is no refrigerant left in the system. When using the oxygen-free nitrogen end-charge,
the system must be vented to atmospheric pressure to allow for work. This operation is
absolutely vital if brazing operations are to take place on pipes.
- Ensure that the vacuum pump outlet is not near any source of ignition and that ventilation
is available.
