SERIES “ABG”
SWIMMING POOL PUMP
INSTALLATION
For ease of pump/motor removal, install pipe unions on the suction and dis¬charge pipes close to pump.
Pump mount must:
Be located away from corrosive or flammable liquids.
Have enough ventilation to maintain air temperature at less than the maxi-mum ambient temperature rating (Max. Amb.) listed on the motor model plate. If this pump is installed in an enclosure/pump house, the enclosure must have adequate ventilation and air circulation to keep the temperature in the enclosure at or below the motor’s rated ambient temperature whenev¬er the pump is running.
Be solid - Level - Rigid - Vibration free. (To reduce vibration and pipe stress, bolt pump to mount.)
Allow pump suction inlet height to be at or below water level in pool. 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 flooding.
Allow adequate access for servicing pump and piping.
NOTICE: Use Teflon tape or Plasto-Joint Stik1 for making all threaded con¬nections 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. 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 trap. Use care when using teflon tape as friction is reduced consider-ably; do not overtighten connections or damage may occur.
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:
To avoid strains on the pump, support both suction and discharge pipes or hoses independently. Place these supports near the pump.
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.
Union available for pump discharge port (Sta-Rite part number WC1 98-1 05). 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 union.
4. Bond pipe to union 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.
NOTICE: Determine circuit breaker rating from Table I. Determine correct outlet required from illustration below.
“ABG” Models with -2A2, -2A4,
and -3A4 suffix use 15-amp
straight outlet.
“ABG” Models with -2A1 suffix use 20-amp twist-lock outlet.

ELECTRICAL
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 electri¬cal 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.
Plug cord of pump directly into a GFCI protected receptacle.
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 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.
Wiring:
Do not alter cord or plug on cord-connected units. Plug in to a GFCI pro¬tected, grounded outlet only. If plug and outlet do not match, consult a licensed electrician.
Table I, gives correct 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 circuit breaker sizes. (If unsure how to do this or if this is confusing, consult a licensed electrician.) Use the load cir¬cuit 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 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.
Values given in table below are for PUMP MOTOR ONLY. If additional accessories are installed on pump motor circuit (heater, blower, etc.), include their amperage 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.
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.
Fire and burn hazard. Modern motors run at high temperatures. To reduce the risk of fire, do not allow leaves, debris, or foreign matter to collect around the pump motor. To avoid burns when handling the motor, let it cool for 20 minutes before trying to work on it. An automatic internal cutoff switch protects the motor from heat damage during operation.
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. To do so may flood area causing dam-age to equipment and water damage to surrounding area.
Priming Pump:
Open valves before starting system.
Release all pressure from filter, pump, and piping system; see the filter own¬er’s manual.
In a flooded suction system (water source higher than pump), pump will prime itself when suction and discharge valves are opened.
Pool 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 pool water “balanced”. Maintain the water pH between 7.2 and 7.6.
Do not use or allow the use of the 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.
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 vol¬ume blower when air purging the pump, filter, or piping.
To prevent damage to components from fumes, store chemicals away from pump. If possible, store chemicals in another room.
NOTICE: Drain pump! Allowing pump to freeze will damage pump and void warranty!
NOTICE: Do not use anti-freeze solutions (except propylene glycol) in your pool system. Propylene glycol is non-toxic and will not damage plastic sys¬tem components; other anti-freezes are highly toxic and may damage plastic components in the system. Propylene glycol is widely used as antifreeze in recreational vehicles.
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 or wrap pump with plastic.
For outdoor/unprotected installations:
1. Pump down water level below all inlets to pool.
2. Enclose entire system in a weatherproof enclosure.
3. To avoid condensation/corrosion damage, allow ventilation; do not wrap system in plastic.
4. Use a 40% propylene glycol/60% water solution to protect pump to - 50°F.
5. Follow pool manufacturer’s directions for storage of pool.
Draining Pump:
To avoid dangerous or fatal electrical shock hazard, turn OFF power to motor before draining pump.
