Exhaust Filter for UL Type 12

For UL Type 12 there is also a filter in the exhaust box at the top of the cabinet.
Exhaust filters should be inspected every 6 months and replace as needed
depending on accumulated dust and the environment. Exhaust filters should be
changed at a minimum every year as part of standard preventative maintenance.
The UL Type 12 exhaust filter may be accessed and replaced by the following
procedure.
1. There are 2 filter frames attached to the filter / fan box on top of the UL Type 12
cabinet. To remove the filter frames, lift up on the filter frame until it slides
approximately ¾ inch. Then remove the filter frame. Repeat this process for the
other side.
2. Lay the filter frames on a flat work surface. Remove the retaining bracket by
squeezing the tabbed corners in towards the middle of the bracket until the bracket
clears the filter frame. Save these brackets for replacement. Remove and inspect
the filter. Repeat this process for the other side.
