silicone grease, if desired.
7. Install the new HEPA filter by pushing it straight into the cabinet, ensuring
that it is correctly oriented with the gasket facing up on the exhaust side of
the enclosure. The filter gasket is surrounded by a negative pressure
plenum and the gasket will not leak. Be sure the filter fits properly.

compressed against the frame. Inspect the seal thoroughly before
proceeding.

filter gasket should be compressed 50% or less.
