INSTALLATION
Installation and wiring of pump should only be done by qualified, li-
censed personnel.
For self-priming pumps, locate the pump as close as possible to the
pool and not more than 3 feet above pool water level.
For ease of pump/motor removal, install pipe unions on the suction and
discharge pipes close to the pump.
Pump mount must:
• Be solid - level - rigid - vibration free. (To reduce vibration and pipe
stress, bolt pump to mount).
• Allow pump suction inlet height at or below water level in pool.
• Allow use of short, direction suction pipe (to reduce friction losses).
• Allow for gate valves in suction and discharge piping.
• Have adequate floor drainage to prevent flooding.
• Be protected from excess moisture.
• Allow adequate access for servicing pump and piping. Include gate
valves in suction and discharge piping.
NOTICE: Use Teflon tape or Plasto-Joint Stik1for making all threaded
connections to the pump. Do not use pipe dope; pipe dope will cause
stress cracking in the pump. See Figure 4.
NOTICE: Pump suction and discharge connections have molded in
thread stops. DO NOT try to screw pipe in beyond these stops.
Tighten the pump/trap fittings only as much as it is required to insure a
tight connection (1-1/2 turns past hand tight is sufficient).
Overtightening may damage the pump or trap. Use care when using
teflon tape as friction is reduced considerably; do not overtighten con-
nections or damage may occur. See Figure 5.

Teflon Taping Instructions
•Use only new or clean PVC pipe fittings.
• Wrap male pipe thread with one or two layers of teflon tape, winding
tape clockwise as you face the start of thread. Cover entire thread por-
tion of pipe. See Figure 6.
• If leaks occur, remove pipe, clean off old tape, rewrap with one to two
additional layers of tape and remake the connection.
•NOTICE: Support all piping connected with pump! See Figure 7.
Piping:
•Use at least 1-1/2” PVC pipe. Increase size if a long run is needed.
• If large than 1-1/2” pipe is used, then use a pipe reducing fitting at the
pump/trap ports to match the pipe size.
• To avoid strains on the pump, support both suction and discharge pipes
independently. Place these supports near the pump. See Figure 7.
• To avoid a strain left by a gap at the last connection, start all piping at
the pump and run pipe away from the pump.
• Never use a suction pipe smaller than pump suction connections.
• To avoid airlocking, slope suction pipe slightly upward toward the
pump. See Figure 8.
•NOTICE: To prevent flooding when removing pump for service, all
flooded suction systems must have gate valves in suction and discharge
pipes.
• Plastic pipe will expand and contract as the temperature changes. To
allow for this, use an expansion joint or flexible piping.
• Unions are provided. Use as follows for leak-free connection to pump:
1. “O” Ring and sealing surfaces must be clean.
2. Assemble handtight only! (NO WRENCHES!)
3. NO pipe compound or Teflon tape on unions.
4. Bond pipe to unions with PVC cement.
Use PVC cement only in a well ventilated area away from flame;
FOLLOW MANUFACTURER‘S INSTRUCTIONS!
Fittings:
•Fittings restrict flow; for best efficiency use fewest possible fittings.
• Avoid fittings which could cause an air trap.
• Pool and spa fittings must conform to International Association of
Plumbing and Mechanical Officials (IAPMO) standards.
• Use only non-entrapping suction fitting in pool or double suction (skim-
mer & main drain).

ELECTRICAL
Ground motor before connecting to electrical power supply! Failure to
ground pump motor can cause serious or fatal electrical shock hazard!
Do not ground to a gas supply line!
To avoid dangerous or fatal electrical shock, turn OFF power to motor
before working on electrical connections.
GFCI tripping indicates an electrical problem. If GFCI trips and will not
reset, have a qualified electrician inspect and repair electrical system.
Exactly match supply voltage to nameplate voltage (115 or 230 Volt
single phase only)! Incorrect voltage can cause fire or seriously damage
motor and voids warranty! See Figure 10.
Grounding:
•Install, ground, and wire motor according to local or National Electrical
Code requirements.
• Permanently ground motor; use size and type wire required by code.
• Ground connection must be made to green grounding terminal under
motor canopy or access plate (see Figure 9).
• Connect motor ground terminal to electrical service ground.
• Install and bond pump according to local codes and ordinances; use
bonding lug on motor (see Figure 9). Use solid copper conductor No. 8
AWG (8.4 sq. mm) or larger.
• Connect a No. 8 AWG (8.4 sq. mm) solid copper bonding wire to the
pressure wire connector provided on the motor housing and to all metal
parts of the swimming pool, spa, or hot tub and to all electrical equip-
ment, metal piping or conduit within 5 feet (1.5 m) of the inside walls of
swimming pool, spa, or hot tub.
Wiring:
•Use Ground Fault Circuit Interrupter (GFCI) as master on-off switch; it
will sense a short circuit to ground and disconnect power before it be-
comes dangerous to pool users. Test GFCI according to manufacturer’s
instructions.
• In case of power outage, check GFCI for tripping (which will prevent
normal water circulation); reset if necessary.
• Permanently connect pump to circuit; do not connect any other lights
or appliances to the same circuit.
• Match wire size and circuit breaker size to Table I, Page 4.
• Use wire rated at 75°C.
Voltage:
•Voltage at motor must be not more than 10% above or below motor
nameplate rated voltage or motor may overheat, causing overload trip-
ping and reduced component life. If voltage is less than 90% or more
than 110% of rated voltage when motor is running at full load, consult
power company.

