Replacing the Fan Assembly

To replace the fan assembly, remove the switch’s cover and the existing fan
assembly, then install a new fan assembly and replace the switch’s cover.

NOTE:

You do not need to power off the switch to replace the fan assembly. The switch

can safely run for up to 25 minutes under average conditions while the fan assembly is
being replaced.
