Schenck Process spray bars

Hello fellow engineers. Am selasi and currently a site engineer on a project in west Africa. I just joined this website which am really impressed with trend of discussions.

I have this problem currently on site and need suggestion to handle it. I will like to know if spray bars for Schenck Process Double Deck Horizontal Screen (SLK3061) are permanently fitted to the main frame of the screen or is independent of it. I believe some of the engineers in this forum may have worked on this equipment before and will be ready to help me out.
