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
Follow torque instructions for manifold assembly to prevent leaks
Regularly inspect and maintain diaphragms, seats, and balls for wear and replace as needed
