Operating Instructions
Basic Operation
- Add Ingredients: Place desired food and liquid into the inner pot. Ensure the total fill level does not exceed the MAX line (2/3 full for most foods, 1/2 full for expanding foods like rice or beans).
- Close Lid: Place the lid on the cooker, aligning the arrow on the lid with the arrow on the base. Rotate the lid clockwise until it locks into place. Ensure the steam release valve is in the "Sealing" position.
- Select Program: Press the desired program button (e.g., Chicken, Rice, Stews). The default cooking time for that program will appear on the LED display.
- Adjust Time (Optional): Use the "+" and "-" buttons to adjust the cooking time if needed.
- Delay Timer (Optional): To delay cooking, press the "Delay Timer" button, then use "+" and "-" to set the delay time (up to 2 hours). The cooker will start automatically after the delay.
- Start Cooking: Press the "Start/Stop" button to begin the cooking cycle. The cooker will preheat, build pressure, and then begin the countdown.
- Pressure Release: Once cooking is complete, the cooker will automatically switch to "Keep Warm" mode. To release pressure, carefully turn the steam release valve to the "Venting" position using a utensil (not bare hands) to avoid steam burns. Wait until the float valve drops before attempting to open the lid.
- Open Lid: Once pressure is fully released and the float valve has dropped, rotate the lid counter-clockwise and lift it away from you to avoid residual steam.
Browning Feature
The browning feature allows you to sauté or brown ingredients directly in the inner pot before pressure cooking.
- Add a small amount of cooking oil to the inner pot.
- Press the "Browning" button.
- Add ingredients to brown. Stir occasionally.
- Once browning is complete, press "Start/Stop" to cancel the browning function. You can then proceed with adding other ingredients and starting a pressure cooking program.
Keep Warm Function
After the cooking cycle finishes, the unit automatically switches to the "Keep Warm" function, maintaining food at a serving temperature for up to 3 hours. To manually activate or deactivate, press the "Keep Warm" button.
Maintenance and Cleaning
Regular cleaning ensures optimal performance and longevity of your pressure cooker.
- Unplug and Cool: Always unplug the appliance from the power outlet and allow it to cool completely before cleaning.
- Inner Pot: The non-stick inner pot is removable and washable. Wash with warm, soapy water and a non-abrasive sponge. Rinse thoroughly and dry completely. Do not use harsh abrasive cleaners or metal scouring pads, as these can damage the non-stick coating.
- Lid: Wash the lid with warm, soapy water. Pay attention to the gasket and steam release valve area. Ensure all food particles are removed. Rinse and dry thoroughly. The sealing gasket should be inspected regularly for cracks or damage and replaced if necessary.
- Main Unit: Wipe the exterior of the main unit with a damp cloth. Do not immerse the main unit in water or any other liquid.
- Steam Collector: Empty and clean the steam collector after each use.
- Storage: Store the cleaned and dried pressure cooker in a dry place. You may store the lid inverted on the inner pot to prevent odors.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Cooker not building pressure. | Lid not properly closed or sealed. Steam release valve in "Venting" position. Insufficient liquid. | Ensure lid is locked and steam release valve is in "Sealing" position. Add more liquid if necessary. Check sealing gasket for proper placement or damage. |
| Steam leaking from lid. | Sealing gasket improperly seated or damaged. Food debris on gasket or rim. | Check and reposition the sealing gasket. Clean the gasket and rim of the inner pot and lid. Replace gasket if damaged. |
