Note:
Before installing the ventilation assembly, please remove the steel mesh, otherwise, the air supply volume will be affected.
1. Adding shutters decreases air supply, as well as cooling/heating capacity and energy efficiency. This effect is increased as
shutter angle increases. Installing additional shutters is not recommended. If additional shutters are necessary, shutter angle
should not be greater than 15 degrees.
2. The bending place at ventilated duct should be not more than 1(show in above figure), in order to avoid operation malfunction..
3. Install the flexible connector between the unit and the air deflector pipe to avoid vibration noise.
