1 Service Information
The new Cassette / 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 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 capac-
ity 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 bal-
anced 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
• Long Pipe design with maximum piping length of 30m.
• Flexible 4-way piping.

• Centralized Drain Method gathered multiple outdoor unit’s drain pipes into a single drain pipe to makes installation easier and
also improve appearance.
• Side-by-Side Continuous Installation is possible even 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 -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. Wired Remote Control
1. The new design includes an easily-visible red pilot lamp. The power can be turned on and off at a single touch, without open-
ing the cover.
2. Has a build-in thermistor, allowing indoor temperature detection in accordance with indoor conditions by switching with main
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.

8.4. How to set remote control day and time
• The day and time needs to be set when you turn on the power for the first time or after a long time has elapsed since the power
was last turned on.
• The day and time becomes the standard time for all the Timer operations.
• Set the day and time accurately.
• Example : Current Day is Wednesday and Current Time is 8:00.
Note:
• Press “UP button” to increase or “DOWN button” to decrease (interval 1 minute) or hold the button to change the time faster.
• If the “UP or DOWN button” is not pressed for 30 seconds during the day or time setting or if the “SELECT button” is pressed, the
setting at that moment is confirmed and setting will end.
8.5. How To Select The Timer
• 2 types of Timer mode can be selected on the remote control.
- Daily Timer
- Weekly Timer
• These timers cannot be operated simultaneously.
• Select one of these Timers for your convenience.
How to Change the Display
• Press once to change the display from CLOCK to Timer or vice-versa.
• Press more than 3 seconds to change the display from Daily Timer to Weekly Timer or vice-versa.
