Specifications

Operation

The vessel can be commissioned immediately after delivery.

Caution !

• Observe safety instructions.

• Use filling line with safety valve and pressure relief.

• Wear gloves and safety glasses.

• Protect the vessel from rolling away, tumbling down

and damage.

Note !

• When cooling down the hot vessel to operating

temperature, increased evaporation losses do occur.

In principle, operate the vessel exclusively by means of the

EK Siphon (2).

When opening the waste gas/overflow valve (1),

make sure that it is not directed towards any

persons or devices; cryogenic gas will cause burns

and brittleness.

Note !

• Due to operation, open valves will get covered by ice

during the pressure build-up, waste gas/overflow and

filling/withdrawal.

• Closed valves will thaw eventually.

• Lasting frost formation indicates leakage.

Assembly of the EK Siphon

1. Clean and remove ice from the sealing surfaces (4),

centering ring (5) and O-ring (6) and replace if damaged.

2. Place the centering ring (5) with O-ring (6) on the flange.

3. Close the filling/withdrawal valve (3) at the EK Siphon.

4. Open the waste gas/overflow valve (1) for avoiding

pressure increase.

5. Insert the EK Siphon (2) vertically into the neck.

6. Place the straining ring (9) and tighten the wing screw (8).

7. Close the waste gas/overflow valve (1).

Liquid nitrogen may escape from the waste

gas/overflow valve when the EK Siphon is

immersed.
