IMPORTANT!
Please Read Before Starting
This air conditioning system meets strict safety and operating
standards. As the installer or service person, it is an important
part of your job to install or service the system so it operates
safely and efficiently.
For safe installation and trouble-free operation, you
must:
G
Carefully read this instruction booklet before beginning.
G
Follow each installation or repair step exactly as shown.
G
Observe all local, state, and national electrical codes.
G
Pay close attention to all warning and caution notices
given in this manual.
This symbol refers to a hazard
WARNING
CAUTION
or unsafe practice which can
result in severe personal injury
or death.
This symbol refers to a hazard
or unsafe practice which can
result in personal injury or product or property damage.
If Necessary, Get Help
These instructions are all you need for most installation
sites and maintenance conditions. If you require help for a
special problem, contact our sales/service outlet or your
certified dealer for additional instructions.
In Case of Improper Installation
The manufacturer shall in no way be responsible for improper installation or maintenance service, including failure to
follow the instructions in this document.
SPECIAL PRECAUTIONS
WARNING
• Do not supply power to the unit until all wiring and tubing
are completed or reconnected and checked.
• Highly dangerous electrical voltages are used in this
system. Carefully refer to the wiring diagram and these
instructions when wiring. Improper connections and
inadequate grounding can cause accidental injury or
death.
• Ground the unit following local electrical codes.
• Connect all wiring tightly. Loose wiring may cause overheating at connection points and a possible fire hazard.
When Transporting
Be careful when picking up and moving the indoor and outdoor units. Get a partner to help, and bend your knees when
lifting to reduce strain on your back. Sharp edges or thin aluminum fins on the air conditioner can cut your fingers.
When Wiring
ELECTRICAL SHOCK CAN CAUSE SEVERE
PERSONAL INJURY OR DEATH. ONLY A
QUALIFIED, EXPERIENCED ELECTRICIAN
SHOULD ATTEMPT TO WIRE THIS SYSTEM.
When Installing…
…In a Ceiling or Wall
Make sure the ceiling/wall is strong enough to hold the
unit’s weight. It may be necessary to construct a strong
wood or metal frame to provide added support.
…In a Room
Properly insulate any tubing run inside a room to prevent
“sweating” that can cause dripping and water damage to
walls and floors.
When Connecting Refrigerant Tubing
• Do not add any refrigerant, air, or substance into the
refrigeration circuit other than the designated refrigerant
(R410A). Adding anything other than the specified refrigerant may cause the pressure to rise excessively in the
refrigeration circuit, rupturing the circuit and causing injury
or damage.
• Use all-new tubing and flare nuts to make the tubing connections. Using any previous parts (from R22-based systems) may result in damage to the equipment, and may
lead to the refrigeration circuit rupturing, causing a serious accident.
• Apply refrigerant lubricant to the matching surfaces of
the flare and union tubes before connecting them, then
tighten the nut with a torque wrench for a leak-free
connection.
• Check carefully for leaks before starting the test run.
When Servicing
• Turn the power OFF at the main power box (mains) before
opening the unit to check or repair electrical parts and
wiring.
• Keep your fingers and clothing away from any moving
parts.
• Clean up the site after you finish, remembering to check
that no metal scraps or bits of wiring have been left inside
the unit being serviced.
Others
CAUTION
• Ventilate any enclosed areas when installing or testing
the refrigeration system. Escaped refrigerant gas, on
contact with fire or heat, can produce dangerously
toxic gas.
• Confirm upon completing installation that no refrigerant
gas is leaking. If escaped gas comes in contact with a
stove, gas water heater, electric room heater or other heat
source, it can produce dangerously toxic gas.

1-3. Optional Copper Tubing Kit
Copper tubing for connecting the outdoor unit to the
indoor unit is available in kits which contain the narrow
and wide tubing, fittings and insulation. Consult your
nearest sales outlet or A/C workshop.
1-4. Type of Copper Tube and Insulation Material
2. Foamed polyethylene insulation for the specified
copper tubes as required to precise length of tubing.
Wall thickness of the insulation should be not less
than 5/16" (8 mm).
3. Use insulated copper wire for field wiring. Wire size
varies with the total length of wiring. Refer to 3-6.
Wiring Instructions for details.
If you wish to purchase these materials separately from
a local source, you will need:
1. Deoxidized annealed copper tube for refrigerant tubing as detailed in Table 2.
Cut each tube to the appropriate lengths 1' to 1'4"
(30 cm to 40 cm) to dampen vibration between units.

WARNING
To prevent abnormal heat generation
and the possibility of fire, do not
place obstacles, enclosures and
grilles in front of or surrounding the
air conditioner in a way that may
block air flow.
AVOID:
G direct sunlight.
G nearby heat sources that may affect performance of the
unit.
G areas where leakage of flammable gas may be expected.
G placing or allowing any obstructions near the A/C inlet or
outlet.
G installing in rooms that contain instant-on (rapid-start)
fluorescent lamps. (These may prevent the A/C from
receiving signals.)
G places where large amounts of oil mist exist.
G installing in locations where there are devices that
generate high-frequency emissions.
DO:
G select an appropriate position from which every corner of
the room can be uniformly cooled. (High on a wall is best.)

No additional charge of compressor oil is necessary.
2-2. Embedding the Tubing and Wiring
G Before beginning embedding installation work, consult
fully with agencies or offices related to the building’s
foundation, construction, electricity, and water.
G Wait to make connections to the embedded portion.
Each connection step is described later in this
manual.
G Securely cover the end of the embedded tubing to
prevent intrusion of dirt or moisture.
G If an embedded tube is to be left for a long time, fill
the tube with nitrogen and seal both ends securely.
If a tube is left open for an extended time, moisture in
the air inside the tubing may condense into water
droplets, and lead to water contamination of the refrigerant circuit.
G In order to prevent insulation breakdown and ground
faults, do not allow wiring ends to come in contact with
rainwater, or be subjected to condensation or dew.
G Apply sufficient thermal insulation to the refrigerant
tubing and drain pipes.

3. How to Install the Indoor Unit
3-1. Remove the Rear Panel from the Unit
(1) Remove and discard the set screw on the rear
panel. (Fig. 6)
(2) Press the 2 LL marks on the frame cover and disen-
gage the stationary tabs from the frame. (Fig. 7)
(3) Remove the rear panel.
Set screw only for transportation
NOTE
Tubing can be extended in 5 directions as shown in Fig.
8. Select the direction you need providing the shortest
run to the outside unit.
G When left tubing is to be done, switch the drain hose
and drain cap. (For details, refer to “Switching drain
hose and drain cap” on page 14.)
3-2. Make a Hole
(1) Place the rear panel from the indoor unit on the wall
at the location selected. Make sure the panel is horizontal, using a carpenter’s level or tape measure to
measure down from the ceiling. Wait until after cutting the hole before attaching the rear panel to the
wall.
(2) Determine which side of the unit you should make
the hole for tubing and wiring. (Fig. 9a or 9b)
NOTE
In the case of left-rear tubing, use the measurement
points from the edge of the rear panel for precise placement of the hose outlet. (Fig. 9a or 9b)
(3) Before making the hole, check carefully that no
studs or pipes are directly run behind the spot to be
cut.
