Introduction
Before You Start: Warnings and Cautions
WARNING
A warning message describes either a potentially hazardous situation which, if not
avoided, could result in death or serious injury to the operator.
Electrical Warnings
• High voltages are present inside the instrument. Always disconnect the instrument from the
power supply before removing the cover.
• The instrument must be grounded properly.
Chemical Warnings
• Do not use any electrolyte solutions that are not compatible with the materials of construction.
Consult Beckman Coulter, Inc. or its local representative before using any concentrated acids or
alkalis in the instrument.
•
Toxicity, safety, and proper handling procedures for electrolyte and reagents used in particle
and cell analysis should be adhered to at all times. Consult appropriate safety manuals and
Material Safety Data Sheets for the items.
• Care should be taken when mixing or exchanging solutions. Reactions can occur between
incompatible solvents and electrolyte salts, and may be violent.
• Do not use azide and cyanide salts in acid solutions.
•
Flammable electrolyte solutions should be prepared for use in an appropriate environment and
brought to the instrument only when required for an analysis.
Mechanical Warnings
• Do not interfere with or attempt to disable the interlocks incorporated in the door and platform
assembly.
• Do not use force to remove or replace any glass item. In the event of difficulty, consult Beckman
Coulter, Inc. or its local representative.
• Replace an aperture tube empty of electrolyte. Do not attempt to pre-fill a tube before placing
it in the aperture tube connector.
Fire Warnings
•
Many non-aqueous electrolyte solutions are flammable and contain organic salts that can
support or enhance fire. Where possible choose less flammable alternatives.
•
Prepare and filter flammable solvents and electrolyte solutions away from the Multisizer 4,
preferably under a suitable fume hood. Extinguish all open flames in the vicinity and observe
normal precautions against ignition by hot surfaces or electrical sparks.
