1 Service Information

The new Cassette / New Outdoor models are possible to have address setting for twin control or group 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.) Howeve r, 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 group 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 memorize 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.

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

1.4. Operation range

1.4.1. Power Supply

The applicable voltage range for each unit is given in the following table. The working voltage among the three phases must be bal­anced within a 3% deviation from each voltage at the compressor terminals. The starting voltage must be higher than 85% of the
rated voltage.

2.1. Ceiling Type

2.1.1. Easier Maintenance and Cleaning

• Anti-Mould Long Life Air Filter.

• 3-Direction Pipe Lead-Out.

2.1.2. Wide Air Discharge, Comfortable Control

• Wide-Angle Airflow — 100 Degrees Horizontal.

• Auto Swing Louver.

2.2. Outdoor Unit

2.2.1. Flexible Installation in Smaller Spaces

• Spacing-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.

6

• Long Pipe design with maximum piping length of 40m (50Hz), 50m (60Hz).

• Flexible 4-way piping.

• Centralized Drain Method gathered multiple outdoor unit’s drain pipes into a single drain pipe to make installation easier an d
also improve appearance.

• Side-by-Side Continuous Installation is possible eve n 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 shaped suppressed
the generation of vortexes, thus reduces air flows noise.

• Operating efficiency is improved and energy consumption reduced.

2.2.3. Low Ambient Cooling Operation

• The unit can set for cooling even when the outdoor temperature drops to 5°C. This is ideal for locations that require cooling even
in winter.

7

2.3. Wired Remote Control

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

2. Has a build-in thermistor, allowing indoor temperature detection in accordance with indoor conditions by switching with mai n
unit thermistor.

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

2.4. Wireless Remote Control

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

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

NOTE: Both of the above remote control is packed separately from the indoor unit.
