Concoa 537 Series Kurulum ve Çalıştırma Talimat Kılavuzu
Pressurizing the System for the First Time (Non-Manifold Use):
Before system startup, it is recommended that all systems be pressure tested, leak tested, and
purged with an inert gas such as nitrogen. To accomplish this with connections other than CGA
580, it will be necessary to use an adapter. The recommended use of an adapter is for temporary
use only for system start up and checks. Adapters should never be used on a permanent basis.
1. Wear safety glasses and gloves.
2. Be sure that both ends of all pigtails are secured before pressurizing. Turn the line regulator
knob counterclockwise until the knob stops turning.
3. When first pressurizing, do not stand in front of or contact the switchover system. Slowly
open the cylinder valve. Observe the high pressure gauge for a rise in pressure up to full
cylinder pressure.
4. Keep the hand wheel or wrench on the open cylinder valve at all times to allow prompt
emergency shut- off.
5. Inspect all connections for leaks, and fix any leaks. A leak detection solution may be applied
to the connections (if compatible with the application) which indicates leaks by bubbling. To
further check for leaks or if the leak detection solution cannot be used, close the cylinder
valve for a period of time (recommended 24 hours), and observe the high pressure gauge
for a drop in pressure. If so indicated, recheck the CGA connection and all other high-
pressure port connections. Never attempt to fix a leak under pressure. If leaks are detected,
depressurize the system, and retighten the connection. Begin again at step 3.
WARNING: While CONCOA assembles the AutoSwitch system components to exacting leak-tight
standards, the customer should also inspect for any loosening of internal parts that may occur in
shipping or installation by completing the pressure decay test detailed above. If all external leaks
have been found and corrected and the system still indicates a leak, disassemble the front cover
from the AutoSwitch after removing the eight screws shown in Figure 10. Check for leaks on the
system's fittings as described above.
6. Slowly turn the line regulator knob clockwise. This will increase the pressure of the line.
Adjust to the desired working pressure and again check for leaks using the methods
described above.
