5.4 FILLING STATION (E2K-3)
•Secure the Filling Station to the table.
•Install the flexible high pressure pipe supplied without sharp bends.
•Check the nylon high pressure pipe supplied for any mechanical damage before putting it
under pressure.
•Secure the pipe nuts to the pressure regulator side, then clamp the ferrule to the high
pressure pipe on the gauge block side.
•If the oxygen bottle is not situated close to the Filling Station or if it is in another room or
even outside, then a solid, permanent installation of pressure piping should be installed as
well as a shut off valve and pressure gauge within easy reach of the E2K-3 Filling Station.
•If bottled oxygen is used, a suitable High Pressure oxygen regulator must be supplied by your
Agent, or sourced locally. Ordering this item from the factory ensures that the necessary
modifications have been made to fit the E2K-3 Filling Station.
•The oxygen bottle should be secured according to regulations.
•DO NOT USE ANY OTHER PIPE OTHER THAN THE HIGH PRESSURE PIPE SUPPLIED.
•ALWAYS FILL THE VESSEL WITH OXYGEN TO A MAXIMUM PRESSURE OF 3000KPA
(30 BAR).
•NOTE: With some applications you may need to fill the Vessel to less than 3000KPA
e.g. 1500KPA (15 bar), however this is only applicable when you have a sample
which is highly combustible, for example with wood related samples.
•REMEMBER: You may fill the Vessel LESS than 3000KPA but NEVER more than
3000KPA.
