This should work...
<a href="URL TO PAGE 2">PAGE 2</a>
<iframe height="SET HEIGHT" width="SET WIDTH" src="PATH TO YOUR PDF DOCUMENT"></iframe>
Not sure what else is on, or going to be on, Page 1 but include link to your Page 2.
On Page 2 set your path to your pdf in the src then set your height and width as you want them. There are other iframe attributes you can set: http://www.w3schools.com/tags/tag_iframe.asp
when Page 2 opens the pdf should be displayed if the path is correct.
Hope this helps.
