1、 Installation steps for pipeline ventilation fan

1. Build wooden frames and install them onto ceiling joists. Seal the main body and install it inside the wooden frame, and firmly fix it with self tapping screws (4 pieces).

2. Install the pipeline into the air outlet and lock it with a rubber band.

3. Seal the main body and install it inside the frame.

4. After turning on the power, check if the following abnormal phenomena have occurred.

5. Insert the fixed spring into the groove and install the panel onto the sealed body.

2、 Precautions for installation of pipeline ventilation fans

The external dimensions of the pipeline ventilation fan should comply with the building module coordination standard.

A dedicated socket or switch with grounding should be installed near the pipeline ventilation fan, and the switch position should consider easy operation; Linkage switches, delay switches, or human body induction switches can be selected as needed.

The ceiling duct ventilation fan should be installed on a stable ceiling and firmly connected to the ceiling. If possible, rubber pads can also be used to reduce the noise caused by vibration. When installing the ceiling, the indoor net height should not be less than 2.2m.

The pipeline of the ventilation fan cannot be bent within 0.5 meters from the interface; There should be no more than two large bends less than 90 degrees throughout the entire process; It is not advisable to reduce the diameter of the pipeline in the middle, otherwise it will affect the air volume, air pressure, and motor life; During the bending process, the angle should not be less than 120 degrees, otherwise it will affect the air volume, air pressure, and motor life.
