Installation Notes
  1. Clean the accumulator housing thoroughly before installation to remove oil, grease, and debris.
  2. Install the diaphragm with the sealing lip facing the nitrogen side; ensure the sealing surface is scratch-free.
  3. Charge nitrogen per equipment specs (typically 120–150 bar); avoid overpressure.
  4. Inspect regularly for aging/cracking to prevent nitrogen leaks and weak impact performance.
