Commissioning, Startup, Operation,

and Shutdown

Preparation for startup

DANGER:
Electrical hazard sufficient to kill. Always disconnect and lock out the power before you
service the unit.

WARNING:
Explosion hazard. Do not short battery terminals together or damage the battery.

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.

• 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 clear 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.
