Always prioritize safety when operating electrical equipment near water. Read and understand all instructions before use.
- Electrical Safety: Ensure the pump is connected to a properly grounded outlet. Do not use damaged power cords or extension cords.
- Submersion: The pump must be fully submerged in water during operation to prevent dry running, which can cause damage.
- Placement: Place the pump on a stable, level, and solid foundation to ensure proper function and prevent tipping.
- Handling: Always lift the pump by its handle. Never pull or lift the pump by the power cord or float switch cable.
- Debris: Ensure the exhaust hole is not blocked by debris. The pump is designed to handle particles up to 4/5 inch (20mm).
- Temperature: Do not use the pump for liquids exceeding 95°F (35°C).
- Freezing: Prevent the pump from freezing. Completely empty the equipment and store it in a frost-free environment if not in use during cold weather.

5. Setup
Follow these steps to prepare your sump pump for operation:
- Attach Discharge Adapter: Select the appropriate adapter for your hose (1-1/2" NPT discharge, 3/4" garden hose, 1-1/2" elbow, or multi-hose adapter) and securely screw it onto the pump's discharge port.
- Connect Hose: Attach your drainage hose to the selected adapter. Ensure a tight connection to prevent leaks.
- Position Float Switch: The float switch controls automatic operation. For automatic mode, ensure the float can move freely. For manual operation in low water conditions, keep the float switch upright. The cable length of the float switch can be adjusted to alter its vertical position, which affects the trigger water levels.
- Place the Pump: Position the pump on a flat, stable surface in the area to be drained. Ensure it is fully submerged once water levels rise.
- Plug In: Connect the pump's power cord to a grounded 115V electrical outlet. The pump will activate once the water level reaches the float switch's minimum start level (5.3 inches) in automatic mode.

6. Operation
The LANCHEZ sump pump offers both automatic and manual operation modes:
- Automatic Mode: The integrated float switch automatically turns the pump ON when the water level reaches approximately 5.3 inches and turns it OFF when the water level drops to approximately 1.3 inches. Ensure the float switch has sufficient space to move freely.
- Manual Mode: For continuous operation in low water conditions, keep the float switch in an upright position. This bypasses the automatic on/off function.
- Submersion: Always ensure the pump is fully submerged in the water you intend to drain.
- Avoid Dry Running: Never operate the pump without water, as this can lead to overheating and permanent damage to the motor.

The float switch controls automatic pump operation based on water levels.

7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your sump pump:
- Cleaning: After each use, especially when pumping dirty water, rinse the pump thoroughly with clean water. Remove any accumulated debris from the intake screen and impeller.
- Inspection: Periodically inspect the power cord and float switch cable for any signs of damage, wear, or fraying. Replace if necessary.
- Storage: When not in use, store the pump in a dry, frost-free location. Ensure all water is drained from the pump and hose to prevent freezing damage.
- Thermal Overload Protection: The pump features an automatic thermal overload protector that will shut off the motor if it overheats. Allow the pump to cool down before restarting.
8. Troubleshooting
If your pump is not operating as expected, refer to the following common issues:
- Pump Not Starting:
- Check if the pump is properly plugged into a grounded outlet.
- Ensure the float switch is in the correct position for automatic or manual operation.
- Verify that the water level is above the minimum start level (5.3 inches) for automatic mode.
- Check for tripped circuit breakers or blown fuses.
- Low Flow or No Water Discharge:
- Inspect the intake screen and impeller for blockages (debris, leaves, etc.).
- Check the discharge hose for kinks, blockages, or improper connections.
- Ensure the pump is fully submerged and not drawing air.
- Pump Running Continuously:
- Check if the float switch is stuck in the 'ON' position or is obstructed.
- Ensure the water level drops below the minimum stop level (1.3 inches) for automatic mode.
- Pump Overheating:
- The pump may have run dry. Disconnect power, allow it to cool, and ensure it is fully submerged before restarting.
- Check for blockages that might be causing the motor to work harder than usual.
