The temperature equalizer is in the fan which is mounted on the top of the evaporator plate. It is designed to keep air moving throughout the cabinet in order to maintain consistent temperature between the upper and lower half of the cabinet. During normal operation, set the switch to the "Auto" position. The fan will operate whenever the cooling system is running. To adjust for different temperatures between the top and bottom of the unit, the "Continuous" selection would be chosen. The "Off" position simply shuts off the fan for noise reduction. Do not become overly concerned about air temperature variations. Remember the unit measures liquid temperature, not air temperature. The unit will operate when the liquid temperature varies.
