1. Features

Panel with LED display

1.1

1.2 Adopting DC fan motor

Efficiency can be up to 90%. Contrast with the AC fan motor, the power consumption of DC fan motor can

reduce up to 30%.

：

Air Flow：CFM

1.3 Convenient for installation

1.3.1 The ceiling type can be easily installed into a corner of the ceiling even if the ceiling is very narrow.

1.3.2 It is especially useful when installation of an air conditioner in the center of the ceiling is impossible due to a structure such as one lighting.

1.3.3 The EXV is built-in the indoor unit, compact size, and convenient for the installation.

1.3.4 Reserved the socket on main control board for water pump and PCB can be customized if you need water pump function.

1.4 Three air flow speed: high/middle/low, double air guides.

1.5 Two direction auto swing (vertical & horizontal) and wide

angle air flow

1.6 Low noise, creates quiet and comfortable environment.

1.6.1 Adoption of the Fujikoki brand electronic expansion valve, ensures precise flow control, as well as lower modulation noise when EXV operating.

1.6.2 Smoother airflow with less turbulence. Owing to the multiple-blade fan and the air guide design, the airflow is getting smoother and more comfortable
