Required Qualifications For Initial Start-Up And Cylinder Changing; Initial Start Up; Fill The Process Gas Tubing With Process Gas; Cylinder Change - Linde C300 Gebrauchsanleitung

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 cylinder regulator 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
•
Cylinder regulator is depressurized, handwheel turned completely to left side
•
When using corrosive and/or toxic gases with stainless steel cylinder regulator version TP, TPA, TPB, EP,
EPA or EPB external gas purging needs to take place before initial startup (see point 6.5.2).
WARNING!
•
Make sure the cylinder regulator is not exposed to pressure levels that exceed their respective permis-
sible nominal pressure.

6.5.1. FILL THE PROCESS GAS TUBING WITH PROCESS GAS

Adjust pressure with handwheel turning clockwise. Cylinder Regulator is now in operation.
It is recommended to check the cylinder regulator and the pressures daily.

6.5.2. CYLINDER CHANGE

When using corrosive and/or toxic gases with stainless steel cylinder regulator version TP, TPA, TPB, EP, EPA
or EPB external/ inert gas purging needs to take place before cylinder change.
NOTE!
For external purge gas use dry, clean gas. We recommend using purge gas with a quality according to your
application.
WARNING!
•
During changing gas cylinders with toxic or corrosive gas consider personal safety provisions (breathing
protection, eye protection, protective clothes).
•
Consider MAK-values (see technical rules for hazardous material, TRGS 900), choose correct respirator
fi lter.
DANGER!
•
If the cylinder regulator is used with toxic and/ or corrosive gases, the component have to be purged with
inert purge gas (external gas purging with triple purge block). Therewith dangerous rest gas is removed
through purge gas tubing.
PREPARATION
1. Close cylinder valve
2. Empty pressure regulator, inlet and outlet gauge have to show „0"
3. Turn handwheel of pressure regulator anti clockwise all the way to stop, pressure regulator is closed
4. Close outlet shut off or regulating valve, if existent
5. Process Gas Purging, Discharge Process or External gas Purging for the following version:
TP, TPA, TPB, EP, EPA or EPB, DP
PROCESS GAS PURGING/ DISCHARGE PROCESS
Cylinder regulator with high pressure purge valve (P), or cylinder regulator with downstream purge valve (DP).
Check if purge gas tubing is installed properly. Open and close purge valve to discharge cylinder connection.
