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, tele- •
phone 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 fi re. 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 fl ammable 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 qualifi ed 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 fi re.
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 defi ciency.
Use only specifi ed accessories and parts for installation •
work. Failure to use specifi ed parts may result in water
leakage, electric shocks, fi re, 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 insuffi cient strength may result in the unit
falling and causing injuries.
Take into account strong winds, typhoons, or earth- •
quakes when installing. Improper installation may result
in the unit falling and causing accidents.
Make sure that a separate power supply circuit is pro- •
vided for this unit and that all electrical work is carried
out by qualifi ed personnel according to local, state, and
national regulations. An insuffi cient power supply
capacity or improper electrical construction may lead to
electric shocks or fi re.
Make sure that all wiring is secured, that specifi ed wires •
are used, and that no external forces act on the terminal
connections or wires. Improper connections or installation may result in fi re.
1 English
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, fi re, 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 fi re.
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 fi re or
electric shock.
When installing or relocating the system, keep the •
refrigerant circuit free from substances other than the
specifi ed 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 specifi ed by Daikin are used, fi re or explosion may occur.
CAUTION
Do not touch the switch with wet fi ngers. Touching a •
switch with wet fi ngers 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 immedi- •
ately after operation as the refrigerant pipes may be hot
or cold, depending on the condition of the refrigerant
fl owing 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 fi ns are sharp enough to cut. •
To avoid injury wear glove or cover the fi ns 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 cylin- •
der 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 refriger- •
ant 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
fl uorescent lamps (inverter or rapid start types). Install
the indoor unit far away from fl uorescent 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 loca- •
tions:
(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 malfunc-
tion.
(d) Where fl ammable gas may leak, where there is car-
bon fi ber, or ignitable dust suspension in the air, or
where volatile fl ammables such as thinner or gaso-
line are handled. Operating the unit in such condi-
tions can cause a fi re.
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 fi re. 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 suffi cient 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 con- •
ventional refrigerants: gauge manifold, charge hose,
gas leak detector, reverse fl ow check valve, refrigerant
charge base, vacuum gauge, or refrigerant recovery
equipment.
If the conventional refrigerant and refrigeration oil are •
mixed in R410A, the refrigerant may deteriorate.
