OPERATION REMINDERS
- Do not overfil the vacuum bag, allow at least 1.6 inches of space between the vacuum bag’s contents and the top of the bag. This ensures the open end of the vacuum bag can easily be inserted into the vacuum channel
- Keep the open end of the vacuum bag dry. A wet open end may compromise the sealing process.
- Perishables need to be appropriately refrigerated or frozen. Vacuum packaging can prolong the shelf life, but it cannot guarantee food will remain fresh indefinitely.
- Before vacuuming and sealing, clean and flatten the open end of the bag; ensure there are no wrinkles or foreign items at the open end. Keep the bag as flat as possible during the vacuuming Do not let sharp items puncture the vacuum bag.
- When vacuuming items with sharp edges (dry spaghetti, silverware, etc), wrap the sharp items before vacuuming. Sharp items are better stored in a jar or other external container instead of a bag
- Liquid contents must be cooled down before vacuuming.
The hot liguids will burn during vacuuming. So, hot liquids should only be sealed in a jar or canister. - For best performance, we recommend allowing the machine to rest for 1 minute after each use.
Clean any excess liquid or food residue in the vacuum channel before the next use. - During the vacuuming process, a small amount of liquid or food residue may be drawn into the vacuum channel. This may block the vacuum pump and cause the machine to malfunction.
To avoid this, put some tissues or a filter in the vacuum channel. Or, clean the vacuum channel before use
MAINTENANCE
- Unplug the machine first before cleaning.
- Do not immerse the machine in water or any liquids.
- Do not use abrasive cleaners to clean the machine, it is easy to scratch the surface.
- Use a wet cloth or a sponge dipped in mild soapy water to clean the exterior of the machine.
- Clean the vacuum channel after each use; wipe off any food scraps or liquids with tissues.
- Dry out the vacuum channel after each use.
- Clean the vacuum channel regularly as pictured.
- If the seal rings are deformed or fall, pull the seal rings out of the slot. Then, replace the old rings with new seal rings by firmly press- ing them into the slots. Ensure they are securely inserted.
TROUBLESHOOTING
Vacuum Does Not Work
- Make sure the power cord plug is securely connected to the socket
- Make sure the power cord is intact.
- The machine will shut off if it is overheating. Restart the machine after 15 minutes of cooling.
Poor Vacuuming
- Please gently press the cover down during the first use to make sure the seal rings are completely installed.
- Ensure the open end of the vacuum bag is completely inserted in the vacuum channel.
- Check if the heating element and the upper seal ring are clogged with foreign items; ensure the bag is in the correct position.
- Ensure the bag is wrinkle-free and that the open end of the bag has no foreign items or liquids.
- The vacuum bag may leak. Check if the vacuum bag is leaking by keeping some air in the sealed vacuum bag then immerse it in water. If bubbles are coming out, that means the vacuum bag is leaking. Please use a new bag to replace the faulty one.
Melted Vacuum Bag
- If the vacuum bag has melted due to an overheating heating element, please open the cover to cool down the heating element for a few minutes.
