List these equipments and instruments, and give it to the owner for signature and confirmation. All of the water use points, outlet, drains, and dead leg should have hand valves in proper positions. Remove any component from the system that is not compatible with passivation solutions. Isolating valves should be installed at the ends of inlet and return water hoses, and at any other places anticipated to have breaking points in the system. 隔离一一将需要进行酸洗钝化的系统与不能进行酸洗钝化的设备、仪表等隔离开（如流量计 等），并列出明细，请业主签字确认。所有的用水点、出水点、排污点和单流管在适当的位置 要有手动阀。移除任何不适合酸洗钝化的部件。进水回水软管上以及系统中任何可能有断点处 需安装隔离阀。 Installation - Connect the entire system
