CAUTION
• Install drain piping according to this installation manual to
ensure good drainage, and insulate the piping to prevent
condensation.
Improper drain piping may cause water leakage, make the
furniture get wet.
•
Install the air conditioner, power supply wiring, remote
controller wiring and transmission wiring at least 1 meter
away from televisions or radios to prevent image interference
or noise.
(Depending on the radio waves, a distance of 1 meter may
not be
sufficient to eliminate the noise.)
•
Install the indoor unit as far as possible from fluorescent
lamps.
If a wireless remote controller kit is installed, the transmission
distance may be shorter in a room where an electronic lighting
type (inverter or rapid start type)
fluorescent lamp is installed.
• Do not install the air conditioner in places such as the
following:
1. Where there is mist of oil, oil spray or vapour for example
a kitchen.
Resin parts may deteriorate, and fall out or water may
leak.
2. Where corrosive gas, such as sulfurous acid gas, is
produced.
Corrosion of copper pipings or brazed parts may cause
the refrigerant to leak.
3. Where there is machinery which emits electromagnetic
waves.
Electromagnetic waves may disturb the control system,
and cause malfunction of the equipment.
4. Where gases may leak, where carbon
or ignitable dust is suspended in the air or where volatile
such as thinner or gasoline, are handled.
If the gas should leak and remain around the air condi-
tioner, it may cause ignition.
• The air conditioner is not intended for use in a potentially
explosive atmosphere.
•
Pay careful attention when transporting the product.
Carry the product by the handle sections indicated on the
packaging material.
Do not hold the PP band since the PP band can become
loose and may result in danger.
• Do not touch the heat exchanger fin s.
Inadvertently touching the fins can cause injury.
2. BEFORE INSTALLATION
When unpacking the indoor unit or moving the unit after
unpacked, hold the hangers (4 places) and do not apply
force to other parts (particularly refrigerant piping, drain
piping).
• Make sure to check in advance that the refrigerant to be
used for installation work is R410A.
(The air conditioner will not properly operate if a wrong
refrigerant is used.)
• For installation of the outdoor unit, refer to the installation
manual attached to the outdoor unit.
• Do not throw away the accessories until the installation work
is completed.
•
After the indoor unit is carried into the room, to avoid the
indoor unit from getting damaged, take measures to protect
the indoor unit with packing materials.
(1) Determine the route to carry the unit into the room.
(2) Do not unpack the unit until it is carried to the installa-
tion location.
Where unpacking is unavoidable, use a sling of soft
material or protective plates together with a rope when
lifting, to avoid damage or scratches to the indoor unit.
• Have the customer actually operate the air conditioner while
looking at the operation manual.
Instruct the customer how to operate the air conditioner
(particularly cleaning of the air
filter s, operation pro cedures,
and temperature adjustment).
• When wiring between the indoor and outdoor units, and
wiring the power supply, form the wirings orderly so that the
control box lid can be securely fastened.
If the control box lid is not in place, overheating of the
terminals, electric shocks or a
fire may be caused.
• If refrigerant gas leaks during installation work, ventilate the
area immediately.
Toxic gas may be produced if refrigerant gas comes into
contact with a
fir e.
• After completing the installation work, check to make sure
that there is no leakage of refrigerant gas.
Toxic gas may be produced if refrigerant gas leaks into the
room and comes into contact with a source of a
fir e, such as
a fan heater, stove or cooker.
•
•
Never directly touch any accidental leaking refrigerant. This
could result in severe wounds caused by frostbite.
Do not allow children to climb on the outdoor unit and avoid
placing objects on the unit.
Injury may result if the unit becomes loose and falls.
•
•
•
Make sure to provide for adequate measures in order to prevent
that the outdoor unit be used as a shelter by small animals.
Small animals making contact with electrical parts can cause
malfunctions, smoke or fire. Please instruct the customer to
keep the area around the unit clean.
Install in a machine room that is free of moisture. The unit is
designed for indoor use.
Disposal requirements
Dismantling of the unit, treatment of the refrigerant, of oil and of
other parts must be done in accordance with relevant local and
national legislation.

SPECIAL NOTICE PRODUCT
The refrigerant R410A requires that strict precautions be
observed for keeping the system clean, dry and tightly sealed.
A. Clean and dry
Strict measures must be taken to keep impurities
(including SUNISO oil and other mineral oils as well as
moisture) out of the system.
B. Tightly sealed
R410A contains no chlorine, does not destroy the ozone
layer and so does not reduce the earth's protection against
harmful ultraviolet radiation. R410A will contribute only slightly
to the greenhouse effect if released into the atmosphere.
Since design pressure is 4.0 MPa or 40 bar (for R407C units:
3.3 MPa or 33 bar), the thickness of pipes must be greater
than previously. Since R410A is a mixed refrigerant, the
required additional refrigerant must be charged in its liquid state.
(If the system is charged with refrigerant in its gaseous state,
due to composition change, the system will not function
normally). The indoor unit is designed for R410A use.
See the catalogue for indoor unit models that can be
connected. (Normal operation is not possible when connecting
units that are originally designed for other refrigerants.)
