Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Ensure proper alignment of inlet and outlet connections
• Use appropriate thread sealant for NPT connections
• Check air supply for correct pressure and cleanliness
• Inspect diaphragms and balls for wear before installation
• Follow manufacturer’s torque specifications for bolted connections
• Regularly inspect diaphragms, balls, and seals for wear or damage
• Lubricate moving parts as recommended
• Clean pump internals after handling corrosive or abrasive fluids
• Replace worn components with genuine GRACO parts
