Preparation for startup
DANGER:
Electrical hazard sufficient to kill. Always disconnect and lock out the power before you
service the unit.
WARNING:
• Failure to follow these precautions before you start the unit will lead to serious personal
injury and equipment failure.
• Do not operate the pump below the minimum rated flows or with the suction or
discharge valves closed. These conditions can create an explosive hazard due to
vaporization of pumped fluid and can quickly lead to pump failure and physical injury.
• Never operate the pump without the coupling guard correctly installed.
• 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.
• Operating the pump in reverse rotation can result in the contact of metal parts, heat
generation, and breach of containment.
NOTICE:
• Verify the driver settings before you start any pump.
You must follow these precautions before you start the pump:
• Flush and clean the system thoroughly to remove dirt or debris in the pipe system in
order to prevent premature failure at initial startup.
• Verify controller settings match site conditions and motor nameplate data before
starting station.
Prestartup checklist
CAUTION:
Risk of leaks or flooding. Make sure to reinstall the drain plugs properly. Check all joints for
tightness and flange bolts for the proper torque.
Checks Checked
