This is a frozen Coffin Case in the Market Dept. Left Side Half of the Evaporator was severely frozen up, with ice extending 2-3 inches above the bottom Evaporator cover. I valved off the liquid line and ran a hose overhead to the Market Hot Water Outlet. Washed the coil thoroughly a d removed all the Ice. Reinstalled the Fan And coil Cover and restarted the case. Is a Dual Temp Case set on Medium Temp. Regarding why it froze up, based on the pattern of the ice it had been accumulating for weeks or months to have become the size that it is. After looking at how the other cases next to this one are being stocked,  well above the stacking limit line, it is likely that the overstocking is the reason that the cases at times freeze up this bad. We recommend to make sure that all the coffin cases not be overstocked to the point of obstructing the airflow from maintaining it air curtain above the food. Disruption of this air curtain allows more humidity into the case than its designed for, leading to excessive freeze ups. 
Case working again.
