1. Carefully read the user manual and product samples of the centrifugal fan, familiarize and understand the specifications, form, impeller rotation direction, and airflow inlet and outlet direction of the fan; Recheck whether all components of the centrifugal fan are intact, otherwise they should be repaired before installation and use.

2. Centrifugal fans must be installed with safety devices to prevent accidents, and must be installed and wired by professionals familiar with relevant safety requirements.

3. The air ducts connecting the inlet and outlet of the fan are separately supported, and it is not allowed to add overlapping weight of the ducts to the components of the fan; When installing a centrifugal fan, attention should be paid to the horizontal position of the fan. The connection between the centrifugal fan and the foundation and the air outlet duct should be adjusted to ensure a natural fit, and forced connection is not allowed.

4. After the installation of the centrifugal fan, use your hand or lever to move the impeller and check for any tightness or rubbing, as well as any objects that hinder rotation. Only when there are no abnormal phenomena can the test run be carried out. The exposed part of the fan transmission device should have a protective cover (provided by the user). If the fan inlet is not connected to the pipeline, a protective net or other installation device (provided by the user) should also be added.

5. The distribution control box of the centrifugal fan must be matched with the corresponding fan (referring to power, voltage, pneumatic mode, control form, etc.).

6. The wiring of centrifugal fans should be done by professional electricians, and the wiring must be correct and reliable, especially the wiring number at the electrical control box should correspond to the number on the fan terminal. The fan housing should be reliably grounded, and grounding must be reliable. Zero grounding cannot be used instead of grounding.

7. After the installation of all centrifugal fans, it is necessary to check whether there are any remaining tool boxes or debris inside the fan.
