2. Safety Information

Always observe basic safety precautions to reduce the risk of fire, electric shock, and personal injury.

Electrical Safety: Ensure the pump is connected to a properly grounded 115V AC outlet. Do not modify the plug. Do not operate the pump with a damaged cord or plug.
Submersible Use Only: This pump is designed for submersible applications. Do not operate it dry, as this can cause motor damage and activate the built-in thermal overload protection.
Handling: Never lift or carry the pump by its power cord or float switch cable. Use the integrated handle or a rope attached to the designated pull ring.
Water Temperature: Do not use the pump with water temperatures exceeding 95°F (35°C).
Hazardous Materials: Do not use the pump to handle flammable, corrosive, or explosive liquids.
Maintenance: Always disconnect power before performing any maintenance or cleaning on the pump.

5. Setup and Installation

Follow these steps for proper installation of your submersible sewage pump:

Placement: Position the pump on a stable, level surface within the sump basin, sewage well, or other application area. Ensure the pump is placed at the bottom and is not obstructed.
Discharge Pipe Connection: Connect a properly sized water hose or rigid pipe (2-inch NPT) to the pump's discharge port. Ensure all connections are secure and watertight.
Float Switch Adjustment: The pump comes with a piggyback tethered float switch. The float switch determines the automatic ON/OFF levels. Adjust the tether length to set the desired operating range. The pump will turn ON when the water level reaches approximately 15.7 inches and turn OFF when it drops to about 9.8 inches.
Power Connection: Plug the pump's power cord into a grounded 115V AC electrical outlet. For automatic operation, ensure the float switch plug is connected to the main power plug (piggyback configuration). For manual operation, the float switch plug can be bypassed by plugging the main power cord directly into the outlet.
Secure Lifting: When lowering or raising the pump, always use the integrated pull ring or a sturdy rope. Never lift the pump by its power cord or float switch cable.

Operating instructions showing three steps: 1. Connect a properly sized water hose (2 inch NPT). 2. Put the pump into the water, paying attention to the bottom to be placed firmly. 3. Auto Mode: Connect the power cord with the float switch wire. Manual Mode: Directly plug the power cord into the socket.

6. Operating Instructions

The LANCHEZ sewage pump offers two operating modes:

Automatic Mode: This is the recommended mode for most applications. With the piggyback float switch properly connected and adjusted, the pump will automatically activate when the water level rises to approximately 15.7 inches and deactivate when the water level drops to about 9.8 inches. This prevents dry running and ensures efficient water removal.
Manual Mode: For continuous operation, the float switch can be bypassed by plugging the pump's main power cord directly into the electrical outlet. In manual mode, the pump will run continuously until unplugged. Caution: Do not operate the pump in manual mode without constant supervision to prevent dry running, which can damage the motor.

Two images showing the automatic float switch operation. One image shows the pump stopping when the water level is OFF at 9.84 inches, and the other shows it starting when the water level is ON at 15.75 inches.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your pump. Always disconnect the pump from the power source before performing any maintenance.

Regular Inspection: Periodically inspect the pump for any visible damage, especially to the power cord and float switch cable.
Impeller Cleaning: If the pump's performance decreases, the non-clog vortex impeller may have accumulated debris. Carefully remove the pump from the basin and inspect the impeller area for obstructions. Clear any debris gently.
Float Switch Check: Ensure the float switch moves freely and is not obstructed by debris or the basin walls.
Discharge Pipe: Check the discharge pipe for any blockages or leaks.
Winterization (if applicable): If the pump is used in an area subject to freezing temperatures and will not be in use, remove it from the water, clean it thoroughly, and store it in a dry, frost-free location.

8. Troubleshooting

Refer to the following table for common issues and their solutions:

Problem	Possible Cause	Solution
Pump does not start	No power; Float switch stuck; Impeller jammed; Thermal overload activated	Check power supply and circuit breaker; Ensure float switch moves freely; Clear impeller of debris; Allow pump to cool down if thermal overload tripped.
Pump runs continuously	Float switch stuck in ON position; Pump in manual mode	Check float switch for obstructions; Ensure pump is in automatic mode (piggyback plug connected).
Reduced flow or no water pumped	Discharge pipe blocked; Impeller partially clogged; Air lock; Low water level	Check and clear discharge pipe; Clean impeller; Ensure pump is fully submerged and free of air pockets; Verify water level is above the ON threshold.
Pump makes unusual noise	Debris in impeller; Worn bearings	Disconnect power and clear impeller; If noise persists, contact customer support.
