Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump integrity and void warranties.
• Ensure all fluids and solvents are chemically compatible with the wetted parts (stainless steel and PTFE)
• Never move or lift the pump under pressure; always follow pressure relief procedures before handling
• Have two people lift the pump by grasping the outlet manifold securely due to its weight
• Consult the equipment manual for detailed installation and maintenance instructions
