Before installation, carefully inspect the fan for any damage or deformation caused during transport; if any is found, repairs must be completed before proceeding with installation. During installation, check all connections for looseness and ensure the clearance between the blades and the fan casing is uniform, with no contact or scraping.
The weight of the ductwork connected to the fan outlet must not be borne by the fan casing; separate supports must be provided during installation. An inlet cone (or bell-mouth) must be installed at the fan inlet, and the installation of a protective wire mesh is recommended. The fan base must mate naturally with the foundation surface; do not force a connection by striking the base. During installation, align the base, use shims to ensure it remains level, and then tighten the anchor bolts.
After installation is complete, a test run must be performed; the fan may only be put into regular operation once it is confirmed to be running normally.
