and set to the duty point. Start up of the engine and controllers shall be as given in their respective IOM manuals.
Automatic starting of the pumps shall be based on pressure setting.
6.3. Methods of Stopping
Manual:
Manual shut down shall be accomplished by operation of push-button on the outside of the controller enclosure.
Automatic shutdown after automatic start:
