Older spa Lover

I have a 1992 Hot Springs Sovereign Spa. Until recently I was able to maintain it quite well. But I think that I need to replace the circulating pump and I need to get the pump ordered and the schematic on the rest of the parts. Could someone help me out with copying or sending me a manual. I have looked everywhere and I can't seem to find one to download. If you don't have a manual could you direct me to the place I can go to get one. Thanks so much...Old Spa Lover
