including mineral oils such as SUNISO oil or moisture) should be
prevented from getting into the system.
(b) Tight -- R410A does not contain any chlorine, does not destroy the ozone layer, and does not reduce
the earth’s protection again harmful ultraviolet radiation. R410A can contribute to the greenhouse effect
if it is released. Therefore take proper measures to check for the tightness of the refrigerant piping
installation. Read the chapter Refrigerant Piping and follow the procedures.
• Since R410A is a blend, the required additional refrigerant must be charged in its liquid state. If the refrigerant is charged in a state of gas, its composition can change and the system will not work properly.
• The indoor unit is for R410A. See the catalog for indoor models that can be connected. Normal operation
is not possible when connected to other units.
• Indoor units are for indoor installation only. Outdoor units can be installed either outdoors or indoors.
• Do not install the air conditioner in the following locations:
(a) Where a mineral oil mist or oil spray or vapor is produced, for example, in a kitchen.
Plastic parts may deteriorate and fall off or result in water leakage.
(b) Where corrosive gas, such as sulfurous acid gas, is produced.
Corroding copper pipes or soldered parts may result in refrigerant leakage.
(c) Near machinery emitting electromagnetic waves.
Electromagnetic waves may disturb the operation of the control system and cause the unit to malfunction.
(d) Where flammable gas may leak, where there is carbon fiber, or ignitable dust suspension in the air, or
where volatile flammables such as thinner or gasoline are handled. Operating the unit in such conditions can cause a fire.
• Take adequate measures to prevent the outside unit from being used as a shelter by small animals. Small
animals making contact with electrical parts can cause malfunctions, smoke, or fire. Instruct the customer
to keep the area around the unit clean.
NOTE
• Install the power supply and control wires for the indoor and outdoor units at least 3.5 feet away from tele-
visions or radios to prevent image interference or noise. Depending on the radio waves, a distance of
3.5 feet may not be sufficient to eliminate the noise.
• Dismantling the unit, treatment of the refrigerant, oil and additional parts must be done in accordance with
the relevant local, state, and national regulations.
Do not use the following tools that are used with conventional refrigerants: gauge manifold, charge hose, gas leak
•
detector, reverse flow check valve, refrigerant charge base, vacuum gauge, or refrigerant recovery equipment.
• If the conventional refrigerant and refrigerator oil are mixed in R410A, the refrigerant may deteriorate.
• This air conditioner is an appliance that should not be accessible to the general public.
• The wall thickness of field-installed pipes should be selected in accordance with the relevant local, state,
and national regulations.
2. BEFORE INSTALLATION
Do not exert pressure on the resin parts when opening the unit or when moving it after opening.
Be sure to check the type of R410A refrigerant to be used before doing any work. (Using an incorrect
refrigerant will prevent normal operation of the unit.)
• When opening the unit or moving it after opening, be sure to lift it by holding on to the lifting lugs without
exerting any pressure on other parts, especially, drain piping, and other resin parts.
• Decide upon a line of transport.
• Leave the unit inside its packaging while moving, until reaching the installation site. Use a sling of soft mate-
rial, where unpacking is unavoidable or protective plates together with a rope when lifting, to avoid damage
or scratches to the unit.
• Refer to the installation manual of the outdoor unit for items not described in this manual.
• Do not dispose of any parts necessary for installation until the installation is complete.
