- Before installation, the manhole cover foundation must be neat and sturdy, and the inner diameter as well as length and width should be determined according to the dimensions of the manhole cover.
- When installing composite manhole covers on cement surfaces, ensure that the masonry around the well opening is properly filled with concrete, and also construct a concrete protective ring around the perimeter. Allow the installation to cure for about 10 days before use.
- When installing composite manhole covers on asphalt surfaces, care should be taken to avoid direct碾压 (rolling) of the covers and frames by construction machinery, as this could lead to damage.

To ensure the proper functioning of composite manhole covers, it's important to pay attention to the quality of installation—making sure not only that the dimensions are accurate, but also that the cover is easy to open and maintains a clean, aesthetically pleasing appearance.
