10. Filter Bag and Cage Installation
1.
From the clean-air plenum, carefully insert the snap band filter bag through the tubesheet with the closed end oriented
downward.
2.
Snap the bag in place with the tubesheet between the upper and lower rings on the filter bag collar shown in the Filter Bag
and Cage Installation illustration.
3.
Lower the filter cage into the bag. If the bag section is resting on the ground, the cages will not drop (seat) completely at this
time. When the dirty-air plenum is lifted into place, the cages will drop to the correct position (fully seat).
4. Repeat steps 1-3 for all bags.
Note: The cleaning arm will need to be manually rotated to access some bags.
5.
Once all bags are installed, ensure the cleaning arms rotate smoothly.
