
With the facility HVAC running you will see the Current Reading , compare that to your calibrated setting.

Taking in consideration any variance between the current reading and calibrated setting, set your alarm
threshold. Most facilities actual airflow will vary based on door opening time and frequency to a lab so it is
advisable to set the threshold at least 10% lower than the nominal air flow value.
 If the actual air flow drops below the set Alarm Threshold it will change the ICON on the Status screen and log an
event in the system memory.
6.2.8 Recirculation System Option
Recirculation option is intended for facilities that do not have available HVAC exhaust flow available for temporary use
or in limited use environments. The backdraft air is pulled through the hood by variable speed blowers and cycled
through filters in an effort to remove particulates and fumes before exhausting back into the room at the top of the unit.
Variable recirculating blowers are loud and operate between 65-82 decibels (dBa).
 Turn on the Recirculation Fans by touching the action button.
 On/Off is controlled via a button on the Recirculation Fans screen.
 Fan Blower speed is adjustable in 10% increments. Most users will see an appropriate flow set around 70%
speed with a properly maintained filter.

The Airflow Alert can help you determine when your filters are getting plugged with airborne particulates.
o Set the Airflow Alert by using the lab manager access (passcode 1 2 3 4) into Setup and then to the
Configure tab. See section 6.2.7 for more information.
