See Notice on first page
Notes:
1. Lift the air filter, using the plastic tabs, into the cavity at the bottom of the OC-12 shelf at an angle as shown.
2. Place the rear edge of the filter on top of the shelf “lip” and push forward to compress the leaf springs
attached to the shelf.
3. While applying enough pressure to keep the leaf springs compressed, rotate the front of the filter upward
until it contacts the bottom of the shelf cavity.
4. Release the filter and ensure that the leaf springs force the filter forward to the position shown, securing it
within the shelf cavity.
