Evacuation
It is required to evacuate the system at 350 microns or less. If a leak is suspect, apply dry nitrogen
to locate it. Repair the leak and repeat the leak test. To verify that the system reports no further leaks,
close the valve that goes to the suction vacuum pump; this will isolate it and will allow you to
sustain the system under a vacuum. Observe the gauge during several minutes. If reading indicates
a stable and continuous increase, it will be indicative of a leak. If the gauge indicates an increase
and after several minutes it stabilizes and remains constant, it will be indicative of a system free
of leaks but still withholding humidity. This situation will require an additional evacuation in the
event of a gauge reading above 350 microns.
