• Do not touch the refrigerant pipes during and imme-
diately after operation as the refrigerant pipes may be
hot or cold, depending on the condition of the refriger-
ant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 cylin-
der 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 min-
eral 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 mea-
sures 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 state of gas, its composition can
change and the system will not work properly.
• TheindoorunitisforR410A.Seethecatalogforin-
door 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
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 or heat pump 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.
• Take adequate measures to prevent the outdoor unit
from being used as a shelter by small animals. Small
animals making contact with electrical parts can
causemalfunctions,smoke,orre.Instructthecus-
tomer to keep the area around the unit clean.
NOTE
• Install the power supply and transmission wires for
the indoor and outdoor units at least 3.5 feet away
from televisions or radios to prevent image interfer-
ence or noise. Depending on the radio waves, a dis-
tanceof3.5feetmaynotbesufcient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owcheckvalve,refriger-
ant charge base, vacuum gauge, or refrigerant recov-
ery equipment.
• If the conventional refrigerant and refrigerator oil are
mixedinR410A,therefrigerantmaydeteriorate.
• This air conditioner or heat pump is an appliance that
should not be accessible to the general public.
• Asdesignpressureis478psi,thewallthicknessof
eld-installedpipesshouldbeselectedinaccordance
with the relevant local, state, and national regulations.
