9.3  Disconnecting Manual Dispense Flexible Hoses 

 

 

 

 

 

 

 

 

Disconnect flexible hoses in the opposite way of connecting. Push down the outer 

ring of the MP-300K side joint and pull out the flexible hose to disconnect. 

CAUTION 

 

 

When disconnecting flexible hoses, make sure that they return to room temperature.   

Note that disconnecting hoses right after dispensing liquid nitrogen may result in 

damaging the O-ring inside the coupler joint.
