9. Mm GENERAL INFORMATION The VERSUS GAS Sequential system is the best solution for the latest generation fuel injected vehicles The VERSUS GAS name represents the most advanced level of development of the CNG LPG conversion systems in the industry The VERSUS System is fully automatic and maintenance free It immediately switches to gasoline when your CNG LPG tank is empty After refueling at least a half tank it automatically switches to the CNG LPG supply In the event of a failure of any component or leakage of the system it automatically disconnects all the valves and switches to gasoline Practically the only required element of VERSUS operating system is its regular service at an authorized workshop All key elements of the VERSUS System meet the safety requirements of the regulations ECE110RO0O ECE67RO1 and NFPA 52 n This manual almost entirely describes the possible scenarios the user may face and the safe operation of the VERSUS system Before using your new CNG LPG fueled vehicle please read and study this manual and its contents If in any doubt please ask the installation shop staff i for a detailed explanation of the operation of your new VERSUS GAS system mg Zanen g a 8 a k 4 A S A bh a S i i es Tank Container J i WE MAP Sensor XFP1 5 a Multivalve l e Gas Supply Pipe Io l i ECU VERSUS For more information about the SGI VERSUS GAS syst
