• Always disconnect power before performing any installation, maintenance, or inspection procedures. Lock out and tag out the power source to prevent accidental re-energization.
• Installation and wiring must be performed by qualified personnel in accordance with all national and local electrical codes and safety regulations.
• Ensure proper grounding of the motor to prevent electrical shock.
• Protect rotating parts. Keep hands, clothing, and tools clear of the motor shaft and any connected equipment during operation.
• Do not operate the motor in environments exceeding its specified temperature or humidity ratings.
• Wear appropriate personal protective equipment (PPE), including safety glasses and gloves, when working with the motor.
• Verify that the motor's voltage and frequency ratings match the power supply before connection.

3. Setup and Installation

1. Unpacking and Inspection: Carefully remove the motor from its packaging. Inspect for any visible damage that may have occurred during shipping. Report any damage to the carrier immediately.
2. Mounting: This motor features a C-Face Flange mounting type. Ensure the mounting surface is flat, rigid, and capable of supporting the motor's weight (approximately 60 lbs) and any connected load. Secure the motor using appropriate fasteners.
3. Alignment: Proper alignment between the motor shaft and the driven equipment is crucial to prevent premature bearing failure and vibration. Use precision alignment tools for optimal results.
4. Electrical Connections:
   • Ensure the power supply is disconnected and locked out.
   • Connect the motor to a 3-phase power supply matching the motor's voltage rating (208-230/460 V). Refer to the motor's nameplate for specific wiring diagrams.
   • Ensure all connections are tight and properly insulated.
   • Verify proper grounding.
5. Initial Start-up: Before applying full load, perform a no-load test run to check for unusual noises, vibrations, or overheating. Verify correct rotation direction.

4. Operating Instructions

The Leeson Electric CZ6T17WC376A motor is designed for continuous duty in washdown environments. Once properly installed and connected, operation typically involves energizing the motor circuit. Observe the following:

• Monitoring: Regularly monitor the motor for unusual noises, excessive vibration, or overheating during operation.
• Load Management: Do not exceed the motor's rated horsepower (2 hp) or service factor (1.15). Overloading can lead to premature failure.
• Environmental Conditions: While designed for washdown, avoid direct high-pressure spray on the motor's electrical connections or bearings. Ensure proper drainage around the motor.
• Stopping: De-energize the motor circuit to stop operation.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your washdown duty motor.

• Cleaning: The stainless steel construction and TEFC enclosure make this motor suitable for washdown. Use mild detergents and low-pressure water for cleaning. Avoid harsh chemicals or high-pressure sprays directly on seals or electrical components.
• Bearing Inspection: The motor is equipped with ball bearings. While often sealed for life, periodic inspection for noise or excessive heat can indicate wear. Consult a qualified technician for bearing replacement if necessary.
• Shaft and Coupling: Inspect the motor shaft and coupling for wear, corrosion, or misalignment. Address any issues promptly.
• Electrical Connections: Periodically check all electrical connections for tightness and signs of corrosion.
• Ventilation: Ensure the fan cover and cooling fins are free from debris to maintain proper airflow and prevent overheating.

6. Troubleshooting

Refer to the following table for common issues and their potential solutions. Always disconnect power before troubleshooting.

If the problem persists after attempting these solutions, contact a qualified service technician or Leeson Electric support.
