Maintenance
Replacing Filters
The filters will need changing when the red filter condition
indicator is glowing.
A log of the changes should be maintained by the user.
The filters require attention when the LED illuminates RED
or when the extractor no longer removes fume efficiently.
It is recommended that a spare set of filters are kept on site
to avoid prolonged unit unavailability. Part numbers for
replacement filters can be found on the filters fitted in your
system.

blocked filter condition, or with dust obstruction of Inlets /
Outlets.
