How do I install and set up the Miller Coolmate 4?

Select the proper coolant from Section 4-3 and fill the tank, maintaining the coolant level at approximately 1 inch from the filler neck. Connect the coolant hoses (with 5/8-18 left-hand threads) to the Coolant In and Coolant Out fittings, not to a water valve if present on the power source. Plug the unit into a 115 Volt AC grounded receptacle on an individual branch circuit capable of carrying 15 amperes. The unit turns on automatically when plugged in.
