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 ports
• Use appropriate thread sealant for NPT connections
• Check air supply for correct pressure and cleanliness
• Inspect diaphragms and seats for wear before installation
• Follow manufacturer’s torque specifications for assembly
• Regularly inspect diaphragms, balls, and seats for wear or damage
• Replace worn components with genuine GRACO parts
• Keep air supply clean and dry to prevent valve issues
• Lubricate moving parts as specified in the manual
• Monitor pump for leaks or unusual noise
