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 in contact with fire. 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 flammable 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 qualified 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 fire.
•
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 deficiency.
• Use only specified accessories and parts for installation work.
Failure to use specified parts may result in water leakage,
electric shocks, fire, 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 insufficient strength may result in the unit falling and causing injuries.
• Take into account strong winds, typhoons, or earthquakes
when installing. Improper installation may result in the unit
falling and causing accidents.
• Make sure that a separate power supply circuit is provided for
this unit and that all electrical work is carried out by qualified
personnel according to local state, and national regulations.
An insufficient power supply capacity or improper electrical
construction may lead to electric shocks or fire.
1 English
• Make sure that all wiring is secured, that specified wires are
used, and that no external forces act on the terminal connections or wires. Improper connections or installation may result in fire.
•
When wiring, position the wires so that the terminal box lid can be
securely fastened. Improper positioning of the terminal box lid
may result in electric shocks, fire, 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 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 refrigerant (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 specified by Daikin are used, fire or explosion may occur.
• 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. Operating 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 contact with electrical parts can cause malfunctions, smoke, or
fire. Instruct the customer to keep the area around the unit
clean.
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, depending 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 protection again harmful ultraviolet radiation. R-410A 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 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.
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 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 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 accessible to the general public.
• The wall thickness of field-installed pipes should be selected
in accordance with the relevant local, state, and national regulations.
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.
[DESIGN PRESSURE]
Since design pressure is 478 psi, the wall thickness of pipes should be
more carefully selected in accordance with the relevant local and
national regulations.
