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
• Use appropriate thread sealant for NPT connections
• Verify air supply is clean and dry to prevent valve and diaphragm damage
• Follow manufacturer’s torque specifications for all fasteners
• Regularly inspect diaphragms, balls, and seats for wear and replace as needed
• Periodically check for leaks and tighten connections as necessary
• Inspect and clean air filter regularly
• Replace worn diaphragms and seals promptly
• Lubricate moving parts as recommended by the manufacturer
