Adjusting the filter saturation indicator for the grease filter You can set the filter saturation indicator to suit your cooking habits. The factory default setting is a cleaning interval of 30 hours. - Select a shorter time (20 hours) if you often fry foods. - We also recommend a shorter cleaning interval if you only cook occasionally. This will prevent grease buildup from hardening and making cleaning more difficult. - Select a longer cleaning interval of 40 or 50 hours if you use very little fat when cooking.  Press the On/Off button  to turn off the fan.  Tap the delayed shut down button  and the grease filter button  at the same time.
