11. Attach the vent pipe extension with the 2” vent coupling, bringing the vent well above grade.
12. Clean all dirt and debris from top four corrugations on tank. Install the 24” coupler O-ring on the tank
between the top two corrugations with the white or yellow line facing out and on top.
13. Lube extension coupler and coupler O-ring with pipe lube or dish soap.
14. Manually press coupling evenly over lubricated O-ring. If additional force is needed, place a plywood
cover over the accessway and apply gentle mechanical pressure to the coupler.
Note: Care must be used
when pushing down on the coupler. Excessive force or impact may result in damage and leakage.
15. Frequent visual inspections during installation must be performed to determine when the tank has fully
engage the coupler.

18. Lube wet well vent grommet and vent pipe extension
with pipe lube, non-grit hand cleaner or dish soap and
slide vent pipe through grommet until tank shroud seats to
accessway.
19. Place SS band clamp around top corrugation and the
replacement shroud. Tap with a mallet around clamp to help
seat the clamp. Torque stud assembly on band clamp to a
maximum 125 inlb.
20. Reinstall the supply cable, EQD**, tank lid and
electrical shroud and tighten cable connector. (**See “EQD
wiring order,” Table 1)

- If the coupler will not
engage completely because the
discharge piping is in the way,
and it doesn’t have a cut out,
you will need to cut a slot in the
coupler.
- Using a hand, reciprocating
or hole saw, cut an arch in the
coupler; the cut-out is not to
exceed 5.50” tall or 5.00” wide.
