Note:

1. We will not guarantee the products if your application exceeds the limitations outlined in this specification.

2. Please do not touch and push fan blade with fingers or others. Fan blade and ball bearings may be damaged. And it caused noise defect.

3. Please avoid operating SFENGDA's products in poisonous material(organic, cyanogens, formalin, phenol, etc.)or corrosive gas environment(H₂S, SO₂, NO₂,etc.)

4. We do not warrant performance safety against accidents caused by dust, water, droplets dew, bugs, etc.

5. Always ensure that fans are stored according to the storage temperatures specified. Do not store in a high humidity environment. If the fans are stored for more than 6 months, we recommend functional testing before using.

6. Please do not damage this product this product including coil and lead wires while installing or wiring. There may be smoking or fire.

7. Avoid the damage, check the correct voltage and proper polarity before connecting with power.

8. Improper mounting may cause harsh resonance, vibration, and noise. Please mount securely.

9. It is very important to notify that avoid to drop from 60cm height when in any movement or operation, it will impact the balance of blade. Especially ball bearing structure is avoided to drop down.

10. Safety is a top priority. Please furnish guard accessories to prevent injury to personnel
