maintaining or servicing your equipment, as well as to contact
you in case we have important safety information concerning
this product. If you determine service is required, have your
equipment model, serial number and original proof of purchase
available and call your distributor for assistance with obtaining
a return material authorization (RMA).
ELECTRICAL SAFETY
The HEPA 500 has two features designed to protect the
machine and the operator from electrical hazards.
1. Circuit Breaker. The On/Off switch incorporates a circuit
breaker to protect the machine from excessive electrical
current by automatically turning the unit off when more than 12
amps run through the unit's circuitry. If the circuit breaker trips,
first reduce the number of units connected to the main unit via
"daisy chain," then press the On/Off switch to reset.
2. GFCI. The HEPA 500 is also equipped with Ground Fault
Circuit Interrupter (GFCI). The GFCI helps to protect the user
against electric shock. If the system detects a ground fault, the
GFCI will instantly interrupt the electric current. The GFCI will
also trip when a short circuit or an overload occurs.
NOTICE: If the GFCI trips, unplug the unit, and look for
potential electrical hazards – standing water, worn or frayed
cords – anything that would cause a surge of electrical current.
Once you've addressed these problems, press the red "Reset"
button and check for proper operation. To isolate the problem,
it may be useful to relocate the unit and plug it into a different
outlet. If the GFCI continues to trip after you've addressed any
obvious problems, please contact your Dri-Eaz distributor for
assistance.
HEPA 500 APPLICATIONS
Water Damage
Use of the HEPA 500 within the affected area will reduce
particle levels during the restoration process. In a standard
Category 1 water damage situation, place the HEPA 500 in
the middle of the affected area. Category 2 and 3 water
damage situations may require negative pressure
containment and other precautions. Only professionals with
the appropriate training should use containment
techniques.
Mold Remediation
Most mold remediation projects require containment.
Containment prevents the spread of mold spores and other
bioaerosols. Always use the optional DOP Filter (F415)
when using the HEPA 500 to ensure first-pass filtration in a

containment setup. Only a professional with the appropriate
training should attempt mold remediation.
Odor control
When used with the optional Activated Carbon Filter (F397),
the HEPA 500 can effectively remove many odors from an
indoor air environment, including volatile organic compounds
(VOCs), food odors, fumes from paint and paint thinners,
sewer odors, and many others.
Other uses include fire damage restoration, dust control, odor
control and sewage remediation. These are specialized
applications and require professional training. For more
information about using the HEPA 500 in these situations,
consult the IICRC S520: The Standard and Reference Guide
for Professional Mold Remediation. You can get a copy from
the IICRC at 360-693-5675 or visit their website at
www.IICRC.org. You can also contact Restoration Sciences
Academy at 800-932-3030 for technical advice and to learn
more about RSA classes.
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.
