Installation Notes:
Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump integrity and void warranties.
Ensure proper alignment of flanges and secure all connections to prevent leaks
Use appropriate gaskets and seals for chemical compatibility
Install air filter/regulator assembly for clean, regulated air supply
Follow manufacturer’s guidelines for maximum pressure and temperature ratings
Regularly inspect diaphragms, balls, and seats for wear and replace as needed
For remote air exhaust, use a grounded air exhaust hose and container as recommended
Perform routine inspections and maintenance as outlined in the manual
Replace diaphragms, balls, and seats at recommended intervals
Keep air supply clean and dry to prevent valve and diaphragm damage
Monitor for unusual noise or vibration, which may indicate wear or misalignment
