Installation & Maintenance Notes

• Before installing, make sure the system is depressurized and all components are clean and free of debris.
• When reassembling, align the packing carefully to avoid pinching or misalignment that could cause leaks.
• Inspect packing regularly; replace if worn, compressed, or damaged to maintain reliable sealing and pump performance.
• Use only genuine OEM packings to ensure correct tolerances and durability — aftermarket packings may compromise sealing or cause premature wear.
