mmml M©<m@Mm I EC and ECP Series General Operation A general description of how the C, EC and ECP series cubers work is given below. The remainder of the manual provides more detail about the operation and troubleshooting of these machines. With the ICE/OFF/WASH switch in the ICE position, the compressor, water pump, and condenser fan motor (air cooled machines only) will energize starting the freeze cycle. During the freeze cycle water is circulated over the evaporator(s) where the ice cubes are formed. When the suction pressure has pulled down to the proper cut-in pressure of the timer...
