8.

 

Open the vent valve on the back of the Fusion. This will create a pressure differential 
sufficient to push the LN2 from the supply tank into the freezer. The vent valve will remain 
open until the Fusion freezer is filled with LN2. 

 
9.

 

As the Fusion freezer and its contents are at room temperature 

for the first fill/charge, fill 

the internal sample storage area with 20-30 liters of LN2 through the neck of the tank using 
the second LN2 supply tank with another transfer hose having a phase separator 

(Not 

supplied)

 
10.

 

Connect A/C electrical power to MVE Fusion power receptacle at the rear.  

 
11.

 

After filling the sample storage area with 20-30 liters of LN2 through the neck, install the lid 

assuring that the lid lock thru hole located in the lid aligns with the lid lock tab located on 

the Dewar neck.
