Step 5 – Plenum/Blower Removal
The Plenum/Blower and Upper Frame can be lifted off the top of the enclosure together,
if at least four (4) persons or a mechanical lift are available. If those resources are
available, this step may be skipped.
Reference Figure 4-19. Remove the three (3) Filter Tabs by removing the single screw
on each. Using a 1/2" socket and ratchet, turn the four (4) Plenum Lift Bolts
COUNTERCLOCKWISE until the Plenum/Blower Assembly lowers and then is free from
each Lift Bolt. Do not attempt to turn each bolt the entire distance, rather work in a
pattern turning each bolt no more than 10 revolutions, then move to the next. This will
lower the Plenum/Blower evenly.
Placing two (2) boards (one at the right end and one at the left end) underneath the
Plenum, such that they sit on the Upper Frame on both ends of the board, before the
Plenum is completely released will aid in the removal (and re-installation) of the
Plenum/Blower Assembly.
