Once the grip seal bags are placed in the chamber filled with water and the lid is securely shut, the control unit will be activated to remove air from the chamber until a specific vacuum level is achieved. If there is a minor leakage, the gas inside the grip seal bags will escape. The leak will be revealed by the rising bubbles of gas at the point of leakage. This occurrence of gas bubbles flowing can frequently be observed without any visual aid.
