GENERAL INFORMATION
The PREDATOR® Portable Air Scrubber is a multi-use air filtration device, equipped with pre-filters and a HEPA
filter that are capable of filtering many airborne contaminants. An alternate carbon pre-filter for capturing low
concentrations of odors, vapors, gases, and volatile organic compounds, collectively known as OVG, is also
available.
Types of contaminants captured by particulate pre-filters, HEPA filter, or carbon filters:
• Dirt
• Lung-damaging particles
• Low concentrations of OVG
• Dust
• Metal fumes
• Low concentrations of Volatile
Organic Compounds (VOC)
• Drywall dust
• Smoke
• Saw dust
• Mold and fungal spores
• Unpleasant nuisance odors
Note: To capture low concentrations of OVG, a Vapor-Lock® carbon filter must be used.
The PREDATOR® Portable Air Scrubber is capable of providing particulate and odor, vapor, gas filtration with
final stage filtration through a High Efficiency Particulate Air (HEPA) filter. This unit incorporates a series of
particulate filters that successively remove larger size to smaller size particles from the air. In addition to
providing HEPA filtration, the PREDATOR® Portable Air Scrubber is primarily used in a negative pressure or
recirculation mode. A negative pressure condition is created in order to confine contaminated airborne
particles. This condition exists when the static pressure inside the room containing the unit is lower relative to
the pressure of the environment outside the room. The static pressure differential is created and maintained by
continuously exhausting air out of a given room at a faster rate than air enters the room from all other sources.
In the recirculation mode, all of the filtered air is exhausted back into the room containing the unit.

3
STANDARD AIR CLEANING STAGES (FILTERS SUPPLIED WITH THE UNIT)
The PRED750 comes equipped with two progressively efficient pre-filters mounted in the pre-filter
compartment, and a final stage HEPA filter, located inside the cabinet:
•The first-stage 1" deep, coarse particulate pre-filter (F621) is designed to capture particles 100 microns
or larger.
•The second-stage 2" deep, particulate pleated pre-filter (H502) is designed to capture particles 10
microns or larger.
•Each HEPA filter (H161606-99) is tested & certified to capture at least 99.97% (9,997 out of 10,000) 0.3-
micron particles.
Note: The particulate filters included with this unit do not remove odors, vapors or gases, including volatile
organic compounds.
ALTERNATE SECOND STAGE FILTER: VAPOR-LOCK® CARBON FILTER
(MUST BE PURCHASED SEPARATELY)
Vapor-Lock® pleated, high-capacity, carbon filters (part # VL1002) are available for capturing OVG. This 2"-deep
filter can be used in place of the second-stage H502 pleated pre-filter to reduce airborne OVG by chemically
bonding the OVG molecules to the surface area of the carbon granules, via a process known as adsorption. The
VL1002 filter also provides a similar level of particulate filtration efficiency to the H502 pre-filter.
Effective carbon adsorption is dependent upon the amount of carbon & exposed carbon granule surfaces, and
the dwell (contact) time the OVG molecules have with the carbon granules. Operating the unit at lower speed
settings to increase dwell time can therefore improve OVG adsorption, though it is highly unlikely that all of the
OVG will be removed in one pass of air through the unit. Operating the unit in the recirculation mode can
increase effectiveness, by exposing OVG particles to multiple– passes through the Vapor-Lock filter.
It is almost impossible to provide accurate estimates to two commonly asked questions: “how much time will it
take to capture all of the OVG?”, and “how do I know when a carbon filter should be replaced?” Unfortunately,
unknown factors, such as concentration levels, fresh-air intake volume, temperature, and humidity prevent
establishment of any more accurate ‘rule of thumb’ than one’s sense of smell. Since off-gassing of adsorbed
OVG can occur when the adsorption capacity of the filter is reached, replace the carbon filter as soon as odor
breakthrough is sensed. More detailed information on carbon adsorption can be found in an article titled:
“Activated Carbon: How Is It Used? How Does It Work?” which can be found on the Abatement Technologies
website, www.abatement.com.
HOW TO DETERMINE THE REQUIRED NUMBER OF AIR FILTRATION DEVICES (AFD)
1. Calculate the total air volume (V) in cubic meters (ft³) within the enclosed containment area by
multiplying the length (L) x the width (W) x the height (H), all in meters (V = L x W x H).
2. Determine the minimum number of air changes per hour (ACH) specification. When no ACH number is
specified, most users target at least 6 ACH for construction areas. Building in a safety factor to
compensate for filter loading, duct losses, reduced voltage and other factors that can reduce actual
installed airflow is a good practice. For example, if 6 ACH is the objective, you might design for 8 ACH.
3. Select an Abatement Technologies air filtration device (AFD) model and determine the peak airflow
rating for that model in cubic feet per minute (CFM).
4. Determine the total number of AFD required using the following formula: Quantity = (V x Design ACH) /
(AFD Rating x 60)
5. Always round up to the next whole number. For example, if the total number of AFD required is 2.13, 3
units are recommended, not 2.

