Operation
Before you begin operating the Liquid Nitrogen Trap, read the Liquid Level 1.
Controller manual and familiarize all personnel with the safe handling and
storage of liquefied gases.
Ensure that all three reservoir cover latches have been closed and the 2.
reservoir cover is secure.
Fully insert the level sensor through the reservoir cover. If the sensor is not 3.
fully inserted, liquid nitrogen may overflow and spill out of the vent. Do not
obstruct the vent line, as it could result in a pressure build up.
Open the liquid nitrogen supply valve. 4.
Switch on the Liquid Level Controller and allow time for the liquid nitrogen 5.
reservoir to fill. Ensure that the reservoir cover is properly seated. If it is not,
the proximity sensor will prevent the cryogenic solenoid valve from opening.
When the liquid level in the reservoir reaches 4 inches (10.16 cm), the
controller will close the solenoid valve.
Note: The controller will activate the low-level audible alarm until liquid level rises
above the end of the sensor. It may be muted.
