9.3 Disconnecting flexible hoses

Disconnect flexible hoses with the reverse procedure to connecting. Push down

the outer ring of the EMP-14A side joint and pull out the flexible hose.

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.
