USE ONLY HAYWARD GENUINE REPLACEMENT PARTS

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
–
Separation Hazard
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.
(Note: Pump model SP2305X7EESP is self priming to 8 ft. in less than 10 minutes.) 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 only 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.
CAUTION
– 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.
CAUTION
– Do NOT add chemicals to pool/spa system directly in front of pump suction. Adding
undiluted chemicals may damage pump and voids warranty.
CAUTION
– Before removing strainer cover:
1.
STOP PUMP before proceeding.
2.
CLOSE VALVES in suction and outlet pipes.
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.

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.

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.
CAUTION
– Allowing the pump to freeze with water in it will void the warranty.
