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,

contact Dri-Eaz.

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.

and lift off cover to access the HEPA filter.

Change Light

The change light illuminates when you need to change the

HEPA filter.

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 230 volt outlet. Each HEPA 500 needs

1.5 amps to operate.

4. To switch the unit on, locate the control panel and turn the

variable speed switch clockwise (Fig. 1). Then select either a

maximum (500 CFM) or down to a minimum (250 CFM) airflow

rate. To maintain the optimal air change rate, consult the IICRC

S520 standards, 10.3.1.

Special Features

Ducting options

The HEPA 500 has a standard ductable 12 in. inlet and a

ductable 8 in. outlet, suitable for use with rigid and layflat

ducting. See "Ducting Options," p. 4, for descriptions of the

ducting types available from Dri-Eaz.

Negative Pressure Setup

The HEPA 500 can be configured to set up a negative

pressure containment area. Install the HEPA 500 outside the

containment area to draw air out. Only professionals with the

appropriate training should set up negative pressure

containment areas.

Options for Storage and Operation

The HEPA 500 can be stacked up to two high for storage or

operation. The handle of one unit fits snugly into the bottom of

a second unit. The unit can also be operated on its back, with

the outlet facing upward.

For storage, HEPA 500s may be stacked horizontally or

vertically. Secure the unit properly when transporting.

About the filters

The HEPA 500 uses two types of disposable filters: prefilters

and a HEPA filter. The prefilter section can be fitted with one or

two filters. These prefilters are designed to capture larger

airborne particles and to control odors, depending on the filter

selected. The HEPA section (Position 3), is fitted with a filter

designed to capture 99.97% of smaller particles down to 0.3
