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 during installation
• Use appropriate thread sealant for NPT connections to prevent leaks
• Verify air supply is clean and dry to avoid contamination and valve malfunction
• Follow torque specifications for bolted joints to ensure even sealing pressure
• Regularly inspect diaphragm and seals for wear and replace as needed
