• Ensure you have a suitable 12-volt deep cycle battery (e.g., WAYNE WSB1275 75 AH Battery).
• Verify your sump basin is at least 14 inches in diameter to accommodate the unit.
• Gather necessary tools: screwdriver, pipe wrench, PVC cement, tape measure, etc.
• Review the full Installation Manual (PDF) for detailed instructions.

4.2 Installation Steps

1. Prepare the Sump Basin: Ensure the sump basin is clean and free of debris.
2. Position the Pump: Place the ESP25 pump unit in the sump basin. Its compact design allows it to fit in 14-inch diameter or larger basins.
3. Connect Discharge Pipe: Connect the pump to your existing discharge piping. The unit is designed for easy integration.
4. Install Float Switch: The integrated vertical float switch should be positioned to activate the pump at the desired water level. No need to drill a weep hole.
5. Connect Battery: Place the 12-volt deep cycle battery (not included) inside the protective battery box. Connect the battery cables from the pump system to the battery terminals, ensuring correct polarity (red to positive, black to negative).
6. Connect Power: Plug the system's power adapter into a standard 120V AC outlet. The system will begin charging the battery and monitoring water levels.
7. Test Operation: Manually lift the float switch to ensure the pump activates and discharges water correctly. Verify the LED display and audible alarm function.

5. Operating Instructions

5.1 Automatic Operation

The Wayne ESP25 system operates automatically. The integrated vertical float switch monitors the water level in your sump basin. When the water level rises to a predetermined point, the float switch activates the pump, which then removes the water from the basin. Once the water level drops, the pump will automatically shut off.

5.2 Battery Backup Function

In the event of a power outage, the system seamlessly transitions to battery power. The 12-volt battery (not included) provides the necessary power to continue pumping, ensuring your basement remains dry even when the main power supply is interrupted. The system's smart charging technology maintains the battery at optimal levels when AC power is available.

An audible alarm and LED display on the protective battery case will notify you if there is a problem or if the backup system is active, providing immediate alerts to potential issues.

6. Maintenance

Regular maintenance ensures the longevity and reliable operation of your Wayne ESP25 system:

• Monthly Check: Test the system monthly by manually lifting the float switch to ensure the pump activates. Verify water is discharged and the alarm sounds if applicable.
• Battery Inspection: Check battery terminals for corrosion and clean if necessary. Ensure the battery is fully charged. Replace the battery every 3-5 years, or as recommended by the battery manufacturer.
• Sump Basin Cleaning: Periodically inspect the sump basin for debris, dirt, or sediment that could obstruct the pump or float switch. Clean as needed.
• Discharge Pipe Check: Ensure the discharge pipe is free of blockages and that the check valve (if installed) is functioning correctly.
