Developed upon feedback directly from customers and installers, the unit incorporates a variety of high end componentry at an affordable price point. The SC Series is a direct replacement for one of the most well known cellar cooling units, the XLT. Just like the series it replaces, the units come in 5 models that effectively cool a 350 to 2000 cu. ft. properly insulated environment. Designed for simple through-the-wall installation, the unit fits between standard wall studs and a single piece mounting bracket eliminates the need for a support shelf. The SC has a 30°F temperature differential. In order to keep your cellar at 55°F, the area the unit exhausts into should not exceed 85°F. This makes interior installation ideal for SC series units. 14.25" X 15.75" X 17.5"
