In many cases, safety information is displayed on the instrument itself. The safety label
illustrations in the documentation that came with your instrument show the locations of the
safety labels. Should any of these labels become loose or unreadable, use the information in
the front of this manual to contact us to obtain new ones.
Fire Safety and Burn Hazards
The following symbols may appear inside the instrument to warn you about hot surfaces in
the vicinity of the symbol.
To avoid a burn injury and the risk of fire or explosion, follow these guidelines:
• Do not test flammable or explosive samples.
• Use only nitrogen or dried air to purge your instrument.
• Do not touch the infrared source housing; it may be very hot.
• Do not place anything on the electronics cover.
• After you turn off your instrument, wait 10 minutes before you replace components.
• Never block any of the vents on an instrument or its power supply.
• Use exact replacements for power supplies.
The following precautions provide additional information about fire safety and preventing
burn hazards.
WARNING
Before opening the desiccant compartment, turn off the instrument power,
unplug the power cord and remove all accessories and samples from the system. Entry of
flammable liquids or gases into the desiccant compartment is an explosion hazard. If such
entry occurs, contact us immediately and do not apply power to the instrument until the
condition has been corrected.
CAUTION
The infrared source in your instrument can be removed without removing the
main cover of the instrument. If you remove the source, follow the provided instructions
and be aware that the source housing may be very hot and stays hot for up to 10 minutes
after you turn off the instrument. To avoid being burned or starting a fire, do not touch
the source with your body or any flammable object until it has cooled.
