15. Self Priming Cycle 1. Fill pump with initial priming charge. 2. Start pump, impeller pulls liquid from trap 3. Mixture of Air/Liquid is expelled into the separator. into the separator. 4. Air is expelled thru discharge. 6. Cycle continues until all air is evacuated from line. 5. Liquid re-enters casing/trap thru second throat to priming chamber.
