Electric Fan Installation & Maintenance
Installation
The installation and troubleshooting of electric cooling fans
are to be carried out by a qualified electrician according
to the applicable local, state, province and federal codes.
Inspect for any damage that may have occurred during
transit. Check all bolts, screws, set screws, etc. Retighten

does not rub. Adjust if necessary. Before installation, read
the entire manual carefully.
This guide is pertinent only to electric fans furnished by the
Factory and manufactured by Multifan Inc. (can be verified
from nameplate on the electric fan). In the event the
electric fan furnished by the Factory is of a special nature
(manufactured by an alternate fan manufacturer), please
contact the Factory for appropriate electric fan installation
and maintenance instructions.
