A
WARNING
CONTAMINATION HAZARD
Wear NIOSH-approved
protective gear when
changing filters.
Change filters after
every rennediation job.
Change HEPA filter when the filter
indicator
li ght comes on.
Dispose of used filters according to
your local regulations.
Read and understand manual
before use.
Loosen 318"
bolt
hex head
Latch
Once the bolt
is loose slide
the latch out-
ward.

READ AND SAVE THESE INSTRUCTIONS
OPERATING INSTRUCTIONS
Setup
t 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 5520 standards, 10.3.t See
this manual's "Resources' section (pg.5) for how to get an 5520 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 NEPA 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 NEPA 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
HERA 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.
