the site safety officer.
To replace the filter, remove the front cover of the remote filter housing and pull
the filters out. Slide the replacement filters in so that the 'direction of flow' arrow
printed on the carton duplicates that shown on the diagram overleaf and replace
the front cover.
As dust contained in the dust separators may expose maintenance personnel to
a nuisance dust hazard as defined by the Control of Substances Hazardous to
Health (COSHH), it is strongly recommended that suitable masks and protective
clothing be worn when changing filters. Used separators are not intended for re-
use and should be safely disposed of.
After fitting new Dust Separator cartridges, a FastLearn must be initiated.
