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
Only qualified, licensed personnel should install pump and wiring.
Pump mount must:
Be solid - Level - Rigid - Vibration free. (To reduce vibration and pipe stress,
bolt pump to mount.)
Allow pump suction inlet height to be as close to water level as possible.
Allow use of short, direct 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.
NOTICE: Use Teflon tape or Plasto-Joint Stik1 for making all threaded
connections to the pump. Do not use pipe dope; pipe dope will cause stress
cracking in the pump.
NOTICE: Pump suction and discharge connections have molded in thread
stops. DO NOT try to screw pipe in beyond these stops.
Teflon Taping Instructions:
Use only new or clean PVC pipe fittings.
Wrap male pipe threads with one to two layers of Teflon tape. Cover entire
threaded portion of pipe.
Do not overtighten or tighten past thread stop in pump port!
If leaks occur, remove pipe, clean off old tape, rewrap with one to two addi-
tional layers of tape and remake the connection.
NOTICE: Support all piping connected with pump!

Piping:
Use at least 1-1/4" (32mm) IPS PVC. Increase size if a long run is needed.
To avoid strains on the pump, support both suction and discharge pipes inde-
pendently. Place these supports near the pump.
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 connection.
To avoid airlocking, slope suction pipe slightly upward toward the pump.
NOTICE: To prevent flooding when removing pump for service, all flooded
suction systems must have gate valves in suction and discharge pipes.
Fittings:
Fittings restrict flow; for best efficiency use fewest possible fittings.
Avoid fittings which could cause an air trap.
Pool fittings must conform to International Association of Plumbing and
Mechanical Officials (IAPMO) standards.
Use only non-entrapping suction fitting or double suction.
ELECTRICAL
Ground motor before connecting to electrical power supply. Failure to
ground motor can cause severe 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.
Ground Fault Circuit Interrupter (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 single
phase only). Incorrect voltage can cause fire or seriously damage motor
and voids warranty. If in doubt consult a licensed electrician.
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.
Grounding/Bonding
Install, ground, bond and wire motor according to local or National Electrical
Code requirements.
Permanently ground motor. Use green ground terminal provided under motor
canopy or access plate (See Figure 2); use size and type wire required by
code. Connect motor ground terminal to electrical service ground.
Bond motor to pool structure. Use a solid copper conductor, size No. 8 AWG
(8.4 sq. mm) or larger. Run wire from external bonding lug (see Figure 2) to
reinforcing rod or mesh.
Hazardous voltage.
Can shock, burn,
or cause death.

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 equipment, metal piping
or conduit within 5 feet (1.5 m) of the inside walls of swimming pool, spa, or
hot tub.
Wiring
Pump must be permanently connected to circuit. Table I 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.
Values given in table below are for PUMP ONLY. If additional acces-
sories are installed on pump motor circuit (heater, blower, etc.), in-
clude their amerage draw when figuring wire and circuit breaker sizes.

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 spa system directly in front of pump suction.
Adding undiluted chemicals may damage pump and voids warranty.
Open gate valves before starting system.
Pump will prime itself when used in flooded suction system.
Be sure to release all air from filter and piping system; see spa/filter owner’s
manual.
On 2-Speed models, low speed is used for filtration and heating; high speed
provides therapy jet action.
Do not block pump suction. To do so with body may cause severe or
fatal injury. Small children using spa must ALWAYS have close adult
supervision.
•Tub should have dual suction outlets to prevent body or hair entrapment.
•Use only tub suction fittings certified to meet ASME/ANSI standard
A112.19.8M-1987.
NOTICE: Do not block pool return or spa jets! To do so may flood area caus-
ing damage to equipment and water damage to surrounding area.
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 system, causing
pump to lose its prime.
Keep water temperature at 104°F (40°C) or below.
Age or health conditions may require a lower temperature; consult a physi-
cian for more information.
If in doubt, start at a lower temperature and gradually increase it according to
your experience.
Keep an accurate thermometer in bath; check it before getting in.
Do not use or allow the use of the spa 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.
A long bath in hot water may cause hyperthermia (too much heat in
the body) which can be fatal. Some symtoms of hyperthermia are:
• Nausea
• Dizziness
• Fainting
If these symptoms appear while in the spa, GET OUT AT ONCE!
Cool the body at once with cold towels or a cool shower.
Call a doctor if symtoms do not go away.
Hazardous suction.
Can trap hair or
body parts, causing
severe injury
or death.
Do not block
suction.
Too much heat
can cause nausea,
dizziness, fainting or
death.
Check temperature
before using spa.

