Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety, and maintains warranty coverage.
• 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 and a shutoff valve in the fluid outlet line
• Follow torque instructions for manifold installation and removal
• Ensure the equipment is properly grounded to prevent static sparking
• Regularly inspect diaphragms, seats, and seals for wear or damage
• Follow manufacturer’s recommended maintenance schedule
• Use only genuine replacement parts for repairs
