9 Fan maintenance – Open the access panel, remove HEPA filter if fitted and,
by looking through fan inlet eye, inspect fan thoroughly. If necessary, remove
all residual dust accumulation. (Although the fan is located on the clean side
of the collector, it is possible for low quantities of dust to migrate through the
filter media).
The fan should be inspected immediately after any period of
significant dust emission, i.e. due to damaged filter media or seal
etc.
The fan should be inspected immediately if there is any unexpected
noise, temperature or vibration.
The fan should be inspected every twelve months or immediately
following any misuse.
If inspection reveals any damage then the fan must not be put back
into service until properly repaired or replaced.
