1. Connect ground wire first. Connect the ground first, then to green grounding terminal provided under motor canopy (see Figure 5) identified as GRD. Make ground connection to this terminal. Do not connect motor to electrical power supply until unit is permanently grounded; otherwise serious or fatal electrical shock hazard may be caused. 2. For best ground connection, connect to a grounded lead in the service panel or to a metal underground water pipe or well casing at least 10 ft. long. If plastic pipe or insulated fittings are used, run ground wire directly to the metal well casing or use ground electrode furnished by the power company.

Can shock, burn or cause death. Disconnect power to pump before servicing. Tools required: 1. 7/16” open end wrench (2 required). 2. Flat blade screwdriver with insulated handle. 3. Work bench with vise recommended. 4. Pliers or similar tool. 5. Pipe wrench. Impeller Stack Replacement (See Figure 7) Remove pump from service and mount vertically in vise (if available) motor side down. Clamp motor at center. It may be desirable to wrap motor with a shop rag to protect outside surface. Proceed as follows: 1. Attach pipe wrench to flats on discharge connection and turn clockwise to remove (left hand threads). 2. Remove screws holding motor canopy and remove canopy. Pull canopy straight off as shown. 1 Remove with clockwise Discharge rotation. Connection Capacitor voltage may be hazardous. To discharge capacitor, hold insulated handle screwdriver by the handle and short capacitor terminals together. Do not touch metal screwdriver blade or capacitor terminals. 3. Unscrew capacitor clamp and remove capacitor. Do not disconnect capacitor wires. Slide 7/16” open end wrench in behind spring loaded centrifugal switch as shown. Place on motor shaft flats to hold shaft stationary. 4. With one 7/16” wrench in place on motor shaft, place second wrench on shaft hex at pump end and unscrew impeller stack by turning counter-clockwise. 5. Once loose from motor shaft, hold shaft by snap ring using a pliers or similar tool, and pull stack from shell. You may have to apply a back and forth motion to break stack loose from shell. To assemble with replacement impeller stack, keep pump in the vertical position, motor down, and reverse instructions 1 through 5. Assembly hints: A. Apply a soapy water solution to suction and dischage O-Rings to ease seating of shell. B. Make sure mechanical shaft seal spring is in proper position on motor shaft. 4 Disconnect from power source.

For parts or assistance, call Flotec Customer Service at 1-800-365-6832 Maintenance 9 For parts or assistance, call Flotec Customer Service at 1-800-365-6832 Mechanical Seal Replacement (refer to Figures 7 and 8) This procedure is best completed with the pump held in a vertical position, motor down. First complete “Disassembly” instructions 1 through 5 under “Impeller Stack Replacement.” (see Figure 7). 6. Remove 4 capscrews holding pump body to motor. Pump handle will come off with top capscrews. 7. Unscrew pump shell from pump body, turning clockwise (left hand threads). 8. Remove mechanical shaft seal spring and rotating half from motor shaft. Use care not to scratch motor shaft when removing rotating half. 9. Remove pump body from motor and place on flat surface, face down. Again, use care not to scratch motor shaft. 10.Use a screwdriver to push ceramic seat out from seal cavity as shown. 11. Installation of ceramic seat: A. Turn pump body over so seal cavity is up; clean cavity thoroughly. B. Clean polished surface of ceramic seat with a clean cloth. C. Lubricate outside rubber surface of seat with soapy water. Place cardboard washer over polished face of seat and press into seal cavity using a 3/4” socket or a piece of 3/4” standard pipe. D. Be sure polished surface of seat is free of dirt and has not been damaged by insertion. Remove excess soapy water. Dispose of cardboard washer. 12.Installation of rotating half and spring: A. Reinstall pump body on motor using extreme caution not to hit ceramic portion of seal on motor shaft. Reattach pump body to motor using capscrews. Be sure to reinstall pump handle at this time. B. Inspect shaft to make sure that it is clean. C. Clean face of rotating half of seal with a clean cloth. D. Lubricat...
