OEM manual (§3-12 Filter Pump Problem Prevention): "The following steps will help prevent filter pump problems: 1. Make certain the charcoal filter is installed with the smooth side down and the arms on the frame are clamped down over the protrusions on the outside of the frame. 2. The filter valve is to be closed at all times during frying." Filter envelope requires replacement every 10-12 filterings per §3-13.
