  • Patent number: 6370899
    Abstract: A single package wall mounted HVAC unit comprising a cabinet assembly including a primary cabinet subassembly, a back panel subassembly adapted to close the open back of the back panel subassembly, and cabinet connection means for removably attaching the primary cabinet subassembly to the back panel subassembly so that the back panel subassembly can be attached to the wall of a structure and then the primary cabinet subassembly can be positioned on and attached to the back panel subassembly. Also disclosed is a blower mounting arrangement for selectively mounting the air circulation blower within the cabinet subassembly in different positions to attenuate the blower noise transmitted to the conditioned space. An interlock is disclosed for the control box to prevent the control box cover from being removed without disconnecting the HVAC unit from the power supply.
