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.
2.3. 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.)

•
Additional refrigerant charging unnecessary for 30 m
−
− −
− All models do not require any additional charging of
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-by-
side continuously
−
− −
− Servicing after installation can be carried out by
removing the front covers.
•
• •
•
Long pipe design for refrigerant pipes
−
− −
− Maximum piping length of 50m for all models.
•
• •
•
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 34BB model,
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.
