For bag and cage installation in top access type filter bags, as
shown in above figure, lower the bottom of the bag through
the hole in the tube sheet. Next, fold the snap band (bag top)
into a kidney shape to insert it into the tube sheet hole.
Positioning the seam first, fit the groove of the snap band to
the edge of the tube sheet and allow the band to snap into
place. You should hear a sharp popping noise when the band
is properly seated around the circumference of the tube
sheet hole. Check the fit of the snap band. It should fit
securely all around with no wrinkles in the snap band. To
complete installation, slide the cage into the bag until it rests
on the tube sheet. Be careful when installing the filter bag.
Do not let your fingers fall between the snap band and the
tube sheet hole when snapping the bag.
If the bags are equipped with a grounding strip, fold the wire
over the top of the bag and down its side prior to fitting in
the tube sheet. The wire should be between the bag cuff and
the tube sheet.
