4.1 Location Considerations
For a downflow unit, the unit can sit on an accessible, elevated flooring system. It may be necessary to
furnish additional pedestal support below the unit to ensure maximum structural support. A separate floor
stand for the unit may be used as support, independent of the elevated floor and installed prior to the
flooring system.
For downflow and upflow units, provide approximately 34" (864mm) service clearance on the left, right and
in front of the unit whenever possible. The minimum space required for service is 18" (457mm) on the left
end, 18" (457mm) on the right end and 24" (610mm) in front of the unit. This space is necessary to permit
routine maintenance, such as replacing filters and adjusting the fan speed. On downflow and upflow
CW106 and CW114 models, left-end and right-end minimum clearances are 0" (0 mm), with the exception
of rear return.
Avoid installing units in an alcove or at the extreme end of a room that has a high aspect ratio (long narrow
room). Also avoid installing units too close together. This tends to reduce the effectiveness of the air
distribution as compared to units located 30-40 feet (9-12m) apart.
