This InSinkErator CC-202 control center will help you save water and energy. The automatic reverse control helps to boost the capacity of the cutting elements by preventing unwanted jams in the disposer and keeping the disposer's grinding elements last long. It actually gives 5-second reverse delay to avoid motor damage. The function of this control center doesn't stop after the grinding process or the motor is turned off. It has the so-called water shut-off delay (post flush) that lets the water flow for another 10 minutes, flushing away all food waste from the drain line. This CC-202 model is a NEMA 4 rated unit and constructed of stainless steel (outdoor/indoor use) to give necessary protection against particles and/or elements that can fail in other lower quality systems. This CC-202 is backed by InSinkErator's 1-year standard warranty.
