Ozone inhalation hazard. Under certain conditions, this instrument
produces ozone concentrations above safe exposure limits. Plumb
waste gases to a fume hood or to the building exterior in accordance
with local, regional and national requirements.
This instrument is rated for an altitude of 2000 m (6562 ft) maximum.
Use of this instrument at an altitude higher than 2000 m can slightly
increase the potential for the insulation to breakdown, which can result in
an electric shock hazard. The manufacturer recommends that users with
concerns contact technical support.
Put the instrument in a position that makes it easy to disconnect the
instrument from the power source.
Put the instrument in a position so that the fan ventilation opening on the
left side is not blocked. Do not allow the power cord to contact hot
surfaces on the QC8500 measurement channels.
There are two placement options:
• Put the instrument on top of the QuikChem System Core
Make sure that the heater controller is on the left side of the system.
• Put the instrument below the peristaltic pump if the space on top of
the QuikChem system is not available. The peristaltic pump is located
on the left side of the QuikChem system.
