Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment. Non-genuine parts may compromise safety and efficiency.
• Ensure proper alignment of inlet and outlet connections (1-1/2" NPT or BSP or ANSI-Flange)
• Check air supply for correct pressure and cleanliness
• Inspect diaphragms and balls for wear before installation
• Follow manufacturer’s torque specifications for all connections
• Regularly inspect and maintain air valve and ball checks for optimal performance
• Use only compatible fluids as specified by GRACO
• Perform routine maintenance as outlined in the manual
• Store spare diaphragms and balls for quick replacement
• Monitor pump speed and pressure to avoid overloading
