Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment, reducing the risk of leaks, downtime, and premature failure.
• Ensure all connections are secure and use appropriate thread sealant for NPT ports
• Check for proper alignment and support to prevent stress on pump components
• Follow manufacturer guidelines for air supply and pressure settings
• Regularly inspect diaphragms and seals for wear and replace as needed
• Keep the pump and surrounding area clean to prevent contamination
• Perform routine inspections of diaphragms, seals, and valves
• Use only recommended replacement parts for repairs
• Monitor air consumption and fluid output for signs of wear or inefficiency
• Clean the pump after use with compatible fluids to prevent buildup
