Installation Notes:

• Using genuine GRACO parts ensures optimal performance, safety, and longevity of the pump.
• Read all instruction manuals, tags, and labels before operating the equipment.
• Ensure all connections are secure and compatible with the pump’s specifications.
• Grease lapped surfaces and bores as specified during assembly.
• Torque fasteners to recommended values (e.g., 80 to 100 in-lb for certain components).
• Leave center housing and air covers assembled during certain maintenance procedures unless otherwise specified.
• Regularly inspect diaphragms, balls, and seats for wear.
• Follow recommended lubrication and torque procedures during reassembly.
• Use only compatible replacement parts.
