6.1.5 Run Mode
Any time the blower run key is pressed with the hinged window at its correct operational height, the RUN MODE
screen will be initiated. The Run Mode will start with the PresurFlow™ entering and approximate 3 minute warm
up period. The PresurFlow™ LED indicators will blink and indicate the following sequence:
• 1 st minute – Left and right Red LED’s will blink
• 2 nd minute – Left and right Green LED’s will blink
•
3 rd minute – Center 3 Green LED’s will blink
Once the warm up period is complete, only one LED will indicate cabinet airflow status.
During the warm up period the cleaning process may begin. If the hinged window is raised, an audible and visual
alarm will occur, but may be silenced by pressing the alarm silence key.
6.1.6 Temporary Low Flow Mode
The NU-813 may be configured to allow the airflow to be temporarily lowered, but still provide some level of
protection for sensitive procedures. Typically, airflow in this mode is set to provide an average of 50 fpm versus
the standard 80 fpm. If temporary low flow mode is configured (see section 8.2.2), the blower must be on (green
LED above blower key will blink) and the window in its normal position. To activate, press the blower key for 5
seconds, once activated, blower LED indicator will blink fast and the PresurFlow™ will indicate 3 green LED
indicators will blink. The low flow mode will stay active for the timed duration (normally 15 minutes as
programmed, see 6.1.8.2) or can be terminated by pressing the blower key, for 5 seconds.
6.1.7 Standby/Run Mode Alarms
If present, standby/run mode alarms will be both visual and audible, the red alarm LED oval will turn on. Audible
alarms will produce an alarm tone for 30 seconds, then ring back for 2 seconds of every 5 seconds. Pressing the
alarm silence key will silence the audible alarm for 15 minutes initially then will start the ring back function again .
