Important: When used as the buffer tank in a constant pressure system tank precharge must be set according to system pressure setting for correct and efficient operation of the constant pressure pump. I have a table below with the tank air charge corresponding with system pressure for Grundfos SQE systems. You can also find this with your CU301 controllers manual. The tank charge can be checked and adjusted the same as a car tire with a tire gauge and air compressor. You can only check and adjust the pressure in the tank with the pump off and pressure let out of the water lines. It will be easier to add air to the tank before installation.              SQE System Tank Charge Table              Tank Air Charge - System Set Pressure(CU301)                                       28PSI - 40PSI                                       35PSI - 50PSI                                       42PSI - 60PSI                                       49PSI - 70PSI                                       56PSI - 80PSI                                       63PSI - 90PSI                                       70PSI - 100PSI
