LIQUEFIER LEVEL AND DISPENSES:
The four lights 4 show the internal level of the
liquefier. If no dispenses are made the unit will enter standby mode.
Dispenses can
be made into the portable Dewar at any time by pressing and holding the ‘Dispense’
button 7.
During dispensing if the “Dispense’ button is released or the Dewar removed the
Dispense will be cancelled to avoid dangerous Liquid Nitrogen spills. The internal
liquefier is capable of holding 1.2Liters of Liquid Nitrogen, when emptied 4 hours
will be necessary before it is completely full again.
Flashing sequential lights indicate the unit is in Standby 11.
