a) Slightly spread the bottom apart.
b) Lift upwards.
5.3 Check the rotation
WARNING:
• Starting the pump in reverse rotation can result in the contact of metal parts, heat genera-
tion, and breach of containment. Ensure correct driver settings prior to starting any pump.
• Failure to disconnect and lock out driver power may result in serious physical injury or
death. Always disconnect and lock out power to the driver before performing any installa-
tion or maintenance tasks.
• Electrical connections must be made by certified electricians in compliance with all
international, national, state, and local rules.
• Refer to driver/coupling/gear manufacturer's 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 direc-
tion of rotation corresponds to the arrow on the bearing housing or close-coupled frame.
6. Lock out power to the driver.
5.4 Couple the pump and driver
WARNING:
• Failure to disconnect and lock out driver power may result in serious physical injury or
death. Always disconnect and lock out power to the driver before performing any installa-
tion or maintenance tasks.
• Electrical connections must be made by certified electricians in compliance with all
international, national, state, and local rules.
• Refer to driver/coupling/gear manufacturer's installation and operation manuals
(IOM) for specific instructions and recommendations.
1. Check the gap between the coupling hubs against the dimensions shown on the general arrange-
ment drawing or as stamped on the coupling hub. For any necessary adjustment, move the driver
not the pump.
Motors with sleeve bearings may be manufactured with 6.35 or 12.7 mm | 1/4 or 1/2 in. end move-
ment (float) in the motor rotor. For limited end-float arrangement, the gap between the coupling
halves must be set in a different manner. If specific directions are not indicated in the motor instruc-
tions, then follow this procedure:
NOTICE:
If the driver was mounted at the factory, the setting for the coupling is already determined.
