The size and concentration of airborne contaminants, temperature and humidity conditions, and duration of use
determine how often filters need replacement. If the Pre-filter Filter Change Indicator on the control panel
illuminates, this indicates one or more of the following: (1) pre-filter(s) are loaded, (2) the inlet is obstructed,
and/or (3) the flex duct, if attached to inlet, is too long or has too many bends. If the HEPA Filter Change Indicator
on the control panel illuminates, this indicates one or more of the following: (1) HEPA filter is loaded, (2) the inlet
or outlet is obstructed, and/or the flex duct, if attached, is too long or has too many bends.
If using an activated carbon filter, the method of determining when to replace this particular 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 Indicator
The Filter Change Indicator lights illuminating indicate one or more of the following:
1. Loaded filter(s). Refer to FILTER CHANGE PROCEDURE.
2. Restrictions on air intake. Refer to TROUBLESHOOTING GUIDE.
Filter Change Procedure
The filter change indicator lights located on the control panel will indicate when one or more of the filters need to
be changed. This is based on a factory setting and the filters can be changed earlier, if desired, to maintain a
minimum air flow requirement.
Note:
Since the Primary Filter Change Indicator Light is based on the pressure drop across all of the pre-filters,
it cannot indicate specifically which filter needs to be changed. Therefore, when the Filter Change Indicator Light
illuminates, the first stage filter should be changed first to see if the light turns off. If the light remains, then the
second stage filter should be changed followed by the optional third stage filter.
Changing the First Stage Filter:
1. With the unit operating, turn the latch on the pre-filter access door counterclockwise (approximately ½
turn), and open the door.
2. Remove the first stage filter and replace it with a new one. Be sure to slide the filter all the way into the
unit’s cabinet.
3. Close the door and lock it in position by turning the latch clockwise. Make sure the door is flush against
the PRED1200 cabinet before closing latch.
4. If the pre-filter change indicator remains “ON” after changing the first stage filter, the second stage filter
should be replaced.
Changing the Second and/or Third Stage Filter:
1. Open the pre-filter access door.
2. Remove the pleated filter and replace it with a new one.
Note:
If a 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.
