2. Features
2.1 Cassette type
2.1.1 Fresh Air
Fresh air intake function bring you fresh and comfortable air feeling.
2.1.2 Wired Controller (Optional)
Compared with infrared remote controller, wired controller can be fixed on the wall and avoid mislaying.
It's mainly used for commercial zone and makes air conditioner control more convenient.
2.1.3 Build-in Drain Pump
The drain pump can lift the condensing water up to 750mm(compact cassette)/1000mm(new cassette)
upmost.
It’s convenient to install drainage piping under most space condition.
2.1.4Terminals For Alarm Lamp and Long-distance On-off Controller Connection Are Standard
Remote on-off: With the reserved ports. a remote switch can be easily connected to realize remote
control.
Alarm: The built-in PCB can output alarm signal, which achieve setting up an external alarm light or
vibration gauge

2.2A6 Duct
2.2.1 Constant air volume control
For ordinary duct, when the static pressure exceeds the expected range, it is fairly difficult even for an
experienced installer to calculate and adjust the air volume precisely.
With constant air volume control technology, the duct will automatically adjusts to perfect static pressure
and keep constant air volume.
2.2.2 Flexible Air Intake Way (Bottom side or Rear side)
The frame size of air inlet in rear and bottom is the same. It’s very easy to switch to match different
application.
2.2.3 Communication wire connection
A6 duct uses two wires without polarity connection way, which almost has no mistake during the
installation.
2.2.4 Easy Clean
With a larger window design, once the motor and the blower wheels have been detached, heat
exchanger and water receiver tray in behind can be seen very clearly. Dust can be easily removed from
the inside by vacuum
Air intake from rear (Standard)
Air intake from bottom (Optional)

2.2.5 Fresh air intake function(Optional)
Install one duct from the reserved fresh-air intake to outdoor.
Continually inhale the fresh air to improve the quality of the indoor air, fulfills air quality more healthy and
comfortable.
A ventilation motor (provided by the installer) can be installed inside the fresh air duct to improve the
fresh air volume. There are reserved ports for this motor on main PCB (Standard for 3D inverter units,
and only optional for DC inverter 53~160 units).
2.2.6 Built-in drain pump (Optional)
Built-in drain pump can lift the water to 750mm upmost, which widens the drainage piping range.

2.3.1 An Elegant And Compact Design
•The look of newly-upgraded console unit features flowing lines that is aesthetic enough.
•Its unobtrusive design can easily fit into most interiors with different decorating-schemes.
•The width of the machine has been reduced by 10mm, taking less space.
2.3.2 A Perfect Choice For New Buildings And Renovation Projects
•Console unit can be installed standing on the floor, or wall-mounted
•It is a great option for radiator replacement in order to save your space while provide more functions.
1.3 Dual Air Outlets With Larger Dimension
Efficiently improve air volume, providing constant, quick cooling and heating throughout whole year.
Wide Airflow & Constant Comfort-Dual air outlets satisfy both cooling and heating needs in different seasons
and allows a quick comfort of the room.

1.4 Air Quality
We care your indoor air quality from many perspectives
•Get Ideal HUMIDITY for You
•New console efficiently dehumidify the air to keep the ambient air dry and at comfort humidity level.
•Display screen on front panel is reliable and user-friendly to operate to use.
•Ion-Generator for a Space with Better Air Quality
•A built-in positive & negative ion generator in Airwell console produces powerful ions that binds to and
neutralises airborne pollutants for a cleaner environment.
•Ions attach to airborne particles, which are then later collected onto an oppositely-charged flat plate.
