Discharge Port to Filter or Pool Strainer Basket Cover Bonding Lug Suction Port from Pool or Vacuum Filters IMPORTANT SAFETY INSTRUCTIONS Always follow basic safety precautions with this equipment, including the following. Pump may be bolted to level foundation or mounting bracket. To reduce the risk of injury, do not permit children to use this product unless they are closely supervised at all times. Figure 2 NOTICE: Port threads are: Internal - 2" NPT for direct connection to pipe. External - 3-1/4" Buttress. Fits Sta-Rite U11-200P Union Collar for quick disconnect pipe connection. 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. See Page 13 for Union Kits. Pump mount must: Be located away from corrosive or flammable liquids. Have enough ventilation to maintain air temperature at less than the maximum 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 whenever the pump is running. Be solid - Level - Rigid - Vibration free. (To reduce vibration and pipe stress, bolt pump to mount.) SAVE THESE INSTRUCTIONS 4 POOL PUMP SUCTION REQUIREMENTS Allow pump suction inlet height to be as close to water level as possible. Pump will not lift water more than 10' (3m). 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. 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. NOTICE: When connecting threaded pipe directly to pump, use Teflon® tape or Plasto-Joint Stik® to seal connections. Do not use pipe dope; pipe dope causes cracking in some plastics and may damage components in piping system. When connecting pipe to pump with union half, use Teflon® tape or Plasto-Joint Stik® between pipe and union adapter. Union collar to pump should be assembled dry and hand-tight. NOTICE: Pump suction and discharge connections have molded in thread stops. DO NOT try to screw pipe in beyond these stops. Hazardous suction. Can trap hair or body parts, causing severe injury or death. Pump suction is hazardous and can trap and drown or disembowel 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 Do not block suction. 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 Page 6 for outlet cover certification requirements. All suction outlets must have correctly installed, screw-fastened covers in place. Teflon® Taping Instructions: Suction Outlets Per Pump (Figure 3, Page 6) 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! Provide at least two hydraulically balanced main drains, with covers, as suction outlets for each circulating pump suction line. The centers of the main drains (suction outlets) on any one suction line must be at least three feet apart. 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 – see Figure 3, Page 6). However, if two main drains run into a single suction line, the single suction line may be equipped with a valve which will shut off both main drains from the pump (see Figure 3). Piping: Use at least 2" (51mm) pipe. 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. 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. More than one pump can be connected to a single suction line as long as the requirements above are met. 5 ELECTRICAL Water Velocity The maximum water velocity through the suction fitting or cover for any suction outlet must not exceed 1.5 feet per second unless the outlet complies with the latest ANSI/ASME Specification for Suction Fittings For Use in Swimming Pools, Spas, Hot Tubs, and Whirlpool Bathtub Applications. In any case, do not exceed the suction fitting’s maximum 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 second or less even if one main drain (suction outlet) is completely blocked. The flow through the remaining main drain(s) must comply with the latest ANSI/ASME Specification for Suction Fittings For Use in Swimming Pools, Spas, Hot Tubs, and Whirlpool Bathtub Applications. 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. Hazardous voltage. Can shock, burn, or cause death. 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. Disconnect power before working on pump or motor. Testing and Certification Suction outlet covers must have been tested by a nationally recognized testing laboratory and found to comply with the latest ANSI/ASME Specifications for Suction Fittings For Use in Swimming Pools, Spas, Hot Tubs, and Whirlpool Bathtub Applications. 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. Fittings: Voltage Fittings restrict flow; for best efficiency use fewest possible fittings (but at least two suction outlets). 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. 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. At Least 3 Feet IAPMO Certified Anti-entrapment Cover or Suction Fitting, screw-fastened to Main Drain Sump No valves between Tee and Main Drains Suction Outlet (Main Drain) IAPMO Certified Anti-entrapment Cover or Suction Fitting, screw-fastened to Main Drain Sump Suction Outlet (Main Drain) Pump Valves OK between pump and Tee 2762 0197 Figure 3 – Recommended pump suction layout. 6 Grounding/Bonding 1. Turn off power. 2. Remove the motor end cover. 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 4); 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 4) to reinforcing rod or mesh. To Wire a Single Speed, Single Voltage Motor There are two terminals labeled L1 and L2. Attach the power leads to these terminals. Either wire may attach to either terminal. To Wire a Dual-Voltage Motor Dual voltage motors have a plug to change from 230 volts (factory setting) to 115 volts. 1. If you have 230 volts motor supply voltage, confirm that the plug is set for 230 volts. The arrow on the plug will point to the 230 volt position. Note that plug only connects with one prong in this position. 2. If you have 115 volt supply, pull the plug straight up and place it on the two brass prongs as shown. Bonding Lug 230V 115V Green Ground Screw A L2 L1 Figure 4 – Typical ground screw and bonding lug locations. 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 NOTICE: 3 phase models require magnetic motor starters and external overload protection. If in doubt about the procedure, consult a licensed electrician. Pump must be permanently connected to circuit. Table I, Page 8, give 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 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.

