Ask 'Dr. Spa' Q & A Message Board

I have a very old Jacuzzi hot tub that I cannot identify. I think it's a late 1970's or early 1980's model. It's a smaller, oddly shaped, 6-sided model with a very thick acrylic tub and stained wooden sides. I assume it's a Jacuzzi brand because the spa side switches on the top lip say Jacuzzi on one of the three switches in the cluster. It is so old, the pump/blower/filter assembly is external to the tub on one side with a small "dog house" cover. The controller is a model A-110 by FPI Spas. The Blower is Santana by Conger Bros. The motor is by GE with a Jacuzzi pump attached to one end. The filter assembly is a CFT series by Jacuzzi. I am looking for an owner's manual so I can figure out an unattached 1/4" airline which has been capped of goes to an exposed hole in the pressure side of the blower outlet pipe or if I am missing something else. Also, I would like to replace the light bulb socket assembly in the footwell. I have photo's of everything on my Mac but I can't seem to figure out how to attach them to this post. If you can advise me how to post the photo's, I'll do do. Please pardon my ignorance of this procedure.
Yours truly,
John Kampf
