API Bucket/Utility De-Icer - 250 Watt

OPERATION: Simply place the unit into the water that you wish to keep de-iced. Connect the cord to a properly grounded, GFCI-protected receptacle while observing the cautions above. The unit will turn on when the water temperature approaches freezing conditions and will heat the water 10 to 20 degrees Fahrenheit before turning off. Multiple thermostats within the unit monitor water temperature as well as guard against overtemp conditions. Please note: the unit will not turn on unless the water temperature is approaching freezing. If you wish to test the unit, you must place it in a freezer for 15 minutes to get it cold enough to turn on.
