WASSERMANN 3/4 HP Submersible Sewage Pump Instruction Manual

Model: 3/4SEP215-SJEC

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, Model 3/4SEP215-SJEC. Please read these instructions thoroughly before installation and use to ensure proper function and to prevent injury or damage. Keep this manual for future reference.

2. Safety Information

WARNING: Failure to follow these safety instructions could result in electric shock, fire, serious injury, or death.

Always disconnect power before servicing the pump.
Do not lift the pump by its electrical cord. Use the designated lifting ring or ropes.
Ensure the pump is fully immersed in water during operation to prevent overheating.
This sewage pump is designed for water. Do not use it for flammable, explosive, or corrosive liquids such as oil, gasoline, kerosene, or ethanol.
Do not override the float switch to force the pump to work in low water levels, as this can damage the motor and shaft seal.
When a check valve is used, drill a relief hole (1/8" or 3/16" in diameter) in the discharge pipe to prevent air lock.
Ensure all electrical connections are properly grounded and protected by a Ground Fault Circuit Interrupter (GFCI).

4. Setup and Installation

Follow these steps for proper installation of your WASSERMANN sewage pump.

Prepare the Discharge Pipe: Connect the water hose or PVC pipe to the 2" NPT discharge outlet. Ensure a secure, watertight connection. If using PVC, apply PVC glue as needed.
Drill Air Lock Relief Hole: If a check valve is used in your system, drill a 1/8" or 3/16" diameter relief hole in the discharge pipe, approximately 6 inches above the pump's discharge outlet. This prevents air lock.
Seal Threads (if applicable): For threaded connections, wrap Teflon tape around the threads of the discharge pipe to ensure a tight seal.
Position the Pump: Place the pump in the sump basin or sewage well, ensuring it rests on a stable, level surface. The float switch should have free movement and not be obstructed by the basin walls or other components.
Electrical Connection:
- For Automatic Function: Connect the pump's plug to the float switch's plug, then plug the float switch's plug into a properly grounded 115V AC outlet protected by a GFCI.
- For Manual Function: Connect only the pump's plug directly into a properly grounded 115V AC outlet protected by a GFCI. The pump will run continuously when powered.

5. Operating Instructions

Automatic Operation:

When the pump is connected for automatic function (pump plug connected to float plug, then float plug to outlet), the pump will start and stop based on the water level. The float switch activates the pump when the water reaches a fixed "ON" level (approximately 11 inches) and deactivates it when the water drops to a fixed "OFF" level (approximately 6 inches). Ensure the float switch moves freely and is not obstructed.

Manual Operation:

For continuous operation, connect the pump's power plug directly to a grounded 115V AC outlet. The pump will run continuously as long as it is powered. Monitor the water level to prevent dry running, which can damage the pump.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your pump.

Monthly Inspection: Check the pump and float switch for any debris, blockages, or damage. Ensure the float switch moves freely.
Cleaning: Periodically remove the pump from the basin and clean any accumulated sludge or debris from the impeller and pump housing.
Power Cord Inspection: Inspect the power cord for any cuts, fraying, or damage. Replace if necessary.
Winterization (if applicable): If the pump is in an area subject to freezing temperatures and will not be used, remove it, clean it thoroughly, and store it in a dry, frost-free location.

7. Troubleshooting

Before attempting any repairs, always disconnect the pump from the power source.

Problem	Possible Cause	Solution
Pump does not start.	No power; tripped GFCI; float switch obstructed or faulty; motor overload.	Check power supply and GFCI. Ensure float switch moves freely. Allow motor to cool if overloaded.
Pump runs but no water is discharged.	Discharge pipe blocked; air lock; impeller clogged; water level too low.	Clear blockage. Check for air lock relief hole. Clean impeller. Ensure adequate water level.
Pump runs continuously.	Float switch stuck in "ON" position; pump connected for manual operation.	Check float switch for obstructions. Verify correct electrical connection for automatic mode.
Pump cycles too frequently.	Check valve leaking; small sump basin; float switch setting.	Inspect and repair/replace check valve. Consider a larger sump basin if feasible. Adjust float switch if possible (not applicable for fixed floats).
