There are a number of downloadable files on this site that are in .PDF format (Portable Document Format). Many of the hydraulic curves, the IOMs and PumpLines fit into this category.
This format is increasingly common on the internet, and allows the user to both see the document on screen, as well as print the document retaining the original formatting.
In order to view these files, you must have the Adobe Acrobat viewer installed on your system. This is a free viewer that is downloadable from the Adobe Web Site (click on the icon below).
Adobe recommends users view PDFs with the 3.0 or higher version of Internet Explorer, Netscape Navigator or AOL browser. Once you have downloaded and installed Adobe Acrobat Reader, you should be able to view the PDF automatically in the browser window when you click on the PDF link on a Web site.
