Disconnect power at its source, lock out the power, and place a tag on the dedicated GFCI circuit breaker indicating the power is to remain off. A. Close suction discharge valves to isolate pump. B. Drain the basket housing and pump housing through the drain plugs. C. 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 for purging the pump, filter, or piping. Allowing pump to freeze will damage pump and void warranty! Use only non-toxic anti-freeze. Do not use automotive antifreeze. It is highly toxic and may damage plastic components in the system. PUMP SERVICE If the pump mechanical seal (reference numbers 8a and 8b on page 9) starts leaking replace it immediately to avoid damage to motor or other components. Pump should only be serviced by qualifi ed personnel. Use only AquaPRO ® Systems factory parts. BEFORE REMOVING CLAMP ON BASKET HOUSING: • STOP PUMP ELECTRICALLY: Disconnect the power at its source, lock out the power, and place a tage on the dedicated GFCI circuit breaker indicating the power is to remain OFF. • CLOSE GATE VALVES in suction and discharge pipes. • RELEASE ALL PRESSURE from pump and piping system. Refer to the fi lter manual for method. • NEVER tighten or loosen clamp while pump is operating! To avoid dangerous or fatal electrical shock hazard, turn OFF and lock out power to motor before working on pump or motor. REPAIR DISASSEMBLY 1. Disconnect power at its source, lock out the power, and place a tag on the dedicated GFCI circuit breaker indicating the power is to remain OFF. 2. Drain pump by removing drain plugs on bottom of pump body and basket body. 3. Disconnect electrical connections at motor. 4. Remove six knobs holding seal plate to pump body. 5. Slide motor/seal plate assembly out of the back of the pump. 6. Remove three screws holding diffuser to seal plate. 7. Remove motor shaft cover on rear of motor (see Figure 4). Use a wrench or a large screw driver to stop motor shaft rotation. Figure 4 8. Remove screw from center of impeller. The threads are reversed. Turn clockwise to loosen screw (Figure 5). Impeller screw To loosen, turn screw clockwise (#4 on p.11) Figure 5 9. Then grasp impeller and rotate counterclockwise to remove impeller from shaft. 10. Pull mechanical seal rotating assembly from motor shaft. 6 Mechanical Seal Rotating Assembly (# 8b on p.11) Figure 6 11. With a screw driver carefully pry old stationary seat from seal plate (see Figure 7). DO NOT SCRATCH SEAL BORE. Mechanical Seal Stationary (#8a on p. 11) Figure 7 12. If shaft is corroded or dirty motor will need to be removed from seal plate so that the shaft can be effectively cleaned. 13. If necessary use a 9/16 socket with a 6 inch extension to remove four screws holding motor to seal plate. If seal has been leaking for a long time the motor bearing may be compromised, if excessive corrosion or shaft end play can be detected motor will need to be replaced. REASSEMBLY 1. Obtain a new mechanical seal rotating assembly and seat (reference numbers 8a and 8b on page 11). Seal parts must be replaced as a set. Do not mix old and new parts. Lubricate seal stationary o-ring with a very small amount of dish soap. Do not allow soap, dirt, grease, or any contaminate on the polished seal face (see Figure 8). Stationary o-ring Polished seal face, keep clean during assembly Figure 8 Anillo de desgaste Notese: el reborde en el anillo de desgaste de fl otacion apunta hacia afuera. Figura 9 5. Reemplace el anillo en O del difusor (referencia de la pieza N. 5 en la pagina 23) si esta danado. Limpie la ranura del anillo en O antes de instalar un nuevo anillo en O. 6. Instale el difusor con 3 tornillos, cubra el anillo en O con una pequena cantidad de jabon para vajilla para facilitar el ensamblaje dentro del cuerpo de la bomba. 7. Cambie el anillo en O de la placa de sellado principal por uno nuevo. Limpie la superficie antes de instalar. 8. Deslice el ensamble giratorio de regreso en la caja de la bomba. 9. Apriete las seis perillas en un patron escalonad...
