• When wiring, position the wires so that the control
box cover can be securely fastened. Improper posi-
tioning of the control box cover may result in electric
shocks, re, or the terminals overheating.
• Before touching electrical parts, turn off the unit.
• This equipment can be installed with a Ground-Fault
Circuit Interrupter (GFCI). Although this is a recog-
nized measure for additional protection, with the
grounding system in North America, a dedicated GFCI
is not necessary.
• When installing or relocating the system, keep the
refrigerant circuit free from substances other than the
specied refrigerant (R410A) such as air. Any pres-
ence of air or other foreign substance in the refriger-
ant 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 protec-
tion 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.
• 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 refrig-
erant owing through the refrigerant piping, compres-
sor, 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 ns are sharp enough to cut. To avoid
injury, wear glove or cover the ns when working
around them.
• Install drain piping to proper drainage. Improper drain
piping may result in water leakage and property dam-
age.
• Insulate piping to prevent condensation.
• Be careful when transporting the product.
• Do not turn off the power supply immediately after
stopping operation. Always wait for at least 5 minutes
before turning off the power supply. 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 refrig-
erant must be charged in its liquid state. If the refriger-
ant is charged in a gaseous state, 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 opera-
tion is not possible when connected to other units.
• Handheld remote controller 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.
• 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 mal-
function.
(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.
NOTE
• Install the power supply and control wires for the
indoor and outdoor units at least 3.5 feet (1.0m) away
from televisions or radios to prevent image interfer-
ence or noise. Depending on the radio waves, a dis-
tance of 3.5 feet (1.0m) 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 is an appliance that should not be
accessible to the general public.
• As design pressure is 478 psi (3.3MPa), the wall
thickness of eld-installed pipes should be selected in
accordance with the relevant local, state, and national
regulations.
