Hey i got a call tonight from a new customer. Ive never been there so I dont know for sure what the history of the Ice machine is. They say it's a ice-o-matic. I guess once is goes into harvest, some of the ice sticks and doesnt waanna fall. They have to manually chip it out. Before I go down there tomorrow I wanted to get some quick info maybe. I do Heating and Air conditioning, but now were getting into ice machines again. I'm sorry I can't give you anymore information than that. It's a R-404A. I more familiar with Scottsman Ice machines and flakers. But not to familiar with Ice-O-Matic. any helpful info would be appreciated.
