On explosion proof models, the diamond shaft is retained in the PULSAmatic unit and
does not come out so the drive shaft assembly must be fed into the housing cap as
the cover assembly is lowered onto the pump. The slotted nut (#535) should be
adjusted as above. Access to this nut is provided through small subcover (#529A).

properly.
Refer to the “Installation” section for more detailed set-up and wiring information.
