STARTING ANd PRIMING INSTRUCTIONS
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.
MAINTENANCE
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. See instructions.
WINTERIZING / STORAGE
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.
TROUBLE SHOOTING GUIdE
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 Hayward 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 condi-
tion, 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 pumps, 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.
3. Block off suction as close to pump as possible and determine if pump will develop a vacuum.
a) If pump does not develop vacuum, and pump has sufficient «priming water»:
1. Tighten all bolts and fittings on suction side.
2. Check voltage to make sure pump is up to speed.
3. Open pump and check for clogging or obstruction.
4. Remove and replace shaft seal.
b) If pump develops a vacuum, check for blocked suction line or strainer, or air leak in suction piping.
E) Low flow - Generally, Check for :
1. Clogged or restricted strainer or suction line; undersized pool piping.
2. Plugged or restricted discharge line of filter (high discharge gauge reading).
3. Air leak in suction (bubbles issuing from return fittings).
4. Pump operating under speed (low voltage).
5. Plugged or restricted impeller.
