Instructions / Assembly

USE ONLY HAYWARD GENUINE REPLACEMENT PARTS 7
NOTICE – 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.
NOTICE – Do NOT add chemicals to pool/spa system directly in front of pump suction. Adding undiluted
chemicals may damage pump and voids warranty.
NOTICE – 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" each time it is removed. Inspect O-ring and
re-install on strainer cover.
6. Replace strainer cover on strainer housing; turn strainer cover hand knobs clockwise to tighten cover.
NOTE - Tighten strainer cover knobs by hand only (no wrenches).
7. OPEN VALVES in suction and outlet pipes.
Before re-starting pump, see “Starting/Priming the Pump” instructions.
NOTICE – Wait five (5) seconds before re-starting pump. Failure to do so may cause reverse rotation of motor and
consequent serious pump damage.
Turn on power and wait for pump to prime, which may take up to five (5) minutes. Priming time will depend on
vertical length of suction lift and horizontal length of suction pipe. If pump does NOT prime within five 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 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. Purging the system with compressed air can cause components to
explode, with risk of severe injury or death. To avoid, do not purge the system with compressed air. Use only a low
pressure (below 5 PSI), high volume blower when air purging the pump, filter, or piping.
NOTICE – Allowing the pump to freeze will void the warranty.
NOTICE
–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).
Keep motor dry and covered during storage. To avoid condensation/corrosion problems, do NOT cover or wrap pump
with plastic film or bags.
Storing Pump for Winterization
WARNING – Electrical Hazard - Failure to disconnect power may result in serious personal injury or
death. To avoid, turn OFF power to motor before draining pump.
1. Drain water level below all inlets to the pool.
2. Remove drain plugs from bottom of strainer body, and remove strainer cover from strainer housing.
3. Disconnect pump from mounting pad, wiring system (after power has been turned OFF), and piping system.
4. Once the pump is drained of water, re-install the strainer cover and drain plugs. Store pump in a dry area.
