Operating Instructions
Vacuum Sealing Food
Follow these steps to vacuum seal your food items:
- Prepare the Bag: Place the food item into a suitable size vacuum bag. Ensure the contents do not obstruct the air valve or the zipper area.
- Seal the Zipper: Use the provided sealing clip to firmly close the double zipper of the bag. Run the clip across the zipper multiple times to ensure a complete and airtight seal.
- Position the Sealer: Lay the bag flat on a stable, flat surface. Place the suction nozzle of the handheld vacuum sealer directly over the air valve on the bag. Ensure a tight fit.
- Start Vacuuming: Press the power button on the sealer to begin the vacuuming process. The device will start to remove air from the bag.
- Monitor and Stop: Observe the bag as it deflates. Once the desired vacuum level is achieved (the bag is tightly sealed around the food), press the power button again to stop the device.
