1. Introduction
Thank you for choosing the Pretul BOS-1-1/2SPP Submersible Plastic Pump. This manual provides essential information for the safe and efficient operation, installation, and maintenance of your pump. Please read these instructions carefully before use and retain them for future reference.
This pump is designed for pumping dirty water, suitable for drainage and flood control applications. It features a robust 1-1/2 HP motor with aluminum coils, a suction base with a particle filter grille, and a capacitor for enhanced starting power.
2. Safety Information
Always observe the following safety precautions to prevent personal injury or damage to the pump:
- Electrical Safety: Ensure the power supply matches the pump's requirements. Do not operate the pump with damaged cables or plugs. Always connect to a grounded outlet. Never touch the pump or water while it is connected to power.
- Water Type: This pump is designed for dirty water. Do not use it for potable water, flammable liquids, corrosive chemicals, or highly abrasive materials.
- Immersion Depth: Do not exceed the maximum immersion depth of 7 meters. Ensure the pump is fully submerged during operation to prevent overheating.
- Temperature: Do not pump liquids hotter than 35°C (95°F).
- Children and Pets: Keep children and pets away from the pump and the area of operation.
- Maintenance: Always disconnect the pump from the power supply before performing any maintenance or cleaning.

This graph illustrates the relationship between the pump's flow rate (L/min) and the maximum head (height in meters) it can achieve. Use this curve to determine the pump's performance under different operating conditions.
5. Setup
- Unpacking: Carefully remove the pump and all accessories from the packaging. Inspect for any damage.
- Hose Connection: Attach a suitable discharge hose to the hose adapter. The adapter supports various hose and pipe sizes (1", 1-1/4", 1-1/2"). Ensure a secure, leak-free connection.
- Positioning: Place the pump on a stable, flat surface in the water to be drained. Ensure the pump is fully submerged and not resting directly on mud or debris that could block the suction base.
- Float Switch Adjustment: Adjust the float switch cable length to control the automatic on/off levels. A shorter cable will result in a smaller operating range (pump turns on/off with less water level change), while a longer cable allows for a wider range. Ensure the float switch can move freely without obstruction.
- Power Connection: Connect the pump's power cable to a grounded electrical outlet that matches the pump's voltage requirements.
6. Operating Instructions
- Initial Start-up: Once the pump is correctly positioned and connected, plug it into the power outlet. The pump will start automatically when the water level rises and activates the float switch.
- Automatic Operation: The float switch will turn the pump on when the water reaches a certain level and turn it off when the water level drops below the minimum required for operation.
- Manual Operation (if applicable): If your model allows for manual override, ensure the float switch is in the 'on' position or manually held up to keep the pump running continuously. Always monitor the pump during manual operation to prevent dry running.
- Monitoring: Periodically check the discharge flow and ensure the pump is operating smoothly. Listen for unusual noises or vibrations.
- Shutting Down: To stop the pump, unplug it from the power outlet. If operating automatically, it will stop when the water level drops.
Important: Avoid dry running the pump, as this can cause severe damage to the motor and seals. Ensure the pump is always fully submerged during operation.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your pump.
- Cleaning the Suction Base: Regularly inspect and clean the particle filter grille on the suction base to prevent blockages. Disconnect power before cleaning.
- Impeller Inspection: If the pump's performance decreases, the impeller might be clogged. Disconnect power, remove the suction base (if detachable), and clear any debris from the impeller area.
- Storage: When not in use for extended periods, clean the pump thoroughly, drain all water, and store it in a dry, frost-free location.
- Cable Inspection: Periodically check the power cable for any signs of wear, cuts, or damage. Replace immediately if damaged.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start | No power supply Float switch not activated Motor overload | Check power connection and circuit breaker Ensure water level is high enough to activate float switch Disconnect power, let pump cool, check for blockages |
| Pump runs but no water is discharged or flow is low | Suction base or impeller clogged Air lock Discharge hose kinked or blocked | Disconnect power, clean suction base and impeller Ensure pump is fully submerged and free of air pockets Check and clear discharge hose |
| Pump stops unexpectedly | Float switch deactivated (low water level) Thermal overload protection activated | Wait for water level to rise or manually activate float switch Disconnect power, let pump cool down, check for blockages or dry running |
| Excessive noise or vibration | Debris in impeller Pump not stable | Disconnect power, clean impeller Ensure pump is on a flat, stable surface |
