When the maximum level of accumulated grease is reached, Grease Alarm activates the automatic disposal mode. First of all, the mixer is turned on for blending grease, water, and solid layers. Then the Disposal Pump is actuated for emptying of the separator. After complete disposal, the separator can be rinsed by freshwater which is filled through the Refilling unit, mixed, and emptied by the Disposal Pump. After rinsing, the separator is filled up completely with fresh water.
