• Make sure that all wiring is secured, that specified wires are
used, and that no external forces act on the terminal connec-
tions or wires. Improper connections or installation may re-
sult in fire.
• When wiring, position the wires so that the electric parts box
lid can be securely fastened. Improper positioning of the elec-
tric parts box lid may result in electric shocks, fire, or the ter-
minals 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 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 refriger-
ant (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 spec-
ified 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 af-
ter operation as the refrigerant pipes may be hot or cold, de-
pending 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 re-
turn 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 opera-
tion. 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
protection again harmful ultraviolet radiation. R-410A can
contribute to the greenhouse effect if it is released. There-
fore take proper measures to check for the tightness of the
refrigerant piping installation. Read the chapter Refriger-
ant 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 mod-
els 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 vol-
atile 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 be-
ing 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.
NOTE
• Install the power supply and control wires for the indoor and out-
door units at least 3.5 feet away from televisions or radios to pre-
vent 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 lo-
cal, 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 acces-
sible to the general public.
• The wall thickness of field-installed pipes should be selected
in accordance with the relevant local, state, and national reg-
ulations.
1-2 Special notice of product
[CLASSIFICATION]
This air conditioner comes under the term “appliances not accessible to
the general public”.
[REFRIGERANT]
VRVIII System use R410A refrigerant.
• The refrigerant R410A requires strict cautions for keeping the sys-
tem clean, dry and tight.
Read the chapter “REFRIGERANT PIPING” carefully and follow
these procedures correctly.
A. Clean and dry
Foreign materials (including mineral oils such as SUNISO oil or
moisture) should be prevented from getting mixed into the system.
B. Tight
Take care to keep the system tight when installing.
R410A does not contain any chlorine, does not destroy the ozone
layer, and does not reduce the earth’s protection against harmful
ultraviolet radiation.
R410A can contribute slightly to the greenhouse effect if it is
released.
• Since R410A is a mixed refrigerant, the required additional refrigerant
must be charged in its liquid state. If the refrigerant is charged in a state
of gas, its composition changes and the system will not work properly.
