Mold Remediation
In most cases, the remediation process requires containment of the affected area.
Containment prevents the spread of mold spores and other bioaerosols. Only a
professional with specialized training in remediation and containment techniques
should use the HEPA 500 (or any negative air machine) for remediation. For more
information about proper remediation techniques, consult the IICRC S520: The
Standard and Reference Guide for Professional Mold Remediation. You can get a
copy and learn more through the IICRC at (360) 693-5675. You can also contact
the Dri-Eaz Education Department for technical advice or to learn more about edu-
cational opportunities at 0800-542-9609.
Formally trained remediation professionals
Run the HEPA 500 as a negative air machine without interruption for the
duration of every remediation job. The HEPA 500 filters 99.97% of particles
0.3 microns and larger, such as mold spores and fungi.
When using the HEPA 500 in a containment area, turn off all sources of
power to open combustion appliances such as fireplaces, boilers, furnaces,
water heaters and HVAC systems to avoid the risk of backdrafting deadly
carbon monoxide fumes.
If the Filter Change Light illuminates during the remediation process, imme-
diately change the HEPA filter. See "Changing Filters" and "Maintenance" for
more information.
To create a negative air environment
You can install the DefendAir HEPA 500 outside a containment area to draw
air out of an affected area. (See Specialized Features below.)
Specialized Features
Removable intake panel for remediation professionals
The DefendAir HEPA 500 has a specialized feature to assist containment (Figure
7). There's a removable panel on the intake side of the unit. Lift the 8 latches to
release the panel as shown in Figure 3
ment area to draw air out. Cut a hole in the containment plastic the size of the
unit's inlet, insert the inlet into the plastic, and seal the circumference tightly with
duct tape (no air should be able to pass through). A tightly sealed containment area
will aid in creating an effective negative pressure. Use a manometer to monitor air
pressure. Manometers are available at most equipment supply houses.
Multi-Positional
You can stack and operate up to two HEPA 500s vertically. The handle of one unit
fits into bottom of another unit (see Figure 6). You can also stack them horizontally
for space-saving storage, or operate a unit with its outlet facing upward.
