Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Install the pump as close as possible to the material source to minimize suction requirements and maximize performance
• Use grounded, flexible fluid hoses to reduce the risk of static sparking
• Install a fluid drain valve near the fluid outlet
• Install a shutoff valve in the fluid outlet line
• Remove and rotate the center manifold(s) to change the orientation of inlet or outlet port(s) as needed
• Follow torque instructions for proper assembly and leak prevention
• Regularly inspect diaphragms, balls, and seats for wear and replace as needed
• Ensure all connections are tight and free from leaks
• Keep the pump and surrounding area clean to prevent contamination
• Follow manufacturer guidelines for lubrication and servicing intervals
