Fill The Process Gas Tubing With Process Gas; Change Empty Gas Cylinder; Taking Manifold Out Of Operation; Tests - GCE druva MPLH0XS0 Instructions For Use Manual

6.5.3. FILL THE PROCESS GAS TUBING WITH PROCESS GAS

Before initial start-up and fi lling the gas tubing with process gas depending on manifold version process gas
purging (see point 6.5.1) or inert gas purging (see point 6.5.2) is necessary Because of safety reasons we
recommend to connect relief gas tubing.
1. Check if purge gas inlets, purge gas outlets, process gas inlets, relief valve and if existent safety valve
and/ or check valves are connected properly
2. All valves are closed, red mark is visible
EN
3. Turn handwheel of the pressure regulator all the way to stop – regulator is closed
4. Slowly open cylinder valve
5. Slowly open inlet process valves.
6. Set outlet pressure with regulator handwheel by turning clockwise
7. Manifold is now in operation
WE RECOMMEND CHECKING THE MANIFOLD AND PRESSURE GAUGES ON DAILY BASIS.

6.5.4. CHANGE EMPTY GAS CYLINDER

NOTE!
•
MAK- Value (see Technical Rules for Hazardous Substances, TRGS 900)
1. Close cylinder valve
2. Close inlet valve on empty cylinder side
3. Open outlet purge valve to depressurize coil/ hose.
4. MPLH0XSP/ MSLH0XSP, MPLHEXSP/ MSLHEXSP: purge with process gas purging (see point 6.5.1)
MSLH0XSE, MSLHEXSE: purge with inert gas purging (see point 6.5.2)
5. Close inlet shut-o valve at empty cylinder side
6. Disassemble coil/ hose from gas cylinder
7. Connect new gas cylinder, use ALWAYS new gasket
BEFORE START UP AGAIN:
8. MPLH0XSP/ MSLH0XSP, MPLHEXSP/ MSLHEXSP:: purge with process gas purging (see point 6.5.1)
MSLH0XSE, MSLHEXSE: purge with inert gas purging (see point 6.5.2)
9. Fill coil/hose with process gas.

6.5.5. TAKING MANIFOLD OUT OF OPERATION

By turning the handwheel anti clockwise close the regulator on manifold.
The closing of regulator guarantees no complete tightness against gas leakage through coils or connected
consumers.
Always close cylinder valve because of safety reasons.
IF THE MANIFOLD WILL BE COMPLETELY DISASSEMBLED, NOTE THE FOLLOWING:
DANGER!
•
Depressurize pressure regulator and tubing through consumer.
•
Inlet and outlet pressure gauge show "0" bar.
•
Appropriate safeguards for personnel are necessary.
•
Note MAK-Values.
•
Unconditionally note that it is not allowed to use the manifold with more than proper pressure.
•
Make sure that nobody is endangered because of start-up of the manifold.

6.6. TESTS

•
After pressurizing the complete function of manifold should be tested
•
Check relief valve
•
Check all valves

7. OPERATION

In reference to chapter 2.1 the operation of the manifold is defi ned.
