Lockhart made a cooler with a built-in thermostat but because of the tight
space to fit the Virago it required an external unit. For what it's worth,
being the pack rat that I am, I had saved the original box and the
installation instructions. Attached are a couple files I scanned from the
instructions. Don't know if this helps any since it was off the shelf but
let me know if you want any more of the instructions scanned and I can send
them. The application required modifying the plastic cowling around the coils.
