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.
• 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 cover
can be securely fastened. Improper positioning of the control
box cover 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 outdoor unit terminal cover (panel). If the
terminal cover/panel is not installed properly, dust or water may
enter the outdoor 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.
1 English
• 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.
• 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 Work 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.
• 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 pro-
duced.
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 outdoor 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
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.

4. SELECTION OF INSTALLATION LOCATION
The refrigerant R410A itself is nontoxic, nonflammable and safe. If
the refrigerant should leak however, its concentration may exceed
the allowable limit depending on room size. Due to this it could be
necessary to take measures against leakage. Refer to the chapter
“Caution for refrigerant leaks”.
(1) Select a proper location satisfying the following requirements
with approval of the customer.
• Sufficient ventilation is secured.
• Adjacent houses are not annoyed.
• The foundation is strong enough to support the weight and with-
stand vibrations of the outdoor unit, and the location is safe and
allows horizontal installation.
• The outdoor unit is exposed to rain as less as possible.
• The space for installation and servicing is secured around the out-
door unit.
• The indoor/outdoor piping length and wiring length are within the
allowable range.
(2) When installing the outdoor unit in a location affected by strong
wind, pay special attention to the following items.
• If strong wind whose velocity is 11 mph or more blows to the out-
door unit from the air outlet side, the air flow rate of the outdoor
unit is reduced, the outlet air is sucked again (short-circuit), and
the following effect may be caused:
• The capacity is deteriorated.
• The adhered frost increases during heating operation.
• The operation is stopped by pressure rise.
• If excessive strong wind continuously blows from the air outlet side
of the outdoor unit, the fan may rotate in the reverse direction at
high speed, and lead to damage. Install the outdoor unit in reference to the following figures.
• Position the air outlet side toward the building wall, fence or
windbreak screen.
3. BEFORE INSTALLATION
<Bringing-in>
Bring in the outdoor unit slowly by holding the lugs provided on the left
and right sides as shown in the figures below.
(Take care so that hands and objects do not touch the fin on the rear.)

(3) When installing the outdoor unit in a location with heavy snow-
fall, pay special attention to the following items:
• Prepare strong foundation.
• Attach the snow hood (optional accessory).
• Remove the suction grill on the rear so that snow will not be accu-
mulated in the rear fin.
(4) When there is a possibility of short-circuit depending on the
ambient situation, use the wind direction adjusting plate
(optional accessory).
Make sure to use accessories and specified specification parts in the
installation work.

(5) The inverter type air conditioner may cause noise in electric
products.
When selecting an installation location, keep sufficient distance from the air conditioner unit and wiring to radios, personal computers, stereos, etc. as shown in the figure below.
In areas with weak electric waves, keep a distance of 120 in. or
more from the indoor remote controller, etc., put the power
cables and connection cables in conduit tubes, and ground the
conduit tubes.
