Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump integrity and void warranties.
• Ensure proper alignment of pump components during assembly
• Use recommended gaskets and seals for leak prevention
• Follow torque specifications for flange and connection tightening
• Regularly inspect diaphragms, seats, and balls for wear and replace as needed
• Refer to the manual for specific installation and maintenance procedures
