CORRECTIVE ACTION
Organic sensor has detected filter
breakthrough and only 5-10% of filter life
remains. Replace filters with a spare set of
filters stored. Consult Chapters 3, 4, and 5,

filter life based on specific chemical use. All
chemicals have different life. Always limit
chemical use, cover up chemicals and turn
off blower when not in used to preserve life.
Replace carbon filter.