4
Example: How many air filtration devices (each with 600 CFM rated airflow) would be required to
provide 8 ACH (including a safety factor) in a 40ft L x 24ft W x 10ft H containment area?
a. V = 40ft x 24ft x 10ft = 9600ft³
b. Design ACH = 8
c. Quantity of AFD required = (9600ft³ x 8 ACH) / (600CFM x 60) = 76,800/36,000 = 2.13
units
d. 2.13 units → 3 units required.
ELECTRICAL REQUIREMENTS
1. The PREDATOR® Portable Air Scrubber requires a minimum of 110 volts AC, 60 Hz to operate properly;
however, maximum airflow performance requires 120 volts AC, 60 Hz.
2. Due to momentary start-up current surge, the unit requires a 15 amp circuit that is free of other loads.
3. Extension cords used for this unit must be UL-listed, heavy duty No. 14/3 AWG SJTW industrial grade 3-
wire type. Use of larger numerical gauge (lower capacity wire) power cord(s) may result in electrical
shock, fire hazards and/or damage to unit. The cord(s) must be in good condition and in continuous
lengths (no splicing) and should not exceed a total of 50 feet in length. Make certain that any extension
cords used do not reduce power to the unit to less than 110 volts. Use of a voltmeter to confirm
adequate voltage is recommended.
4. Check to ensure that any circuit to which the unit is connected is protected by a 15 ampere circuit
breaker. The unit itself is equipped with a 12 amp circuit breaker.
5. This unit should be connected to a three-prong, properly grounded electrical outlet equipped with a
Ground Fault Circuit Interrupt (GFCI) device. A GFCI is an electrical safety device that will trip the circuit
and stop the flow of electricity if leakage of current is detected.
Important Note: The GFCI on this unit's control panel only detects leakage of current from the unit or
an electrical device plugged into the GFCI. This unit should be plugged into a GFCI receptacle at the
power source to protect the power cord and the unit. This GFCI will trip the circuit if it detects
leakage of current from the power cord or unit.
6. To avoid personal injury, fire hazards and/or damage to the unit's electrical system and power cord, do
not connect or disconnect the power cord to an electrical outlet unless the speed control switch is
“OFF”.

OPERATING THE UNIT
IDENTIFYING KEY COMPONENTS OF THE CONTROL PANEL
1. Power Cord - Hardwired, 14/3
AWG SJTW power cord for
connection to electrical outlet.
2. Power Indicator - Green light
that indicates speed control
switch is “ON” and system is
connected to power source.
3. Speed Control Switch - Serves
as the power switch and
provides a variable adjustment
to the speed of the motorized
impeller.
4. Filter Change Indicator – Red
light that indicates excessive
restriction on intake or loading
of the filter(s) and that filter
change procedures should be
followed. Check the Filter
Change Indicator when the unit
is operating at “HIGH” speed.
5. Circuit Breaker - 12 amp circuit breaker that provides protection for the unit’s electrical components.
6. GFCI Receptacle - Electrical safety device that will trip and stop the flow of electricity if leakage of current is
detected from the unit or an electrical device plugged into the GFCI receptacle. The PRED750 can supply a
total of 8 amps of electrical power for additional equipment that is connected to the GFCI receptacle. Do
not exceed this 8 amp limit. Note: If the equipment connected to the GFCI receptacle draws more than a
total of 8 amps, the circuit breaker on the control panel and/or the building breaker will trip. This condition
can be remedied only by reducing the total amperage draw.

