7. Clean-Air Outlet Plenum and Roof Installation
1. Place the clean-air outlet plenum panels onto the tubesheet. The tubesheet is used as a template to align the panels as in
previous sections. Do NOT apply sealant between the tubesheet and the plenum panels.
2.
Prior to setting an adjacent panel, apply sealant to all external vertical flanges within 1/8-in from flange edge as shown.
NOTE: The placement of the outlet is critical to ensure proper orientation. Consult the original order or Donaldson supplied
customer drawing to determine where to position the outlet.
Lifting lugs installed to the Clean- Air Outlet Plenum require Grade 8, 1/2-in diameter hardware (supplied with
collector). Using any other grade may result in lifting lug failure.
3.
Press vertical flanges together, align the holes, and insert the 1/2-in bolt hardware. Keep hardware hand tightened.
4. Repeat steps 2-3 for each panel until the entire clean-air outlet plenum ring is assembled.
5. Assemble roof onto clean-air outlet plenum.
6.
After applying sealant to the flanges of the roof panels and to the top flange of the clean-air outlet plenum, place one of the top
roof panels onto the top flange and bolt in place.
NOTE: Temporarily support the other end of the roof panel.
7.
Install the remaining roof panels applying sealant to all flanges.
8. Place top cap piece onto top panels making sure there is sealant in place before placing the cap piece.
NOTE: It is imperative that sufficient sealant be used to create an air tight seal.
9.
Tighten all bolts that have only been hand tightened up to this point. Reference the specification given previously in this
manual.
10. Remove assembly from tubesheet and set aside using standoffs to keep off grade.
