Connect the relief tubing the same way. It is not allowed to connect relief and purge tubing. They have to go
separately and safe to the outside, also the safety valve tubing.
To connect the gas cylinder to the manifold coils and fl exible hoses are suitable (available accessories)
EN
The stainless steel coils or fl exible hose is always delivered separately. The correct allocation has to be
proved. At the connection nut you can see the type of cylinder connection. There is only one design of coil/
hoses to connect it at the right and left side of manifold.
To mount the coil/ hose please remove plastic caps from the thread. Make sure that the gasket, which is
scope of delivery, is inserted. Connect the nut with the inlet of the manifold hand tight and afterwards screw
with a jaw spanner.
To connect the coil/hose with the gas cylinder, the thread of the cylinder valve and of the nut need to be in
perfect condition. Any time you connect new gas cylinder, use new cylinder connection.
Only coils and hoses from manufacturer suitable for used gases have to be used. Check gasket or correct
position in connection thread of coil/hose. Using a spanner extension is not allowed, it can cause damage of
thread and gasket and leads to leakage.
6.4. REQUIRED QUALIFICATIONS FOR INITIAL START-UP AND CYLINDER
CHANGING
•
The test protocols from the piping according to tightness and if necessary moisture and particles are
available
•
Process gas tubes, vent piping and purge gas tubing, safety valve and check valve tubing if existent is
connected
•
In process gas tubing is only standard gas ( see 1.2)
•
The start-up is only realized by qualifi ed personal
•
Wear safety clothes according to regulations
•
Use spark-free tools and provide before installation
•
Before fi rst start-up check type label, if the manifold is suitable for the provided purpose (gas, pressure,
material, etc.)
6.5. INITIAL START UP
•
All requirements are fulfi lled as on point 6.4
•
Manifold is depressurized, handwheel turned completely to left side
•
All valves on manifold are closed
WARNING!
•
Make sure the manifold components are not exposed to pressure levels that exceed their respective
permissible nominal pressure.
•
Make sure that nobody could be hurt because of the initial start-up of manifolds.
6.5.1. PROCESS GAS PURGING (S300/S200/S60)
Manifolds with process gas purging were used to get air from the atmosphere out of the components, before
you change cylinder or you want to depressurize coil or hose before cylinder change.
1. Valve for process gas purging is closed, toggle is transverse to the direction of fl ow (2-port valve)
2. Pressure regulator is depressurized (closed)
3. Close inlet shut-off valve, red marking is visible (4-port valve)
4. Now the inlet shut-off valve is just closed in direction pressure regulator. The way through purge valve
is open.
5. Slowly open cylinder valve
6. Process gas is streaming into coil/ hose
7. Close cylinder valve
8. Shortly open purge outlet valve and let the gas from the coil/hose go
9. Immediately close purge outlet valve after that
REPEAT STEPS 4. 9. FOR MINIMUM 10 TIMES