7
BEFORE OPERATING THE UNIT, NOTE THE FOLLOWING:
Inspect and tighten any HEPA filter retaining nuts that may have loosened during transportation. Inspect the
filters for any material or structural damage prior to use and replace any damaged filters before operating the
unit. When removing any filters prior to operation, always put them back in place with airflow indicator on filter
housing oriented in the proper direction (if applicable).
Be sure to remove the foam plug from the inlet before use. Keep this foam plug so that the inlet can be plugged
again after use to contain any debris that has been captured in the machine.
As with any air filtration system, external airflow losses not attributable to the air filtration unit will reduce the
airflow of the system. The following recommendations can minimize airflow losses created by external static
resistance.
1. Always use the minimum length of ducting possible with the fewest possible number of turns and
bends.
2. Rigid metal ducting creates less turbulence and consequently less airflow loss than flexible ducting.
Regardless of the type of ducting used, rigid, “sweep-type’, radiused connections should be used for all
turns and bends.
3. If flexible ducting is used, it must be kept as taut as possible to avoid flattening.
LOCATION OF THE UNITS AND MODES OF OPERATION
1. Negative Pressure - used to help ensure that airborne contaminants do not escape from a contained
area, by maintaining negative (lower) air pressure within that area compared to adjacent areas. This is
generally accomplished by placing the unit inside the containment area and exhausting filtered air from
the unit out of the area. The filtered air must be exhausted outside of the containment area, either
directly to the outdoors, or into another part of the building. To maintain negative pressure, the air
exhaust must exceed the air supply by the greater of: 10% or 170 m3/h (100 CFM). To achieve this
differential, the air supply volume to the area may have to be reduced. Negative pressure levels should
be continuously monitored.
2. Recirculation - used to reduce concentrations of airborne contaminants in a room or area by
continuously cleaning the air and exhausting it back into the same room or area.
3. Positive Pressure - used to help prevent airborne contaminants from entering a containment area, by
keeping that area under positive pressure compared to adjacent spaces, so any air leakage will be an
outflow of clean air, and not inflow of contaminated air. This pressure differential can be established by:
a. placing the unit inside the containment area, and using it to pull air into the area by attaching
flex duct between the inlet collar and a location outside of the containment area.
b. placing the unit outside of containment area, and using it to push HEPA-filtered air into the area
through flex duct attached between the outlet collar and a location inside the area.
To ensure that the proper pressure differential is maintained, the volume of HEPA-filtered air supplied
to the area must be the greater of: 10% or 170 m3/h (100 CFM) higher than the volume of air exhausted
from it by the HVAC system. Positive pressure levels should be monitored continuously.
Important Note: Do not operate the unit unless the pre-filter(s) and HEPA filter are installed, and the filter
access door and panel are in place and closed.
DAISY CHAINING
“Daisy Chaining” refers to the operation of multiple units on one circuit, with only one of the units plugged into
a 120V/15A electrical power supply receptacle. Each subsequent unit is plugged into one of the GFCI receptacles

