1 SERVICE INFORMATION
Caution:
O
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).
O
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.

2.1. 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 49 dB noise (W50BT - 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 speed 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.

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.
2.4. 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).
2.5. 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.
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.
2.7. 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.

2.9.1. Product features
•
• •
•
Low-noise design improves comfort 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
reducing 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.
2.10. Greatly improved workability
increases system renewal
capability
•
• •
•
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 and outdoor 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 or
one size larger. Effective utilization of materials reduces
working time and trouble. (Adaptor sockets are not
supplied.)
2.9. Low-noise outdoor units

refrigerant for 30 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.
•
• •
•
Save space design allows units to be installed side-byside continuously
−
− −
−
Servicing after installation can be carried out by
removing the front covers.
•
• •
•
Long pipe design for refrigerant pipes
−
− −
−

•
• •
•
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 9.52mm for 50BB models,
making installation work much easier.
•
• •
•
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 improves
appearance.
2.11. 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.
