Ventilation and Spacing
Product Reference Guide 2-9
• A source of air that provides adequate cooling by convective air flow.
If motors, conveyor belts, or other heat producing equipment are located
near the scanner, forced air ventilation may be required. In most installa-
tions, a 30 cfm (.84 cmm) axial fan should provide sufficient air move-
ment. If a ventilation fan is installed, one with a removable filter that may
be washed or replaced is recommended.

NOTE
DO NOT place the scanner in a close-fitting, fully enclosed checkstand. Pro-
vide a MINIMUM of 16 square inches (103.2 square centimeters) of air intake
from below the installation for sufficient convective cooling.
