Type of start up of unit
Automatic start

occurs by means of destroying the thermo bulb of the shut-off valve of the unit by an electromechanical inducer (one-shot device) when an electric triggering pulse is supplied from the fire control device;


Manual start

occurs by means of destroying the thermo bulb of the shut-off valve by an electromechanical inducer (one-shot device) when an electric triggering pulse is supplied from the starting device by pressing the button of the manual start.
