                    1250 gpm (4732 L/min) or less.

            (3)   The time required to prime the pump must not exceed 45 seconds if the rated capacity is

                    1500 gpm (5678 L/min) or more.

            (4)   An additional 15 seconds must be permitted  when the pump system includes an auxiliary
