never had a chiller before...got an amazing deal on the weekend from a company that maintains and sets up tanks selling their equipment off... i ended up with a 1/2 hp chiller....

i plugged it in before plumbing it and the display came on....i half expected it to i start running.... on the front is a display, an up and down button for temp and a set button, on the side an on/off switch and fuse....i moved the temp right down to 50 and still nothing... should it have come on or does it need water going through it to do so
thanks
