5. Setup and Installation

The VEVOR Under-Sink Sump Pump System is designed for straightforward installation. Follow these steps carefully:

1. Placement: Position the pump system in a suitable location, typically under a sink or near the appliance requiring drainage. Ensure it is on a stable, level surface.
2. Connect Inlet Pipes: Connect the drainage pipes from your wash basin, bathtub, shower, or washing machine to the inlet ports of the pump. Use the provided input connectors and clamps to secure connections, ensuring they are watertight. The pump features a user-friendly bottom inlet for unrestricted drainage.
3. Connect Output Pipe: Attach the output tube to the pump's discharge outlet. Secure it with the appropriate clamp. Connect the other end of the output tube to your main drainage system, ensuring a proper seal and a slight downward slope for gravity assistance if possible.
4. Secure the System: Use the provided positioning plates and screws to secure the pump system to the floor or wall, if desired, to prevent movement during operation.
5. Electrical Connection: Plug the pump into a grounded 120-Volt AC 60Hz electrical outlet. Ensure the circuit is protected by a Ground Fault Circuit Interrupter (GFCI).
6. Test Operation: Once all connections are secure, introduce water into the system to test the pump's automatic operation. The pump should activate when the water level rises and shut off once the water is drained.

6. Operating Instructions

The VEVOR Under-Sink Sump Pump System operates automatically based on water levels.

• Automatic Operation: Once properly installed and connected to power, the pump will automatically activate when the water level inside the unit reaches the designated starting level (approximately 3.94 inches / 100 mm).
• Automatic Shut-off: The pump will continue to operate until the water level drops to the designated stopping level (approximately 0.79 inches / 20 mm), at which point it will automatically shut off.
• Continuous Monitoring: The system continuously monitors the water level, ensuring efficient and timely drainage without manual intervention.

7. Maintenance

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

• Disconnect Power: Always disconnect the pump from the power supply before any maintenance.
• Inspect Connections: Periodically check all pipe connections for leaks and ensure clamps are tight.
• Clean Inlet/Outlet: Inspect the inlet and outlet ports for any debris or blockages. Clear any obstructions to maintain optimal flow.
• Check for Debris: Occasionally, inspect the pump chamber for any accumulated debris that might interfere with the float switch or impeller.
• Winterization (if applicable): If the pump is in an area subject to freezing temperatures and will not be used, drain all water from the system to prevent damage from freezing.
