Commissioning, Startup, Operation, and Shutdown
• Flush and clean the system thoroughly to remove dirt or debris in the pipe system in order
to prevent premature failure at initial startup.
• Bring variable-speed drivers to the rated speed as quickly as possible.
At initial startup, do not adjust the variable-speed drivers or check for speed governor or over-
speed trip settings while the variable-speed driver is coupled to the pump. If the settings have
not been verified, then uncouple the unit and refer to instructions supplied by the driver
manufacturer.
Remove the coupling guard
1. Remove the nut, bolt, and washers from the slotted hole in the center of the coupling guard.
2. Slide the driver half of the coupling guard toward the pump.
3. Remove the nut, bolt, and washers from the driver half of the coupling guard.
4. Remove the driver-side end plate.
5. Remove the driver half of the coupling guard:
a) Slightly spread the bottom apart.
b) Lift upwards.
6. Remove the remaining nut, bolt, and washers from the pump half of the coupling guard.
It is not necessary to remove the end plate from the pump side of the bearing housing. You
can access the bearing-housing tap bolts without removing this end plate if maintenance of
internal pump parts is necessary.
7. Remove the pump half of the coupling guard:
a) Slightly spread the bottom apart.
b) Lift upwards.

Check the rotation - Frame Mounted
WARNING:
• Operating the pump in reverse rotation can result in the contact of metal parts, heat generation, and
breach of containment.
•
Always disconnect and lock out power to the driver before you perform any installation or
maintenance tasks. Failure to disconnect and lock out driver power will result in serious physical
injury.
• Electrical connections must be made by certified electricians in compliance with all international,
national, state, and local rules.
• Refer to driver/coupling/gear manufacturers installation and operation manuals (IOM) for specific
instructions and recommendations.
1. Lock out power to the driver.
2. Make sure that the coupling hubs are fastened securely to the shafts.
3. Make sure that the coupling spacer is removed.
The pump ships with the coupling spacer removed.
4. Unlock power to the driver.
5. Make sure that everyone is clear, and then jog the driver long enough to determine that the
direction of rotation corresponds to the arrow on the bearing housing or .
6. Lock out power to the driver.
