10.1 GENERAL INFORMATION

10.1.1 Specific features

(1) Less refrigerant charge amount due to use of double phase refrigerant flow system. The total refrigerant charge amount has been
reduced by more than 50%.
(2) The indoor outdoor interconnection signal wiring has been done away with. The microcomputer chip is installed in the indoor unit.
There is no need for the unit to communicate between the outdoor and indoor units so the unit is more resistant to electromagnetic
noise thus the incidence of microcomputer malfunction has been reduced. The compressor in the outdoor unit has its own self
protection function, that reacts according to abnormal high pressure and excessive high temperature.
(3) There are only four power lines between the outdoor and indoor unit. As no signal wire is used there is no need to separate the power
line from the signal line. One cab tyre cable with 6 wires encased in one sheath is enough for conducting the wiring work between
the outdoor unit and the indoor unit. This contributes to simpler wiring work in the field.
(4) All air supply ports have auto swing louvers. The indoor fan motor has two speeds of high and low.
(5) The controls are wireless residential split air conditioner type remote controller with 5 malfunction modes.
(6) All models have service valves protruding from the outdoor unit for faster flare connection work in the field.
(7) Simple design
With the model change, the design has been completely renewed. A simple and modern form with curves harmonizes more with the
interior. The suction grill also comes in two segments, simplifying the maintenance.
(8) Amazingly quiet operation
Due to adoption of a newly developed silent stream fan, unpleasant operation sound, such as sound made when the fan runs against
the air, has been minimized, thus achieving the trade's lowest noise level in the weak flow mode.
(9) "Aerowing" louver
In order to make air conditioning more comfortable, an "aerowing" louver has been newly developed by applying MHI's advanced
aerodynamics, leading to improved air directivity and air conditioning feeling. In the auto swing mode, the louver angle is optimum
from 0 (level) to 75°, thus distributing the refreshing air evenly throughout your room. By working the remote controller, you can
also set the louver angle easily. The sideways blowout angle can also be set manually up to 45° either right or left side.
