Maintenance
4. For each filter frame, remove the
wire retainers that hold the filters
in place:
• Lay the filter frames on a flat
work surface.
• The wire retainers have a
square “U” shape. Remove by
squeezing the open end of the
“U” towards the middle of the
“square” until the retainer top (open end of “U”) clears the filter frame.
• Save the retainers for reinstallation.
5. Remove and inspect the filter.
6. Install clean filters.
Note: When installing DUSTLOK® filter media, the white side
must face to outside of the cabinet, and the orange side
faces in.
Be sure to tuck the filter edges into the groove around the
entire filter frame. This detail is very important for proper
operation.
7. Reinstall the filter restrainers.
• Insert the base of a retainer
(bottom of “U” shape) into a
filter frame channel.
• Squeeze the open end of the
“U” until it clears the filter
frame.
• Seat the open end of the “U”
in the filter frame channel.
• Release the retainer to its relaxed, square shape.
8. Install each filter frame to the bonnet on top
of the cabinet.
• Carefully align the frame’s mounting
hooks with the slots in the bonnet. (The
hooks should be pointing down.)
• Press down at the top of the filter frame.
(The filter frame slides down
approximately 3/4 inch).
• Check all around the filter frame for a
secure seal to the exhaust box.
