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.

SAVE THESE

INSTRUCTIONS

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.

To reduce the risk of fire, keep all leaves, debris, or other foreign matter from

collecting around pump motor. Modern motors run at high temperatures. Do

not touch while running. If motor requires service, let it cool for 20 minutes

before trying to work on it.

NOTICE: Use Teflon tape or Plasto-Joint Stik1 for making all threaded connec-

tions to the pump. Do not use pipe dope; pipe dope will cause stress cracking

in the plastic pipe and fittings.

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!

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" IPS PVC pipe for pump suction. Increase size if a long run

is needed.

To avoid strains on the pump, support both suction and discharge pipes

independently. 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.

To reduce risk of suction entrapment, do not exceed the rated flow rate of the

suction fittings.

POOL PUMP SUCTION

REQUIREMENTS

Pump suction is hazardous and can trap and drown or disem-

bowel bathers. Do not use or operate swimming pools, spas, or hot tubs if a

suction outlet cover is missing, broken, or loose. Follow the guidelines below

for a pump installation which minimizes risk to users of pools, spas, and hot

tubs.

Entrapment Protection

The pump suction system

must

provide protection against the hazard of

suction entrapment or hair entrapment/entanglement.

Suction Outlet Covers

All suction outlet covers must be maintained. They must be replaced if

cracked, broken, or missing.

See below for outlet cover certification requirements.

All suction outlets must have correctly installed, screw-fastened covers in

place.

Testing and Certification

Suction outlet covers must have been tested by a nationally recognized testing

laboratory and found to comply with the lastest ASME/ANSI Specification for

Suction Fittings For Use in Swimming Pools, Spas, Hot Tubs, and Whirlpool

Bathtub Applications.

Outlets Per Pump (see Figure 1)

Provide at least two hydraulically balanced main drains, with covers, for each

swimming pool pump suction line. The centers of the main drains (suction fit-

tings) must be at least three feet apart.

Figure 1 – Recommended pump suction layout.

The system must be built so that it cannot operate with the pump drawing

water from only

one

main drain (that is, there must be at least two main drains

connected to the pump whenever it is running). However, if two main drains

run into a single suction line, the single suction line may be equipped with a

valve which will shutoff

both

main drains from the pump.

More than one pump can be connected to a single suction line as long as the

requirements above are met.

Water Velocity

The maximum water velocity through any suction outlet must be 1.5 feet per

second unless the outlet complies with the latest ASME/SNSI Specification for

Suction Fittings For Use in Swimming Pools, Spas, Hot Tubs, and Whirlpool

Bathtub Applications.

In any case, do not exceed the suction fittings maxi-

mum designed flow rate.

If 100% of the pump’s flow comes from the main drain system, the maximum

water velocity in the pump suction hydraulic system must be six feet per sec-

ond or less even if one main drain (suction fitting) is completely blocked. The

flow through the remaining main drain(s) must comply with the latest

ASME/ANSI Specification for

Suction Fittings For Use in Swimming Pools,

Spas, Hot Tubs, and Whirlpool Bathtub Applications.

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. 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.

Ground wire must be a copper conductor. It should be the same size as the

current-carrying wires to the motor, but not smaller than No. 12 AWG.

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.

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. See Table I, for 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.

OPERATION

NOTICE: Maximum operating pressure is 50 PSI.

NOTICE: NEVER run pump dry. Running pump dry may damage seals, caus-

ing leakage and flooding. Fill pump with water before starting motor.

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.

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.

Motor normally operates at high temperature and will be too hot

to touch. It is protected from heat damage during operation by an automatic in-

ternal cutoff switch. Before handling pump or motor, stop motor and allow it to

cool for 20 minutes.

Priming Pump

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 does not prime, make sure that all valves are open, suction pipe end

is under water, pump suction is below water level, and that there are no leaks

in suction pipe. See Troubleshooting Guide, Page 10.

Draining Pump

1. Pump down water level below all inlets to the pool.

To avoid dangerous or fatal electrical shock hazard, turn OFF power to

motor before draining pump.

2. To prevent pump from freezing, drain the pump body through the drain

plug (Key No. 12, Page 11). Clean pump thoroughly.

3. Cap inlet piping after draining to keep water out of the pipes.

4. Be sure motor is kept dry and covered.

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.

Hazardous suction.

Can trap hair or

body parts, causing

severe injury

or death.

Do not block

suction.

Hazardous voltage.

