With using external input function, some functions on this product can be controlled from an external device.
• “Operation/Stop” mode or "Forced stop" mode can be selected with function setting of indoor
unit.
• A twisted pair cable (22AWG) should be used. Maximum length of cable is 492 ft (150 m).
• The wire connection should be separate from the power cable line.

The air conditioner can be remotely operated by means of the following on-site work.
Operation is started at the following contents by adding the contact input of a commercial on/off
switch to a connector on the external control PCB and turning it on.
Unit operation Initial setting after power is on
Operation mode Auto changeover Mode at previous operation
Set temperature 76 °F (24 °C) Temperature at previous operation
Airflow mode AUTO Mode at previous operation
Air direction (swing) Standard air direction (swing: off) Air direction at previous operation

NOTE: The information listed below are general precautions.
Some models also include items that do not apply.
• Places where there is a danger of combustible gas leakage.
• Places where sulfur gas, chlorine gas, acid, alkali, or other matter which effects equipment is
generated.
• Places where there is a lot of oil splash and steam such as kitchen or machinery room.
• Places where machinery which generates high frequencies is used.
• Ocean beaches and other areas where there is a lot of salt.
• Places where carbon fibers or any kind of powder suspended in the air.
• Inside of vehicles, ships, and other conveyances.
• Places where voltage fluctuations are large such as a factory.

• The product shall be installed at a place which can withstand the weight and vibration of the
indoor.
• To allow maintenance after refrigerant piping, drain piping, and electric wiring connection and
installation, provide an installation service space and an inspection port, as required.
*Installation service space is shown on "Dimensions" on page 8.
• Be careful when installing the unit at the following places.
Condition Contents Countermeasures (Reference)
When the
ceiling is high.
When lower
level directly
contacts the
outside air.
When the air
flow distribution
is poor.
When inside
the ceiling is
high
temperature
and high
humidity.
If the indoor unit is installed where the installation height
given in the installation manual is exceeded, the
temperature difference between the floor and ceiling of
the room will be large and the heating effect will be poor.
Moreover, even if the indoor unit is installed within the
installation height, a similar phenomena will occur when
installed in a room in which the doors are opened and
closed frequently and hot air circulation is obstructed by
furniture such as desks or chairs.
When the lower level of the room is a semi-open space
such as warehouse or parking lot the surface
temperature of the flooring will become low and the
radiation of cold from the floor will increase.
In this case, even if the room temperature is suitable,
you may feel the foot level is cold.
When an indoor unit is installed in a position where the
outlet airflow will directly contact people, a draft may be
felt.
In addition, when there are obstructions in the path of the
intake and outlet airflow, the air distribution may become
extremely bad.
When the indoor unit is installed where the inside of the
ceiling is 30 °C (86 °F) RH80% or greater, the dew point
temperature of the outer perimeter may become higher
than the cabinet surface temperature and moisture will
condense on the surface of the cabinet and water drops
may fall inside the room. →Refer to Fig. A.
In addition, the humidity may vary considerably the same
as when the inside of the ceiling is close to hermetically
sealed and used as the outside air intake path.
1. Switch the setting to the high
ceiling mode.
2. Install a circulator.
3. Arrange the furniture in the
room so that it does not
obstruct the hot air.
1. Adjust the louver fins or take
other measures matched to the
site.
2. Change the indoor unit outlet.
1. Add heat insulating material to
the outside of the indoor unit
cabinet.
*Regarding the cassette type,
use of optional High humidity
correspondence kit is
recommended.
2. Strengthen the heat insulating
material of the refrigerant
piping and drain piping too.
→Refer to Fig. B.
3. When the humidity inside the
ceiling changes considerably,
install a ventilation port.

Condition Contents Countermeasures (Reference)
If the cold or warm air blown out from the air conditioner
directly contacts the thermostat section of the remote
controller, the outlet temperature of the air conditioner
may be sensed and room temperature control will be
different from the room temperature, and “not cooled” or
“not heated” or other trouble may occur.
In addition, there is the possibility that the same kind of
1. Install the remote controller
where it will not be directly
exposed to the cold or hot air.
2. Install the remote controller
where it will not be directly
exposed to sunlight or strong
lighting.
trouble may also occur when the remote controller is
effected by direct sunlight.
When the wall mounted type was installed in a bedroom,
living room, or other quiet place, the sound of the
refrigerant flow may be sensed as noise and must be
taken into account.
1. Plan installation of a model
with external expansion valve.
2. Plan installation of a branch
box farther from indoor unit.
3. Plan installation using another
air conditioner.
Signals may not be received when using it in a room
illuminated by an inverter fluorescent lamp.
Turn on the fluorescent lamp and
check if the indoor unit receives the
signals from the remote controller.
If the indoor unit does not receive
the signals, consult an authorized
service personnel.
It may generate noise in TV sets, stereos and PCs. The inverter type should be
installed at a sufficient distance
from these equipments.

NOTES:
• If the space is larger than stated above, the condition will be the same as when there is no
obstacle.
• Height above the floor level should be 2 in (50 mm) or more.
• When installing the outdoor unit, be sure to open the front and left side to obtain better operation efficiency.
CAUTION
• Do not install the outdoor unit in two-stage where the drain water could freeze. Otherwise the
drainage from the upper unit may form ice and cause a malfunction of the lower unit.
• When the outdoor temperature is 32 °F (0 °C) or less, do not use the accessory drain pipe
and drain cap. If the drain pipe and drain cap are used, the drain water in the pipe may
freeze in extremely cold climate. (For reverse cycle model only.)
• In area with heavy snowfall, if the inlet and outlet of the outdoor unit is blocked with snow, it
might become difficult to get warm, and it is likely to cause product malfunction. Construct a
canopy and a pedestal, or place the unit on a high stand that is locally installed.
