Setup Instructions
Proper setup ensures optimal performance and safety of your sump pump. Follow these steps for initial installation:
- Placement: Ensure the pump is placed on a level and solid foundation. Avoid placing it directly on soft ground or uneven surfaces.
- Submersion: Before connecting power, submerge the pump into the water at an inclined angle. This helps to remove any excess air trapped inside the pump, ensuring proper priming and operation.
- Hose Connection: The pump features an NPT1" discharge. Use the provided NPT1" to GHT3/4" adapter to accommodate various hose sizes. Securely attach your discharge hose to the pump's outlet.
- Power Connection: The pump is equipped with a 16 ft power cable, allowing for flexible placement without the immediate need for an extension cord. Plug the pump into a suitable power outlet.
- Clearance: Verify that the exhaust hole is not blocked by any debris, such as leaves or sediment, to ensure unrestricted water flow.
- Cable Management: Avoid moving the pump by pulling on the power cord. Always use the integrated handle for repositioning.

Operating Instructions
The LANCHEZ sump pump is designed for straightforward operation. It does not feature an automatic start/stop mechanism; operation is controlled by plugging and unplugging the unit.
- Starting the Pump: Once properly set up and submerged, simply plug the pump into a grounded electrical outlet to begin operation.
- Stopping the Pump: To stop the pump, unplug it from the electrical outlet.
- Water Level: The pump is capable of removing water down to a low level of 0.35 inches, making it effective for nearly complete drainage.
- Application: This pump is suitable for a wide range of applications including draining hot tubs, water tanks, swimming pools, standing water in basements, cellars, sump pits, rain barrels, and other flooded areas.
- Particle Size: Ensure that the diameter of any solid particles in the water does not exceed 34mm to prevent clogging or damage to the impeller.
- Water Temperature: The maximum allowable water temperature for operation is 95°F (35°C). Operating in water above this temperature may cause damage.
- Avoid Dry Running: Never operate the pump without water. Dry running can cause severe damage to the motor and seals.

Maintenance
Regular maintenance helps prolong the life and efficiency of your LANCHEZ sump pump.
- Cleaning: Periodically inspect the pump's intake screen and impeller for debris, such as leaves, dirt, or small stones. Clear any blockages to maintain optimal flow and prevent damage.
- Storage: When not in use for extended periods, clean the pump thoroughly, drain any remaining water, and store it in a dry, protected area away from extreme temperatures.
- Thermal Overload Protection: The pump features a built-in automatic thermal overload protector. If the pump overheats due to continuous work or blockage, it will automatically shut down to prevent damage. Allow the pump to cool down sufficiently before attempting to restart it.
- Casing Inspection: The pump is constructed with a robust and corrosion-resistant thermoplastic casing. Regularly inspect the casing for any signs of cracks or damage.

Troubleshooting
If you encounter issues with your LANCHEZ sump pump, refer to the following common troubleshooting steps. For more detailed guidance, please consult the official Troubleshooting Guide (PDF).
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start. | No power; pump not properly submerged/airlocked; thermal overload activated. | Check power connection and circuit breaker. Submerge pump at an incline to release air. Allow pump to cool down if it was running continuously. |
| Reduced flow or no water discharge. | Clogged intake screen or impeller; kinked or blocked discharge hose; pump not fully primed. | Unplug pump and clear any debris from the intake and impeller. Straighten the discharge hose. Re-submerge the pump at an incline to ensure it is primed. |
| Pump runs but no water is discharged. | Airlock in the pump; discharge hose blocked or too long/high. | Unplug and re-submerge the pump at an angle to release trapped air. Check the discharge hose for blockages or excessive vertical lift. |
| Pump stops unexpectedly. | Thermal overload protection activated; power interruption; dry running. | Allow pump to cool down. Check power supply. Ensure pump is always submerged in water during operation. |
