WARNING
• Ask your dealer or qualified personnel to carry out installation work. Do not try to install the
machine by yourself.
Improper installation may result in water leakage, electric shocks or fire.
• Perform installation work in accordance with this installation manual.
Improper installation may result in water leakage, electric shocks or fire.
• When installing the unit in a small room, take measures against to keep refrigerant concentration
from exceeding allowable safety limits in the event of refrigerant leakage.
Contact the place of purchase for more information. Excessive refrigerant in a closed ambient can lead to
oxygen deficiency.
• Be sure to use only the specified accessories and parts for installation work.
Failure to use the specified parts may result in water leakage, electric shocks, fire or the unit falling.
• Install the air conditioner on a foundation strong enough to withstand the weight of the unit.
A foundation of insufficient strength may result in the equipment falling and causing injuries.
1
• Carry out the specified installation work after taking into account strong winds, typhoons
or earthquakes.
Improper installation work may result in the equipment 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 laws and regulations and this installation
manual.
An insufficient power supply capacity or improper electrical construction may lead to electric shocks or fire.
• Make sure that all wiring is secured, the specified wires are used, and no external forces act on the
terminal connections or wires.
Improper connections or installation may result in fire.
• When wiring the power supply and connecting the remote controller wiring and transmission
wiring, position the wires so that the electric parts box lid can be securely fastened.
Improper positioning of the electric parts box lid may result in electric shocks, fire or the terminals
overheating.
• If the refrigerant gas leaks during installation, ventilate the area immediately.
Toxic gas may be produced if the refrigerant gas comes into contact with fire.
• After completing the installation work, check that the refrigerant gas does not leak.
Toxic gas may be produced if the refrigerant gas leaks into the room and comes into contact with a source
of fire, such as a fan heater, stove or cooker.
• Before touching electrical parts, turn off the unit.
• Ground the air conditioner. Do not connect the ground wire to gas or water pipes, lightning rod or
a telephone ground wire.
Incomplete grounding may result in electric shocks.
• Do not touch the switch with wet fingers.
Touching a switch with wet fingers can cause electric shock.
• Install an leak circuit breaker, as required.
If an leak circuit breaker is not installed, electric shock may result.
• Do not install the air conditioner in the following locations:
(a) where a mineral oil mist or an 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 result in a malfunction of the equipment.
(d) where flammable gases may leak, where there are carbon fiber or ignitable dust suspensions in the air,
or where volatile flammables such as thinner or gasoline are handled.
Operating the unit in such conditions may result in fire.
CAUTION
• While following the instructions in this installation manual, insulate piping in order to prevent condensation.
Improper piping insulation may result in water leakage and property damage.
• Be very careful about product transportation.
Some products use PP bands for packaging. Do not use any PP bands for a means of transportation.
It is dangerous.
• Safely dispose of the packing materials.
Packing materials, such as nails and other metal or wooden parts, may cause stabs or other injuries.
Tear apart and throw away plastic packaging bags so that children will not play with them. If children play
with a plastic bag which was not torn apart, they face the risk of suffocation.

NOTE
• Install the indoor and outdoor units, power supply wiring and connecting wires at least 3.5ft. away
from televisions or radios in order to prevent image interference or noise.
(Depending on the radio waves, a distance of 3.5ft. may not be sufficient enough to eliminate the noise.)
• Remote controller (wireless kit) transmitting distance can result shorter than expected in rooms
with electronic fluorescent lamps. (inverter or rapid start types)
Install the indoor unit as far away from fluorescent lamps as possible.
• This unit is a class A product.
In a domestic environment this product may cause radio interference in which case the user may be
required to take adequate measures.
• Dismantling of the unit, treatment of the refrigerant, oil and eventual other parts, should be done in
accordance with the relevant local and national regulations.
NOTE
The refrigerant R410A requires strict cautions for keeping the system clean, dry and tight.
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
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. Therefore we should take special
attention to check the tightness of the installation.
Read the chapter “Refrigerant piping work” carefully and follow these procedures correctly.
2. BEFORE INSTALLATION
2-1 CAUTION CONCERNING NEW REFRIGERANT SERIES
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.)
The indoor/outdoor unit is for R410A. See the catalog for indoor/outdoor unit models which can be
connected.
(Normal operation is not possible when connected to other units.)
2-2 PRECAUTIONS
• When moving the unit while removing it from the packing case, be sure to lift it by holding on to
the four hunger brackets without exerting any pressure on other parts, especially, the refrigerant
piping.
• Be sure to check the type of R410A refrigerant to be used before installing the unit. (Using an incorrect
refrigerant will prevent normal operation of the unit.)
• The accessories needed for installation must be retained in your custody until the installation work is completed. Do not discard them!
• Do not install or operate the unit in rooms mentioned below.
• Laden with mineral oil, or filled with oil vapor or spray like in kitchens. (Plastic parts may deteri-
orate which could eventually cause the unit to fall out of place, or could lead to leaks.)
• Where corrosive gas like sulfurous gas exists. (Copper pipe and brazed parts may corrode, which
could eventually lead to refrigerant leaks.)
• Where exposed to combustible gases and where volatile flammable gas like thinner or gasoline
is used. (Gas in the vicinity of the unit could ignite.)
• Where machines can generate electromagnetic waves. (Control system may malfunction.)
3
• Where the air contains high levels of salt such as that near the ocean and where voltage fluctuates greatly such as that in factories. Also in vehicles or vessels.
• Refer to the installation manual provided with the outdoor and the indoor unit.
If installed as a household appliance it could cause electromagnetic interference.
NOTE
• Be sure to read this manual before installing the indoor unit.
• Entrust installation to the place of purchase or a qualified serviceman. Improper installation could lead to
leaks and, in worse cases, electric shock or fire.
• Use only parts provided with the unit or parts satisfying required specifications. Unspecified parts could
cause the unit to fall out of place, or could lead to leaks and, in worse cases, electric shock or fire.
