Sfiatare la pompa per mezzo della valvola di sfiato sulla testa pompa. Contemporaneamente, aprire leggermente la valvola di mandata. Continuare a sfiatare la pompa, continuando contemporaneamente ad aprire la valvola di mandata. Chiudere la valvola di sfiato quando fuoriesce un flusso di liquido costante. Aprire completamente la valvola di mandata. Per ulteriori informazioni vedere pagina 51. Comprobar el sentido de giro correcto de la bomba en la tapa del ventilador del motor.
