Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and void warranties.
• Ensure proper alignment and secure mounting of the pump
• Verify electrical supply matches pump specifications (200-240 VAC, 1Ph)
• Use appropriate tri-clamp fittings for inlet/outlet connections
• Follow local electrical and safety regulations, especially in hazardous locations
• Regularly inspect and maintain fluid path components for wear and contamination
• Periodically check diaphragm, ball, and seat for wear or damage
• Clean and inspect fluid path components as recommended by GRACO
• Monitor pump performance and address any unusual noise or vibration promptly
• Consult the equipment manual for detailed maintenance schedules and procedures
