WARNING
CONTAMINATION HAZARD
• Inspect pre-filter before each use. Look for accumulated dust and dirt
that could restrict airflow through the filter into the unit. If any is visible,
change out the pre-filter.
• Replace the HEPA filter when the Change Indicator Light comes on.
Note:To be assured of true HEPA filtration, change the HEPA filter after
every water damage job, or when the indicator light comes on; whichever
occurs first.
• Replace both the filters to prevent cross-contamination.
• Clean the unit thoroughly (vacuum and damp wipe per IICRC S520,
10.11) after each job before removing it from the containment area to
avoid cross-contamination. Pay particular attention to the area around
the air intake. Let the unit dry before installing clean filters.
