Frame Sizes R7/R8 – NEMA 12 Enclosure Exhaust Filters
The exhaust filters in the R7/R8 NEMA 12 enclosure are located in the exhaust box at the top
of the enclosure.
There are 2 filter frames attached to the exhaust box.
1. Remove each filter frame:
• Lift up on the filter frame until it slides approximately ¾ inch.
• Pull away from the exhaust box to remove.
2. 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.
3. Remove and inspect the filter.
4. 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.
5. 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.
6. 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 ¾ inch).
• Check all around the filter frame for a secure seal to
the exhaust box.
