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 (1.5-inch NPT or BSP or ANSI flange)
• Use appropriate thread sealant for leak-free installation
• Verify air supply is clean, dry, and within specified pressure range (up to 120 psi)
• Regularly inspect and maintain air valve and diaphragm for optimal performance
• Follow all safety guidelines and local regulations during installation and maintenance
