5) Ceiling penetrations shall be located between floor/ceiling trusses. 6) The CRD-1WT’s supplied without a factory supplied plenum box require a steel or ductboard plenum to be field installed (see pages 4 - 6). The CRD-2WT’s are always provided with a factory supplied plenum box. -

Hanger Method The hanger method is the standard mounting method for CRD-1WT’s. It may also be used in lieu of the base mount method (see below) with the CRD-2WT. However, the hanging wire or straps would have to be field supplied. - Page 4 Base Mount Method The base mount method is the standard mounting method for CRD-2WT’s. It may also be used on CRD-1WT’s with steel plenums that either have an insulation band or are duct mounted. An insulation band is used on units with steel plenums that have a width or height greater than 12 inches [305 mm](see Figure 7A or 7B for reference).
