Cabinet intake airflow values at 80 fpm [0.406 m/sec]
1) Low Flow Alarm Set Point: The ADJUST screw on the AFM box wants to be set so the yellow light
will come on, then 6 seconds later the red light will turn on activating the audible alarm. (Make sure
the slide switch for the audible alarm is in the ON position). Turning the alarm ADJUST screw
clockwise will move the CFM alarm point up and counter clockwise will move the CFM alarm point
down.
2) Return the exhaust system to it proper flow rate and recheck cabinet intake velocity for HEC
operation.
3) Return the cabinet blower motor speed controller to it original voltage and recheck cabinet intake
velocity for CEC operation.
NOTE: If an exhaust transition or cabinet damper adjustment is performed during a routine cabinet
certification, the AFM alarm should be recalibrated using the steps above.
(For either the Exhaust to Room, CEC or HEC connection).
