The manuals are more like a loose leaf binder collection of the equipment owners manuals (stove, refreigerator, a/c, furnace, etc.). There's not a lot of Sunline specifics except for a copy of the order sheet (lists model and options, etc.) and some Sunline tips sheets (copies of which are in Files Section). So, if you can find owner's manuals for your specific equipment models, either in the files section here, or elsewhere on line, you will have the closest thing available.
