5. Setup
Follow these steps to prepare your sump pump for operation:
- Attach the Discharge Fitting: Select the appropriate hose adapter for your application. The pump supports 1-inch NPT, GHT 3/4-inch for garden hoses, and adapters for 1-1/2, 1-1/4, or 1-inch hoses. Securely screw the chosen adapter onto the pump's discharge outlet.
- Connect the Hose: Attach your discharge hose to the adapter. Use a hose clamp if necessary to ensure a tight, leak-free connection, especially for larger hoses.
- Position the Pump: Place the pump in the area to be drained, ensuring it is fully submerged in water. The minimum water level for effective operation is approximately 4 inches (10 cm) above the pump base.
- Route the Discharge Hose: Ensure the discharge hose is routed away from the area to be drained and leads to a suitable drainage point. Avoid kinks or sharp bends in the hose.

6. Operating Instructions
Once the pump is set up and submerged:
- Initial Submersion: Ensure the pump is fully submerged in water. For first-time use or after prolonged storage, allow the pump to sit submerged for 2-3 minutes to ensure all air is expelled from the pump body before connecting power.
- Connect Power: Plug the 16.4ft power cord into a compatible 110V 60Hz electrical outlet. The pump will begin operating automatically.
- Monitor Operation: Observe the pump's operation to ensure water is being discharged effectively. The pump is designed to handle clean or dirty water with solids up to 38mm.
- Automatic Shut-off: The pump is equipped with a float switch (if applicable to your model, check specifications) that will automatically turn the pump off when the water level drops below a certain point (typically around 1.4 inches residual water level).
- Disconnect Power: Once the desired water level is reached or the pump has automatically shut off, disconnect the power cord from the outlet.
