Installation Notes

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