3. RELEASE ALL PRESSURE from pump and piping system using filter manual air relief valve. See filter owner's manual for more details. 4. If water source is higher than the pump, pump will prime itself when suction and outlet valves are opened. If water source is lower than the pump, unscrew and remove strainer cover; fill strainer housing with water. 5. Clean and lubricate strainer cover O-ring with "Jack's 327" if necessary. 6. Replace strainer cover on strainer housing; turn clockwise to tighten cover. NOTE - Tighten strainer cover lock ring by hand only (no wrenches). Turn on power and wait for pump to prime, which can take up to fifteen (15) minutes. Priming time will depend on vertical length of suction lift and horizontal length of suction pipe. If pump does NOT prime within 15 minutes, stop motor and determine cause. Be sure all suction and discharge valves are open when pump is running. See Troubleshooting Guide. 5. Maintenance  Clean strainer basket regularly. Do NOT strike basket to clean. Inspect strainer cover gasket regularly and replace as necessary.  Hayward pumps have self-lubricating motor bearings and shaft seals. No lubrication is necessary.  Keep motor clean. Insure motor air vents are free from obstruction to avoid damage. Do NOT use water to hose off motor.  Occasionally, shaft seals must be replaced, due to wear or damage. Replace with genuine Hayward seal assembly kit. See "Shaft Seal Change Instructions" in this manual. 6. Storage / Winterization WARNING - Separation Hazard. Do not purge the system with compressed air. Purging the system with compressed air can cause components to explode, with risk of severe injury or death to anyone nearby. Use only a low pressure (below 5 PSI), high volume blower when air purging the pump, filter, or piping. ATTENTION - Allowing the pump to freeze with water in it will void the warranty. ATTENTION - Use ONLY propylene glycol as antifreeze in your pool/spa system. Propylene glycol is non- toxic and will not damage plastic system components; other anti-freezes are highly toxic and may damage plastic components in the system. Drain all water from pump and piping when expecting freezing temperatures or when storing pump for a long time (see instructions below). Gravity drain system as far as possible. Keep motor dry and covered during storage. To avoid condensation/corrosion problems, do NOT cover or wrap pump with plastic film or bags. 6.1. Storing Pump For Winterization WARNING - To avoid dangerous or fatal electrical shock hazard, turn OFF power to motor before draining pump. Failure to disconnect power may result in serious personal injury or death. 1. Drain water level below all inlets to the pool. 2. Remove drain plugs and strainer cover from strainer housing. (See "Parts Diagram" in section 8.1 of this manual for pump component locations.) 3. Disconnect pump from mounting pad, wiring (after power has been turned OFF), and piping. 4. Once the pump is fully drained of water, re-install the strainer cover and drain plugs. Store pump in a dry area. Page 11 of 20 USE ONLY HAYWARD GENUINE REPLACEMENT PARTS Max-Flo XL Pump IS2300 Rev-A1
