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 filter media, the white side must face to outside of the cabinet,
and the colored 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.
