Abstract: A package terminal air conditioner having a modular blower and heater unit that is readily removable intact for servicing. The module includes a housing or box that has a back scroll portion and a pair of ends or side panels. The ends have rearwardly extending tabs and top forwardly extending mounting brackets. A cross-flow blower wheel is spaced adjacent the scroll portion of the housing and is supported by the ends. A shaft extending from the blower wheel is connected to a motor. An electric heating element is mounted to the housing, and the motor and heating element are connected to an electrical connector. The module is installed into an indoor section compartment of the air conditioner, and the tabs insert through slots in the main partition. The mounting brackets are then affixed and the connector is mated to a matching connector.
