Installation Notes

1. Thoroughly clean the accumulator housing before installation, removing all oil, grease, and debris.
2. Install the diaphragm with its sealing lip facing the nitrogen side, ensuring the sealing surface is free of scratches.
3. Charge the nitrogen pressure according to the equipment specifications (typically 120–150 bar); avoid over-pressurization.
4. Regularly inspect for aging or cracking to prevent nitrogen leaks that could cause weak impact performance.