Draining Pump
To avoid dangerous or fatal electrical shock hazard, turn OFF power to
motor before draining pump.
Storage/Winterizing:
Explosion hazard. Purging the system with compressed air can
cause components to explode, with risk of severe injury or death to anyone
nearby. Use only a low pressure (below 5 PSI), high volume blower when air
purging the pump, filter, or piping.
NOTICE: Allowing pump to freeze will damage pump and void warranty!
NOTICE: Do not use anti-freeze solutions (except propylene glycol) in your
pool/spa system. Propylene glycol is non-toxic and will not damage plastic
system components; other anti-freezes are highly toxic and may also damage
plastic components in the system.
Drain all water from pump and piping when expecting freezing temperatures
or when storing pump for a long time (see instructions below).
Keep motor dry and covered during storage.
To avoid condensation/corrosion problems, do not cover pump with plastic.
For outdoor/unprotected installations:
1. Gravity drain system as far as possible.
2. Protect areas which retain water with non-toxic propylene glycol antifreeze
(“RV antifreeze”).
3. Enclose entire system in a weatherproof enclosure.
4. To avoid condensation/corrosion damage, allow ventilation; do not wrap
system in plastic.
5. Use a 40% propylene glycol/60% water solution to protect pump to
-50 degrees F (-46 degrees C).
Startup For Winterized Equipment
1. Remove any temporary weather protection placed around system.
2. Follow filter manufacturer’s instructions for reactivation of the filter.
3. Inspect all electrical wiring for damage or deterioration over the shutdown
period. Have a qualified serviceman repair wiring as needed.
4. Inspect and tighten all watertight connections.
5. Open all valves in suction and return piping.
6. Remove any winterizing plugs in piping system.
7. Drain all antifreeze from system.
8. Close all drain valves and replace all drain plugs in piping system.
9. Prime pump according to instructions on Page 7.

TROUBLESHOOTING GUIDE
Read and understand safety and operating instructions in this manual
before doing any work on pump!
Only qualified personnel should electrically test pump motor!
Pump does not operate:
1. Check GFCI for proper operation according to GFCI manufacturer’s instru-
tions.
2. Check for plugged impeller. Follow disassembly/assembly instructions
under “Pump Service”, Page 8.
3. Consult dealer/installer or service representative.
Inadequate circulation or jet action:
1. Check for blocked fittings. Block fittings will cause poor flow and poor jet
action.
2. Consult dealer/installer or service representative.
Excessive air in system - pump loses prime:
1. Make sure water level is at least 2” (51mm) above top of jets with system
not operating.
2. Make sure there are no leaks in suction piping.
3. Make sure ther is no vortex (whirlpool) at the suction.
4. Consult dealer/installer or service representative.
Circuit breaker in home panel trips repeatedly:
1. Breaker must be of adequate capacity.
2. For GFCI breaker: test according to GFCI manufacturer’s instructions.
3. Be sure no other lights and appliances are on circuit.
4. Consult dealer/installer or service representative.
Mechanical troubles and noise:
1. If pump suction and discharge piping are not adequately supported, pump
assembly will be strained. See “Installation”, Page 4.
2. Do not mount pump on a wooden platform! Securely mount on a con-
crete platform for quietest performance.
3. Air leak in suction line (bubbles in water returning to pool). Repair leak.
Tighten trap lid.
4. Foreign matter (gravel, metal, etc.) in pump impeller. Disassemble pump,
clean impeller, follow “Pump Serivce” instructions on Page 8 for
reassembly.
5. Cavitation.
Improve suction conditions by increasing pipe size, decreasing number of
