5. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your sewage pump. Consult a qualified plumber or electrician if you are unsure about any steps.
5.1 Pre-Installation Checklist
- Verify that the power supply matches the pump's voltage requirements.
- Ensure the sump basin is clean and free of debris.
- Confirm that the discharge piping is correctly sized (2 inches minimum) and free of obstructions.
- Have all necessary tools and materials ready, including PVC cement, pipe wrenches, and electrical supplies.
5.2 Installation Steps
- Positioning the Pump: Place the pump on a solid, level surface at the bottom of the sump basin. Ensure it is not resting directly on soft sediment.
- Discharge Piping: Connect the pump's discharge port to the existing discharge piping using appropriate fittings and sealant. A check valve should be installed above the pump to prevent backflow.
- Electrical Connection: Connect the pump to a dedicated, grounded electrical circuit. Use a Ground Fault Circuit Interrupter (GFCI) outlet for added safety. Ensure the power cord is not pinched or damaged.
- Float Switch (if applicable): If your model includes a float switch, ensure it is positioned correctly to activate and deactivate the pump at desired water levels without obstruction.
- Testing: After installation, slowly fill the sump basin with water to test the pump's operation. Observe for proper activation, discharge, and deactivation. Check for any leaks.
6. Operating Instructions
The Glentronics E7055-NS pump is designed for automatic operation when connected to a float switch system. Manual operation is not typically recommended for sewage applications.
6.1 Automatic Operation
- Once properly installed and connected to power, the pump will activate automatically when the water level in the sump basin rises to the float switch's "ON" position.
- The pump will continue to operate, discharging wastewater, until the water level drops to the float switch's "OFF" position.
- Ensure the float switch has a clear range of motion and is not obstructed by the basin walls or other components.
6.2 Initial Start-up
During the first few cycles, monitor the pump to ensure it is functioning correctly. Listen for unusual noises and check for proper water flow and complete drainage of the basin.
7. Maintenance
Regular maintenance helps ensure the longevity and reliable performance of your sewage pump.
7.1 Routine Checks (Monthly/Quarterly)
- Power Disconnection: Always disconnect power before any inspection or maintenance.
- Sump Basin Inspection: Check the sump basin for excessive debris, sludge buildup, or foreign objects that could impede pump operation or float switch movement.
- Float Switch Check: Manually lift and lower the float switch to ensure it moves freely and activates/deactivates the pump correctly.
- Discharge Piping: Inspect the discharge pipe and check valve for any signs of leaks or blockages.
- Power Cord: Examine the power cord for any cuts, abrasions, or damage. Replace if necessary.
7.2 Cleaning
If significant sludge or debris accumulates, the pump may need to be removed from the basin for thorough cleaning. Use a stiff brush and water to clean the pump housing and impeller area. Ensure all debris is removed from the impeller vanes.
CAUTION: Do not use harsh chemicals or solvents that could damage pump components.
8. Troubleshooting
This section provides solutions to common issues you might encounter with your sewage pump.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start | No power; Tripped circuit breaker/GFCI; Faulty float switch; Motor overload. | Check power supply; Reset breaker/GFCI; Inspect/replace float switch; Allow motor to cool and reset thermal protector. |
| Pump runs but no water discharges | Clogged impeller or discharge pipe; Air lock; Check valve stuck closed. | Disconnect power, clear obstructions; Prime pump if air locked; Inspect/replace check valve. |
| Pump runs continuously | Stuck float switch; Leaking check valve; Continuous inflow. | Inspect/free float switch; Replace check valve; Investigate source of continuous water inflow. |
| Pump cycles too frequently | Float switch set too close; Leaking check valve; Small sump basin. | Adjust float switch settings; Replace check valve; Consider a larger sump basin if feasible. |
| Excessive noise or vibration | Debris in impeller; Worn bearings; Pump not sitting level. | Disconnect power, clear impeller; Contact service for bearing replacement; Ensure pump is level. |
If troubleshooting steps do not resolve the issue, contact Glentronics customer support or a qualified service technician.
