Air Pressure Monitor
The air pressure monitor is mounted on the left
side
of the control panel (comes standard on SGII
ULTRA model and as an option on the SGII
3tandard model). See Fig. 5. The bar graph
12
shows the relative cabinet perfonnance, measured
in terms of the total volume of air being handled
bv the unit.
The top
of the lighted area indicates the relative
airflow. When the airtlow is normal, the LEUs in
the center of the bar graph will glow with a steady
green light.
If just one or two LED's at the bottom of the
graph glow with a red light, the milt is handling a
low volume of air. An alarm will also sound.
This indication mea11s that the unit is not
receiving enough intake air.

vV..4RNING!
If the unit continues to operate in this
condition, it is possible that contamination
may spread outside of the work area. The
product inside the work area may also be
cmttil1n.ina.ted. If you see the- lo1.V airflow
indicator, take these steps:
• Lea<?e the unit running. The. blower will
continue to move air through the cabinet
and filters.
• Close the window completely.
• Call a supervisor and! or a servtce
· ·. techttician.
lf the two LED's at the top blink with a green
light, this indicates a high air flow condition. If
the sash is lowered and the UV light is on, this is a
safe condition.
However, ii you are working in
the cabinet or the sash is at the operating height
(8"), check the intake grilles for blockage. If this
condition persists, call a supervisor or main-
tenance technician. Product protection may be
compromised.
Magnehelic Gauge
Your SteriJCARD"'JI mav be equipped with a
magnehelic gauge in place of the air pressure
monitor (all SCI! Standard models feature the
rnagnehelic gauge). The magnehelic gauge
should be zeroed after the unit has been leveled,
and before it is injtiallv turned on.