NOTICE: Tighten trap cover handle ring by hand only (no wrenches)! See Figure 1, Page 4. Pump should prime now. Priming time will depend on vertical length of suction lift and horizontal length of suction piping. If pump does not prime, make sure that all valves are open, suction pipe end is under water, pump is not trying to lift water more than 10' (3m), and that there are no leaks in suction pipe. See Troubleshooting Guide, Page 12. NOTICE: 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. If pump is being pressure tested, be sure pressure has been released before removing trap cover. 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. Routine Maintenance The only routine maintenance needed is inspection/cleaning of trap basket. Debris or trash that collects in basket will choke off water flow through the pump. Follow instructions below to clean trap: 1. Stop pump, close valves in suction and discharge, and release all pressure from system before proceeding. 2. Remove trap cover handle ring (turn counterclockwise). If necessary, tap handles gently with a rubber mallet. 3. Remove strainer basket and clean. Be sure all holes in basket are clear, flush basket with water and replace in trap with large opening at pipe connection port (between ribs provided). If basket is replaced backwards cover will not fit on trap body. 4. Clean and inspect lid O-Ring; reinstall on trap groove. 5. Clean O-Ring groove on trap body and replace cover and handle ring. To help keep cover from sticking, tighten hand tight only. 6. Prime pump (see priming instructions). Fire and burn hazard. Modern motors run at high temperatures. To reduce Hazardous suction.

To avoid burns when Do not block handling the motor, let it cool suction. for 20 minutes before trying to work on it. An automatic internal cutoff switch protects the motor from heat damage during operation. NOTICE: Maximum ambient temperature for motor operation must not exceed maximum ambient temperature on motor nameplate. Storage/Winterizing Priming Pump 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, “RV antifreeze”, 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 below). Keep motor dry and covered during storage. To avoid condensation/corrosion problems, do not cover pump with plastic. Release all pressure from filter, pump, and piping system; see the 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 is not in a flooded suction system, unscrew and remove trap cover; fill trap and pump with water. Clean and inspect O-Ring; reinstall on trap groove. Do not lubricate the trap cover O-Ring. The original equipment O-Ring contains a permanent internal lubricant. NOTICE: If you replace the O-Ring with a non-internally lubricated O-Ring, you may need to apply a silicone based lubricant. 9 For outdoor/unprotected installations: Startup For Winterized Equipment 1. Enclose entire system in a weatherproof enclosure. 1. Remove any temporary weather protection placed around system for shutdown. 2. To avoid condensation/corrosion damage, allow ventilation; do not wrap system in plastic. 2. Follow filter manufacturer’s instructions for reactivation of the filter. 3. Use a 40% propylene glycol/60% water solution to protect pump to -50°F (-46°C). 3. Inspect all electrical wiring for damage or deterioration over the shutdown period. Have a qualified serviceman repair wiring as needed. Draining Pump 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. 4. Inspect and tighten all watertight connections. 1. Pump down water level below all inlets to the pool. 8. Close all drain valves and replace all drain plugs in piping system. 5. Open all valves in suction and return piping. 6. Remove any winterizing plugs in piping system. 7. Drain all antifreeze from system. To avoid dangerous or fatal electrical shock hazard, turn OFF power to motor before draining pump. Hazardous voltage. Can shock, burn, or cause death. Disconnect power before working on pump or motor. 9. Prime pump according to instructions on Page 9. PUMP SERVICE 2. Remove trap cover handle ring (turn counterclockwise). If necessary, tap handles gently with a rubber mallet. Low pressure air can be used to remove remaining water from the piping. Pump should only be serviced by qualified personnel. For best results, use only genuine Sta-Rite factory parts. Be sure to prime pump (Page 9) 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. 3. Cap inlet piping after draining to keep water out of the pipes. 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 of strainer basket. 4. To prevent pump from freezing, remove trap cover and drain the tank body through the two drain plugs provided. A. Gravity drain system as far as possible. B. Protect areas which retain water with non-toxic propylene glycol antifreeze (“RV” antifreeze). 5. Clean pump thoroughly; replace trap cover. NOTICE: Tighten trap cover by hand only (no wrenches)! If pump is not anchored, use caution to not break attached piping! Hazardous voltage. Can shock, burn, or cause death. 6. Be sure motor is kept dry and covered. Disconnect power before working on pump or motor. 10 Pump Reassembly/Installing New Seal If shaft seal is worn or damaged, repair as follows: 1. Ceramic seat must be clean and free of dirt, grease, dust, etc. Wet outer edge with small amount of liquid detergent; press ceramic seat into seal plate cavity firmly and squarely with finger pressure (Figure 7). Pump Dissasembly/Removing Old Seal Disconnect power to pump motor. Be sure valves on suction and return piping are closed before starting work. Release all pressure by opening all vents before starting work. Polished surface 1. Drain pump by removing drain plugs on bottom of pump body and trap body. Rubber surface 2. Be sure there is no pressure in trap body; remove cover (unscrew by turning counterclockwise). 3. Remove 6 nuts, lockwashers and flat washers holding seal plate to pump body. Pull seal plate and motor away from pump body. (You may have to CAREFULLY use a screwdriver to separate body from seal plate.) Figure 7 4. Remove seven screws and washers holding diffuser to seal plate. Remove diffuser. 2. If ceramic seat will not locate properly, remove it, place face up on bench and reclean cavity. Ceramic seat should now locate. 5. Remove motor canopy. Being careful not to touch capacitor terminals, loosen capacitor clamp and move capacitor to one side. 3.
