discolored, or if it is contaminated with debris or foreign particles, replace the filter.
NOTICE We recommend maintaining seal and desiccation and/or purging the
instrument at all times. Equipment damage due to failure to maintain seal and desiccation
and/or purge is not covered under the warranty.
