To Change the Second 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. Open the pre-filter access door by turning the two
latches counterclockwise (approximately
1
/
2
turn), 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.
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
/
2
turn),
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.
