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.
8. Tighten the clamp bolts uniformly until the filter gasket is properly
compressed against the frame. Inspect the seal thoroughly before
proceeding.
9. Reinstall the filter access cover and the front panel.
10. Plug the enclosure in and have it recertified before use.

NE PAS être en contact avec la roué du ventilateur tant qu’il est

ATTENTION: The filter clamp bolts should only be tightened
enough to ensure a proper seal at maximum tightness. The
filter gasket should be compressed 50% or less.
