Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Install a fluid pressure relief valve at the pump outlet to prevent overpressurization and rupture of the pump or hose
• Ensure proper alignment and secure mounting of the pump
• Use appropriate fittings and hoses for the intended fluid and pressure
• Regularly inspect and maintain diaphragms, balls, and seals for wear and leaks
