Before pressure testing, make the following safety checks:
Check all clamps, bolts, lids, and system accessories before testing.
Release all air in system before testing.
Tighten Sta-Rite trap lids to 30 ft. lbs. (4.1 kg-m) torque for testing.
Water pressure for test must be less than 25 PSI (7.5 kg/cm
2
).
Water Temperature for test must be less than 100oF. (38oC).
Limit test to 24 hours. After test, visually check system to be sure it is ready for operation. Remove trap lid and retighten hand tight only.
NOTICE: These parameters apply to Sta-Rite equipment only. For non-Sta-Rite equipment, consult manufacturer.
Motor normally operates at high temperature and will be too hot to touch. It is protected from heat damage during operation by an auto­matic internal cutoff switch. Before handling pump or motor, stop motor and allow it to cool for 20 minutes.
IMPORTANT SAFETY INSTRUCTIONS
Always follow basic safety pre­cautions with this equipment, including 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 constructed 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 disassembled for storage and reassembled to its original integrity.
SAVE THESE INSTRUCTIONS

NOTICE: This pump is designed to power automatic swimming pool cleaners or other systems requiring high pressure at relatively low flow rates. Operating the pump with open discharge or without flow restric­tion could overload the pump motor. Operate the pump only while con­nected to the system in which it is designed to operate. When installed for automatic time clock operation on a swimming pool cleaner system, be sure that clock is set so that the cleaner booster pump comes on only when the main circulation system for the pool is operating. Failure to coordinate the “on” cycles could provide insufficient flow to the cleaner booster pump, resulting in failure of the booster pump.
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 to be as close to pool return line as possible. Allow use of short, direct suction pipe from tee on return line (See Fig. 1). 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 Stik
1
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
additional layers of tape and remake the connection.
NOTICE: Support all piping connected with pump!
Piping:
Never use a suction pipe smaller than pump suction connection.
Use 3/4” I.D. discharge pipe up to 50’ length. Use 1” pipe if run is over 50’.
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.
To avoid airlocking, slope suction pipe slightly upward toward the pump. NOTICE: To prevent flooding when removing pump for service, all flood-
ed 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.

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 nameplate rated voltage or motor may overheat, causing overload tripping 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.
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 3A); use size and type wire required by code. Connect motor ground terminal to electrical service ground.
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 (1.5m) of the inside walls of swimming pool, spa, or hot tub.
Wiring (See Figure 3B):
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 short­circuit to ground and disconnect power before it becomes dangerous to pool users. For size of GFCI required and test procedures for GFCI, see manufactur­er’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.

OPERATION
NEVER run pump dry! Running pump dry may damage seals, causing leakage and flooding! Fill pump with water before starting motor.
Before working on pump:
1. STOP PUMP before proceeding.
2. CLOSE GATE VALVES in suction and discharge pipes.
3. RELEASE ALL PRESSURE from pump and piping system.
4. NEVER tighten or loosen clamp while pump is operating!
Priming Pump:
Release all air from filter and piping system: see filter owner’s manual. Pump will prime itself when suction and discharge valves are opened, and main pool pump is running. If pump does not prime, make sure that all valves are open, main pool pump is running, and that there are no leaks in suction pipe. See Troubleshooting Guide, Page 11.
Storage/Winterizing:
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 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, Page 7). Keep motor dry and covered during storage. To avoid condensation/corrosion problems, do not cover pump with plastic. For outdoor/unprotected installations:
1. Enclose entire system in a weatherproof enclosure.
2. To avoid condensation/corrosion damage, allow ventilation; do not
wrap system in plastic.
3. Use a 40% propylene glycol/60% water solution to protect pump to - 50°F.
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. Use low pressure air to blow accumulated water from the piping system.
3. To prevent pump from freezing, remove priming plug and drain the pump body through the drain plug (Key No. 18, Page 10). Clean pump thor­oughly; replace priming plug.
4. Be sure motor is kept dry and covered.
Startup For Winterized Equipment:
1. Remove any temporary weather protection placed around system for shut­down.
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 above.

