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 into contact with 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 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 qualied 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 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 deciency.
• Use only specied accessories and parts for installation
work. Failure to use specied parts may result in water
leakage, electric shock, re, or the unit falling.
• Install the air conditioner or heat pump on a foundation
strong enough that it can withstand the weight of the unit.
A foundation of insufcient strength may result in the unit
falling and causing injuries.
• Ta ke into account strong winds, typhoons, or earthquakes
when installing. Improper installation may result in the unit
falling and causing accidents.
1 ■English
• Make sure that a separate power supply circuit is provided
for this unit and that all electrical work is carried out by
qualied personnel according to local, state, and national
regulations. An insufcient power supply capacity or
improper electrical construction may lead to electric shock
or re.
• Make sure that all wiring is secured, that specied wires
are used, and that no external forces act on the terminal
connections or wires. Improper connections or installation
may result in re.
• When wiring, position the wires so that the electrical
wiring box cover can be securely fastened. Improper
positioning of the electrical wiring box cover may result in
electric shock, re, 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 electric shock or 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 re or electric shock.
•
When installing or relocating the system, keep the refrigerant
circuit free from substances other than the specied
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
specied by Daikin are used, re or explosion may occur.
CAUTION
• Do not touch the switch with wet ngers. Touching a switch
with wet ngers can cause electric shock.
• Do not allow children to play on or around the unit to
prevent injury.
• The heat exchanger ns are sharp enough to cut. To avoid
injury wear gloves or cover the ns while working around
them.
• 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 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.
• 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.
Tight -- R410A does not contain any chlorine, does not
(b)
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 uorescent
lamps (inverter or rapid start types). Install the indoor unit
far away from uorescent 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.
• Do not install the air conditioner or heat pump 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 ammable gas may leak, where there is carbon
ber, or ignitable dust suspension in the air, or where
volatile ammables such as thinner or gasoline are
handled. Operating the unit in such conditions can
cause a re.
• Ta ke 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 re. Instruct the user to keep the
area around the unit clean.
NOTE
• Install the power supply and inter-unit wires for the indoor
and outdoor units at least 3.5ft away from televisions or
radios to prevent image interference or noise. Depending
on the radio waves, a distance of 3.5ft may not be
sufcient 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 ow 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 or heat pump is an appliance that
should not be accessible to the general public.
• As design pressure is 478 psi, the wall thickness of eld-
installed pipes should be selected in accordance with the
relevant local, state, and national regulations.