8
on the prior unit, up to the maximum number allowed based on the amperage draw per unit. The National
Electrical Code (United States) limits the total amperage draw of devices operating on one circuit to 80% of full
load, which means that the total amperage draw on a 120V/ 15A circuit, including the unit plugged into the
building electrical power supply receptacle, must not exceed 12 amps. A total of five PRED750 units can be
“Daisy Chained” on a 15 amp circuit, including the unit plugged into the building electrical power supply
receptacle.
TO START UNIT
1. Check to make sure that the Speed Control Switch is in the “OFF” position. Plug power cord into a 120
volt AC, 60Hz, 15 amp supply circuit.
2. Turn Speed Control switch clockwise past the click at the “HIGH” setting to turn power “ON”.
3. Set Speed Control switch to desired setting.
Note: Refer to the chart in this instruction manual entitled "PRED750 SPECIFICATIONS" that lists the
airflow range for the PRED750.
Note: In the event of a power failure while the unit is running, or loss of power due to any other cause, this
unit’s motorized impeller will re-start when power is restored, after a brief delay.
FILTER CHANGE INDICATOR
Light “ON” indicates one or more of the following:
1. Loaded filter(s). Refer to filter change procedures.
2. Restrictions on air intake. Refer to Troubleshooting Guide.
STACKING THE UNITS
The PRED750 Portable Air Scrubber units can be stacked up to 3 units high total. The bottom of the unit is
designed to nest into the top of another PRED750 unit. Since the filters are accessed through a hinged door, the
filters can be changed while in the stacked configuration. It is not recommended to stack more than 3 units
high due to safety as well as the compounding weight of the units.
STORAGE AND TRANSPORT OF THE UNIT
TRANSPORTING THE UNIT
The PREDATOR® Portable Air Scrubber should be transported in its normal position (resting on its rubber feet). If
extremely poor road conditions exist, or excessive shock and vibration are expected, take precautionary
measures by padding the unit to provide impact absorption during transport.
The units can be stacked up to 3 units high total for transporting purposes. However, the stacked units must be
secured in such a way as to prevent the units from falling.
Caution: Always use caution when moving the PREDATOR® Portable Air Scrubber inside a building or home. The
unit weighs 35 pounds. Older structures with weakened floors or staircases may require special considerations
for safe transport.
FOAM INLET PLUG
The PREDATOR® Portable Air Scrubber comes with a foam plug that fits into the inlet of the unit. Be sure to
remove the foam inlet plug before use and insert it back into the inlet after use. The foam plug keeps any
collected contaminants that are caught in the filters or inside the cabinet from escaping the unit when the unit is
not in use.

9
CORD WRAP
The PRED750 has a built-in cord wrap for storing the power cord when not in use. It is important that the cord
is wrapped to help protect the cord from damage during transport and storage. Wrap the cord as shown in the
picture below and secure the plug head to the cord using the integrated clip.
USER SERVICING INSTRUCTIONS
Abatement Technologies' portable air scrubbers are designed to be low maintenance devices and basic
maintenance should be performed as follows:
•Filters should be changed as needed based on the filter change indicator light. Follow the FILTER
CHANGE PROCEDURE as described in this manual. Filters can be changed earlier, if desired, to maintain
a minimum required flow rate.
•The unit should be cleaned with a damp cloth or a water-based cleaner/sanitizer as needed. Do not use
harsh chemicals, solvents or detergents to clean the unit. Warning: Keep electrical components dry as
their exposure to liquids poses a safety hazard and can damage components.
•Test the GFCI located on the unit's control panel on a monthly basis to ensure proper operation.
1. Plug the unit in and verify that the GFCI on the control panel is receiving power by ensuring the
green light in the corner of the GFCI is illuminated.
2. Depress the "TEST" button until you hear a click; the green light on the GFCI should turn off.
3. Depress the "RESET" button on the GFCI until you hear a click; the green light on the GFCI
should turn on.

10
FILTER REPLACEMENT
Note: Personnel responsible for changing filters, servicing units or relocating units within the facility are urged
to wear the proper personal protective equipment (PPE) and follow safe work practices in accordance with
federal, state, provincial, local and employer regulations. Abatement Technologies cannot recommend the
type of PPE required as that will need to be determined by safety/risk assessment personnel based on various
risk factors, including the type of particulates being captured by the air filtration device and the surrounding
environment where the units are being used, transported, or serviced.
Note: Filters being replaced must be disposed of in accordance with federal, state, provincial, local and facility
regulations.
System airflow reduction is generally the result of filter loading, blockage of the unit’s inlet or use of excessive
lengths of flex duct that is connected to the inlet.
The size and concentration of airborne contaminants, temperature and humidity conditions, and duration of use
determine how often filters need replacement. If the Filter Change Indicator on the control panel illuminates,
this indicates one or more of the following: (1) filter(s) are loaded, (2) the inlet is obstructed, and (3) the flex
duct, if attached to inlet, is too long or has too many bends.
The method of determining when to replace an activated carbon filter is somewhat subjective. As the odor,
vapor, and/or gas filtration capacity decreases, the user will begin to sense a slight odor or taste of the
contaminant, indicating that the filter should be replaced.
Note: The filters are not reusable, therefore, do not attempt to clean and reuse them.
Caution: Abatement Technologies PREDATOR® Portable Air Scrubber units are designed to meet or exceed
standards for high efficiency air filtration equipment. Use only Abatement Technologies parts, including
replacement filters. Use of non-Abatement Technologies parts and filters voids the product warranty and all
performance claims.
Warning: To reduce the risk of fire, electrical shock or personal injury, always turn the unit “OFF” and
disconnect the power cord from supply receptacle before replacing the HEPA filter and before cleaning or
servicing the unit.
FILTER CHANGE PROCEDURE
To Change the First Stage Filter:
1. With the unit operating, turn the two latches on the pre-filter access door counterclockwise (approx ½
turn), swing the latches outward, and open the door. Remove the first-stage filter located inside the
door itself and replace it with a new one.
2. Close the door and lock it in position by swinging the latches inward and turning the latch clockwise.
Make sure the door is flush against the unit's cabinet before closing the latch.
3. If the Filter Change Indicator light remains “ON” after changing the first-stage filter, the second- stage
filter should be replaced.
To Change the Second Stage Filter:
1. Open the pre-filter access door by turning the two latches counterclockwise (approximately 1/2turn),
swing the latches outward, and open the door.
2. Remove the second-stage pleated filter and replace it with a new one. The pleats on the air filter should
be oriented so that they are vertical and the air flow directional arrow on the filter should point toward
the control panel.

