Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and safety, and helps maintain warranty coverage.
• Install a fluid pressure relief valve at the pump outlet to prevent overpressurization and rupture of the pump or hose (GRACO recommends using Fluid Pressure Relief Kit, part number GR238428)
• Ensure proper grounding for acetal models
• Follow manufacturer guidelines for installation and maintenance
• Regularly inspect and service air valve and ball checks for optimal performance
