Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure all connections are tight and leak-free before operation
• Use appropriate thread sealant for NPT connections
• Follow GRACO’s recommended maintenance schedule for diaphragm and valve inspection
• Install in a location with adequate ventilation and access for maintenance
• Check for proper alignment and secure mounting to prevent vibration
