the plenum, if present.

To Install a Supply HEPA Filter:
1.
Install a new supply HEPA filter by pushing it straight into the cabinet,
ensuring that it is correctly oriented, and that the filter is centered on the
filter shelf.
2.
Use the 7/16- and 1/2-inch sockets or wrenches to sequentially loosen the
three plenum lift bolts located as noted in Figure 6-27. When properly
positioned, the plenum box will be aligned with the supply HEPA filter frame.
Continue to loosen the bolts until the plenum contacts the HEPA filter and
has slightly compressed the filter gasket.
NOTE: The lift bolts should only be tightened enough to ensure a proper seal
of the supply HEPA filter. At maximum tightness, the supply filter's gasket
should be compressed to less than 50% of its original thickness. NEVER
tighten the locking bolts beyond this setting.
