Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and compatibility with GRACO equipment.
• Install a bleed-type master air valve (required)
• Use electrically conductive air supply and fluid supply lines
• Install a fluid drain valve (required)
• Ensure proper grounding with a ground wire (required)
• Use an air line filter and regulator for optimal performance
• Vent exhaust air to a safe location or use a remote air exhaust container
• All wetted and non-wetted pump parts must be compatible with the fluid being pumped
• Regularly inspect and service air valve and ball checks
• Check for leaks and ensure all connections are secure
• Follow manufacturer’s guidelines for fluid compatibility and temperature limits
• Replace worn or damaged parts with genuine GRACO components
