Safety valve test
Safety valve test as follows:
• Depressurise the system.
• Turn the adjusting screw of the final pressure switch one
turn clockwise (please see chapter “Final pressure switch“,
page A-47).
• Start the compressor.
• Watch the final pressure gauge. The safety valve should
open when reaching working pressure of the compressor.
If not, switch off the unit and take out of service until the
safety valve has been replaced.
• Switch off the compressor.
• Turn the adjusting screw of the final pressure switch back
(one turn counterclockwise).
• Check the cut-out pressure. Readjust if necessary!
The safety valve test is now completed.
