Hefei Light Source (HLS) has been operated for more than twenty-five years. From 2010 to 2014, the upgrading project of HLS has been carried out and the new machine is called HLS-II. The main improvement include: the emittance is reduced to 40 nm·rad, 3 new insertion devices (2 IVU and 1 EPU undulators) are added and the injection energy increases to 800 MeV. The typical life time is 300 mins at 300mA, 800 MeV. The average pressure of static and dynamic vacuum are below 2·108 Pa and 1.2·10-7 Pa respectively. The design, installing and commissioning of the vacuum system of the storage ring are detailed stated in in this paper.
