1. Safety precautions
1.1. Before installation (Environment)
Caution:
• Do not use the unit in an unusual environment. If the air conditioner is installed
in areas exposed to steam, volatile oil (including machine oil), or sulfuric gas,
areas exposed to high salt content such as the seaside, the performance can
be signicantly reduced and the internal parts can be damaged.
• Do not install the unit where combustible gases may leak, be produced, ow,
or accumulate. If combustible gas accumulates around the unit, re or explo-
sion may result.
• Do not keep food, plants, caged pets, artwork, or precision instruments in the
direct airow of the indoor unit or too close to the unit, as these items can be
damaged by temperature changes or dripping water.
1.2. Before installation or relocation
Caution:
• Be extremely careful when transporting the units. Two or more persons
are needed to handle the unit, as it weighs 20 kg or more. Do not grasp the
packaging bands. Wear protective gloves as you can injure your hands on
the ns or other parts.
• Be sure to safely dispose of the packaging materials. Packaging materials,
such as nails and other metal or wooden parts may cause stabs or other
injuries.
• Thermal insulation of the refrigerant pipe is necessary to prevent condensation. If the refrigerant pipe is not properly insulated, condensation will be
formed.
• Place thermal insulation on the pipes to prevent condensation. If the drainpipe is installed incorrectly, water leakage and damage to the ceiling, oor,
furniture, or other possessions may result.
1.3. Before electric work
Caution:
• Be sure to install circuit breakers. If not installed, electric shock may result.
• For the power lines, use standard cables of sufcient capacity. Otherwise, a
short circuit, overheating, or re may result.
• When installing the power lines, do not apply tension to the cables.
• Be sure to ground the unit. If the unit is not properly grounded, electric shock
may result.
• When the room humidity exceeds 80% or when the drainpipe is clogged,
water may drip from the indoor unit. Do not install the indoor unit where such
dripping can cause damage.
• When installing the unit in a hospital or communications ofce, be prepared for
noise and electronic interference. Inverters, home appliances, high-frequency
medical equipment, and radio communications equipment can cause the air
conditioner to malfunction or breakdown. The air conditioner may also affect
medical equipment, disturbing medical care, and communications equipment,
harming the screen display quality.
• Do not clean the air conditioner unit with water. Electric shock may result.
• Tighten all are nuts to specication using a torque wrench. If tightened too
much, the are nut can break after an extended period.
• If the unit is run for long hours when the air above the ceiling is at high temperature/high humidity (dew point above 26 ºC), dew condensation may be
produced in the indoor unit or the ceiling materials. When operating the units
in this condition, add insulation material (10-20 mm) to the entire surface of
the unit and ceiling materials to avoid dew condensation.
• Use circuit breakers (ground fault interrupter, isolating switch (+B fuse), and
molded case circuit breaker) with the specied capacity. If the circuit breaker
capacity is larger than the specied capacity, breakdown or re may result.
1.4. Before starting the test run
Caution:
• Turn on the main power switch more than 12 hours before starting operation.
Starting operation just after turning on the power switch can severely damage
the internal parts.
• Before starting operation, check that all panels, guards and other protective
parts are correctly installed. Rotating, hot, or high voltage parts can cause
injuries.

