Use and Operation
INTRODUCTION
The DefendAir®HEPA 500 is a portable filtration system that draws air in from the
surrounding environment and passes it through an advanced filtration system. The
unit removes airborne particles like dust, mold spores, pollen, pet dander and mis-
cellaneous debris.
HOW THE DEFENDAIR®HEPA 500 WORKS
The HEPA 500 uses an efficient mix of airflow and filtration to create “cleaner” air.
The unit’s maximum 500 CFM motor draws air into two types of filters--a pre-filter
and a HEPA filter. The first stage of filtration captures larger particles, and the sec-
ond stage of filtration captures much smaller particles down to 0.3 microns.
What makes the Dri-Eaz DefendAir HEPA 500 unique is its Clean Air Delivery Rate
(CADR) capability. CADR is an Association of Home Appliance Manufacturers’
(AHAM) rating that tells you how efficiently the machine and filter work together to
remove particles from the air at the airflow rate you’re using.
You can use the DefendAir HEPA 500 for mold remediation and/or water damage
restoration. The unit is not intended for asbestos remediation.

OPERATING INSTRUCTIONS
Setup
1. Unwrap the cord wrap completely
2. Place the HEPA 500 upright (vertical with handle at the top)
3. Plug in to a standard 115 volt outlet. Each HEPA 500 needs 3 amps to operate.
4. To switch the unit on, locate the control panel and turn the variable speed switch
clockwise to start the unit (see “Control Panel” below). Then select
either a maximum (500 CFM) or down to a minimum (250 CFM) airflow rate. To
maintain the optimal CFM, consult the IICRC S520 standards, 10.3.1. See
this manual’s “Resources” section (pg.5) for how to get an S520 standards guide.
5. The HEPA 500 is multi-positional. For more information, see “Specialized
Features” on (pg. 4).
The Control Panel
Variable Speed Control
Note that the MAX setting is located immediately left of the OFF button, and the MIN
setting requires an almost 360 degree clockwise turn.
Change Light
The change light illuminates when you need to change the HEPA filter.
The Auxiliary Outlet
You can “daisy chain” or interconnect up to 3 HEPA 500’s to customize your air filtra-
tion needs. The unit can conduct a maximum of 12 amps when it is turned off, and 9
amps when it is turned on. That means you can plug other equipment into the unit,
but the amperage is limited.
Red Circuit Breaker Switch
The primary purpose of the circuit breaker is to protect the machine. It turns the unit
off when more than 12 amps run through the on-unit circuit.
Ground Fault Circuit Interrupter (GFCI)
The GFCI helps protect the user should it detect a sudden “ground fault,” the GFCI
will interrupt the electric current. The GFCI will also trip when a short circuit or an
overload occurs.
When the GFCI “trips,” unplug the unit, and look for potential hazards standing
water, frayed cords, etc. anything that would cause a surge of electrical current.
Relocate the unit and plug it into a different outlet. Then push the “reset” button, and
check to see if it’s operating; if so, continue use, if not call a Dri-Eaz Technical
Specialist at 800-575-5152.
The Filters
About the filters
The HEPA 500 utilizes a 2-stage filtration system designed with the most advanced
HEPA filtration technology available. The first stage utilizes a pre-filter (Figure 3), and
the second a HEPA filter (Figure 4). The pre-filter captures larger particles, and the
HEPA filter captures 99.97% of smaller particles down to 0.3 microns.
For environments with a high volume of aerosolized particles, you can use 2 prefilters
to extend the life of the HEPA filter. See “Maintenance” for how often to replace filters.
Changing filters
1. With a 3/8" wrench, loosen the 8 latches holding the inlet panel in place. See
Figure 2.
2. Slide the latches outward, away from the center of the inlet panel.
3. Remove the inlet panel.
4. Remove used filters and replace.
See “Maintenance” for how often to replace filters.

APPLICATIONS FOR THE DEFENDAIR HEPA 500
Primary Uses
The primary uses for your DefendAir HEPA 500 are:
• Water damage restoration
• Mold remediation (including creating a negative air environment)
Other uses include fire damage restoration, dust control, odor control and sewage
remediation. To learn more about these, contact a Dri-Eaz Technical Specialist at 800-
575-5152.
Use for Water Damage
In a standard Category 1 water damage situation, place the DefendAir HEPA 500 in
the middle of the affected area. Utilize airmovers to lift particles into the air. The HEPA
500 filters the air in the affected area to reduce particle levels during the restoration
process.
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 pro-
fessional 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 [phone]. You can also contact the Dri-Eaz
Education Department for technical advice or to learn more about educational opportu-
nities at 800-575-5152.
Specialized Features
Daisy-chain capability
Dri-Eaz designed the HEPA 500 for optimal versatility. You can interconnect up to
three units to create a maximum of 500, 1000, or 1500 CFM using the auxiliary outlet
on the unit’s control panel. You can also daisy chain the units in a stacked position
(see “multi-positional” in this section).
Removable intake panel for remediation professionals
The DefendAir HEPA 500 has a specialized feature to assist containment (Figure 6).
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.Install the HEPA 500 outside the containment 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

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.
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,” Removable intake
panel for remediation professionals).
WARNING
BREATHING HAZARD
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.

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 7). You can also
stack them horizontally for space-
saving storage, or operate a unit
with its outlet facing upward.
