to shafts.
s
! WARNING
Do NOT jog a coupled pump.
NOTE: Pump is shipped with coupling spacer
removed.
3. Unlock driver power.
4. Make sure everyone is clear. Jog driver just long enough to
determine direction of rotation. Rotation must correspond
to arrow on bearing frame.
5. Lock out power to driver.
COUPLING PUMP AND DRIVER
s
! WARNING
Lock out driver power to prevent accidental rotation
and physical injury.
!
The coupling used in an ATEX classified environ-
ment must be properly certified.
1. Install and lubricate coupling per manufacturer’s
instructions.
!
The coupling guard used in an ATEX classified
environment must be constructed from a non-
sparking material.
2. Install coupling guard. Refer to coupling guard
installation instructions in Appendix I.
