This machine is not suitable for use with volatile or
flammable liquids!
This Barrett machine is
not
equipped for use in hazardous locations as defined by the National
Fire Protection Association (NFPA). NFPA guidelines designate locations that may be
hazardous due to ignitable atmospheres caused by generation of vapors from flammable or
combustible liquids. During operation, friction within the centrifuge may bring some surface
temperatures above the flash point of Class I and Class II Liquids (over 140 degrees F) thereby
creating an ignitable atmosphere within and around the machine. For this reason
no fluid
classified by NFPA as Flammable (Class I) or Combustible (Class II) should be used in
this machine. Such use may cause a flash fire or explosion resulting in serious
personal injury and/or property damage.
For more information see NFPA 70 (the National
Electrical Code) and NFPA 30.
Modifications to programmable equipment should be
made by authorized and qualified personnel only!
This machine is equipped with a programmed logic controller (PLC) and, possibly, a variable-
speed drive (VFD). Altering or tampering with the settings that are programmed into these
devices could cause the machine to malfunction. It could also lead to failure of the safety
controls and devices meant to protect personnel and change the motor speed that could
severely damage the machine.
Only qualified personnel should attempt to change the settings.
Before attempting any
alterations
we strongly urge that you contact Barrett Centrifugals Inc. to discuss any
changes that you are considering or desire.
