                        The 3030-400 Series Uni-Kits® feature a constant cut-in at 39°F. This constant cut-in on every cycle provides automatic defrost while maintaining food temperature at a safe level. Turning the dial will change the differential between the cut-in and cut-out temperatures, with cut-in always remaining fixed at 39°F. The 3030-400 Series Uni-Kits are available in a wide selection of temperature ranges and capillary lengths to fit virtually every replacement application. Uni-Kits include all necessary adaptor mounting brackets, dial shaft adaptors, dial drivers, mounting screws and installation instructions.Features and Benefits Individually boxed in a strong corrugated carton for extra protection from damage during handling or shippingComplete label information - O.E.M. name and O.E.M. part numbers for handy referenceDetailed instructions for trouble-free installationU.L. and C.S.A. listed
