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 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.

2 Features
2.1.Variety of excellent features
2.1.1.Compact design
• The height is only 288 mm and can be installed even where the space is limited.
2.1.2. Automatic restart function
• When the electric power comes back after a power failure, the unit itself automatically restarts the operation in the pre-failure mode.
2.1.3. 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.
2.1.4.Dry mode function
• Dry mode can make a comfortable indoor environment during wet season.
2.1.5. Quiet operation
• The sound level is as low as 37 dB (A) for model CS-F34DB4E5, 41 dB (A) for model CS-F43DB4E5 and suitable for offices, shops, homes etc., where quiet operation is essential.
2.1.6. Auto Swing Louvre
• The air flow angle can be changed automatically (or manually) to an angle between 10° to 70° using the remote control.
2.1.7.Low ambient cooling operation
• Cooling operation is possible at outdoor temperature of -5°C.

CS-F34DB4E5 CU-L34DBE5 / CS-F43DB4E5 CU-L43DBE5
2.2.Low-noise outdoor units
[Product features]
2.2.1.Low-noise design improves 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 reduces 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.

CS-F34DB4E5 CU-L34DBE5 / CS-F43DB4E5 CU-L43DBE5
2.3.Improved workability
2.3.1.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 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 for one size larger. Effective utilization of materials reduces working time and trouble. (Adaptor sockets are not supplied.)
2.3.2.Additional refrigerant charging
• All models do not require any additional charging of refrigerant for 30m of pipe length. This makes installation much easier.
2.3.3.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. Body connecting a drain elbow and a discharge pipe, water leakages can be prevented even when the unit is installed against a wall.
2.3.4. Space saving design allows units to be installed side by side continuously
• Servicing after installation can be carried-out by removing the front covers.
2.3.5.Easy test operation
• Test operation can be carried out for both indoor and outdoor units.
2.3.6.Long pipe design
• Maximum piping length of 50m.
2.3.7.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 9.53mm, making installation work much easier.

CS-F34DB4E5 CU-L34DBE5 / CS-F43DB4E5 CU-L43DBE5
2.3.8.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 improve appearance.
2.4.A brand-new control method
1.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.
2.Twin operation
•Simultaneous air conditioning of wide spaces and corners is possible. Indoor units of same horsepowers 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.
3.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.
4.Easy test operation
Test operation can be carried out for both indoor and outdoor units.
5.Automatic setting initialization function (Remote control and Indoor unit)
