Installation Guide

Proper installation is critical for optimal performance. Follow these steps:

1. Preparation: Verify well dimensions and water quality. Ensure the well is clean and free of sediment.
2. Motor Filling: Fill the motor cavity with clean water and tighten the water bolt.
3. Cable Connection: Use waterproof cables and ensure proper insulation to prevent electrical faults.
4. Mounting: Secure the pump vertically in the well, maintaining a minimum 3-meter distance from the well bottom.
5. Testing: Conduct a short test run to check for leaks, vibrations, or irregularities.

Maintenance and Care

To ensure longevity, regular maintenance is essential:

• Inspect the motor’s insulation resistance monthly using a 500V megohmmeter.
• Check for wear on the impeller, shaft sleeve, and sealing ring.
• Replace worn parts promptly to avoid downtime.
• Store the pump in a dry, corrosion-free environment when not in use.

Safety Precautions

Follow these guidelines to ensure safe operation:

• Never operate the pump without water to prevent motor damage.
• Ensure the pump is fully submerged to avoid overheating.
• Use a grounded power supply and install overload protection devices.
• Regularly check for electrical faults and mechanical wear.
