Ventilation Requirements
The RealScan 7875 is designed to operate without an exhaust fan in the checkstand; however,
there must be adequate convection airflow. The ambient temperature inside the checkstand
cannot be higher than 40° C (104° F). Also, the ambient temperature inside the checkstand
cannot be higher than 7° C (12.6° F) above the ambient temperature outside the checkstand. For
example, if the ambient temperature outside the checkstand is 24.4° C (76° F), the ambient
temperature inside the checkstand cannot be greater than 31.4° C (88.6° F). If the checkstand
contains other heat producing equipment, you may need to use forced air to keep the temperature
within the specified range. However, air coming into or leaving the checkstand MUST NOT
enter or exit past the RealScan 7875.
