the way gas panels a 208/a 209 work
Both cylinders are full and connected. The changeover lever is pointing to the right. The cylinder
valves and process gas inlet valves are now slowly opened. After emptying the cylinder on the right
the regulator automatically switches to emptying the cylinder on the left. The cylinder on the left is
now being emptied and the outlet pressure decreases slightly. To ensure a continuous supply of gas, the
cylinder on the right now has to be exchanged. To do so, the changeover lever is switched to the opposite
left side. The outlet pressure thus increases slightly.
To exchange the cylinder, the cylinder valve and the process gas valve on the right side must be closed.
The remaining pressure is released by opening (and closing) the purge valve. A full gas cylinder is
connected. The continuous gas supply is ensured by the cylinder on the left. Once this one has run out,
a changeover to the gas cylinder on the right happens automatically and the outlet pressure decreases
slightly.
After once again switching over the changeover lever to the right side and exchanging the cylinder on the
left, the whole procedure can start from the beginning again.
The changes in the outlet pressure described when switching the changeover lever and on automatic
changeover to the opposite cylinder is due to the differential pressure settings and necessary for
automatic changeover.
5.2 attaching gas panels
notiCe! The panel is to be mounted securely on the wall. The height it is mounted at measured under
the mounting bar (drill holes of console) is 164 cm.
Warning! To ensure safe handling, wall brackets are to be installed to hold the gas cylinders in place.
Danger! First of all using the nameplate and the labeling check if the gas panel is suitable for the
planned application (type of gas, pressure, material).
Check whether the material of the tubing corresponds to the type of gas to be used i.e. are "matching".
Close the in- and outlet valves on the panel. Then connect the tubing to the outlet of process gas in the
unit or gas panel. As a connection we recommend compression fittings which are already fitted to the
tube outlet if ordered as an option. Assemble by inserting the tube into the opening of the swivel nut of
the compression fitting until the end stop. The swivel nut is then screwed on tightly by hand, "snagged",
at first and then tightened with a fork spanner (1 1/4 turns).
Pressure relief valve and purge outlet if applicable are also connected to a vent gas tubing in the same
way. Please locate the vent gas tubing in a suitable and safe place and make sure it is long enough and
ends over roof (danger to people!).
5.3 Mounting the connecting pigtail/flexible hose to the panel
First of all verify that pigtail/hose "matches" the panel (right gas). A number is stamped in the terminal
nut of the pigtail/hose which corresponds to the number allocated to the type of gas according to
national standards. There is only one type of pigtail/hose connection, suitable for all panels and equally
suitable for the left and the right side. To mount the pigtail/hose on the panel, first of all remove the
plastic protective caps from the inlet thread of the panel and from the end of pigtail/hose. Screw the
compression fitting into the inlet of the panel and tight firmly. Completely insert the tube into the fitting,
then screw the swivel nut onto the connecting thread on the inlet of the panel (by hand first) and then
tighten (1 1/4 turn ), with a fork spanner (SW 17).
5.4 Connecting the pigtail/flexible hose onto the gas cylinder
Danger! The thread on the cylinder valve and the swivel nuts on the pigtail/hose must be in perfect
condition!
Warning! Only ever use new gaskets. Gaskets may not be deformed and must not show traces of dirt
or metal shavings.
Warning! Only ever use original LINDE cylinder connection pigtails/hoses corresponding to the type
of gas being used.
Warning! Ensure gaskets are sitting correctly in the connecting stem of the pigtail/hose. Pay attention
to the right-handed and left handed threads in the terminal nut on the cylinder. Left handed threads
are marked by a milled groove which runs all around the outside of the nut. First of all screw the nut
onto the cylinder valve by hand and then tighten with a fork spanner. While doing so, the handle of the
pigtail/hose must be held from turning.
Warning! Do not use a spanner extension as the thread and the gasket could be damaged. This can
