2. Safety Information
Always observe the following safety precautions to reduce the risk of electric shock, fire, or injury:
- Electrical Safety: Ensure the power supply matches the pump's voltage (115 Volts). Use a grounded outlet. Do not operate with a damaged cord or plug.
- Water Immersion: This pump is designed for submersible use only. Do not operate it dry.
- Handling: Always lift the pump by its handle. Never pull the pump by the power cord or discharge hose.
- Temperature: Do not pump flammable liquids or water above 95°F (35°C).
- Debris: Ensure the pump's intake and exhaust holes are clear of debris to prevent blockages and overheating.
- Children and Pets: Keep children and pets away from the operating pump and any standing water.

4. Setup Instructions
- Attach Discharge Hose:
Select the appropriate hose adapter for your discharge hose. The pump includes adapters for NPT 1-1/2", GHT 3/4", Φ1-1/2", Φ1-1/4", and Φ1" hoses. Securely attach the chosen adapter to the pump's discharge outlet.

- Position the Pump:
Place the pump on a level and solid foundation in the area to be drained. Ensure the pump is fully submerged in water before operation. The maximum submersible depth is 14 feet.

- Adjust Base for Water Type (Optional):
The pump features an adjustable base. For clean water, turn the base up. For sewage or water with larger particles, turn the base down to allow for pumping down to 0.04 inches.

- Initial Priming:
Before starting, tilt and submerge the pump in water for a few seconds to expel any trapped air inside. This prevents dry running and ensures efficient operation.

5. Operating Instructions
5.1 Automatic Mode
- Connect Power: Plug the 10-foot power cord into a grounded 115-volt electrical outlet.
- Float Switch Position: Ensure the float switch is free to move. The pump will automatically start when the water level rises above approximately 7 inches and will shut off when the water level drops below approximately 1.5 inches.
- Monitor Operation: Observe the pump's operation to ensure water is being drained effectively.

5.2 Manual Mode
For continuous operation, the float switch can be locked into its bracket.
- Lock Float Switch: Secure the float switch in the "up" position using the integrated bracket on the pump handle.
- Connect Power: Plug the pump into a grounded 115-volt electrical outlet. The pump will run continuously.
- Disconnect Power: To stop the pump in manual mode, unplug it from the power outlet. Do not allow the pump to run dry for extended periods.

6. Maintenance
- Regular Cleaning: Periodically inspect the pump's intake screen and impeller for debris. Clean as necessary to maintain optimal performance.
- Winterization: In cold climates, if the pump is not in use, drain all water from the pump and hoses to prevent freezing and damage. Store in a dry, frost-free location.
- Power Cord Inspection: Regularly check the power cord for any signs of damage. Do not use the pump if the cord is frayed or cut.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start. | No power; float switch not activated (automatic mode); thermal overload activated. | Check power connection and circuit breaker. Ensure water level is above float switch activation point. Allow pump to cool down if thermal overload tripped. |
| Pump runs but no water is discharged. | Air lock; clogged intake/discharge; low water level. | Tilt pump to release air. Clear any blockages from intake or hose. Ensure pump is fully submerged. |
| Pump cycles on and off too frequently. | Float switch obstruction; small pit size. | Ensure float switch moves freely. Consider a larger pit or check valve if applicable. |
| Reduced flow rate. | Partial blockage; worn impeller. | Clean intake screen and discharge hose. Inspect impeller for damage. |
