DANGER
• Refrigerant gas is heavier than air and replaces oxygen. A massive leak could led 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.
1 English
• 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.
• 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 electrical componets box lid can be securely fastened.
Improper positioning of the electrical componets 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 (R-410A) 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 gloves or cover the fins when working around them.
English 2
• 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.
• Refrigerant R-410A 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 -- R-410A does not contain any chlorine, does not destroy the ozone layer, and does not
reduce the earth’s protection again harmful ultraviolet radiation. R-410A 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 R-410A 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 R-410A. See the catalog for indoor models that can be connected. Normal
operation is not possible when connected to other units.
• Remote controller (wireless kit) transmitting distance can be shorter than expected in rooms with
electronic fluorescent lamps (inverter or rapid start types). Install the indoor unit far away from fluorescent lamps as much as possible.
• 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 oper-
ation 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 televisions 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 R-410A, 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.

NOTE
The refrigerant R410A requires strict cautions for keeping the system clean, dry and tight.
A. Clean and dry
Foreign materials (including mineral oils such as SUNISO oil or moisture) should be prevented from
getting mixed 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 against harmful ultraviolet radiation.
R410A can contribute slightly to the greenhouse effect if it is released. Therefore we should take special attention to check the tightness of the installation.
Read the chapter “Refrigerant piping work” carefully and follow these procedures correctly.
2. BEFORE INSTALLATION
2-1 CAUTION CONCERNING NEW REFRIGERANT SERIES
• Since R410A is a mixed refrigerant, the required additional refrigerant must be charged in its liquid state. (If
the refrigerant is charged in a state of gas, its composition changes and the system will not work properly.)
The indoor/outside unit is for R410A. See the catalog for indoor/outside unit models which can be connected.
(Normal operation is not possible when connected to other units.)
2-2 PRECAUTIONS
• Hold the unit by the Hanging brackets (4 points) when opening the box and moving it, and do not lift it hold-
ing on to any other part especially the refrigerant piping.
• About installation of outside and indoor unit, refer to the installation manual provided with the outside and
the indoor unit.
• This unit, both indoor and outside, is suitable for installation in a commercial and light industrial environment.
If installed as a household appliance it could cause electromagnetic interference.
