3.2 Considerations for Air Distribution
Depending on the intake/discharge configuration of the unit, consider the following when preparing for
installation:
When installing a downflow unit with raised-floor discharge:
• Verify that the raised floor is properly sized for the unit’s airflow and the room is free of airflow
restrictions.
• Perforated floor tiles in the raised floor should ensure minimal pressure loss.
• The raised floor must provide a minimum of 7-1/2in. (191mm) of clearance.
• Ensure that there is adequate clearance above the unit for return air. See DPN002936 in the
Submittal Drawings on page106.
When installing a downflow units with floor-level discharge:
• Provide several feet of clearance for air discharge of the unit.
• Ensure that there is adequate clearance above the unit for return air. See DPN002944 in the
Submittal Drawings on page106.
When installing upflow units
• Provide several feet of clearance for intake and discharge of the unit or for supply and return
ducting.
• Provide clearance for service access. See DPN002937 in the Submittal Drawings on page106.
