Sash Operation
Because of the filtered hood counterbalanced sash mechanism, it will take only a
few pounds of force to move the sash up or down, and you can operate the sash
smoothly with one or two hands positioned anywhere along the handle. The
vertical-rising sash may be raised to a maximum 16-inch operating height for
proper airflow between 60-100 fpm. The airflow requirements should be sized for
the 16-inch operating height. The sash stops allow the Echo sash height to be
increased to 28 inches (26 inches for Airos) only for loading equipment.
Controls
All controls can be found on the Command
Module as described in
Section 6: Filtered
Hood Operating System
. The buttons on the
command module, visible only when available
for use, allow control of the filtered hood.
These are illustrated in Figure 7-4.
Fans
The fans turn on automatically when powering on the filtered hood. To turn them
off, press the
[Fans ON/OFF]
button found on the face of the command module.
To resume fan operation in the filtered hood, press the
[Fans ON/OFF]
again.
Lighting
The internal filtered hood lights are LED and work identically as the fans. They
will automatically turn on with the first power up of the filtered hood. They can be
turned off and on independently of any other action by pressing the
[Lights
ON/OFF]
icon on the command module.
Pressing
[Main ON/OFF]
on the command module will turn off the Smart Halo
Indicator lights of the command module, and will turn off the fans and lights
simultaneously.
Airflow Sensor
Airflow is automatically controlled by the command module of the filtered hood. If
you want to change the rpm of the fans to get a desired face velocity or dwell
time, see the
for this product. If you believe the airflow
sensors are not correctly calibrated, see
Section 4: Calibrating the Airflow
Mute Alarm
This button controls the alarms that sound. To stop an alarm sound press the
[Mute ON/OFF]
button. This will not dismiss the alarm, just the noise. After 10
minutes, if the issue is not resolved, the alarm sound will begin again. For
