Filling
1. Mount the EK Siphon.
2. Connect the filling line from the tank to the
filling/withdrawal valve.
3. Open the waste gas/overflow valve for causing pressure
relief.
4. Open the filling/withdrawal valve at the EK Siphon.
5. Open the tank valve for filling the vessel.
6. Close the tank valve when liquid nitrogen escapes from the
waste gas/overflow valve .
Caution!
Risk of skin burns
After completion of filling:
Waste Gas/Overflow Valve (3) to leave open.
1. Close the filling/withdrawal valve (1) at the EK Siphon.
2. Relief pressure from the filling line (2).
3. Loosen the filling line (2).
4. Dismantle the EK Siphon.
5. Move the tank (with the transport stopper loosely inserted)
to its destination.
6. Remove the transport stopper.
7. Mount the EK Siphon.
Risk of skin burns by escaping nitrogen
Filling without EK-Siphon in open condition
Alternatively to the procedure described above the vessel
may be filled by a hose with phase separator in open
condition. The filling has to be stopped prior the liquid level
reaches the neck tube.
1. depressurise and unmount the EK-siphon
2. let liquid inflow trough the neck tube in open condition
3. stop filling procedure prior liquid level reach the neck tube
(liquid level gauge 5% under max-indicator)
4. mount the EK siphon
(ball valves 1 + 2 closed)
5. open overflow valve 3: overfilled liquid will escape
