Unit Start-Up (Continued)
15.Reattach the drive rod and swivel to the appropriate
hole(s). The length of the drive rod may need to be ad-
justed to align with the new hole(s) location. If so,
loosen the lock nut on the drive rod against the swivel.
Turn the swivel "in" or "out" to shorten or lengthen the
rod as necessary. For some holes, both ends of the rod
may need to be adjusted.
16.Tighten the lock nut against the swivel(s).
17.Plug the holes after the proper CFM has been estab-
lished.
