1. Safety precautions
Please read these "Safety precautions" carefully before installing air
conditioning equipment and be sure to install it correctly.
After completing installation, conduct a trial operation to check for
faults and explain to the customer how to operate the air
conditioner and take care of it with the aid of the operation manual.
Ask the customer to store the installation manual along with the
operation manual for future reference.
This air conditioner comes under the term "appliances not
accessible to the general public".
Meaning of WARNING and CAUTION notices.
WARNING Failure to follow these instructions properly
may result in personal injury or loss of life.
CAUTION Failure to observe these instructions properly
may result in property damage or personal
injury, which may be serious depending on
the circumstances.
WARNING
• Ask your dealer or qualied personnel to carry out installation
work.
Do not attempt to install the air conditioner yourself. Improper
installation may result in water leakage, electric shocks or re.
• Perform installation work in accordance with the instructions in
this installation manual. Do not modify the product.
Improper installation may result in water leakage, electric shocks,
or re.
• Be sure to use only the specied accessories and parts for
installation work.
Failure to use the specied parts may result in the unit falling,
water leakage, electric shocks or re.
• Make sure that specied wires are used and that there is no
strain on the terminal connections or wires.
Improper connections or securing of wires may result in
abnormal heat radiation or re.
• Be sure to switch off the unit before touching any electrical parts.
• Arrange the lead wires of the provided harness so that the EL.
COMPO. BOX lid of the indoor unit will not rise, and attach the lid
securely.
Heat radiation, electric shocks, or re may result if the EL.
COMPO. BOX lid is not attached properly.
• Tear up and dispose of the plastic bag.
Children playing with the plastic bag may be suffocated.
CAUTION
• Install the indoor and outdoor units, power cord, remote controller
wiring, and transmission wiring at least 1 m away from TV or
radio sets. This is for the prevention of TV and radio interference.
(Depending on the incoming signal strength, a distance of
1 meter may not be sufcient to eliminate noise.)
• Pay the utmost attention to the transportation of the product.
Hold the handles on the package to carry the product.
Do not carry the package with the polypropylene band on the
package held, which will be dangerous because the
polypropylene band may be deformed.
• Do not touch the n of the heat exchanger.
Touching the n improperly may result in injury.
• Do not turn the product power off immediately after the operation
of the product comes to a stop.
Always wait for at least 5 minutes before turning the product
power off.
Otherwise, water leakage and malfunctions may result.
• Do not install the air conditioner in the following locations:
1. Where there is a high concentration of mineral oil spray or
vapour (e.g. a kitchen).
Plastic parts will deteriorate, parts may fall off and water
leakage could result.
2. Where corrosive gas, such as sulphurous acid gas, is
produced.
Corroding of copper pipes or soldered parts may result in
refrigerant leakage.
3. Near machinery emitting electromagnetic radiation.
Electromagnetic radiation may disturb the operation of the
control system and result in a malfunction of the unit.
4. Where ammable gas may leak, where there is carbon bre or
ignitable dust suspensions in the air, or where volatile
ammables such as paint thinner or gasoline are handled.
Operating the unit in such conditions may result in re.
[Instructions peculiar to this product]
Do not install the product in the following places.
Oil, cigarette tar, and steam will result in sticky dust on the lter,
which may not be cleaned properly. Furthermore, sticky dust may
cause malfunctions.
Places with oily smoke: Restaurants, factories, etc.
Places with excessive cigarette smoke: Smoking room, etc.
Places with excessive moisture or steam: Restaurants, factories,
etc.
• The air conditioner is not intended for use in a potentially
explosive atmosphere.
Note
• Have the customer actually operate the air conditioner while
referring to the operation manual and explain the right operation
of the air conditioner with useful tips given.
• Refer to the operation manual along with the installation manual
provided with the indoor unit.
• Use the BRC1E51A7 remote controller.
2. Accessory
Check that the following accessories provided with the air
conditioner are correct in number. See the following illustration,
which shows where the accessories are kept.

* Be sure to recheck the items provided in the section "1. Safety
precautions" on page 1.
b. Test items before delivery
Test items Result
Was the test operation of the air conditioner nished?
Did you explain the operation method of the air
conditioner to the customer while showing the customer
the operation manual? *
Did you make mode settings for lter auto cleaning
(automatic control operation settings or timer operation
settings with an operation time zone specied) and

(Be sure to hand the customer the operation manual as
well as the installation manual.)
Did you hand the customer the connecting pipe and
attachment and ask the customer to keep them?
* Point of operation explanation
In addition to the general usage of the air conditioner, it is
necessary to explain the descriptions of the WARNING and
CAUTION marked items in the operation manual and have
the customer read the descriptions carefully, because these
items indicate information that, if not heeded, is likely to result in
loss of life, serious injury, or property damage.

6-1 Checks before attaching panel
• Check the directions of the indoor unit and the engraved marks
on the panel as shown below.
The piping block to the PIPING SIDE and the drain socket to
the DRAIN SIDE .
• Stand the temporary latching bracket upright.
• Draw out the lead wires (on the panel side) from the opening.
6-2 Attaching panel
(1) Tentatively put the two temporary latching brackets of the
suction port of the panel (on the internal circumference side) to
the hooks of the indoor unit.
Note
Leave your hands after conrming through the check window
that the temporary latching brackets are engaged with the
hooks.
(2) Draw out from the opening the harness attached in "5.
Preparations for indoor unit" on page 4.
Furthermore, pull out the lead wires disconnected from the
corner decoration cover (with the display) in "4. Preparations
for panel" on page 3 from the corner hole carefully so that
the lead wires will not be caught by the mounting bracket.
(3) Put the mounting brackets (in four points) on the corners of the
panel to the hooks of the circumference of the indoor unit.
(Hook the mounting bracket engraved with the PIPING SIDE
rst, followed by the mounting bracket on the opposite angle
side.)
At that time, pay attention that the harness and lead wires (on
the panel side) will not be caught between the panel and
indoor unit.
Note
Leave your hands after conrming that the mounting brackets
are engaged with the hooks.
(4) Tighten the four hexagon head screws right under the
mounting bracket for approximately 5 mm. (The panel will
move upward.)
(5) Turn the panel in the directions of the arrows so that the
opening on the ceiling will be perfectly covered by the panel.
(6) Furthermore, tighten the screw (4) until the distance from the
lower part of the hook of the indoor unit to the lower part of the
panel becomes 107 to 112 mm.
