1. Features
1.1 New panel design
The new panel is equipped with digital display function, which can show temperature, warning message and
check running parameters.
1.2 Compact design
For capacity 1.8kW to 3.6kW,needs only 153mm space above the ceiling. And 189mm for 4.5~7.1kW
models.
1.3 Parts inside installation
The throttling components and water pump are internally installed which means lower cost, no extra
accessories or installation time.
1.4 Large airflow and low noise
Large airflow, for high ceiling application (installation height can reach up to 3.2m for 1.8~3.6kW models and
4.0m for 4.5~7.1kW models) guarantees comfort in large space.
1.5 Improved air quality
Two folding type air filters and two standard formaldehyde absorption nets improve the air quality greatly.
The design of a long air outlet and a wide guide fan blade, which enlarges the range of flow transportation.
1.6 Auto swing
Auto swing mechanism guarantees even airflow distribution and a better room temperature balance.
1.7 Built-in water pump with 750mm pump head
1.8 Prevent condensation in air outlet by the patent of a new structure design
By the adoption of this structure, the guide wing will always wrapped up by dry cold air, cutting off the contact
route of moist hot air and the cold guide wing.As a result, the water vapour in mosit hot air gets no change to
condense in the surface of guide wing.
1.9 Auto restart
When the indoor unit is powered off, it will auto restart when powered on again after 3 minutes and operate
in the previous state.
