1 SERVICE INFORMATION

Notice of Address setting for NEW Cassette / NEW Outdoor Unit.

The new Cassette / new Outdoor models are possible to have address setting for twin / triple control or group control
automatically when main power supply is switched on.

(Manual address setting is also possible by using DSW1 switch on the indoor unit P.C. board.) However, this address setting is
only possible when proper wiring connection is made and indoor unit must be of original unit.

1.1. Example of trouble during test operation

If the below phenomenon is found during test operation, wrong address setting is possible.
Therefore, please inspect the address setting.

1. LCD display of the wired remote control is not illuminated although the main power supply switch is ‘on’.

2. LCD display had indicated as normal illumination when power supply switch is ‘on’, however outdoor unit cannot be operated.
(But, it is necessary to take 3 to 5 minutes for outdoor unit to start from the timing of remote control OFF/ON button is ‘on’.)
(For normal operation, the outdoor unit will only start its operation after 3 to 5 minutes upon pressing the OFF/ON button.)

3. P.C. board had memorized wrong setting information.
a. If main power supply is switched on with the wrong connection.
b. When changing the connection or combination of units due to re-installation etc.

• • When changing the system from twin to triple (triple to twin).

• • When changing the system from group control to normal one to one system.

• • When making the replacement of units of master and slave etc.

1.2. Caution during test operation

Do not touch the remote control button and do not change any wirings for one minute when the main power supply switch is ‘on’.
(Because the unit is having automatic address setting during the first one minute.)

1.3. Caution during automatic address setting

When the main power supply switch is ‘on’, the P.C. board will automatically memorize the connecting system.
Consequently, when initial power supply is ‘on’, there mustn’t be any interchanging of units even of the same type and same

capacity unit.
Therefore, connection of the unit to another system is prohibited.

2 FEATURES

2.1. Variety of excellent features

• • Compact design

Compact design 240 mm height, 840 mm width and 840
mm depth. (3 HP unit body)

• • Automatic restart function

When the electric power resumes after a power failure, the
unit will automatically restarts the operation in the pre­failure mode.

• • Auto fan mode (indoor unit)

Auto fan mode is added besides HI, ME and LO.
It automatically adjusts the fan speed according to the
indoor temperature.

• • Dry mode function

Dry mode can make a comfortable indoor environment
during wet season.

• • Quiet operation

The sound level is 41dB (A) for 28BB model during High

Fan speed and suitable for offices, shops, homes etc, when
quiet operation is essential.

• • Auto Swing Louvre

The air flow angle can be changed automatically (or
manually) to an angle between 10° to 70° using the remote
control.

• • Low ambient cooling operation

Cooling operation is possible at outdoor temperature of

-5°C.

• • Automatic changeover function (heat pump models)

The unit automatically switches between cooling and
heating in accordance with operating load in order to
maintain a comfortable indoor temperature.

• • Hot start system (heat pump models)

• • Pipes and drainage

Built-in upward draining mechanism.

2.2. Low-noise outdoor units

CASSETTE TYPE

2.2.1. Product features

• • Low-noise design improves comfort in surrounding
areas

1. The noise-suppressing winglet fan is a result of new

research into vane design theory. The unique curved
shape suppresses the generation of vortexes, thus
reducing air flow noise.

2. The adoption of double-orifice rings reduces air

passage resistance.

3. Strengthening of the noise insulation materials in the

compressor and the sealing-in of mechanical noise
allows vibration noise to be greatly enclosed and
suppressed.

4. The heat exchanger has an L-shaped design to allow air

to flow more smoothly.

5. Noise is automatically reduced further during night-time

operation with lower outdoor air temperatures.

2.3. Greatly improved workability
increases system renewal
capability

• • Pipes that are one size larger can also be connected for

renewal.

− − If renewing the system, existing refrigerant pipes can be
utilized so that only the indoor and outdoor units need to
be replaced.

− − For example, liquid and gas pipes from 10 years ago
can be connected to current pipes with the same size or
one size larger. Effective utilization of materials reduces
working time and trouble. (Adaptor sockets are not
supplied.)

5

• • Additional refrigerant charging unnecessary for 30 m

− − All models do not require any additional charging of

refrigerant for 30 m of pipe length. This makes
installation much easier.

• • Drain water dripping-prevention structure

− − The base of the outdoor unit is provided with a single

drain hole in order to prevent drain water from leaking
out of the unit. By connecting a drain elbow and a
discharge pipe, water leakages can be prevented even
when the unit is installed to a wall.

• • Save space design allows units to be installed side-by-

side continuously

− − Servicing after installation can be carried out by
removing the front covers.

• • Long pipe design for refrigerant pipes

− − Maximum piping length of 50m for all models.

• • Internal pipe connection

− − Pipes are connected inside the units (inside the side

covers), making the final appearance more attractive.

− − Pipes can be diverted outward in any of four directions
(forward, right, down, rear).

− − Small liquid pipe diameters of 9.52mm for 43BB and
50BB models, making installation work much easier.

• • Centralized draining method

− − Even when multiple outdoor units are installed to a wall,

the drain outlets can be concentrated into a single drain
pipe. This makes installation easier and also improves
appearance.

2.4. A brand-new control method
using the latest in technology

• • Easier power supply wiring connection

Power supply wiring and other wiring tasks can be carried
out more easily.

− − Twin non-polar wires used to connect indoor and
outdoor units.

− − Adoption of connection error prevention circuits for drive
wires and signal wires. If a connection error is made, the
relay does not operate and current does not flow to the
circuit boards.

• • Twin and Triple operation

− − Simultaneous air conditioning of wide spaces and

corners is possible. Indoor units of different
horsepowers can even be used in combination.

− − Master unit and slave-units can be set automatically in
twin and triple systems. No address setting is
necessary.

− − Multiple indoor units can be operated simultaneously
with a single remote control. Note that individual
operation is not possible.

• • Separate indoor/outdoor unit power supplies

The power supply can be connected to (1) just the outdoor
units, or (2) to both the indoor and outdoor units.

• • Easy test operation

Test operation can be carried out for both indoor and
outdoor units.

• • Automatic setting initialization function (Remote control
and Indoor unit)
In accordance with the indoor and outdoor units connected
and the connection methods, conditions such as the
connection configuration (twin or triple format) and remote­control functions such as automatic louvre operation and
cooling or heating mode are automatically detected and set
instantly.

CASSETTE TYPE

2.5. Wired Remote Control

• • The new design includes an easily-visible red pilot lamp.
The power can be turned on and off at a single touch,
without opening the cover.

• • Has a built-in thermistor, allowing indoor temperature
detection in accordance with indoor conditions by switching
with main unit thermistor.

• • Twin non-polar wires make installation work easy. (10 m
cable supplied as accessory.)

2.6. Wireless Remote Control

• • New design with compact size. (Operation range within
approximately 8 m.)

• • Built-in timer with ON/OFF timer setting (within 24 hours)
