1. Introduction
This manual provides essential information for the safe and efficient operation, installation, and maintenance of your WASSERMANN 3/4 HP Submersible Sewage Pump. Please read all instructions carefully before use and retain this manual for future reference.
The WASSERMANN 3/4 HP submersible sewage pump is designed for demanding drainage tasks, featuring a high-efficiency oil-filled split capacitor motor. It is suitable for applications such as basement drainage, sump basin sewage wells, and other dirty water pumping needs.
2. Safety Information
- Electrical Safety: Ensure the power supply matches the pump's voltage (115V). Always connect to a properly grounded outlet. Do not operate with damaged cords or plugs.
- Immersion: The pump must be fully immersed in water during operation to prevent overheating.
- Liquid Compatibility: This sewage pump is designed for water. Do not use it for flammable, explosive, corrosive liquids, such as oil, gasoline, kerosene, or ethanol.
- Float Switch: Do not override the float switch to force the pump to work in low water levels. This can damage the motor and shaft seal.
- Handling: Never lift the pump by its power cord. Use ropes or the lifting ring provided.
- Air Lock Prevention: When using a check valve, drill a relief hole (1/8" or 3/16" in diameter) in the discharge pipe to prevent air lock.

- 10 FT Power Cable
5. Setup and Installation
Follow these steps for proper installation of your sewage pump:
- Prepare the Discharge Pipe: Connect PVC pipes using appropriate glue.
- Drill Anti-Airlock Hole: If a check valve is used, drill a 3/16-inch hole in the discharge pipe, approximately 6 inches above the pump's discharge outlet, to prevent air lock.
- Seal Connections: Wrap Teflon tape around the threaded connections of the discharge pipe to ensure a watertight seal.
- Install PVC Pipes: Securely attach the prepared PVC discharge pipe to the pump's 2-inch NPT discharge outlet.
- Position the Pump: Place the pump in the sump basin or sewage well, ensuring it is stable and fully immersed.
- Connect Power: For automatic operation, connect the pump's plug to the float switch plug, then plug the float switch into a grounded power outlet. For manual operation, plug the pump directly into a grounded power outlet.

6. Operating Instructions
The WASSERMANN sewage pump offers both automatic and manual operating modes:
- Automatic Function: Connect the pump's power plug to the float switch plug, then connect the float switch plug to a power outlet. The pump will automatically start when the water level reaches the fixed 'ON' level (approximately 19 inches) and stop when it drops to the 'OFF' level (approximately 9 inches).
- Manual Function: Connect the pump's power plug directly to a power outlet. The pump will operate continuously as long as it is powered. Ensure the pump remains fully submerged to prevent damage.
The pump is ideal for various applications:
- Basement drainage
- Sump basin sewage wells
- Dirty pond water removal
- Sewage well pumping

7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your pump:
- Regular Inspection: Periodically check the pump, power cord, and float switch for any signs of damage or wear.
- Clean Impeller: If the pump's performance decreases, inspect the non-clogging vortex impeller for debris and clean as necessary.
- Clear Sump/Well: Keep the sump basin or sewage well free from excessive debris that could obstruct the pump or float switch.
- Winterization: In freezing climates, remove the pump from the water and store it in a warm, dry place to prevent ice damage.
8. Troubleshooting
If you encounter issues with your WASSERMANN sewage pump, consider the following common troubleshooting steps:
- Pump Not Starting: Check power connection, ensure the float switch is not obstructed and is reaching the 'ON' level in automatic mode. Verify the circuit breaker.
- Pump Running Continuously: Ensure the float switch is not obstructed and can freely drop to the 'OFF' level.
- Low Flow/No Pumping: Check for blockages in the intake or discharge pipe. Ensure the impeller is clear of debris. Verify the pump is fully submerged.
- Unusual Noise: Inspect for foreign objects in the impeller area. Ensure the pump is stable and not vibrating excessively.
If problems persist after attempting these steps, contact customer support.
