On the evaporator, the water should enter the bottom and exit the top. The refrigerant should enter the top and exit the bottom.

At 4F, the delta-T is low. It should be about 10F. Either the evap outlet superheat is too high or there is too much water flow.

I'm thinking there is a combination of several problems... and we need to track them down one at a time.
