GENERAL TIPS ON PRODUCT INSTALLATION

Locate the pump as close to pool as practical and run suction line as direct as possible. This cuts down on friction loss through pipe and fittings.
Never overtighten pipe connections—use only pipe sealants formulated specifically for plastics, i.e., Teflon tape, Permatex No. 2, etc.
Suction line should have continuous slope from lowest point in line. Make sure suction joints are tight. Suction pipe should be as large or larger than discharge pipe.
Damp, non-ventilated locations should be avoided. Motors require free circulation of air to aid in cooling.
Insure that the electrical supply available agrees with the motor's voltage, phase and cycle, and that wire size is adequate for the HP rating and distance from power source. Motor must always be properly grounded. If cord connected, use only a properly grounded outlet. Electrical circuits must be protected by proper size ground fault circuit interrupter (GFCI) as required by applicable electrical codes. All electrical wiring must be performed by qualified personnel, and must conform to local codes and regulations. Three Phase Motors are supplied with either six (6) or nine (9) motor leads that must be connected according to the wiring schematic provided on the motor data plate for the correct field supply voltage. Three Phase Motors require the installation of a properly sized magnetic motor starter to provide overload protection for the motor. Consult qualified electrical personnel.

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 lines and valves, as well as air bleed (if available) on filter. (The air that is to be displaced from the suction line must have some place to go.)

All suction and discharge valves must be open when starting system. Failure to do so could cause severe personal injury and/or property damage.

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 the pump will not start, or will not prime, see TROUBLE SHOOTING GUIDE.

PRODUCT PARTS

MAINTENANCE

1. Clean strainer basket regularly. Do not strike basket to clean. Inspect strainer cover O-ring 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.

STORAGE/WINTERIZING

1. Drain pump by removing drain plug(s) and store in strainer basket.
2. Disconnect electrical wires and pipe connections, and store pump in dry, well-ventilated room. Or:
   Disconnect electrical wires. Remove six (6) 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 reactivating pump, thoroughly clean and remove scale, dirt, etc.

SEAL CHANGE INSTRUCTIONS

SP3000 SERIES
GENERAL
Exercise extreme care in handling and installing the new seal and seat assembly.
The lapped and polished surfaces may easily be damaged by dirt or scratching.

For safety, all service must be performed with all power shut off.

REMOVING THE MOTOR ASSEMBLY

1. Remove the six (6) 3/8" x 2" hex head bolts which hold the motor assembly to the pump housing.
2. Slide the motor assembly out of the pump/strainer housing, exposing the diffuser. Pull the diffuser off of the seal plate, exposing the impeller. (The diffuser may remain in the pump/strainer housing. To remove, pull it straight out of the housing.)

REMOVING THE IMPELLER

(see note)

3. Remove the motor end cover by removing the two (2) or three (3) screws.*
4. Hold motor shaft from turning by placing wrench over the two (2) flats on the motor shaft.
5. Rotate the impeller counter-clockwise and remove. The spring portion of the seal assembly is now exposed. Note carefully the position of the spring seal, and remove it.
   NOTE: Replace motor cover to protect delicate motor parts.

REMOVING THE CERAMIC SEAT

6. Remove the seal plate. Note the notch on the top of the plate and the mating lug on the top of the motor mounting bracket.
7. Press the ceramic seat with O-ring out of the seal plate. If tight, use a small screwdriver to tap seat out.

STOP—Clean all recesses and parts to be reassembled. Inspect gaskets and replace if necessary.

SEAL INSTALLATION

8. Clean and lubricate the impeller hub shaft and pump housing seal recess with a dilute solution of non-granulated liquid-type soap. The use of petroleum or silicone lubricants may contribute to seal leakage.
9. Gently wipe the black, polished surface of the spring seal assembly with a clean, soft cotton cloth. Press the spring seal assembly onto the impeller hub—black polished surface facing away from the impeller.
10. Gently wipe the polished face of the ceramic seat with a soft, cotton cloth. Lubricate the O-ring on the ceramic seat and press it firmly and evenly into the recess of the seal plate—polished side facing out.
11. Place the seal plate onto the motor mounting bracket aligning the positioning lug and guide.

REPLACING THE IMPELLER AND DIFFUSER

12. Screw the impeller onto the motor shaft in a clockwise direction. Tighten snugly by holding motor shaft with wrench.
13. Place the diffuser over the impeller onto the seal plate, fitting positioning lug between the two guides.

REPLACING THE MOTOR ASSEMBLY

14. Slide the motor assembly, with the diffuser in place, into pump/strainer housing, being careful not to dislodge the diffuser.
15. Fasten assembly to housing using the six (6) 3/8" x 2" bolts. (Be sure housing gasket is in place.) Tighten alternately and evenly.

*For motors without removable end cover - pry off cap at rear center of motor. Place large screwdriver in slot end of shaft to keep shaft from turning.
NOTE: For models equipped with Impeller Ring - remove impeller ring from front hub of impeller. When reassembling, be sure to replace it on impeller hub, larger end facing diffuser, before placing diffuser over the impeller.

TROUBLE SHOOTING GUIDE

1. 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.

2. 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)

3. THE UNIT WON'T PRIME

1. Make sure pump/strainer housing is filled with water, and that cover gasket is clean and properly seated. Tighten strainer cover.
2. Make sure all suction and discharge valves are open and unobstructed, and that pool water is above all suction openings.
3. Block off suction as close to pump as possible and determine if pump will develop a vacuum.
   1. 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.
   2. If pump develops a vacuum, check for blocked suction line or strainer, or air leak in suction piping.

4. 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 underspeed (low voltage).
5. Plugged or restricted impeller.

5. NOISY UNIT

Check for:

1. Air leak in suction causing rumbling in pump.
2. Cavitation due to restricted or undersized suction line and unrestricted discharge lines. Correct suction condition or throttle discharge lines, if practical.
3. Vibration due to improper mounting, etc.
4. Foreign matter in pump housing.
5. Motor bearings made unserviceable by wear, rust, or continual overheating.
