Step 2
With the filtered hood powered,
move the sash to your desired
working height. It is recommended to
be 2 to 3 inches above the working
height to avoid nuisance alarms due
to room pressure changes. Once in
place, DO NOT move the sash until
the calibration is completely over.
Step 3
Turn the fans off by pressing [Fan
ON/OFF] on the front of the
command module.
Step 4
For 10 seconds, hold the [Power
Button] down. This will cause the
maintenance and containment icons to appear in red on the front of the command
module. The appearance of the command module will match Figure 4-10 with the fan
icon blinking.
Step 5
With the command module as shown in Figure 6-1 (with the Command Module
Signature Light blinking), press the Fan ON/OFF button to start calibrating. This will
begin the configuration process.
Note: After step 5 do not attempt to operate the filtered hood or move the sash from the
working position. Any changes made during the calibration process will cause
inaccuracies in the calibration. The following steps require no action.
Step 6
With the fan(s) off the filtered hood will stabilize for about 30 seconds and an audible
chime will be heard from the command module to signal the filtered hood is completely
stable.
Step 7
In a stable filtered hood with the fan off, the anemometer will take readings for about a
minute and calculate the zero (no airflow) value. Once complete, another chime will
play.
