Control panel
- Switch on the voltage. Check that voltage on LED (6) lights up. The message ‘Compressor off’
appears.
- Open air outlet valve (AV).
- Press start button (1) on the control panel. The compressor starts running and the automatic operation
LED (8) lights up.
- On water-cooled compressors: regulate the cooling water flow with the compressor running at
maximum speed. Adjust the water flow to obtain the most suitable air temperature at the element
outlet, i.e. between 2 and 7 ˚C (4 and 13 ˚F) above the relevant temperature in the figure below.
For optimum operation, the cooling water outlet temperature must never exceed the value specified
in section Compressor data.
Consult Atlas Copco if condensate should be formed during frequent unloading periods.
