Loosen each of the eight 3/8” hex head bolts on the front seal panel. Be sure not to damage or lose
the seal washers on each bolt.

Remove the front seal panel making sure that you do not damage the gasket. The filters are now
exposed.
7.
Loosen the ½ - 13-plenum clamp bolts, located on each side of the downflow plenum, approximately
3 ½ revolutions or until the supply plenum is raised about ¼” above the filter.

Loosen the filter gasket seal from the metal plenum. A putty knife works fine to break the gasket seal
if necessary. Align the downflow filter with the notches in the frame of the plenum and remove the
filter by sliding it towards you.
NOTE: once removed, the filters should immediately be sealed in a chemical hazard bag
appropriately marked for the type of hazard and then disposed of safely in accordance with
environmental regulations. If you are not removing the exhaust filter, proceed to step number 11.
If only the exhaust filter is to be changed, the downflow plenum clamp bolts (lower) should be
loosened four or more revolutions before loosening the exhaust plenum clamp bolts (upper).

Alternately loosen the ½ - 13-plenum clamp bolt, located on each side of the exhaust plenum,
approximately 3 ½ revolutions or until the exhaust plenum is lowered about ¼”.
See Figure 3
