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
• Check air supply pressure and quality before operation
• Inspect diaphragms and balls regularly for wear and replace as needed
• Follow manufacturer’s torque specifications for assembly
