Factory instructions??

[TOPORANGER]

I have a 1991 AS Excella 25. As part of getting it ready to hit the road I am going though mechanical systems either testing, up grading or repairing. Worked my way to the holding tanks. My AS has a street side sewer flusher hose connection. My AS owner's manual does not contain any info regarding the use of this item.

What are the factory instructions for using this flusher?

Not how you use it or modified it to remove the back flow air break device. Just the simple AS instructions. I have searched many threads here and did not find the answer. Lots of info on how it doesn't work, not worth the effort, broken back flow valve, or I use this, discussion. I like to start with the factory instructions and go from there.

Thanks
