4. Setup and Charging
4.1 Initial Charge
Before first use, fully charge the vacuum sealer. Connect the provided USB charging cable to the charging port on the device and to a suitable USB power adapter (not included). The indicator light will show charging status and turn off when fully charged. A full charge provides approximately 60 minutes of runtime, capable of sealing up to 100 bags.
4.2 Preparing the Water Tank
The vacuum sealer features a visible water tank at the bottom. Ensure it is securely attached and empty before use. This tank collects any liquids drawn during the vacuuming process. Do not allow collected liquid to exceed the MAX line.
5. Operating Instructions
5.1 Preparing Food and Bag
- Place the food item into a HiCOZY vacuum sealer bag. Ensure the food does not exceed the fill line and that the area around the circular air valve is clean and dry.
- Close the zipper seal of the bag completely. Use the provided clip to ensure a tight seal and to help press out excess air before vacuuming.

- Place the vacuum sealer directly over the circular air valve on the bag. Apply firm, flat pressure to ensure a good seal between the sealer and the bag valve.
- Press the power button on the sealer. The device will automatically begin to extract air from the bag.

6. Care and Maintenance
6.1 Cleaning the Water Tank
After each use, particularly when vacuuming moist foods, detach the water tank from the bottom of the sealer. Empty any collected liquid and wash the tank with warm, soapy water. Rinse thoroughly and ensure it is completely dry before reattaching it to the main unit. This prevents liquid from entering the motor and ensures proper function.

6.2 Cleaning the Main Unit
Wipe the exterior of the vacuum sealer with a soft, damp cloth. Do not use abrasive cleaners or immerse the main unit in water.
6.3 Bag Care
The included BPA-free bags are reusable. After use, wash them with warm, soapy water, rinse, and allow them to air dry completely before storing. Ensure bags are fully dry to prevent bacterial growth and ensure effective re-sealing. These bags are suitable for use in dishwashers, microwaves (with the bag opened), and for sous vide cooking.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Sealer does not turn on. | Low battery. | Charge the device fully using the provided USB cable. |
| Bag does not vacuum properly. | Bag zipper not fully closed; air valve not clean; sealer not properly aligned; bag damaged. | Ensure zipper is completely sealed. Clean the air valve. Realign the sealer firmly over the valve. Use a new bag if damaged. |
