PRODUCT DESIGN
3 Rev. 1
BBA blower cabinets are designed as a two-piece blower coil. The BBA blower section can be attached to a CCA_FC_,
CHA_TC_,orCHF_TC_ cased evaporator coil. This two piece arrangement allows for a varietyofmix-matching possibili-
ties providing greater flexibility.
The BBA blower cabinets can be positioned for upflow, counterflow, horizontal right or horizontal left operation. All units
are constructed with R-4.2 insulation. In areas of extreme humidity (greater than 80% consistently), the installer should
insulate the exterior of the blower with insulation having a vapor barrier equivalent to ductwork insulation, providing local
codes permit.
