I bought a used Aquatic Hot Tub. I don't know what model that i have. The only thing that I see is a date on the electrical box cove. It says 08/92. It is octagon and is I would say a six person tub. the control panel says Jets, Blower, lights, Warmer, Cooler. It also has two dials one on eaqch side of the control panel.How do I find out what model that I have, to get a manual for it.Thank You Tony Dottore
