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.
1. Lock out power to the driver.

3. Make sure that the coupling spacer is removed.
The pump ships with the coupling spacer removed.
4. Unlock power to the driver.

direction of rotation corresponds to the arrow on the bearing housing or close-coupled
frame.

Precautions
WARNING:
• Follow shaft alignment procedures in order to prevent catastrophic failure of drive components or
unintended contact of rotating parts. Follow the coupling installation and operation procedures from
the coupling manufacturer.
• Never operate the pump without the coupling guard correctly installed.
• Avoid death or serious injury. Assure mechanical seal guard is properly installed using supplied
fastening hardware.
• 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.
• The coupling used in an Ex-classified environment must be properly certified and must be
constructed from a non-sparking material.
