gauge at the control panel.

5.3.5 Inspect the gasket on the new HEPA filter housing before installation, to make sure
there are no gaps, cracks, or defects. Any defects in the gasket will allow leakage of
contaminated air through the unit.

that the filter lies squarely on the base bracket.
5.3.7 Push the HEPA filter against the HEPA flange bulkhead and rotate the looking tabs

-THE NEW HEPA FILTER NEEDS TO BE THE SAME SIZE AND TYPE, AS THE ONE BEING
REPLACED.
- WHEN THE HEPA FILTER IS REPLACED, THE PRE-FILTER PAD AND RING PANEL FILTER
SHOULD ALSO BE REPLACED. THIS WILL HELP TO EXTEND THE LIFE OF THE HEPA FILTER
