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.
22
• 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 into 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.
FXMQ-P
EDUS39-900A-F4
• 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.
Installation
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.
• Install drain piping to proper drainage. Improper
drain piping may result in water leakage and
property damage.
• Insulate piping to prevent condensation.
• 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.
• Be careful when transporting the product.
• 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.
• Do not use a charging cylinder. Using a charging
cylinder may cause the refrigerant to deteriorate.
• When wiring, position the wires so that the terminal
box lid can be securely fastened. Improper
positioning of the terminal box lid may result in
electric shocks, fire, or the terminals overheating.
• Before touching electrical parts, turn off the unit.
• It is recommended 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
FXMQ-P
• 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.
• 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.
This unit is for indoor use.
23

EDUS39-900A-F4
• 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.
10.3

• 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.

condensation. (Material: Glass wool or styrene foam;
Thickness: 31/32 in.)
• Be sure to attach the field supply air filter to the air inlet of
the unit or field supply inlet in the air passage on the air
suction side. (Be sure to select an air filter with a duct
collection efficiency of 50 weight percent.)
• Explain the operation and washing methods of the locally
procured components (i.e., the air filter, air inlet grille, and
air outlet grille) to the customer.
