Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure proper alignment of pump and piping to avoid stress on connections
• Use appropriate thread sealant for BSPT connections
• Check for leaks after installation and during initial operation
• Follow manufacturer’s guidelines for air supply and pressure settings
• Regularly inspect and maintain diaphragms, seats, and balls as per maintenance schedule
• Inspect diaphragms and seats for wear or damage regularly
• Replace worn or damaged components with genuine GRACO parts
• Lubricate moving parts as recommended
• Monitor pump performance and address any unusual noise or vibration promptly
