Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump. Non-genuine parts may compromise reliability and void warranties.
• Install the pump as close as possible to the material source to maximize 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 ensure leak-free operation
• Rotate the center manifold to change the orientation of inlet or outlet ports as needed
