1. Features
1.1 New panel and optimized evaporator
---- For capacity 1.8kW to 3.6 kW, the panel has digital display function, which can show
temperature ,warning message and check to consult parameters.
---- For capacity 4.5kW to 5.6kW, has a optimized evaporator.
1.2 Compact design
---- For capacity 1.8kW to 3.6 kW,needs only 153 mm space above the ceiling.
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) guarantees comfort in
large space.
1.5 Improved air quality
---- For capacity 1.8kW to 3.6 kW, 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.
1.8kW-3.6kW
4.5kW-5.6kW

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
--- For capacity 1.8kW to 3.6 kW, 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.
