Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure proper alignment of pump components during assembly
• Use recommended torque settings for bolts to maintain even sealing pressure
• Inspect diaphragms and seats regularly for wear and replace as needed
• Follow manufacturer guidelines for air supply and fluid connections
• Regularly check for leaks and maintain clean fluid paths
• Perform routine inspections of diaphragms, balls, and seats
• Replace worn components with genuine GRACO parts
• Keep air supply clean and dry to prevent valve issues
• Lubricate moving parts as recommended by the manufacturer
