<P>PROBLEM TO BE SOLVED: To provide a condenser vacuum adjustment device capable of performing proper vacuum adjustment of a condenser in a short time period, while utilizing existing methods and mechanisms. Ž<P>SOLUTION: The condenser vacuum adjustment device 10 includes a vacuum adjustment mechanism 11, air ducts 12, 13 for establishing connection between a condenser 102 and the condenser vacuum adjustment device 10, and valves SV1, SV2 for functioning as a stop valve mechanism provided between the air ducts 12 and 13. The vacuum adjustment mechanism 11 can perform fine adjustment in air supply environment for causing the condenser 102 to become proper vacuum by disposing a valve group consisting of a plurality of valves NV1 to NV8 for air supply that is more effective in fine adjustment than the valves SV1, SV2, and opening a predetermined number of valves. Whereby, when the valve SV1, SV2 are fully opened, air supply environment, which has been fine adjusted by the vacuum adjustment mechanism 11, is transmitted to the condenser 102.
