Dimensional Data
Table 5 contains dimensions that vary from unit to unit,
marked with letters (A, B, C, etc.) in the figures. Depth, length,
and height dimensions do not include lifting lugs, the handle,
latch, or fastener extensions. For shipping dimensions, the skid

(102 mm) to the height.
For units with the optional plenum, the plenum can ship
separately. All openings are on the plenum are centerline. For

connections are optional. Please indicate on the unit submittal.
Unit sizes 018, 023, and 028 have a single mechanical access
panel in the bottom front and bottom back. (See Figures 16,
