property damage.
When Wiring
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 Installing…
Select an installation location which is rigid and strong
enough to support or hold the unit, and select a location for
easy maintenance.
…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.
Keep the fire alarm and the air
CAUTION
…In Moist or Uneven Locations
Use a raised concrete pad or concrete blocks to provide a
solid, level foundation for the outdoor unit. This prevents
water damage and abnormal vibration.
…In an Area with High Winds
Securely anchor the outdoor unit down with bolts and a
metal frame. Provide a suitable air baffle.
…In a Snowy Area (for Heat Pump-type Systems)
Install the outdoor unit on a raised platform that is higher
than drifting snow. Provide snow vents.
outlet at least 5 feet (1.5 m) away
from the unit.
When Connecting Refrigerant Tubing
•Ventilate the room well, in the event that is refrigerant gas
leaks during the installation. Be careful not to allow
contact of the refrigerant gas with a flame as this will
cause the generation of poisonous gas.
•Keep all tubing runs as short as possible.
•Use the flare method for connecting tubing.
•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.
WARNING
•When performing piping work do not mix air
except for specified refrigerant (R410A) in
refrigeration cycle. It causes capacity down, and
risk of explosion and injury due to high tension
inside the refrigerant cycle.
•Check for a leaking refrigerant!
Refrigerant gas may produce a toxic gas if it
comes in contact with fire.
•Do not add or replace refrigerant other than
specified type. It may cause product damage,
burst and injury etc.
2
•Do not leak refrigerant while piping work for an
installation or re-installation, and while repairing
refrigeration parts.
Handle liquid refrigerant carefully as it may cause
frostbite.
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.
CAUTION
•Do not touch the air inlet or the sharp
aluminum fins of the outdoor unit. You
may get injured.
•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 after installation that no refrigerant gas
is leaking. If the gas comes in contact with a
burning stove, gas water heater, electric room
heater or other heat source, it can cause the
generation of poisonous gas.
WARNING
•This product must not be modified or
disassembled under any circumstances.
Modified or disassembled unit may cause fire,
electric shock or injury.
•Do not clean inside the indoor and outdoor units
by users. Engage authorized dealer or specialist
for cleaning.
•In case of malfunction of this appliance, do not
repair by yourself. Contact to the sales dealer or
service dealer for a repair.
Check of Density Limit
The room in which the air conditioner is to be
installed requires a design that in the event of
refrigerant gas leaking out, its density will not exceed
a set limit.
The refrigerant (R410A), which is used in the air
conditioner, is safe, without the toxicity or combustibility of
ammonia, and is not restricted by laws imposed to protect
the ozone layer. However, since it contains more than air,
it poses the risk of suffocation if its density should rise
excessively. Suffocation from leakage of refrigerant is
almost non-existent. With the recent increase in the
number of high density buildings, however, the installation
of multi air conditioner systems is on the increase
because of the need for effective use of floor space,
individual control, energy conservation by curtailing heat
and carrying power, etc.
Most importantly, the multi air conditioner system is able
to replenish a large amount of refrigerant compared to
conventional individual air conditioners. If a single unit of
the multi air conditioner system is to be installed in a
small room, select a suitable model and installation
procedure so that if the refrigerant accidentally leaks out,
its density does not reach the limit (and in the event of an
emergency, measures can be made before injury can
occur).
Others
CAUTION
•Do not sit or step on the unit, you may fall
down accidentally.
•Do not touch the air inlet or the sharp
aluminum fins of the outdoor unit. You may
get injured.
•Do not stick any object into the FAN
CASE.
You may be injured and the unit may be
damaged.
ASHRAE and the International Mechanical Code of the
ICC as well as CSA provide guidance and define
safeguards related to the use of refrigerants, all of which
define a Refrigerant Concentration Level (RCL) of
25 pounds (11.3 kg) per 1,000 cubic feet (28.3 m3) for
R410A refrigerant.
For additional guidance and precautions related to
refrigerant safety, please refer to the following documents:

