PREVENTIVE MAINTENANCE AND SAFETY
4.2 Cleaning and Decontamination Procedures
Cleaning the Case Exterior and Lid
Cleaning these surfaces requires care to avoid damage. Never use abrasive powdered
cleaners, or solvents as described previously.
WARNING!
Disconnect the instrument from line power before cleaning with liquids.
1 Wipe surfaces with warm soapy water. Further sterilization can be done with
household bleach or a 2 percent glutaraldehyde solution.
CAUTION:
Do not pour or spill liquid into the instrument bowl. If liquid spills over the drive hub
base, it can cause serious damage to the drive motor or electronics.
Cleaning the Instrument Bowl and Inner Lid
If you observe or suspect that sample fluid has contacted any of these surfaces:
1 Wipe the surface clean using soap and warm water.
2 Disinfect as required for the particular substance. See further information in
this section.
3 Remove all moisture from the instrument bowl.
Chemically Disinfecting the Rotor
To chemically disinfect for Human Immunodeficiency Virus (HIV) or Mycobacterium
tuberculosis:
1 Spray with diluted (1/256 x 30 mL/gallon of water) Vesphene II SE* or some
other intermediate level disinfecting detergent and soak for at least 20
minutes.
2 Remove detergent by thoroughly rinsing with tap water.
3 If sporicidal sterilization is required, follow the above disinfectant with 2%
alkaline activated glutaraldehyde for 10 hours.
4 Completely remove all chemical solutions with water before reusing the rotor.
5 Wipe the rotor dry.
* Vesphene II SE is a product of STERIS Corporation.
NOTE: This procedure is not considered effective against Creutzfeldt-Jakob Disease
virus (CJD).
