Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with existing equipment.
• Ensure proper alignment and secure mounting of the pump
• Connect air supply within the specified pressure range (30–100 psi, 2.1–7 bar, 0.21–0.7 MPa)
• Use appropriate fittings and hoses for fluid and air connections
• Follow manufacturer guidelines for diaphragm and ball replacement intervals
• Regularly inspect for leaks and wear, especially in harsh environments
• Periodically check and replace diaphragms and balls as needed
• Clean pump internals to prevent buildup of solids or contaminants
• Lubricate moving parts according to manufacturer recommendations
• Monitor air consumption and pump performance for early detection of issues
