Preface
CAUTION
Contains Parts and Assemblies
Susceptible to Damage by
Electrostatic Discharge (ESD)
Important Read this instruction manual. Failure to read, understand and follow instructions in this manual may
result in damage to the unit, injury to operating personnel, and poor equipment performance.
Caution All internal adjustments and maintenance must be performed by qualified service personnel.
Warning Nitrogen gas can cause suffocation without warning. Store and use liquid nitrogen only in a
well-ventilated place. As the liquid evaporates, the resulting gas displaces the normal air in the area.
(The cloudy vapor that appears when liquid nitrogen is exposed to the air is condensed moisture, not
the gas itself. The issuing gas is invisible.) In closed areas, excessive amounts of nitrogen gas reduces the
concentration of oxygen and can result in asphyxiation. Because nitrogen gas is colorless, odorless, and
tasteless, it cannot be detected by the human senses. Breathing an atmosphere that contains less than
19.5% oxygen can cause dizziness and quickly result in unconsciousness and death. Therefore, the use
of oxygen monitoring equipment is strongly recommended.
Warning Contact of liquid nitrogen with the skin or eyes may cause serious (freezing) injury.
Warning Do not roll. Always keep liquid nitrogen vessel in an upright position. Exercise caution to
prevent spilling and splashing.
