Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump efficiency and longevity.
• Ensure proper alignment and secure mounting to prevent vibration and leaks
• Use appropriate fittings and hoses rated for the intended fluid and pressure
• Follow all safety instructions and local regulations during installation
• Regularly inspect and maintain the pump, especially the diaphragm and air valve, for optimal performance
• Regularly check and clean the air valve and diaphragm
• Replace worn or damaged parts with genuine GRACO components
• Monitor for leaks and unusual noises during operation
• Refer to the manual for specific maintenance intervals and procedures