OPERATION
NEVER run pump dry! Running pump dry may damage seals, causing
leakage and flooding! Fill pump with water before starting motor.
Do not add chemicals to pool/spa system directly in front of pump suc-
tion. Adding undiluted chemicals may damage pump and voids
warranty.
Before removing trap cover:
1. STOP PUMP before proceeding.
2. CLOSE GATE VALVES in suction and discharge pipes.
3. RELEASE ALL PRESSURE from pump and piping system.
If pump is being pressure tested, be sure pressure has been released be-
fore removing trap cover!
Do not block pump suction! To do so with body may cause severe or
fatal injury. Small children using pool must ALWAYS have close adult
supervision!
NOTICE: Do not block pool return or spa jets! To do so may flood area
causing damage to equipment and water damage to surrounding area.
Priming Pump:
•Open gate valves before starting system.
• Release all air from filter and piping system: see filter owner’s manual.
• In a flooded suction system (water source higher than pump), pump will
prime itself when suction and discharge valves are opened.
• If pump is not in a flooded suction system, unscrew and remove trap
cover; fill trap and pump with water. See Figure 11.
• Lubricate trap cover O-Ring with petroleum jelly each time it is re-
moved.
• Clean and inspect O-Ring; reinstall on trap cover.
• Replace trap cover on trap; turn clockwise to tighten cover.
NOTICE: Tighten trap cover by hand only (no wrenches)! Use a
wrench only if necessary to remove lid!
Pump should prime now. Priming time will depend on vertical length of
suction lift and horizontal length of suction piping.
• If pump does not prime within ten minutes, stop motor and find cause.
Be sure all suction and discharge valves are open when pump is run-
ning. See Troubleshooting Guide, Page 11.
Pool, Spa or Tub Water:
•Keep water level at least two inches above bottom of skimmer opening
when system is not in use. Failure to do so can allow air to enter sys-
tem, causing pump to lose its prime.
• Keep water temperature at 104°F or below for spa/tubs and 80°F for
pools.
• If in doubt, start a a lower temperature and gradually increase it accord-
ing to your experience.
• Keep an accurate thermometer in pool/spa; check it before getting in.
• Keep pool water “balanced”. Maintain the water pH between 7.2 and
7.6.
Do not use or allow the use of the spa/pool by anyone using alcohol or
drugs. The effects of hot water, alcohol and/or drugs can cause dizzi-
ness and falling, loss of consciousness, or heart attack.

Be sure to prime pump (Page 8) before starting.
Before removing trap cover or front plate bolts:
1. STOP PUMP before proceeding.
2. CLOSE GATE VALVES in suction and discharge pipes.
3. RELEASE ALL PRESSURE from pump and piping system.
To avoid dangerous or fatal electrical shock hazard, turn
OFF power to motor before working on pump or motor!
•Aside from lubricating trap cover O-Ring, no lubrication or regular
maintenance is needed beyond reasonable care and periodic cleaning
of the trap basket.
• If shaft seal is worn or damaged, repair as follows:
Removing Old Seal:
1. Disconnect power supply to motor.
2. Close suction/discharge valves and drain pump. Remove pump, hold
down bolts, disconnect unions or hose clamps, and remove pump from
system.
3. Remove 6 bolts holding front plate to seal plate; remove front plate.
4. Remove shaft cover or motor canopy; using screwdriver in slot on motor
end of shaft or wrench on flats of shaft extension, hold pump shaft and
unscrew impeller from shaft (turn counter-clockwise). Rotating half of
seal will come off with impeller.
5. Carefully remove rotating part of seal from impeller sleeve by pulling
and turning on sealing washer and spring (Figure 12). Do not damage
impeller surface where drive ring seats and seals.
6. Carefully remove four motor throughbolts from seal plate (Figure 13); re-
move seal plate and use a screwdriver to tap ceramic seat out from the
rear (Figure 14). Do not damage seal cavity in seal plate.
7. Clean cavity from which seal was removed and clean motor shaft.
Pump Reassembly/Installing New Seal:
1. Ceramic seat must be clean and free of dirt, grease, dust, etc. Wet rub-
ber cup gasket of ceramic seat with small amount of water; press into
cavity firmly and squarely with finger pressure (Figure 15).
2. If ceramic seat will not locate properly, remove it, place face up on
bench, and reclean cavity. Ceramic seat should now locate.
3. Seal must be free of dirt, grease, grit, scratches or chips; be sure im-
peller sleeve is clean. Slide seal assembly, rubber drive ring first, onto
impeller sleeve until drive ring bottoms on impeller back shroud.
4. Slip slinger over shaft; remount seal plate. Torque throughbolts to 25
inch-lbs. (29 cm-kg).
5. Screw impeller onto shaft until it seats against shaft shoulder. Work
slinger over end of impeller sleeve so it rides on sleeve (Figure 16).
6. Remount front plate; using pattern shown in Figure 17, torque bolts to
30 inch-lbs. (35 cm-kg). BE SURE to start with bolt in 3 o’clock position
as shown.
