ARM-EVAC® 250 & 200 SYSTEMS
OPERATION
Arm-Evac 250 Filter Condition Display
The Arm-Evac 250 has a graphical Filter Condition Display which continuously monitors filter
condition. As the system filter(s) collect particulates, LEDs on the Filter Condition Display will
illuminate along the graphical curve of the display.
Initially, a Green LED will illuminate (at bottom of graph). As the air flow rate decreases (as the
filter(s) start to become clogged), LEDs will illuminate high on the graphical curve.
Illumination colors will darken to shades of Yellow and finally to Red as the illumination reaches
the top of the graphical curve.
When the first Red LED illuminates, it is indicating insufficient air flow. Replacement of the filter(s)
at this point is highly recommended. Refer to "Filter Replacement", page 12. If the last Red LED (at
the upper right of display) illuminates, an alarm will sound. Immediately, turn system power off
(Power Switch) and change filters.
CAUTION
Overheating may occur and cause motor damage if the system is operated
with completely clogged filters.
Optional Benchtop Controller for Arm-Evac 250
An optional Benchtop Controller (PIN 8884-2250) is available for the Ann-Evac 250 to enable
convenient access to the three speed flow control switch (refer to item 2, next page), and
surveillance of the filter condition display (refer to item CI, next page).