2. SELECTING THE INSTALLATION SITE
2-1. Indoor Unit
AVOID:
● areas where leakage of flammable gas may be
expected.
● places where large amounts of oil mist exist.
● direct sunlight.
● locations near heat sources which may affect the
performance of the unit.
● locations where external air may enter the room
directly. This may cause “condensation” on the air
discharge ports, causing them to spray or drip water.
● locations where the remote controller will be splashed
with water or affected by dampness or humidity.
● installing the remote controller behind curtains or
furniture.
● locations where high-frequency emissions are
generated.
DO:
● select an appropriate position from which every corner
of the room can be uniformly cooled.
● select a location where the ceiling is strong enough to
support the weight of the unit.
● select a location where tubing and drain pipe have the
shortest run to the outdoor unit.
● allow room for operation and maintenance as well as
unrestricted air flow around the unit.
● install the unit within the maximum elevation difference
above or below the outdoor unit and within a total
tubing length (L) from the outdoor unit as detailed in
the installation manual packed with the outdoor unit.
● allow room for mounting the remote controller about
3.3 ft. (1 m) off the floor, in an area that is not in direct
sunlight or in the flow of cool air from the indoor unit.
● If the indoor unit is installed on the ceiling where the
temperature or humidity inside is high (over
86°F(30°C)/RH: 70%), add insulating material to the
surface of the unit to avoid dew condensation.

WARNING
It is important that you use extreme care in
supporting the indoor unit inside the ceiling. Ensure
that the ceiling is strong enough to support the
weight of the unit. Before hanging the unit, test the
strength of each attached suspension bolt.
(1) When placing the unit inside the ceiling, determine
the pitch of the suspension bolts referring to the
dimensional data as shown in Fig. 3-1 and Table 3-2.
Tubing must be laid and connected inside the ceiling
when suspending the unit. If the ceiling is already
constructed, lay the tubing into position for connection
to the unit before placing the unit inside the ceiling.
(2) Screw in the suspension bolts allowing them to
protrude from the ceiling (Fig. 3-3). (Cut the ceiling
material, if necessary.)
(3) Thread the 3 hexagonal nuts and 2 washers (field
supply) onto each of the 4 suspension bolts (Figs. 3-5
and 3-6). Use 1 nut and 1 washer for the upper part,
and 2 nuts and 1 washer for the lower part, so that
the unit will not fall off the suspension lugs.

3-3. Installing the Drain Pipe
(1) Prepare standard hard PVC pipe (O.D. 1-17/64" (O.D.
32 mm)) for the drain and use the supplied hose band
to prevent water leaks.
The PVC pipe must be purchased separately.
The transparent drain part on the unit allows you to
check drainage. (Fig. 3-8)
CAUTION
● Do not use adhesive tape at the drain connection
port on the indoor unit.
● Insert the drain pipe until it contacts the socket,
and then secure it tightly with the hose band.
● Do not use the supplied drain hose bent at a 90°
angle. (The maximum permissible bend is 45°.)
8
● Tighten the hose clamps so their locking nuts face
upward. (Fig. 3-8)
Align the wire of hose band without separating from the drain
hose and tighten so that it does not contact the bead.

● Do not install the pipe with an upward slant from the
connection port. This will cause the drain water to flow
backward and leak when the unit is not operating.
(Fig. 3-12)
Upward slant
Prohibited
Fig. 3-12
● Do not apply force to the piping on the unit side when
connecting the drain pipe. The pipe should not be
allowed to hang unsupported from its connection to the
unit. Fasten the pipe to a wall, frame, or other support
as close to the unit as possible. (Fig. 3-13)

Make sure the drain pipe has a downward slant (1/100 or
more) and that there are no water traps.
CAUTION
● Do not install an air bleeder as this may cause
water to spray from the drain pipe outlet. (Fig. 3-10)

● If it is necessary to increase the height of the drain
pipe, the section directly after the connection port
can be raised a maximum of 1.64 ft. (500 mm). Do
not raise it any higher than 1.64 ft. (500 mm), as
this could result in water leaks. (Fig. 3-11)
