•
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 sub-
stance in the refrigerant circuit can cause an abnormal pres-
sure rise or rupture, resulting in injury.
•
Do not change the setting of the protection devices. If the pres-
sure switch, thermal switch, or other protection device is
shorted and operated forcibly, or parts other than those speci-
fied 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, depend-
ing 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 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 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 pro-
tection again harmful ultraviolet radiation. R-410A can con-
tribute to the greenhouse effect if it is released. Therefore
take proper measures to check for the tightness of the refrig-
erant piping installation. Read the chapter Refrigerant Pip-
ing 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 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. Operat-
ing 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 con-
tact 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 addi-
tional 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 accessi-
ble to the general public.
•
The wall thickness of field-installed pipes should be selected in
accordance with the relevant local, state, and national regula-
tions.

INTRODUCTION
1.
This series uses R410A new refrigerant. Be absolutely sure to com-
ply with “
7. PRECAUTIONS ON REFRIGERANT PIPING
”, because
even greater caution is needed to prevent impurities from entering
R410A (mineral oils and water).
2.
The design pressure is 478PSI (3.3MPa), which means that piping
may be thicker than conventionally, so please refer to “
7. PRECAU-
TIONS ON REFRIGERANT PIPING
”.
3.
This is a mixed refrigerant, so charge as a liquid when adding refrig-
erant.
(If charged as a gas, the composition of the refrigerant may change,
preventing normal operation.)
4.
The indoor unit must use R410A. See the catalog for indoor unit
models which can be connected. (Normal operation is not possible
when connected to other units.)
5.
The power supply of this series is single-phase, 208/230V, 60Hz.
