PULACO 50GPH 3W Mini Submersible Water Pump User Manual

1. Important Safety Information

Please read all safety instructions carefully before operating the PULACO Mini Submersible Water Pump. Failure to follow these instructions may result in product damage or personal injury.

• Full Submersion Required: This pump is designed for submersible use only. It must be fully immersed in water before connecting to power. Operating the pump dry (no-load running) will cause it to overheat, shorten its lifespan, and may lead to permanent damage or loud noises.
• Power Disconnection: Always disconnect the power supply to the pump before performing any maintenance, cleaning, or when changing water in the tank or pond.
• Regular Cleaning: To prevent debris blockage and maintain optimal performance, clean the pump regularly, approximately once every two months. Debris can cause the pump to stop working or produce excessive noise.
• Protection for Small Aquatic Life: The pump features a strainer design. If used in environments with small fish or aquatic life, ensure adequate isolation or protection to prevent them from being drawn into the pump's front strainer.
• Electrical Safety: Ensure the power outlet and connections are dry and free from water contact. This pump operates on 110 Volts AC.

4. Setup and Installation
