1.7 SERVICING
Before servicing, remove all power. If it becomes necessary to perform diagnostic service with certain
areas of the machine powered, only qualified personnel should perform the service. Follow all normal
industrial safety practices when dealing with electrical systems. Review and understand the electrical
schematic before attempting any electrical diagnostic service.
Extensive electrical grounding has been provided throughout the machine to reduce shock and explosion
hazards. If any ground wire is found to be damaged or disconnected, do not operate the machine until
this condition has been corrected.
CAUTION: Unless service is being performed by qualified and authorized personnel, close
all access panels to the 2010 cabinet whenever the machine is powered.
1.8 NITROGEN
Nitrogen is a colorless, odorless, and tasteless gas that makes up about 78% of the atmosphere.
WARNING: Nitrogen can cause rapid asphyxiation and death in confined, poorly
ventilated spaces. Nitrogen as a liquid or cold gas may cause severe frostbite to the eyes or
skin. Do not touch frosted pipes or valves. If exposure occurs, restore tissue to normal body
temperature (37°C/ 98.6ºF) as rapidly as possible, followed by protection of the injured
tissue from further damage and infection. Call a physician immediately. Rapid warming of
the affected part is best achieved by using water at 42°C/108ºF. Under no circumstances
should the water temperature be over 44°C/112ºF, nor should the frozen part be rubbed
either before or after re-warming. The patient should not smoke or drink alcohol. Keep
warm and at rest.
KEEP THE EQUIPMENT AREA WELL-VENTILATED.
Nitrogen cannot be detected by the human senses and will be inhaled like air. If adequate ventilation is not
provided, this gas may displace normal air and develop a life-depriving atmosphere without warning. If there
is doubt about the adequacy of the ventilation, use an oxygen analyzer with a 0 to 25% scale to check for
oxygen. Any atmosphere that does not contain enough oxygen for breathing (at least 18%) can cause
dizziness, unconsciousness, or even death. Store containers outdoors or in other well-ventilated areas. Never
enter a tank, pit, or other confined area where these gases may be present until the area is purged with air and
tested for a breathable atmosphere (of at least 18% oxygen) using a gas analyzer.
Liquid Nitrogen Is Extremely Cold. COVER YOUR EYES AND SKIN.
WARNING: Accidental contact of liquid or cold gas with the eyes or skin may cause
severe frostbite. Handle liquid carefully to avoid a splash or spill. Protect your eyes with
safety goggles or a face shield, and cover skin to prevent contact with the liquid, cold gas,
or with cold pipes and equipment. Protective gloves without gauntlet that can be quickly
and easily removed and long sleeves are recommended for arm protection. Wear cuffless
trousers outside boots or over high-top shoes to shed spilled liquid.
Consult with your supplier for safe disposal and other safety information concerning the use and handling of
Liquid Nitrogen.
