Section 2InstallationLocation of Ice MachineThe location selected for the ice machine must meet thefollowing criteria. If any of these criteria are not met, selectanother location. The location must be indoors. The location must be free of airborne and othercontaminants. The air temperature must be at least 35 F (2 C), but mustnot exceed 110 F (43 C). The location must not be near heat-generatingequipment or in direct sunlight. The location must be capable of supporting the weight ofthe ice machine and a full bin of ice. The location must allow enough clearance for water,drain and electrical connections in the rear of the icemachine. The location must not obstruct airflow through oraround the ice machine (condenser airflow is in andout the front).
