To clean the lubricator,water-valve 7 should be shut off, waste cock 14 opened,and the lubricator drained of its contents. All feedsshould then be opened, cleaning plug 22 removed, andwater-valve 7 and steam valve given their full would then pass down through equalizing tubes 17,forcing the contents out of the sight feed glass 9, throughthe feed nozzle 9-a and regulating valve 15, into the oilchannel and through the opening of cleaning plug 22.