Can shock, burn,

or cause death.

Disconnect power

before working

on pump or motor.

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.

PUMP SERVICE

Pump should only be serviced by qualified personnel.

Be sure to prime pump (Page 7) before starting.

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 shaft seal is worn or damaged, repair as follows:

Removal of Old Seal

1. Remove drain plug (Key No. 12 in exploded view, Page 11) and drain

pump. Disconnect bonding wire from bonding lug on motor (Key No. 3,

Page 11).

2. Remove four capscrews (Key Nos. 4 and 14, Page 11) and remove motor,

seal plate, and impeller as a unit. Do not disturb pump body.

3. Remove canopy from back of motor and hold motor shaft with a 7/16”

wrench on the shaft flats. Unscrew impeller off of shaft.

Capacitor voltage can be dangerous. Before proceeding, short

the capacitor terminals together with a screwdriver that has an insulated

handle.

Being careful not to touch capacitor terminals, loosen capacitor clamp and

move capacitor to one side to reach shaft end.

4. After unscrewing impeller, carefully remove rotating part of seal by prying

up on sealing washer, using two screwdrivers (see Figure 4A). Use care not

to scratch motor shaft.

5. Remove seal plate from motor and place on flat surface, face down. Use a

screwdriver to push ceramic seat out from seal cavity (see Figure 4B).

Installation of Floating Seat (Figure 4C)

1. Clean polished surface of floating seat with clean cloth.

2. Turn seal plate over so seal cavity is up; clean cavity thoroughly.

3. Lubricate outside rubber surface of ceramic seat with soapy water and

press firmly into seal cavity with finger pressure. If seat will not locate prop-

erly in this manner, place cardboard washer over polished face of seat and

press into seal cavity using a 3/4” socket or 3/4” piece of standard pipe.

4. Dispose of cardboard washer. Be sure polished surface of seat is free of dirt

and has not been damaged by insertion. Remove excess soapy water.

Installation of Rotating Part of Seal Unit (Figure 4D)

1. Reinstall seal plate using extreme caution not to hit ceramic portion of seal

on motor shaft.

2. Inspect shaft to make sure that it is clean.

3. Clean face of sealing washer with clean cloth.

4. Lubricate inside diameter and outer face of rubber drive ring with soapy

water and slide assembly onto motor shaft (sealing face first) until rubber

drive ring hits shaft shoulder.

5. Screw impeller on to shaft until impeller hub hits shaft shoulder. This will

automatically locate seal in place and move the sealing washer face up

against seat facing.

6. Reinstall gasket on seal plate. Slide motor/seal plate/impeller into pump

body and reinstall capscrews.

7. Reinstall bonding wire on bonding lug on motor.

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!

FAILURE TO PUMP; REDUCED CAPACITY OR DISCHARGE PRESSURE

Suction leaks/lost prime:

1. Pump must be primed; make sure that pump volute is full of water. See

priming instructions, Page 7.

2. Make sure there are no leaks in suction piping.

3. Make sure suction pipe inlet is well below the water level to prevent

pump from sucking air.

4. Suction lift of 15 to 25 feet (4.5 to 7.5 meters) will reduce performance.

Suction lift of more than 25 feet (7.5 meters) will prevent pumping and

cause pump to lose prime. In either case, move pump closure (vertically)

to water source. Make sure suction pipe is large enough.

Clogged pipe/impeller, worn impeller:

5. Make sure impeller is not clogged (follow instructions under “Removal of

Old Seal”, Page 9; check impeller for clogging; follow instructions under

“Installation of Rotating Part of Seal Unit”, Page 9, for reassembly).

6. Impeller may be worn. If so, order replacement parts from Repair Parts

List, Page 11.

7. Pump may be trying to push too high a column of water. If so, a “higher

head” pump is needed.

Electrical:

8. Pump may be running too slowly; check voltage at motor terminals and at

meter while pump is running. If low, see wiring instructions or consult

power company. Check for loose connections.

9. Pump may be too hot.

A. Check line voltage; if less than 90% or more than 110% of rated volt-

age consult a licensed electrician.

B. Increase ventilation.

C. Reduce ambient temperature.

D. Tighten any loose connections.

MECHANICAL TROUBLES AND NOISE

1. If suction and discharge piping are not adequately supported, pump

assembly will be strained. See “Installation”, Page 3.

2. Do not mount pump on a wooden platform! Securely mount on concrete

platform for quietest performance.
