5. Setup and Installation
The Wayne CDU980E sump pump is designed for installation in 11-inch diameter or larger sump pits. Follow these steps for proper installation:
- Prepare the Sump Pit: Ensure the sump pit is clean and free of debris. The pump should sit on a solid, level surface.
- Connect Discharge Pipe: Thread a 1-1/2 inch NPT discharge pipe into the pump's outlet. Use appropriate sealant for a watertight connection.
- Install Check Valve: Install a check valve in the discharge line above the pump to prevent water from flowing back into the sump pit when the pump shuts off.
- Position the Pump: Carefully lower the pump into the sump pit. Ensure the float switch can move freely without obstruction from the pit walls or other pipes.
- Electrical Connection: Plug the pump into a properly grounded 120V, 60Hz electrical outlet protected by a GFCI. Ensure the power cord is routed to prevent damage.
- Test Operation: Pour water into the sump pit to verify the float switch activates the pump and discharges water correctly.

6. Operating Instructions
The Wayne CDU980E operates automatically via its integrated vertical float switch. When water in the sump pit rises and lifts the float to the 'ON' level (approximately 9 inches), the pump will activate and begin discharging water. Once the water level drops and the float returns to the 'OFF' level (approximately 4 inches), the pump will shut off. This automatic operation ensures your basement remains dry without constant manual intervention.

7. Maintenance
Regular maintenance helps ensure the longevity and reliable operation of your sump pump:
- Inspect Regularly: Periodically check the sump pit for debris that could obstruct the float switch or pump intake.
- Clean Intake Screen: Ensure the pump's intake screen is clear of leaves, dirt, or other foreign objects.
- Test Float Switch: Manually lift the float switch to ensure the pump activates and deactivates correctly. This should be done monthly, especially during rainy seasons.
- Check Discharge Line: Verify that the discharge pipe is not clogged or frozen, especially in colder climates.
- Power Cord Inspection: Check the power cord for any signs of damage or wear.
8. Troubleshooting
| Problem | Possible Cause | Solution |
