1 SERVICE INFORMATION
Caution:
●Pb free solder has a higher melting point than standard solder; Typically the melting point is 50 - 70°F (30 - 40°C) higher. Please use a high temperature soldering iron. In case of the soldering iron with temperature control, please set it to 700 ± 20°F (370 ± 10°C).
● Pb free solder will tend to splash when heated too high (about 1100° F/600°C).
Notice of Address setting for NEW Ceiling / NEW Outdoor Unit.
The new Ceiling / 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.New design
2.1.1.Gentle curved styling
•The base has gentle curves which express a functional beauty. It spreads the air quietly over a wide area.
2.2.Such quietness!
2.2.1.Several new mechanism add up to low 36 dB noise (A18BT - High Fan Speed)
1.Delta throat fan
A delta throat (projection) has been attached to the fan outlet to suppress the generation of vortexes. This helps maintain air flow sped even at lower fan speeds and is effective in reducing noise.
2.Reflux orifice
The orifice at the intake port is equipped with an air flow guide which minimizes the flow disturbances which occur at the orifice and inside the impeller.
This reduces pressure losses inside the casing and also helps reduce noise.
3. Adoption of wing-shaped vanes
•The vanes of the fan have been changed to “aerodynamic” shaped vanes, so that the air flow more smoothly over the vane surfaces and noise is thus suppressed.
•Side filters have been adopted in the pipe partitions. These allow the air intake space to be increased and also further reduce noise.
2.2.2.Automatic swinging louvre
•The horizontal air flow angle is a wide 100 degrees (manual). The louvre can swing automatically (through 70 degrees vertically) using the remote control. This increases the area of comfortable air flow and warms the air even to floor level.
2.2.3.Newly-shaped louvre
•The newly-shaped louvre and air outlet effectively distribute the air flow. During cooling, this stops warm air from collecting near the louvre, and prevents freezing.
4
2.3.Easy installation
2.3.1.Easy suspension
•A suspension bolt fixing bracket with 4-point support is attached to the main unit, which increases the space available for installation.
2.3.2.Two installation methods : standard and wall
•In addition to the standard (1) ceiling installation, a wall (2) installation method (using a wall-hanging bracket) is available for cases where the ceiling is too high for the main unit to be suspended.
2.5.2.Maintenance is possible from underneath the unit.
•If the bottom panel is detached, the drain pan can then be removed and installed from underneath the unit, and inspection and servicing of component such as the control panel also becomes easier.
2.6.Auto fan mode (indoor unit)
•Auto fan mode is added besides high, medium and low. It automatically adjusts the fan speed according to the indoor unit’s temperature.
2.4.Piping
2.4.1.3-direction pipe lead-out
•The refrigerant piping can lead out in one of three directions (right, rear-right and top-right), and the drain pipe direction can be selected from four directions (right, rear-right, left and rear-left).
2.7.Hot start system (heat pump models)
2.8.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.
2.9.Greatly improved workability increases system renewal capability
•Pipes that are one size larger can also be connected for renewal.
−
2.5.Easy maintenance
2.5.1.Long life filter (standard equipment)
•In general office environments, cleaning (maintenance) is not required until after approximately 2,500 hours of operation, thus reducing maintenance work.
•For optimum comfort, it is recommended to clean the air filter every 1-1/2 months.
−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 10 m
−All models do not require any additional charging of refrigerant for 10 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.
•Long pipe design for refrigerant pipes
−Maximum piping length of 25m for all models.
2.10.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.
2.11. 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 build-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.)
6
2.12. Wireless Remote Control
2.13. Group Control Equipment
•New design with compact size. (Operation range within approximately 8 m.)
•Built-in timer with ON/OFF timer setting (within 24 hours)

10 PIPE LENGTH
■ CORRECTION OF COOLING CAPACITY AND HEATING CAPACITIES
Correction of cooling and heating capacities according to the connecting pipe length.
The data of cooling capacities (marked on the name plate) are based on 5 meters connecting pipe and horizontal installation. For other pipe length of other installation multiply by the following correction factor to determine the revised cooling capacity.
■REFRIGERANT ADDITIONAL CHARGE
1.Piping installation by standard piping
•At the time of shipment from the factory, this unit is charged with enough refrigerant for an equivalent pipe length of 10m. (Refer to the following table)
But when the piping length exceeds 10m, additional charge is required according to the following table.
Example: CU-C18BBP5
In case of 11m long pipe (one way), the amount of refrigerant to be replenished is: (11 - 10) x 20 = 20g

2.Piping installation by existing piping
The above models change the liquid pipe size of the previous series. It is to use the existing piping by adjusting the refrigerant gas volume.
Please do correct piping installation referring to the above table.
Attention
•Please do not decrease the gas piping size. (It causes the breakdown of the compressor).
•The equivalent piping length and the cooling and heating capacity change rate are same as the standard piping specification.
