Abstract
In a space conditioning system, such as a central air conditioning or heat pump system, a unit of the system has a heat exchanger made of a predetermined first type of metal (e.g., aluminum) and a cabinet in which the heat exchanger is mounted, which is made of a second type of metal (e.g., steel). A device is provided for isolating the heat exchanger from the cabinet to prevent contact therebetween. The isolation device preferably includes plural snap-fit plastic members spaced along the top and bottom of the heat exchanger, plural mounting brackets made of the first type of metal on each end of the heat exchanger and a pair of plastic bushings operatively associated with each mounting bracket and extending through aligned holes in the corresponding mounting bracket. The bushings are adapted to receive an attachment member, such as a screw, made of the second type of metal, so that each attachment member extends through the bushings and aligned holes in the corresponding mounting bracket to attach the mounting bracket to the cabinet without the mounting bracket contacting any part of the cabinet or the attachment member. In preventing direct contact between components having dissi…
