Service and Maintenance
Nonscheduled Maintenance Procedures
WARNING: Potential Biohazard.
Wear gloves, lab coats, and safety
glasses and follow other biosafety practices as specified in the OSHA
Bloodborne Pathogen Rule (29 CFR Part 1910.1030) or other equivalent
biosafety procedures.
Shear Valve Cleaning
Cleaning of the Shear Valve ensures accurate and precise performance. Any
reagent or blood residue may cause the valve to leak or function improperly. The
shear valve assembly is depicted in Figure 9.10.
The shear valve is made of a ceramic material and consists of three separate
sections — front, center and rear. The rear and front sections are connected to the
CELL-DYN 3200 by tubing that should not be removed.
NOTE:
The center section is not connected by tubing and must be handled
carefully, as it will break if it is dropped. Care should be taken to avoid
chipping, scratching or otherwise damaging any of the sections.
