Ventilation Requirements
The RealScan 7882 Scanner/Scale is designed to operate without an exhaust fan in the
checkstand; however, there must be adequate convection air flow. The ambient
temperature inside the checkstand cannot be higher than 104° F (40° C). Also, the
ambient temperature inside the checkstand cannot be higher than 12.6° F (7° C) above
the ambient temperature outside the checkstand. For example, if the ambient
temperature outside the checkstand is 76° F (24.4° C), the ambient temperature inside
the checkstand cannot be greater than 88.6° F (31.4° C). 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 7882 Scanner/Scale.
