Filler plug, GX 7 and GX 11
Testing
The valve can be tested on a separate compressed air line.
Before removing the safety valve, stop the compressor (see Stopping), close the air outlet valve, switch off
the voltage, open drain valves (4) (tank-mounted units) and the manual drain valve (5) (if fitted - on floor-
mounted units) and unscrew filler plug (3) one turn to permit any pressure in the system to escape.
If the valve does not open at the set pressure stamped on the valve, replace the valve.
No adjustments are allowed. Never run the compressor without a safety valve.
