Chilled water should enter cooling coils at the base and exit at the top (counterflow to gravity) to maximize heat transfer efficiency, because gravity assists the water's rise and gives it extra time to shed heat; if water enters from the top, gravity's momentum causes it to move too quickly through the coil without giving up all its heat.

“it's good to have this connected so that the flow The coldest water is coming in and the height is water going in And it's entering through the base of the coil and passing through you'll get much greater efficiency [out] [of] this because it's going against The Force of Gravity so it gives a little bit extra time and just to give off its heat”
