6 DO NOT run the pump dry. If the pump is run dry, the mechanical seal will be damaged and the pump will start leaking. If this occurs, the damaged seal must be replaced. ALWAYS maintain proper water level. If the water level falls below the suction port, the pump will draw air through the suction port, losing the prime and causing the pump to run dry, resulting in a damaged seal. Continued operation in this manner could cause a loss of pressure, resulting in damage to the pump case, impeller and seal and may cause property damage and personal injury. Pump Reassembly 1. If replacing the shaft seal, follow the instructions provided with the replacement seal. If not, continue to the next step. 2. Remount the seal plate to the motor. 3. Grease the motor shaft threads. 4. Clean both halves of the shaft seal with soapy water and a clean cloth. The white ceramic half is seated in the seal plate. 5. Place the spring half of the shaft seal onto the motor shaft. 6. Using a 1/4" hex-key wrench, hold the motor shaft in place at the rear of the motor. This prevents the motor shaft from spinning while reinstalling the impeller and impeller screw. 7. Reinstall the impeller onto the motor shaft clockwise. Hand tighten only! 8. Ensure the impeller screw washer is in place and thread the impeller screw into the motor shaft counter-clockwise. 9. Reinstall the diffuser, ensuring the line molded onto the diffuser is aligned with the line molded onto the seal plate. 10. Grease the diffuser quad ring and seal plate O-ring prior to reassembly. 11. Grease the bolt threads and assemble the motor/ hydraulics sub-assembly to the strainer pot using. Do not fully tighten any of the bolts until all four bolts are in place and finger tightened. 12. When ready to restart the pump, continue to Priming the Pump. IMPELLER SCREW IMPELLER SCREW WASHER Priming the Pump If the pump is installed below the water level of the pool, close return and suction lines prior to opening the pump's strainer pot. Make sure to re-open valves prior to operating. The pump strainer pot must be filled with water before the pump is initially started. To prime the pump: 1. Gently tap the clamp in a counter-clockwise direction to remove the clamp and lid. 2. Fill the pump pot and volute up to the inlet port with water. 3. Reinstall the lid by placing the lid on the pot. Be sure the lid O-ring is properly placed. Seat the clamp and lid on the pump then turn clockwise until the handles are horizontal. 4. Open the manual air relief valve on top of the filter. 5. Stand clear of the filter and start the pump. 6. When a steady stream of water flows from the Manual Air Relief Valve, close the valve. 7. The filtration system should now be free of air and recirculating water.
