**Because the heat of rejection varies during the ice making cycle, the figure shown is an average.
Ice machines, like other refrigeration equipment, reject heat through the condenser. It is helpful to know the amount of heat rejected by the ice machine when sizing air conditioning equipment where selfcontained air-cooled ice machines are installed.
