Beginning with the back row, gently lift the filter cartridge and position the
hooked end of the support rod in the hole in the spider assembly welded
in the opening of the tube sheet. The short, right-angle bend in the
support rod will keep the support rod from turning completely around
when it is positioned in the spider assembly.
5.
With the spider assembly centering the filter cartridge in line with the tube
sheet hole, guide the cartridge up against the spider assembly by
tightening the filter cartridge-retaining nut on the end of the support rod.
6.
While ensuring that the filter cartridge is aligned with the hole in the
tubesheet, tighten the filter cartridge-retaining nut enough to compress
the seal and test by making sure the filter cartridge can no longer be
rotated by hand.
7.
Repeat this procedure for the entire back row of filter cartridges.
8.
Make one last inspection of all filter cartridges in the completed row for
proper alignment and tightness before proceeding to the next row.
9.
Proceed to the next row and repeat the procedure for the entire row of
filter cartridges.
10.
Again, make one last inspection of all filter cartridges in the completed row
of filter cartridges.
11.
Install the inlet baffles on the front of the AirWall unit by lifting and
hanging the baffle assemblies. Make sure the support lip on the top of the
baffle assembly interlocks with the lip on the top of the air inlet opening.
12.
Install the dust collection drawers in the base of the AirWall unit.
