1 SERVICE INFORMATION
Notice of Address setting for NEW Duct / NEW Outdoor Unit.
The new Duct Type / New Outdoor models are possible to have address setting for twin control by automatic when main
power supply is switched on.
(Manual address setting is also possible by using Dip switch on Indoor unit P.C. board.) However, this address setting is only
possible when made proper wiring connection and also Indoor unit should be original virgin unit.
1.1. Example of trouble at test operation
If found out as following phenomenon at test operation on site, it may have possibility of wrong address setting.
Therefore, please ensure of the address setting.
1.LCD display of wired remote control had not illuminate 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 ON/OFF switch is ‘on’.)
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 control to normal one to one system.
• When making the replacement of units as master and slave etc.
1.2. Caution of test operation
Do not touch the remote control switch 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 main power supply switch is ‘on’, the P.C. board will automatically memorized the connecting system.
Consequently, when initial power supply is ‘on’, there will not be interchangeability of units even of the same type and same
capacity unit. Therefore unable to connect the unit to another system.
1.4. Operation range
The applicable voltage range for each unit is given in “the following table”. The working voltage among the three phases must be
balanced within 3% deviation from each voltage at the compressor terminals. The starting voltage must be higher than 85% of the
rated voltage.

2.1. Hide-away type
2.1.1. Thin, lightweight design
• The unit has a low height, so it allows installation in limited
ceiling spaces. The lightweight, attractive design simplifies
installation, and matches virtually all room interiors.
2.1.2. Flexible installation
• The powerful airflow enables a longer duct to be used.
Since the air outlet can be installed away from the main
unit, a variety of air conditioner layouts become possible.
2.1.3. Easy maintenance
• Maintenance works can be done from the underside of the
indoor unit.
2.2. Outdoor unit
2.2.1. Flexible installation in smaller
spaces
• Space-saving outdoor unit with the improvement of the
outdoor unit fan makes it possible to install the outdoor unit
into a smaller space where the conventional model cannot
be installed.
• Long pipe design with a maximum piping length of 50m.
• Additional charging of refrigerant are not required for 30m
of pipe length.
• Flexible 4-way piping.
• Centralized drain method gather multiple outdoor units’
drain pipes into a single drain pipe to make installation
easier and also improve appearance.
• Side-by-side continuous installation is possible even for
outdoor units with different capacities.
2.2.2. Quiet, efficient design
• A host of silencing technologies achieves super-quiet
operation.
• 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 reduces air
flows noise.
• Operating efficiency is improved and energy consumption is
reduced.
2.2.3. Low ambient cooling operation
• The unit can set for cooling even when the outdoor
temperature drops to -10°C. This is ideal for location such
as non-residential computer room (where the temperature
is not less than 21°C and humidity is not more than 45%)
that require cooling even in winter.

2.3.1. Twin operation
• Simultaneous air conditioning of wide spaces and corners is
possible. Indoor units of same horsepowers and models
can even be used in combination.
• Master unit and slave-units can be set automatically in twin
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.
