SAFETY
INSTRUCTIONS
Always follow basic safety pre-
cautions with this equipment, in-
cluding the following.
To reduce the risk of
injury, do not permit children to
use this product unless they are
closely supervised at all times.
This pump is for
use with permanently installed
pools and may also be used with
hot tubs and spas if so marked.
Do not use with storable pools. A
permanently installed pool is con-
structed in or on the ground or in
a building such that it cannot be
readily disassembled for storage.
A storable pool is constructed so
that it may be readily disassem-
bled for storage and reassembled
to its original integrity.

INSTALLATION
Installation and wiring of pump should only be done by qualified, licensed
personnel.
Pump mount must:
Be Solid - Level - Rigid - Vibration free. (To reduce vibration and pipe stress,
bolt pump to mount.)
Be installed with pump suction inlet higher than tub suction fitting. (This al-
lows pump to drain completely when tub is drained.)
Have pump suction below tub water level when pump is running.
Be protected from excess moisture.
Allow adequate access for servicing pump and piping.
Ventilation:
Provide adequate ventilation to prevent motor overheating.
For continuous running, motor hot air exhaust must be able to escape tub
motor compartment.
Piping:
Use flexible or rigid PVC pipe for connections to pump.
Use at least 1-1/2" IPS pipe.
Fittings restrict flow; for best efficiency use fewest possible fittings.
Unions are provided. Use as follows for leak-free connections 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:
Size and number of jets will have a major effect on jet action.
Typical installations use up to four 7/8" or 3/4" diameter jets or up to seven
1/2" diameter jets.
Tub fittings must meet International Association of Plumbing and Mechanical
Officials (IAPMO) standards for jetted bathtubs. Use only non-entrapping suc-
tion fitting or double suction.

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 Volt or 230
Volt single phase only)! Incorrect voltage can cause fire or seriously
damage motor and voids warranty!
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 1).
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 1). Use solid copper conductor No. 8 AWG (8.4mm2)
or larger.
Wiring:
Pump must be permanently connected to circuit. Table I, Page 6, gives correct
wire and circuit breaker sizes for the pump alone. If other lights or appliances
are also on the same circuit, be sure to add their amp loads to pump amp load
before figuring wire and circuit breaker sizes. (If unsure how to do this or if
this is confusing, consult a licensed electrician.) Use the load circuit breaker
as the master on-off switch.
Install a Ground Fault Circuit Interrupter (GFCI) in circuit; it will sense a short-
circuit to ground and disconnect power before it becomes dangerous to pool
users. For size of GFCI required and test procedures for GFCI, see manufac-
turer’s instruction.
In case of power outage, check GFCI for tripping (which will prevent normal
pump operation). Reset if necessary.
NOTICE: If you do not use conduit when wiring motor, be sure to seal wire
opening on end of motor to prevent dirt, bugs, etc., from entering.
Hazardous voltage.
Can shock, burn,
or cause death.

Voltage:
Voltage at motor must be not more than 10% above or below motor name-
plate rated voltage or motor may overheat, causing overload tripping and re-
duced 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.
Values given in tables below are for PUMP MOTOR ONLY. If addi-
tional spa accessories are installed on pump motor circuit (heater,
blower, etc.), include their amperage draw when figuring wire and circuit
breaker sizes.

to motor before working on pump or motor!
No lubrication or regular maintenance are needed.
If shaft seal is damaged, repair as follows:
Removing Old Seal:
1. Disconnect power to pump motor.
2. Drain tub and pump; disconnect unions to allow access to pump.
3. Remove six 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 un-
screw impeller from shaft (turn counterclockwise). 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 2). Do not damage impeller
surface where drive ring seats and seals.
6. Carefully remove four motor throughbolts from seal plate (Figure 3); remove
seal plate and use a screwdriver to tap ceramic seat out from the rear
(Figure 4). Do not damage seal cavity in seal plate.
7. Clean cavity from which seal was removed and clean motor shaft.
Installing New Seal:
1. Ceramic seat must be clean and free of dirt, grease, dust, etc. Wet rubber
cup gasket of ceramic seat with small amount of liquid detergent; press into
cavity firmly and squarely with finger pressure (Figure 5).
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 impeller
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).
