To Wire a Two-Speed Motor Wire the pump as shown in the diagram below. See Fig 3.9.3 Fig 3.9.3 4. Startup & Operation 4.1. Prior to Start-Up If it is necessary to perform a water pressure test prior to initial use to ensure plumbing system is functioning properly, then the following criteria should be maintained for this test: 1. Have a professional perform this test. 2. Ensure all Hayward pump and system components are removed from system prior to performing test. WARNING - If circulation equipment must remain in the plumbing system during water pressure test, do not apply more than 10 psi pressure to the system. Be sure water pressure has been released, using the filter manual air relief valve, before removing pump strainer cover. WARNING - All suction and discharge valves MUST be OPEN, as well as filter air relief valve (if available) on filter, when starting the circulating pump system. Failure to do so could result in severe personal injury. 4.2. Starting/Priming the Pump Pumps with single speed motors are self priming to 8 ft. and pumps with 2 speed motors are self priming to 8 ft. on high speed only. Rotate strainer cover counter clockwise to remove. Fill strainer housing with water to suction pipe level. Replace strainer cover, rotate clockwise and hand tighten. If water leakage occurs from anywhere on the pump or filter, DO NOT start the pump. If no leakage occurs, stand at least 10 feet from pump and/or filter and proceed with starting the pump. WARNING - Return to filter to close filter manual air relief valve when a steady stream of water (not air or air and water) is discharged from valve. Failure to do so could result in severe personal injury. ATTENTION - NEVER OPERATE THE PUMP WITHOUT WATER. Water acts as a coolant and lubricant for the mechanical shaft seal. NEVER run pump dry. Running pump dry may damage seals, causing leakage, flooding, and voids warranty. Fill strainer housing with water before starting motor. ATTENTION - Do NOT add chemicals to pool/spa system directly in front of pump suction. Adding undiluted chemicals may damage pump and voids warranty. ATTENTION - Before removing strainer cover: 1. STOP PUMP before proceeding. 2. CLOSE VALVES in suction and outlet pipes. Page 10 of 20 USE ONLY HAYWARD GENUINE REPLACEMENT PARTS Max-Flo XL Pump IS2300 Rev-A1
