1.
Male flare pump intake. Tethered cap
stays with unit. Large diameter hose
suggested for maximum pull down.
2.
Additional intake ports.
3.
Vacuum gauge shows evacuation
progress down to 30” range, so you will
know when to turn on electronic gauge
for more precise reading.
4.
Gas ballast valve (not shown) helps
remove moisture and other con densable
vapors that have been drawn into the
pump as a result of evacuation.
5. Opening the ballast allows fresh air to
enter the cartridge and keep vapors
from combining with the oil. Vapors
escape harmlessly through the exhaust
valve. If combined with oil, vapors can
turn the oil milky white and lower pump
performance below specifica tions.
6. To operate ballast, turn the valve
counter-clockwise one full turn after
evacuation starts. As the vacuum
reading reaches 1000-2000 microns,
close the ballast to achieve a higher
vacuum range.
