CONTROL PANEL OVERVIEW (CONTINUED)
VAC Light
The clear VAC pilot light indicates that the vacuum pump is in operation when the auto cycle is
vacuuming down the pass box chamber. The Vac Light does not turn on during manual
vacuuming.
Manual GAS / OFF / VAC Switch
The all black GAS / OFF / VAC switch allows the user to manually initiate a flow of AMG from the
GAS 1 IN port into the pass box by depressing the switch to the left. Pressing the switch to the right
activates the vacuum pump, lowering the atmospheric pressure inside pass box. A combination of
vacuum followed by injections of anaerobic mixed gasses can be used to manually cycle the pass
box.
Fuse
Located on the top back of the unit inside the cord inlet, the fuse protects against over current
conditions. If the fuse blows, the unit will shut down. For your safety and the safety of laboratory
personnel, the cause of a blown fuse should be determined prior to replacing it.
