- Motor: 1.6HP permanent magnet separation capacitor motor with 1200W power.
- Pressure Tank: 5-gallon capacity to maintain consistent water pressure.
- Pressure Gauge: Displays real-time pressure within the system.
- Automatic Pressure Switch: Automatically turns the pump ON when pressure drops below 20 PSI and OFF when it reaches 40 PSI.
- Safety Switch: Provides overheat protection and is IPX4 rated.
- Slide Valve: For easy operation and control.
- Heat Dissipation Vent: Ensures proper cooling of the motor.
- Inlet (1" NPT): Connection point for water intake.
- Outlet (1" NPT): Connection point for water discharge.
- Non-slip Base: Provides stability during operation.
- Power Cord: 4 ft long cord for electrical connection.
4. Setup and Installation
Proper installation is crucial for optimal performance and longevity of your pump.
4.1 Site Selection
- Choose a dry, level, and well-ventilated location.
- Ensure the pump is protected from direct sunlight, rain, and freezing temperatures.
- Place the pump as close to the water source as possible to minimize suction lift.
4.2 Plumbing Connections
- Connect the suction line (from the water source) to the 1" NPT Inlet.
- Connect the discharge line (to your irrigation system or home) to the 1" NPT Outlet.
- Use appropriate thread sealant on all connections to prevent leaks.
- Ensure all pipes are securely fastened and supported.
4.3 Priming the Pump
Before first use or after the pump has run dry, it must be primed:

- Ensure all connections are tight.
- Locate the priming port (usually a cap on top of the pump housing).
- Remove the priming cap.
- Slowly fill the pump housing with clean water until it overflows.
- Replace the priming cap securely.
- The pump is now primed and ready for operation.

5. Operating Instructions
Follow these steps for safe and effective operation of your Goplus pump.
- Ensure the pump is properly primed (see Section 4.3).
- Verify all connections are secure and leak-free.
- Plug the power cord into a grounded 120V/60Hz electrical outlet.
- Turn on the safety switch. The pump will start automatically when the pressure drops below 20 PSI and stop when it reaches 40 PSI.
- Monitor the pressure gauge to ensure proper operation.
- After use, if the pump will not be used for an extended period, disconnect power and drain the pump to prevent freezing.

6. Maintenance
Regular maintenance ensures the longevity and efficient operation of your pump.
- Cleaning: Periodically clean the exterior of the pump. Do not use harsh chemicals.
- Winterization: In cold climates, drain the pump completely before freezing temperatures to prevent damage. Store in a dry, warm place.
- Inspection: Regularly inspect the power cord, connections, and pump housing for any signs of wear or damage.
- Priming: Re-prime the pump if it runs dry or after maintenance that involves draining the system.
7. Troubleshooting
Refer to this section for common issues and their potential solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start | No power; tripped circuit breaker; faulty switch. | Check power connection; reset breaker; inspect switch. |
| Pump runs but no water flows | Pump not primed; air leak in suction line; clogged inlet. | Prime the pump; check suction line for leaks; clear inlet. |
| Low water pressure | Partial clog; air in system; worn impeller. | Check for clogs; re-prime; contact service for impeller replacement. |
| Pump cycles too frequently | Pressure tank issue; small leak in system. | Check pressure tank air charge; inspect system for leaks. |
| Pump overheats and shuts off | Motor overload; insufficient ventilation; running dry. | Allow to cool; ensure proper ventilation; ensure pump is primed. |
