Testing

1

Connect pressure gauge to test
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
