Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and longevity of the pump, reducing downtime and maintenance costs.
• Install a fluid pressure relief valve at the pump outlet to prevent overpressurization and rupture of the pump or hose (recommended part: GR238428)
• Ensure proper alignment and secure mounting of the pump
• Use compatible hoses and fittings rated for the intended fluid and pressure
• Regularly inspect diaphragms and seals for wear and replace as needed
• Follow GRACO’s recommended maintenance schedule for best results
