ELECTING
When the conditions in the ceiling are exceeding 30°C and a relative
humidity of 80%, or when fresh air is inducted into the ceiling, an
additional insulation is required (minimum 10 mm thickness,
polyethylene foam).
For this unit you can select different air flow directions. It is necessary
to purchase an optional blocking pad kit to discharge the air in 2 or 3
directions.
1 Select an installation site where the following conditions
are fulfilled and that meets your customer's approval.
• Where optimum air distribution can be ensured.
• Where nothing blocks air passage.
• Where condensate water can be properly drained.
• Where the false ceiling is not noticeably on an incline.
• Where sufficient clearance for maintenance and service can be
• Where piping between indoor and outdoor units is possible within
•Keep indoor unit, outdoor unit, power supply wiring and
2 Ceiling height
This indoor unit may be installed on ceilings up to 3.5 m in height
(for 80~125 units: 4.2 m). However, it becomes necessary to
make field settings by the remote controller when installing the
unit at a height over 2.7 m (for 80~125 units: 3.2 m). To avoid
accidental touching, it is recommended to install the unit higher
than 2.5 m.
Refer to the chapter "Field setting" and to the decoration panel
installation manual.
3 Air flow directions
Select the air flow directions best suited to the room and point of
installation. (For air discharge in 2 or 3 directions, it is necessary

piping and the liquid piping. Otherwise, this can sometimes result in
water leakage.
Before rigging tubes, check which type of refrigerant is used.
INDOOR UNIT INSTALLATION
When installing optional accessories (except for the decoration
panel), read also the installation manual of the optional accessories.
Depending on the field conditions, it may be easier to install optional
accessories before the indoor unit is installed. However, for existing
ceilings, install fresh air inlet component kit and branch duct before
installing the unit.
1. Install the indoor unit temporarily.
• Attach the hanger bracket to the suspension bolt. Be sure to fix it
securely by using a nut and washer from the upper and lower
sides of the hanger bracket.

2 Connect the drain hose to the drain outlet on the indoor unit, and
tighten it with the clamp.
Precautions
■ Install the drain raising pipes at a height of less than 550 mm.
■ Install the drain raising pipes at a right angle to the indoor unit
and no more than 300 mm from the unit.
NOTE
■ The incline of attached drain hose should be
75 mm or less so that the drain socket does not
have to stand additional force.
■ To ensure a downward slope of 1:100, install
hanging bars every 1 to 1.5 m.
■ If unifying multiple drain pipes, install the pipes as
shown in figure 9. Select converging drain pipes
whose gauge is suitable for the operating capacity
of the unit.
■ If the refrigerant gas leaks during the work, ventilate the area. A
toxic gas is emitted by the refrigerant gas being exposed to a fire.
■ Finally make sure there is no refrigerant gas leak. A toxic gas

2 Keep total current of crossover wiring between indoor units less
than 12 A. Branch the line outside the terminal board of the unit
in accordance with electrical equipment standards, when using
two power wiring of a gauge greater than 2 mm
2
(Ø1.6).
The branch must be sheathed in order to provide an equal or
greater degree of insulation as power supply wiring itself.
3 Do not connect wires of different gauge to the same grounding
terminal. Looseness in the connection may deteriorate the
protection.
4 Remote controller cords and wires connecting the units should
be located at least 50 mm away from power supply wiring. Not
following this guideline may result in malfunction due to electrical
noise.
5 For the remote controller wiring, refer to the "Installation manual
of the remote controller" supplied with the remote controller.
6 Never connect the power supply wiring to the terminal board for
transmission wiring. This mistake could damage the entire
system.
Precautions
1. A single switch can be used to supply power to units on the same
system. However, branch switches and branch circuit breakers must
be selected carefully.
2. For a group control remote controller, choose the remote
controller that suits the indoor unit which has the most functions.
3. Do not ground the equipment on gas pipes, water pipes,
lightning rods or crossground with telephones. Improper
grounding could result in electric shock.
FIELD SETTING
Field setting must be made from the remote controller in accordance
with the installation condition.
■ Setting can be made by changing the "Mode number", "FIRST
CODE No." and "SECOND CODE No.".
■ For setting and operation, refer to the "Field setting" in the
installation manual of the remote controller.
7 Use only specified wires and tightly connect wires to the
terminals. Be careful that wires do not place external stress on
the terminals. Keep wiring in neat order so that they do not
obstruct other equipment such as popping open the service
cover. Make sure the cover closes tight. Incomplete connections
could result in overheating, and in the worse case, electric shock
or fire.
