8.3.3. NECESSARY MAINTENANCE

•
Check accuracy of pressure gauges
•
Manifold, pressure regulator, valve and gauges: check condition, function and labeling
•
Check labelling
•
Check for corrosion
•
Check function
•
Pressure test with 1-times working pressure for 12 hours
•
EN
Worn and defective components must be changed immediately from authorized qualifi ed company
•
Valve is designed according to ISO 10297, including type test with cycle test from up to 2000 cycles.
Change inner parts after 2000 cycles, change must be done from authorized qualifi ed company
•
If there are any leakages or too much corrosion at the manifold/ pressure regulator or valve, component
must be replaced with all connections by an authorized company
•
After the changing of components or tubes, pressure and leakage test must be done again and be proto-
colled

8.4. MEASURES FOLLOWING MAINTENANCE

THE FOLLOWING STEPS MUST BE PERFORMED WHEN THE MAINTENANCE WORKS HAVE BEEN
COMPLETED AND BEFORE SWITCHING ON THE SYSTEM.
1. Make sure that all tools, materials and other equipment have been removed from work area.
2. Clean the work area and remove any spilled substances, e.g. liquids, processing material or similar.
3. Make sure that safety relevant components are working perfect.

9. TROUBLESHOOTING

The following section describes possible causes of malfunction and how to eliminate them. If malfunctions
occur with increasing regularity, shorten the maintenance intervals to refl ect the actual load. If malfunctions
occur that cannot be eliminated with the following help, please contact the manufacturer (see section 1.8 for
contact details).

9.1. SAFETY NOTES FOR TROUBLESHOOTING

In any case of malfunction, the shut-o valves oft he connected gas cylinder, gas container or bundle must be
closed. Never operate devices with malfunctions under pressure.
WHAT TO DO IN CASE OF MALFUNCTION:
1. Interrupt and ensure gas supply.
2. Depressurize pressure regulators and close valves.
3. Only trained technical sta may eliminate malfunctions.
4. Restore component to its original state.
