Set up condensore with fan in a place it won't cut off your hand ...........
Guards are not overated
Run poly feed to bottom and return to the top of opposing side seal all penetrations and make sure you can open it to keep full
insulate poly and hook up like standard water, you will however have to insulate the board as you will have condinsation.
Insulating will prove the be the difference in epic and fail
get the best pump you can afford as this solution will have a higher viscosity than plain water making the pump work a bit harder for a living
turn on and have some sub ambient fun
