Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure proper alignment and secure mounting of the pump
• Use appropriate fittings and hoses for the intended fluid and pressure
• Follow all safety guidelines for compressed air and fluid handling
• Regularly inspect and maintain diaphragms, seats, and balls for wear
• Periodically check for leaks and tighten connections as needed
• Replace worn or damaged diaphragms and seals promptly
• Keep air supply clean and dry to prevent valve and diaphragm issues
• Consult the manual for specific maintenance intervals and procedures
