Abstract
In a first intense suction, a supply line K is subjected to suction by a suction pumpwith a portion of the supply line K held in a blocked state. Subsequently, the blocked portion of the supply line K is opened and trapped bubbles are discharged from a pressure chamber, which is located relatively upstream. In a subsequent second intense suction, the suction by the suction pumpis performed on the supply line K with a portion of the supply line K held in a blocked state, until a maximum negative pressure smaller than a maximum negative pressure of the first intense suction is obtained. The blocked portion of the supply line K is then opened, thus discharging trapped bubbles from an upper filter chamber, which is located relatively downstream.
