Installation Notes:
- Using genuine GRACO parts ensures optimal performance, reliability, and safety. Non-genuine parts may compromise pump integrity and void warranties.
- Ground the pump and all equipment in the pumping area to reduce the risk of static sparking
- Install a fluid drain valve near the fluid outlet
- Install a shutoff valve in the fluid outlet line
- Ventilate pump exhaust air to a remote area if contaminants could affect the fluid supply
- Use a bleed-type master air valve to relieve trapped air between the valve and the pump
- Regularly inspect diaphragms, balls, and seals for wear
- Service the air valve externally without uninstalling the pump
- Follow manufacturer guidelines for cleaning and replacement intervals
