WARNING:
Lifting and handling heavy equipment poses a crush hazard. Use caution during lifting and
handling and wear appropriate Personal Protective Equipment (PPE, such as steel-toed shoes,
gloves, etc.) at all times. Seek assistance if necessary.

The back pull out assembly consists of all parts except the casing (100) and casing insert (100W-
venturi casings only). The casing (100) can remain on the foundation and in the piping, if it is not
the casing itself, which must be repaired. Drain the casing, by removing the casing drain plug (if
equipped).Remove the case nuts (425) and washers (533).
2.
Tighten the jackscrews (418) evenly, using an alternating pattern, in order to remove the back pull-
out assembly.
You can use penetrating oil if the adapter to the casing joint is corroded.
