Due to differences in water quality, steam quality, frequency of use
and boiler additives, no specific frequency interval is recommended
for chamber cleaning. Operators must determine appropriate
cleaning interval based on the local water conditions and chamber
appearance.
Chamber cleaning should be performed:
• When spills or other soiling have occurred in the chamber
• Periodically to maintain sterilizer cleanliness and appearance
• When processing materials that may be detrimental to the
sterilizer (e.g., chloride-containing substances)
1. If applicable, the shelf assembly must be removed before
cleaning the chamber.
