The vacuum gauge will be broken if a
positive pressure is applied to it.
As such, when the evacuation work is
completed, disconnect the hose which is
connected to the positive pressure side.
The vacuum gauge may malfunction or fail
if it is dropped or subjected to vibration.
If this gauge has been dropped or knocked
into something, immediately inspect it for
damage, cracks and deformation.

such areas, make repairs, and resume the evacuation.
