ArcShield Plenum Installation Instructions Appendix E
STEP 3 – Sequence of Final
Assembly
All Plenums in a Line-up must be mounted to the top of each enclosure and to
the Plenum directly beside it before the front duct sections are re-attached (see
Figure 87
).
Figure 92 - Sequence of Final Assembly
The “End Cover Plate” must be mounted on the closed end of the Line-up at this
time during the assembly using 5/16-inch hardware (see Figure 92
Left side).
STEP 4 – Closing the Front of
the Plenum Sections
After the first stage of the Plenum assemblies have been mounted, the Plenums
can then be “closed-up” by replacing the front duct sections as shown in Figure 93
to Figure 95
.

IMPORTANT
Do not re-install the front duct section of the last Plenum on the exhaust side
of the Line-up at this time (refer to STEP 6 – Mounting Extension/Elbow to
Plenum “Line-up” on page 193 for more information).
TIP
Use silicone caulking generously to fill any air gaps once the Plenum has been
securely mounted in place.
