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 maximize suction and performance
• Minimize suction requirements to enhance pump efficiency
• Use grounded, flexible fluid hoses to reduce static sparking risk
• Install a fluid drain valve near the fluid outlet and a shutoff valve in the outlet line
• Follow torque instructions for manifold assembly to prevent leaks
• Regularly inspect and maintain diaphragms, seats, and balls for wear
