IMPORTANT SAFETY INSTRUCTIONS
When installing and using this electrical equipment, basic safety precautions should always be followed,
including the following: Failure to follow instructions may result in injury.
READ AND FOLLOW ALL INSTRUCTIONS
WARNING - To reduce risk of injury, do not permit children to use this product unless they are closely supervised at all times.
CAUTION - This pump is U.L. listed for permanently installed pools and may also be used with hot tubs and spas if so marked.
It is not U.L. listed for storable pools. A permanently installed pool is constructed in or on the ground and cannot be readily
disassembled for storage. A storable pool is constructed so that it may be readily disassembled for storage and reassembled to
its original integrity.
If installed within an outer enclosure or beneath the skirt of a hot tub or spa, adequate ventilation and free circulation of air must
be provided to prevent overheating of the motor.
Use motor bonding lug to connect the motor with other bonding parts using a #8 AWG conductor as required by electrical codes.
NOTE: If your pump is equipped with a 3 ft. (1 m) cord and twist lock plug, items 5 through 8 apply.
WARNING - Risk of Electric Shock. Connect only to a grounding-type receptacle protected by a ground fault circuit interrupter
(GFCI). Contact a qualified electrician if you cannot verify that the receptacle is protected by a GFCI.
Do not bury cord. Locate cord to minimize abuse from lawn mowers, hedge trimmers, and other equipment.
WARNING - To reduce the risk of electric shock, replace damaged cord immediately.
WARNING - To reduce the risk of electric shock, do not use extension cord to connect unit to electric supply; provide a properly
located outlet.

SAVE THESE INSTRUCTIONS
Forbestpump performance, locate thesystembelow the pool water line and as
close to the pool as practical. If you own an above-ground pool, NOTE:
ANSI/NSPI-4 Article V, standard for above-ground and
on-ground pools, advises that components such as the filtration
system, pumps and heater be positioned so as to prevent their
being used as means of access to the pool by young children.
Makesure suction joints are tight. Suction pipe should be aslarge or larger than
discharge pipe.
Damp,non-ventilatedlocationsshouldbeavoided.Motorsrequirefreecirculation
of air to aid in cooling.
Ensurethattheelectricalsupplyavailableagreeswiththemotor’s voltage,phase
and cycle, and that wire size is adequate for the HP (KW) rating and distance
from power source. Motor must always be properly grounded. If cord connected,
use only a properly grounded outlet.
Fill strainer housing with water to suction pipe level. Never operate the pump
withoutwater. Wateracts as a coolant and lubricant for the mechanical shaft seal.
CAUTION: All suction and discharge valves must be open when
starting the system. Failure to do so could cause severe personal
injury and/or property damage.
Turn on power and allow a reasonable time forpriming. Priming time depends on
suctionliftandhorizontal lengthof suctionpiping.Ifthepumpwillnotstart,orwill
not prime, see TROUBLE SHOOTING GUIDE on back page.
NOTE: 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.

*For Housing Cover with integral drain plug, order SP1500B1.

1. Clean strainer basket regularly. Do not strike basket to clean. Inspect
strainer cover gasket regularly and replace as necessary.
2. SwimPro pumps have self-lubricating motor bearings and shaft seals.
No lubrication is necessary.
3. Keep motor clean. Ensure air vents are free from obstruction.
4. Occasionally, shaft seals must be replaced, due to wear or damage.
See instructions.
GENERAL
Exercise extreme care in handling and installing the new
seal and ceramic 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.
Remove pump and motor assembly from piping system.
Remove pump housing cover (with strainer attached) by removing
the seven (7) housing bolts and nuts which fasten housing cover
to pump housing. The impeller is now exposed.
To remove impeller, insert screwdriver in slot at end of motor.*
Hold screwdriver so as to keep shaft from turning, and rotate the
impeller in a counterclockwise direction. The spring portion of the
seal assembly is now exposed.
Note carefully the position of the spring seal and pull it off the
impeller.
To remove the stationary (ceramic seat) part of the seal assembly:
a. Loosen the four (4) motor securing bolts and
disengage the motor from the pump housing.
b. With motor removed, press the clear plastic and
ceramic seat assembly out of the pump housing
recess. If tight, tap lightly from the “motor” side.
Clean and lubricate the impeller hub shaft and pump housing seal
recess with a dilute solution of non-granulated liquid-type soap.
Gently wipe the polished face of the new ceramic seat with a soft,
dry cotton cloth.
Press the new spring portion of the assembly onto the impeller,
black polished surface facing away from the impeller.
Carefully press ceramic seat, with O-ring, into clear plastic seat
retainer--polished surface facing out. Be sure O-ring is in place on cut
ridge of clear plastic retainer. Press plastic retainer, with ceramic seat
inside, into recess of pump housing--O-ring end first. Replace the
assembly firmly and evenly.
Carefully insert the motor shaft through the seat assembly and
secure motor to pump housing with four (4) motor securing bolts.
(Be sure motor base is positioned properly.)
Screw the impeller, with spring seal, onto the motor shaft, hand
tight, by turning clockwise.
Clean rubber gasket (replace if necessary) and fasten housing cover
to pump housing with seven (7) bolts and nuts. Tighten bolts and
nuts alternately and evenly.
Reconnect pump to piping system. Be sure to fill stainer with water
before restarting.
A separate electrical circuit, utilizing a rating as above, is recommended.
*For A.O. Smith Canopy Motors: Remove motor end cover and carefully apply wrench to flat on motor shaft to hold shaft from turning.

TROUBLE SHOOTING GUIDE
MOTOR WON’T START
MOTOR CUTS OUT
MOTOR HUMS, BUT DOES NOT START
PUMP WON’T PRIME
LOW FLOW
NOISY PUMP
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.
1. Wiring, loose connections, etc.
2. Low voltage at motor (frequently caused by undersized wiring).
3. Binding and overload (Amperage reading).
Note: Your SwimPro pump motor is equipped with Automatic Thermal Overload Protection. The motor
will automatically shut-off, under normal conditions, due to an improper operating condition,
before heat damage build-up can occur. The motor will auto-restart when safe heat level is
reached.
1. Centrifugal switch stuck in open position.
2. Binding of motor shaft.
1. Make sure strainer cover is locked firmly in position.
2. Make sure all suction and discharge lines and 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 develops a vacuum, check for blocked suction line or strainer, or air leak in suction piping.
b. If pump does not develop a vacuum and pump has sufficient “priming water”:
(1) Tighten all bolts and fittings.
(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.
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.
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.
