Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the equipment. Non-genuine parts may compromise system reliability and void warranties.
• Mount fluid pressure gauges at proportioning pump inlets to monitor and adjust feed pump pressures
• Never exceed 25% of the Hydra-Cat pump outbound fluid pressure on the feed supply
• Label all pumps, hoses, and regulators to indicate resin or hardener side
• Follow manufacturer guidelines for air supply and fluid feed setup
• Ensure proper grounding and use recommended filters and regulators
• Regularly inspect wetted parts for wear and replace as needed
• Keep air and fluid lines clean and free from contaminants
• Follow recommended lubrication and maintenance schedules
• Consult the manual for specific maintenance procedures
