Fill strainer housing with water to suction pipe level. Never operate the pump without water. Water acts as a coolant and
lubricant for the mechanical shaft seal.
Open all suction and discharge valves, as well as air bleed (if available) on filter. (The air that is to be displaced from the
suction line must have someplace to go).
Turn on power and allow a reasonable time for priming. Five minutes is not unreasonable. (Priming time depends on suction
lift and horizontal length of suction piping). If pump will not start, or will not prime, see TROUBLE SHOOTING GUIDE.
1. Clean strainer basket regularly. Do not strike basket to clean. Inspect strainer cover gasket regularly and replace as
necessary.
2. Hayward pumps have self-lubricating motor bearings and shaft seals. No lubrication is necessary
3. Keep motor clean. Insure air vents are free from obstruction.
4. Occasionally, shaft seals become damaged or worn and must be replaced.
5. Except for cleaning activities, any repairing, servicing and maintenance has to be performed by a Hayward authorized
service agent or a similarly qualified person.
1. Drain pump by removing drain plug(s) and store in strainer basket.
2. Disconnect electrical wires and pipe connections, and store pump in a dry, well-ventilated room. Or, as a minimum
precaution: Disconnect electrical wires. Remove four bolts holding bracket and motor assembly to Strainer/Housing
and store assembly in a dry, well-ventilated room. Protect remaining Strainer/Housing assembly from the elements by
covering.
noTe: Before Re-Activating pump, thoroughly clean and remove scale, dirt, etc.
a) motor won't start
1. Check for improper or loose connections, open switches or relays, blown circuit breakers or fuses.
2. Manually check rotation of motor shaft for free movement and lack of obstruction.
B) motor cuts out - Check for :
1. Wiring, loose connections, etc.
2. Low voltage at motor (frequently caused by undersized wiring).
3 Binding and overload. (Amperage reading.).
noTe Your pump motor is equipped with Automatic Thermal Overload Protection. The motor will automatically shut-off,
under conditions before heat damage build-up, due to an improper operating condition, can occur. The motor will auto-
restart when safe heat level is reached.*
* This is only valid for 1 phase motors. 3 phase motors require the use of fuses which have to be reset.
C) motor hums, but does not start - Check for :
1. Governor stuck in open position.
2. Open capacitor.
D) Pump won't prime :
1. Make sure pump strainer/housing is filled with water, and that cover gasket is clean and properly sea-ted. Tighten hand
nuts.
2. Make sure all suction and discharge valves are open and unobstructed, and that pool water level is above all suction
openings.
