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 inlet and outlet connections (1 in. NPT standard)
• Use recommended air pressure (20–100 psi, depending on configuration)
• Check for leaks and secure all fittings before operation
• Follow manufacturer guidelines for diaphragm and seat replacement intervals
• Regularly inspect for wear and replace consumable parts as needed
• Periodically check diaphragms, seats, and balls for wear or damage
• Lubricate moving parts as specified in the manual
• Keep air supply clean and dry to prevent contamination
• Store pump in a clean, dry environment when not in use
