Filter Condition Evaluation
To test the condition of the filter cartridge, turn the unit on high
speed and observe the output airflow of the unit. When the filter
cartridge becomes clogged with particles there will be a notice-
able drop in air flow and the air output will no longer be steady.
Additionally, the indicator ball will be hovering in the upper region
of the flow meter (figure 2, LC0760 & LC1060).

of the HEPA filter cartridge. Insert it in the unit
with the foam tape of the filter pressing
against the carbon filter (figure 5).