PUMP SERVICE
Pump should only be serviced by qualified personnel. Be sure to prime pump (Page 7) and start main pool pump 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.
4. NEVER tighten or loosen clamp while pump is operating!
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. If shaft seal is worn or damaged, repair as follows:
Pump Disassembly/Removing Old Seal:
Disconnect power to pump motor.
Be sure gate valves on suction and return piping are closed before starting
work. Release all pressure before starting work.
1. Drain pump by removing drain plugs on bottom of pump body and trap body.
2. Remove clamp holding pump halves together (Figure 4).
3. Remove pump base mounting bolts. Motor and seal plate assembly can now be pulled away from pump body.
4. Remove five screws and washers holding diffuser to seal plate. Remove diffuser (Figure 5).
5. If impeller must be replaced, loosen two machine screws and remove motor canopy (see Figure 6).
6. Capacitor voltage may be hazardous. To discharge capaci- tor, hold insulated handle screwdriver BY THE HANDLE and short capaci­tor terminals together (see Figure 6). Do not touch metal screwdriver blade or capacitor terminals. If in doubt, consult a qualified electrician.
7. Unscrew capacitor clamp and remove capacitor. Do not disconnect capacitor wires to motor.
8. Slide 7/16” open end wrench in behind spring loaded switch on motor end of shaft; hold motor shaft with wrench on shaft flats and unscrew impeller by turning counterclockwise when looking into eye of impeller.
9. Unscrew four nuts holding pump back half to motor. Remove rotating half of seal by placing two screwdrivers under back half of pump body and carefully prying up (Figure 7, Page 9). Back half of pump body will slide off shaft, bringing seal with it. NOTICE: Be sure you do not scratch or mar shaft; if shaft is marred, it must be dressed smooth with fine emery or crocus cloth before installing new seal. DO NOT reduce shaft diameter!
10. Place pump body face down on flat surface and tap out stationary half of
seal (see Figure 8, Page 9).

Installing New Seal/Pump Reassembly:
1. Clean seal cavity in seal plate.
2. Wet outer edge of O-Ring on ceramic seat with liquid soap. Be sparing!
3. Put cardboard washer over seal face. With thumb pressure, press ceram­ic seal half firmly and squarely into seal cavity in seal plate (see Fig. 9). Polished face of ceramic seat is up. If seal will not seat correctly, remove, placing seal face up on bench. Reclean cavity. Seal should now seat correctly.
4. If seal does not seat correctly after recleaning cavity, place a cardboard washer over polished seal face and carefully press into place using piece of standard 3/4” pipe as a press. NOTICE: Be sure you do not scratch seal face.
5. Dispose of cardboard washer and recheck seal face to be sure it is free of dirt, foreign particles, scratches and grease.
6. Inspect shaft to be sure it is free of nicks and scratches.
7. Reassemble pump body half to motor flange. BE SURE it is right side up.
8. Apply liquid soap sparingly (one drop is sufficient) to inside diameter of rotating seal member.
9. Slide rotating seal member (carbon face first) onto shaft until rubber drive ring hits shaft shoulder.
NOTICE: Be sure not to nick or scratch carbon face of seal when pass-
ing it over threaded shaft end or shaft shoulder. The carbon surface must remain clean or short seal life will result.
10. Hold motor shaft with 7/16” open end wrench on shaft flats and screw impeller onto shaft. Tightening impeller will automatically locate seal in correct position.
11. Remount diffuser on pump body half with five screws.
Pump Reassembly:
1. Clean O-Ring and O-Ring groove.
2. Put O-Ring in groove on face of seal plate; put pump halves together
(see Figure 10).
3. BE SURE inside of clamp is clean. Place clamp on pump halves; snug up.
Alternately tighten screw and tap clamp with mallet to seat O-Ring (see Figure 11).
4. Replace base mounting bolts.
5. Replace drain plug.
6. Prime pump according to instructions. See “Operation”, Page 7.
7. Check for leaks.
