connection P1

Test connection P1 is either at the front of the compressor, in front of boiler V1 or at the back at the overflow valve.

2

Let compressed air out until 0 bar is reached by operating hand brake lever several times

3

Pump system up from 0 bar to 12 bar

Compressor switches off. Time difference between 0 bar and 12 bar must not exceed 6 min +/- 1 min.

In case of insufficient operation

Adjust overflow valve by measuring the release pressure (boiler V1 filling)

Specified value 9.6 bar - 0.3 bar