1. Close all valves on suction and return piping.
2. Remove drain plug in bottom of trap body.
3. Drain all piping and storage tanks exposed to freezing temperatures.
4. Be sure no airlocks are holding water in the system.
5. To prevent pump from freezing, remove trap cover and drain the tank body through the drain plug (Key No. 12, Page 10 and Key No. 1 8, Page 11). Clean pump thoroughly. Replace trap cover.
6. Before restarting, replace all plugs and make sure all pipe connections are tightly sealed.
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 shut
down 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 6.
10. Refill pool to proper water level.
PUMP SERVICE
Pump should only be serviced by qualified personnel. Be sure to prime pump (Page 7) before restarting.
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.
To avoid dangerous or fatal electrical shock hazard, turn OFF power to motor before working on pump or motor.
No lubrication or regular maintenance is needed beyond reasonable care and periodic cleaning.
If shaft seal is worn or damaged, repair as follows:
Removing Old Seal:
1. Disconnect power to pump motor.
2. Drain pump; disconnect unions to allow access to pump.
3. Remove four bolts holding trap body to seal plate; remove trap body.
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 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 3). Do not damage impeller surface where drive ring seats and seals.
6. Carefully remove four motor throughbolts from seal plate (Figure 4); remove seal plate and use a screwdriver to tap ceramic seat out from the rear (Figure 5). 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 water; press into cavity firmly and squarely with finger pressure (Figure 6).
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).
5. Screw impeller onto shaft until it seats against shaft shoulder. Work slinger over end of impeller sleeve so it rides on sleeve (Figure 7).
6. Install wear ring on back of volute. NOTICE: Teeth on wear ring interlock with ribs on trap body.
7. Remount trap body.
8. Reconnect unions; tighten hand tight only.
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 and trap are full of water. See priming instructions, Page 6.
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 1 to 2 feet (.3-.6M) will reduce per¬formance. Suction lift of more than 2 feet (.6M) will prevent pumping and cause pump to lose prime. In either case, move pump closer (vertically) to water source. Make sure suction pipe is large enough.
Clogged pipe/trap/impeller, worn impeller:
1. Make sure suction trap is not clogged; if it is, clean trap and strainer.
2. Make sure impeller is not clogged (follow instruc¬tions under “Removing Old Seal”, Page 8; check impeller for clogging; follow instructions under “Installing New Seal”, above, for reassembly).
3. Impeller and diffuser may be worn. If so, order replacement parts from
Repair Parts List, Pages 10 and 11.
Inadequate Circulation or Jet Action:
1. Check for blocked fittings. Blocked fittings will cause poor flow and poor jet action.
2. Check trap basket; if plugged, turn pump off and clean basket. Check and clean skimmer basket.
3. Check that gate valves are fully open.
4. Suction/discharge piping is too small.
5. Check and clean pool filter.
6. Check for clogged pipe/trap/impeller, Page 8.
7. 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 manufac¬turer’s instructions.
3. Be sure no other lights and appliances are on cir¬cuit.
4. Consult dealer/installer or service representative.
5. Voltage too high or too low. See “Voltage”, Page 5. Electrical:
1. Pump may be running too slowly; check voltage at motor terminals and at meter while pump is run¬ning. If low, see wiring instructions or consult power company. Check for loose connections.
2. Pump may be too hot.
A. Check line voltage; if less than 90% or more than 110% of rated voltage consult a licensed electrician.
B. Increase ventilation.
C. Reduce ambient temperature.
D.Tighten any loose wiring connections.
3. Motor internal termal overload protector is open. Motor runs too hot. Turn power to motor off. Check for proper voltage. Check for proper impeller or impeller rubbing.
4. Consult dealer/installer or service representative. 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.
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 service instructions on Page 8 for reassembly.
5. Cavitation.
Improve suction conditions. Increase pipe size.
Decrease number of fittings. Increase discharge pressure.
Reducer flow by throttling discharge gate valve. |
