Before installation
1. Before installing the negative pressure fan, it is necessary to carefully check whether the negative pressure fan is intact, whether the bolts of each fastener are loose or detached, and whether the impeller collides with the fan cover. Carefully inspect the fan blades or louvers for any deformation or damage during transportation.
2. When selecting the air outlet environment for installation, it should be noted that there should be no large obstacles within 2, 5-3 meters opposite the air outlet.
During installation

2. When installing the negative pressure fan, the adjustment bolts of the motor should be in a convenient position for operation. To facilitate the adjustment of belt tension during use.
3. When installing the negative pressure fan bracket, ensure that the bracket is level and stable with the foundation plane, and install angle iron next to the negative pressure fan for further fixation.
4. After the installation of the negative pressure fan, the sealing around it should be checked. If there are gaps, they can be sealed with a sunboard or glass glue.
After installation
1. After installation, check if there are any tools and debris left inside the negative pressure fan. Use your hand or lever to move the fan blades and check for any tightness or rubbing. If there are any items that hinder rotation and no abnormalities, then proceed with the trial run.
2. If there is vibration of the negative pressure fan or abnormal noise or other abnormal phenomena in the motor during operation, the machine should be shut down for inspection. It should be repaired before starting up for use.
