This can be done using the 'Advanced Link' option on the 'Links' panel of a product or 'Link' option on a fragment:
* Save your PDF in your Site folder
* In the 'Links' panel, tick the 'Advanced Link' box ('Link' box on a fragment)
* Select the 'URL' radio button
* Paste the following in the URL field:
javascript:ShowPopUp('MyFile.pdf', 500, 600);
where 'MyFile.pdf' is the filename, '500' the width and '600' the height of the popup window
* Enter the text to display as the link in the 'Link Text' field
* On the 'General' panel, enter [LINK] into the 'Full Description' field on a product or 'Text' field on a fragment. This is replaced by the text in the 'Link Text' field
* Click 'Apply'
* To ensure that your file is uploaded to the site add it into the 'Design | Additional Files' list
