NOTICE
For switching the compressor off
“normally”,
use only the stop push-button (- 3 - Fig. 16), but
not the EMERGENCY STOP push-button. After
having been switched off, the compressor is
after-cooled for 30 seconds (soft stop).
Temperature start-up protection
The screw compressor unit will not start up if the
ambient temperature is lower than 33.8 °F.
