Page 4: Safety Information
☞ Read and obey this manual before installing or operating the equipment. Use the equipment for the intended use only (for measurement and control of vacuum). Operate the controller only in combination with VACUUBRAND genuine accessories (e. g. isolation valve, vacuum management module VMS A). Make sure that the individual components are only connected, combined and operated according to their design and as indicated in the instructions for use. - Page 5 page 5 of 36 Adopt suitable measures to prevent dangers arising from dangerous or explosive gases and dangers arising from the formation of explosive fluids or explosive or flammable mixtures and ensure that the materials of the wetted parts are compatible, see section “Technical data”.
