Configurations," p. 4, for details.
Filters should be replaced whenever they show visible
accumulation of dust. For environments with a high volume of
aerosolized particles, we recommend the use of two prefilters
to extend the life of the HEPA filter.
Always replace the HEPA filter promptly when the Filter
Change Light illuminates. Do not attempt to vacuum and reuse
the HEPA filter.
NOTICE: When using the HEPA 500 on remediation
projects, the filters should be changed and properly
disposed of after every job.
Replacement filters are available from your Dri-Eaz
distributor.
MAINTENANCE
WARNING
WARNING! ELECTRIC SHOCK HAZARD.
Disconnect from electrical supply prior to servicing
or cleaning.
WARNING! BREATHING HAZARD. Always wear
an appropriate NIOSH-approved respirator and
personal protective equipment when removing or
replacing filters, or when cleaning the HEPA 500.
Before each use
1. Inspect the electrical cord for damage, and do not use the
unit if you find any fraying, cuts, etc. Contact your local Dri-Eaz
distributor for service.
As Needed
Clean housing and impeller. Lay the the unit on its back and
loosen the four filter cover clamps (Fig. 2). Lift off the filter
cover and remove any prefilters present. Use a 3/8 in. wrench
to loosen the 8 retaining tab nuts holding the inlet panel in
place. Slide the retaining tabs outward away from the center of
the inlet panel, and lift off the inlet panel.
Always replace the HEPA filter promptly
when the Filter Change Light illuminates. Do
not attempt to vacuum and reuse the HEPA
filter.
Filters
The prefilters should be inspected regularly
and changed whenever dust has visibly
accumulated on the filter surface.
The HEPA filter should be changed
whenever the change filter light comes on.
See "HEPA 500 Filter Configurations," p. 4,
for the available filter combinations.

Remediation applications
• Wear NIOSH-approved protective gear when changing filters.
• Change filters after every remediation job.
• Change HEPA filter when the filter indicator light comes on.
• Dispose of used filters according to local regulations.
• Replace both the prefilters and HEPA filter 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.
Filter access instructions
To inspect and change the prefilters, lay the unit flat on its
back. Lift and release the four latches on the outlet panel and
lift off the panel. Inspect and/or replace the prefilters as
necessary.
After ensuring that the prefilter(s) are properly seated, replace
the outlet panel, and re-engage the latches. The HEPA 500 is
now ready to return to service.

After making sure that the filter is properly seated, replace the
inlet panel, slide the tabs back into place, and tighten the nuts.
Do not overtighten. The HEPA 500 is now ready to return to
service.
About DOP first-pass filtration efficiency
DOP (Dispersed Oil Particulate) first-pass efficiency refers to a
standard procedure for testing the effectiveness of HEPA
filtration. The DOP test introduces a dense cloud of extremely
fine particulates into the filter under controlled conditions. DOP
verification is required in certain settings.
The addition of the DOP filter (F415) makes the HEPA 500 a
high efficiency three-stage air filtration unit suitable for any job
