Components
Filters
The chimney vent hood comes supplied with
2 metal grease filters. (Also supplied is a single
charcoal filter for installations not vented to the
outside.) The metal filters trap grease released by
foods on the cooktop. The filters also help prevent
flames from damaging the inside of the hood. For
this reason the grease filters must always be in
place when the hood is in use.
The 2 vent hood grease filters are located on the
underside of the canopy. It is necessary to remove
the filters to gain access to the nomenclature, light
shield, duct cover, and the fan motor. To remove the
grease filters, pull out the visor, grasp the filter lock

will be recirculated through an additional single
disposable charcoal filter that helps remove smoke
and odors.
To remove the charcoal filter, first remove the 2
grease filters. Grasp the front of the charcoal filter
and pull it down and out.
To reinstall the charcoal filter, insert the back edge
into the rear (center). Push the front of the filter up
and snap it in place in the hood. Replace the 2 metal
filters.
