Changing the HEPA Filter:
1. Turn the unit “OFF” and disconnect the power cord from the electrical outlet.
2. Remove the screws that hold the HEPA filter access panel in place and set the panel aside.
3. Remove the wing nuts that secure the HEPA filter retaining bracket in place, slide the bracket off the
long filter retaining bolts and remove the HEPA filter.
4. Carefully place a new HEPA filter (P/N: H610C-99) into the cabinet, making sure that it rests on the
curved section of the cabinet base, which is just behind the long, lower filter retaining bolt. The foam
seal of the filter should be aligned with the exhaust outlet.
5. Place the HEPA filter retaining bracket over the retaining bolts and secure it in place with the wing nuts.
Do not over-tighten the wing nuts.
6. Re-attach the HEPA filter access panel and secure it to the cabinet with its screws.
Warning:
Use only Abatement Technologies pre-filters, HEPA filters, and replacement parts. Substitute parts
void the warranty, jeopardize worker and environmental safety, and adversely affect engineered
performance levels.
