Hi, swlz,
Here is a link:

If you scroll to the bottom of the above page, there is a toll free number; with information available from Product Specialists, as well as Customer Service. The search engine said this website has parts for a Muskin pool. They might have instructions for them as well.
I just finished tearing down our 24 yrs old, 15 x 30, above ground swimming pool, hauling it off, (3 pickup loads) to the local dump.
It was so old, no one wanted it!
I do wish you the best, and good luck with finding some instructions. If you can't find the specific instructions for that particular pool, then any instructions for an 18 ft round pool would help you. They are basically the same.