11
Note: If an alternate VAPOR-LOCK® filter is being used, be sure to remove it from its poly bag before
installing it in the unit. VAPOR-LOCK® filters are packaged in poly bags to preserve the integrity of the
carbon granules.
3. Close the door and lock it in position by swinging the latches inward and turning the latch clockwise.
Make sure the door is flush against the unit's cabinet before closing the latch.
4. If the Filter Change Indicator light remains “ON” after changing the second-stage filter, the HEPA filter
should be replaced.
To Change the HEPA Filter:
1. Turn the unit “OFF” and disconnect the unit’s power cord from the electrical outlet.
2. Open the pre-filter access door by turning the two latches counterclockwise (approximately 1/2turn),
swing the latches outward, and open the door.
3. Remove the second-stage pleated filter. The HEPA filter is located behind the pleated pre-filter.
4. The HEPA filter is held into place by two metal brackets. Remove the two screws from each bracket and
then remove the HEPA filter from the machine.
5. Insert the new HEPA filter with the pleats oriented vertically and the air flow directional arrow on the
filter pointing towards the control panel (the gasketed side of the HEPA filter will be against the internal
wall).
Note: The HEPA filter is delicate and should be handled with care. When removing or reattaching the
HEPA filter retaining brackets, do not touch the filter media; otherwise, damage to the filter and leakage
of contaminated air could result.
6. Replace the two metal brackets and secure the brackets with the screws.
Important: Do not use a power screw driver or drill to tighten the screws down as this may strip the
screw head; tighten with a manual screw driver only.
7. Insert the second-stage pleated filter into the machine. The pleats on the air filter should be oriented so
that they are vertical and the air flow directional arrow on the filter should point toward the control
panel.
8. Close the door and lock it in position by swinging the latches inward and turning the latch clockwise.
Make sure the door is flush against the unit's cabinet before closing the latch.
Note: The HEPA filter is not designed to be cleaned and using methods such as compressed air in an attempt to
clean the filter can cause damage to the filter and comprise the HEPA filter efficiency rating.
Warning: Use only Abatement Technologies pre-filters, HEPA filters, and replacement parts. Substitute parts
void the warranty, jeopardize worker and environmental safety, and adversely affect engineered
performance levels.

Warning: To reduce the risk of fire, electrical shock or personal injury, always turn the unit “OFF” and
disconnect power cord from supply receptacle before removing the control panel, replacing the HEPA filter
and before cleaning or servicing the unit. This unit is equipped with an automatic restart motorized impeller
that will restart without warning after a temporary power interruption or recovery from a thermal overload
(over-heating) condition. Keep clear of the motorized impeller at all times to reduce the risk of injury.
Occasionally a defective component will cause the unit to operate improperly or not at all. Any electrical
component can fail. Refer to the Wiring Diagrams and Wiring Schematics to diagnose the failure of any
component. Diagnostics should only be performed by a technician qualified to service electrical equipment.
