Safety Information
Keep Children Away: Do not allow children to play with or
around the unit. It could result in injury. Be sure the unit is inac-
cessible to children when not attended.
Keep Unit Grounded: Always operate the unit with a grounding
plug and a grounded electrical outlet. A grounding plug is an
essential safety feature that helps reduce the risk of shock or
fire.
Protect Power Cord from Damage: Never operate a unit with a
damaged power cord, as this may lead to electrical or fire haz-
ards. If the power supply cord is damaged, it must be replaced
by a cord of the same type and amperage rating.
Extension Cords: Extension cords must be grounded and able
to deliver the appropriate voltage to the unit.
Handle With Care: Do not drop or throw the unit. Rough treat-
ment can damage the components or wiring and create a haz-
ardous condition.
Run on Stable Surface: Always operate the unit on a stable,
level surface, like the floor or a strong counter, so it cannot fall
and cause injury.
Secure During Transport: When transporting in a vehicle, se-
cure the unit to prevent sliding and possible injury to vehicle oc-
cupants.
Keep Out of Water: Never operate the unit in pooled or standing
water, as this may create a risk of injury from electrical shock. Do
not store or operate outdoors. If electrical wiring or components
become wet, dry thoroughly before using the unit.
Keep Air Intakes Clear: Do not clog or block air intakes, as may
occur if operated to close to draperies or similar materials. This
may cause the unit to overheat and result in a fire or electrical
hazard.
Use Clean Filters: Clogged or dirty filters may limit the airflow
through the DefendAir. Change the pre-filters after every job.
Change the primary filter after every remediation job. The filter
change indicator lights will alert you when the filters need to be
changed during the course of operation.
Dispose of used filters in accordance with applicable regula-
tions. Always wear an appropriate NIOSH-approved respirator
and, if needed, other appropriate personal protective equipment
when changing or disposing of used filters. Always use new
filters and pre-filters to prevent cross-contamination between
jobs.
Keep Electrical Components Dry: Never allow water inside the
DefendAir's electrical components. If these areas become wet
for any reason, dry thoroughly before using again.

GUIDE TO AIR SCRUBBING
The DefendAir EX helps filter airborne particles from the air that
may be released during typical remediation and/or restoration
procedures.
pollens, pet dander and miscellaneous debris.
High Efficiency Primary Filters
The filter media used in the DefendAir EX's primary filter meets
HEPA efficiency standards when tested under the IES-RP-
CC001.3 standard. Once installed, the primary filter operates at
efficiencies slightly below HEPA levels but is still capable of cap-
turing 99.5% of particles as small as 0.3 microns from air pass-
ing through the filter. This filter therefore provides very high par-
ticle filtration efficiency. It excels at capturing fine particles with
extremely low airflow resistance. This results in greater through-
put of air and faster cleanup.
By itself, the primary filter will not remove volatile organic
compounds (VOCs) and other vapors and odors. Pre-filters are
available for the DefendAir that will filter nuisance levels (i.e.,
levels below OSHA Permissible Exposure Limits) of VOCs and
other vapors.
Use for Water Damage
In a standard Category 1 water damage situation, place the De-
fendAir EX in the middle of the affected area. A typical restora-
tion process dislodges millions of microscopic particles from wet
carpet, pad and other materials and circulates them through the
air. The DefendAir filters the air in the affected area to reduce
particle levels during the restoration process.
Use for Remediation
In most cases, the remediation process requires containment of
the affected area. Containment prevents the spread of mold
spores and other bioaerosols during the remediation process.
See "Containment During Remediation" for more information.
Use the DefendAir as a negative air machine for remediation.
A negative air machine vacuums air from a containment area to
create a negative air pressure on the inside. See "Negative Air
Pressure" below for more details.
Run the DefendAir without interruption for the duration of
every remediation job. The DefendAir filters 99.5% of particles
0.3 microns and larger, such as mold spores and fungi from the
air passing through the filter.
