5. Operating Instructions
5.1 General Vacuum Sealing
- Plug the appliance into a power outlet.
- Prepare your vacuum bag: Use the built-in cutter to create a custom-sized bag if needed, then seal one end using the 'Seal' function.
- Place the food item(s) into the bag, ensuring at least 1.5 inches (38mm) of clearance from the bag opening to prevent wrinkling and ensure a secure seal.
- Open the lid of the vacuum sealer.
- Place the open end of the bag within the designated vacuum chamber channel (under the green baffle for vacuum, red baffle for seal only).
- Close the lid cover and press down firmly on both sides until you hear a 'click' sound, indicating it is locked. The display should show '88'.
- Select the appropriate food mode (Dry/Moist) and bag type (Thin/Medium/Thick) if necessary.
- Press the 'Vac Seal' button to start the vacuuming and sealing process. The machine will automatically vacuum the air out of the bag and then seal it.
- Once the process is complete and the indicator lights turn off, press the release buttons on both sides to open the lid.
- Remove the sealed bag.