3.5. Suspension structure (Give site of suspension
strong structure) (Fig. 3-5)
• The ceiling work differs according to the construction of the building. Building constructors and interior decorators should be consulted for details.
(1) Extent of ceiling removal: The ceiling must be kept completely horizontal and the
ceiling foundation (framework: wooden slats and slat holders) must be reinforced
in order to protect the ceiling from vibration.
(2) Cut and remove the ceiling foundation.
(3) Reinforce the ends of the ceiling foundation where it has been cut and add ceiling
foundation for securing the ends of the ceiling board.
(4) When installing the indoor unit on a slanted ceiling, attach a pillar between the
ceiling and the grille and set so that the unit is installed horizontally.
1 Wooden structures
• Use tie beams (single storied houses) or second oor beams (2 story houses) as
reinforcing members.
• Wooden beams for suspending air conditioners must be sturdy and their sides must
be at least 6 cm long if the beams are separated by not more than 90 cm and their
sides must be at least 9 cm long if the beams are separated by as much as 180
cm. The size of the suspension bolts should be ø10 (3/8"). (The bolts do not come
with the unit.)
2 Ferro-concrete structures
Secure the suspension bolts using the method shown, or use steel or wooden hangers, etc. to install the suspension bolts.
3.6. Unit suspension procedures (Fig. 3-6)
Suspend the main unit as shown in the diagram.
Figures given in parentheses represent the dimensions in case of installing optional
multi function casement.
1. In advance, set the parts onto the suspension bolts in the order of the washers
(with insulation), washers (without insulation) and nuts (double).
• Fit the washer with cushion so that the insulation faces downward.
• In case of using upper washers to suspend the main unit, the lower washers (with
insulation) and nuts (double) are to be set later.
2. Lift the unit to the proper height of the suspension bolts to insert the mounting
plate between washers and then fasten it securely.
3. When the main unit cannot be aligned against the mounting hole on the ceiling, it
is adjustable owing to a slot provided on the mounting plate.
• Make sure that A is performed within 17 - 22 mm. Damage could result by failing
to adhere to this range. (Fig. 3-7)
Caution:
Use the top half of the box as a protective cover to prevent dust or debris from
getting inside the unit prior to installation of the decorative cover or when applying ceiling materials.
3.7. Conrming the position of main unit and tightening
the suspension bolts (Fig. 3-8)
• Using the gauge attached to the grille, ensure that the bottom of the main unit is
properly aligned with the opening of the ceiling. Be sure to conrm this, otherwise
condensation may form and drip due to air leakage, etc.
• Conrm that the main unit is horizontally levelled, using a level or a vinyl tube lled
with water.
• After checking the position of the main unit, tighten the nuts of the suspension bolts
securely to fasten the main unit.
• The installation template (top of the package) can be used as a protective sheet
to prevent dust from entering the main unit when the grilles are left unattached for
a while or when the ceiling materials are to be lined after installation of the unit is
nished.
* As for the details of tting, refer to the instructions given on the Installation template.
• Use alkylbenzene oil (small amount) as the refrigeration oil applied to the
ared sections.
• Use C1220 copper phosphorus for copper and copper alloy seamless pipes,
to connect the refrigerant pipes. Use refrigerant pipes with the thicknesses
specied in the table below. Make sure the insides of the pipes are clean
and do not contain any harmful contaminants such as sulfuric compounds,
oxidants, debris, or dust.
Warning:
When installing or relocating, or servicing the air conditioner, use only the
specied refrigerant written on outdoor unit to charge the refrigerant lines. Do
not mix it with any other refrigerant and do not allow air to remain in the lines.
If air is mixed with the refrigerant, then it can be the cause of abnormal high
pressure in the refrigerant line, and may result in an explosion and other hazards.
The use of any refrigerant other than that specied for the system will cause
mechanical failure or system malfunction or unit breakdown. In the worst case,
this could lead to a serious impediment to securing product safety.

7. Test run
7.1. Before test run
► After completing installation and the wiring and piping of the indoor and
outdoor units, check for refrigerant leakage, looseness in the power supply
or control wiring, wrong polarity, and no disconnection of one phase in the
supply.
► Use a 500-volt megohmmeter to check that the resistance between the power
supply terminals and ground is at least 1.0 MΩ.
7.2. Test run
7.2.1. Using wired remote controller.
■ Make sure to read operation manual before test run. (Especially items to secure safety)
Step 1 Turn on the power.
● Remote controller: The system will go into startup mode, and the remote controller power lamp (green) and “PLEASE WAIT” will blink. While the lamp and message are
blinking, the remote controller cannot be operated. Wait until “PLEASE WAIT” is not displayed before operating the remote controller. After the power is turned on, “PLEASE
WAIT” will be displayed for approximately 3 minutes.
● Indoor controller board: LED 1 will be lit up, LED 2 will be lit up (if the address is 0) or off (if the address is not 0), and LED 3 will blink.
● Outdoor controller board: LED 1 (green) and LED 2 (red) will be lit up. (After the startup mode of the system nishes, LED 2 will be turned off.) If the outdoor controller
board uses a digital display, [- ] and [ -] will be displayed alternately every second.
If the operations do not function correctly after the procedures in step 2 and thereafter are performed, the following causes should be considered and eliminated if they
are found.
(The symptoms below occur during the test run mode. “Startup” in the table means the LED display written above.)
Symptoms in test run mode
Remote Controller Display
Remote controller displays “PLEASE WAIT”, and
cannot be operated.
After power is turned on, “PLEASE WAIT” is displayed for 3 minutes, then error code is displayed.
No display appears even when remote controller
operation switch is turned on. (Operation lamp
does not light up.)

Step 4 Conrm the operation of the outdoor unit fan.
The speed of the outdoor unit fan is controlled in order to control the performance of the unit. Depending on the ambient air, the fan will rotate at a slow speed and will keep
rotating at that speed unless the performance is insufcient. Therefore, the outdoor wind may cause the fan to stop rotating or to rotate in the opposite direction, but this is
not a problem.
Step 5 Stop the test run.
