it goes like this: the IC still has hose water pumping through it. None of that is disturbed. What I did was to take a piece of copper tubing, bend it to a specific shape, then attach it to the IC with a couple zipties. Then, there's a small length of hose attached to the "in" of the recirc arm, with a CPC QD on it. So, I put the IC into the wort 15 mins before flameout, as usual. When the burner goes off, I turn on the garden hose and the IC starts to chill the wort. I let it go for a minute or so because I don't want pure boiling wort in my march pump. Then, I attach the "in" line of the march pump to my kettle valve, open the kettle valve and gravity pulls the first bit of wort down to the pump. I hook up the "out" line from the pump to the recirc arm. Then, I turn the pump on. What this does is pump wort from the bottom of the kettle, up through the recirc arm, and then back into the kettle, against the IC, and starts a whirlpool action in the kettle wort. This increases the efficiency of the IC. When I'm at my pitching temps, I turn the pump off, unhook the CPC QD from the recirc arm and place it into the mouth of the carboy, and turn the pump back on...voila, it pumps the wort into the fermenter for me.
