CAUTION
• Do not touch the switch with wet fingers. Touching a switch
with wet fingers may result in electric shock.
• Do not allow children to play on or around the unit or it
may result in injury.
• The heat exchanger fins are sharp enough to cut, and
may result in injury if improperly used. To avoid injury wear
glove or cover the fins when 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 flow-
ing through the refrigerant piping, compressor, and other
refrigerant cycle parts. It may result in your hands get-
ting 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.
• 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 result.
• 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 pre-
vented 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 and follow the
procedures.
• Since R410A is a blend, the required additional refriger-
ant 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 fluores-
cent 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. This unit is for
indoor use.
• Do not install the air conditioner or heat pump in the fol-
lowing locations:
(a) Where a mineral oil mist or oil spray or vapor is pro-
duced, for example, in a kitchen.
Plastic parts may deteriorate and fall off and thus may
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.
English
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 car-
bon 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
may result in a fire.
• Take adequate measures to prevent the outdoor unit from
being used as a shelter by small animals. Small animals
making contact with electrical parts may result in malfunc-
tions, smoke, or fire. Instruct the customer to keep the
area around the unit clean.
NOTE
• Install the power supply and transmission wires for the in-
door and outdoor units at least 3.5 ft. (1 m) away from tele-
visions or radios to prevent image interference or noise.
Depending on the radio waves, a distance of 3.5 ft. (1 m)
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 con-
ventional 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 R410A, the refrigerant result in deterioration.
• This air conditioner or heat pump is an appliance that
should not be accessible to the general public.
• As design pressure is 478 psi (3.3 MPa), the wall thick-
ness of field-installed pipes should be selected in accor-
dance with the relevant local, state, and national regula-
tions.

Codes and Regulations

This product is designed and manufactured to comply with
national codes. Installation in accordance with such codes
and/or prevailing local codes/regulations is the responsibility
