VACMASTER DUO550 Duo Suction and Chamber Vacuum Guide

VACMASTER DUO550 Duo Suction and Chamber Vacuum Guide

Welcome!

Thank you for purchasing the VacMaster® DUO550 Chamber Vacuum Sealer. You are about to use one of the most powerful vacuum sealers available. With the help of the DUO550, you will now be able to keep food fresh for longer in the refrigerator, freezer, or pantry. The DUO550 effectively removes air and extends freshness up to five times longer than traditional methods.

Our versatile and convenient machine can also be used to preserve and organize other items, like keepsakes or small, easy-to-lose items. Your DUO550 will quickly become invaluable to all your packaging needs; it will never leave your countertop. The DUO550 is a chamber vacuum system, which offers two distinct advantages over non-chamber, external suction units. First, a much higher level of vacuum can be achieved, which means a longer shelf life for foods that you package.

Secondly, liquids and liquid-rich foods can be effectively vacuum packaged. Foods like fresh meats, fish, soups, stews, and marinated vegetables are packaged quickly with ease and no mess. The VacMaster® DUO550 is perfect for sous vide cooking. For your safety and protection, carefully read and follow this guide. For more information, please visit us at www.VacMasterFresh.com.

Important Safeguards

For your safety, always follow these basic precautions when using a VacMaster® DUO550 Vacuum Sealer:

1. Read all instructions in this User’s Guide before use.
2. Do not use the DUO550 on a wet or hot surface, or near a heat source.
3. To protect against electrical shock, do not immerse any part of the vacuum sealer, power cord, or plug-in water or any other liquid.
4. Unplug the machine before cleaning or when not in use.
5. To disconnect, unplug the power cord from the electrical outlet. Do not disconnect by pulling on the cord.
6. Do not operate the DUO550 if it has a damaged cord or plug.
7. Do not operate the DUO550 if it malfunctions or is damaged. Contact Customer Service at 800-821-7849.

14. Extreme caution and care must be used when sealing or handling any pouches/bags containing hot liquids.
15. Do not use outdoors.

Important Tips

• Vacuum packaging is not a substitute for canning. All perishables still need to be refrigerated or frozen.
• Follow all food safety regulations as outlined by the FDA at www.FDA.gov.
• Use only VacMaster® Vacuum Chamber Pouches, Bags, and accessories.
• Some fruits and vegetables may release gases, known as outgassing. When packaging these fruits and vegetables, outgassing can cause the vacuum to be gradually lost over time. Blanching or freezing before vacuum packaging helps prevent this from occurring.
• Delicate foods can be frozen before packaging to protect them from getting crushed by the vacuum.
• Use VacMaster® Bone Guards to cover an item’s sharp edges to prevent pouch/bag punctures.
• Allow foods and liquids to cool before vacuum packaging.
• Avoid overfilling the pouch/bag. Leave a minimum of 3” of space between the contents and the open end of the pouch/bag. This is called head space. This will prevent spills during the vacuum sealing process.
• To prevent wrinkles from forming in the seal, gently stretch the pouch/bag flat along the seal bar before closing the lid.
• VacMaster® pouches/bags are boilable, freezable, and microwavable. When microwaving, it is important to pierce or make a small cut in the pouch/bag.

8. Using the lid lift handles, close the lid.
9. Make the following control panel adjustments: a. Power: Turn machine “ON” b. Vaccum Level: Set vacuum level to “MAX” level (29” hg). NOTE: This is the most common setting. To adjust the vacuum pressure, press Vacuum Level to a lower setting. c. Seal Time: Set seal time to 3.5. NOTE: This is the most common setting. If the seal is incomplete or sealing thicker pouches, increase seal time in 0.5-second increments.
10. Press the “Start” button to begin the vacuum process. Press and hold down the lid until the vacuum engages.
11. Once the pouch is sealed, the machine will “beep” to signal the process is complete.
12. Using the lid lift handles, open the lid. NOTE: DO NOT touch the Seal Bar area, as it may be hot after use.
13. Remove and inspect the pouch.
    • a. Vaccum – Check the quality of the vacuum by looking at the tightness of the pouch and the product. Look for air pockets or leaks. If the product is not tightly packaged, vacuum and seal again.
    • b. Seal – Inspect the pouch seal. A positive seal will appear clear. If the seal is spotty or incomplete, increase seal time by 0.5 seconds. If the seal appears white or milky, decrease seal time by 0.5 seconds. Once the settings are determined for your application, vacuum and seal again.

Package Delicate Items Using the Vaccum Chamber

Delicate items, such as baked goods, fresh fruits, etc., can be crushed during the vacuum packaging process. To prevent this from occurring, use the lower Vacuum Level such as “Medium” (27.5” hg).

Marinate Food Using a Vacuum Chamber
Your DUO550 has a special marinating feature that allows foods to quickly achieve the optimum flavor infusion. While in the Marinate cycle, the DUO550 will alternate back and forth between a state of vacuum and a state of rest (no vacuum). NOTE: One cycle is 9 minutes (8 minutes vacuum and 1 minute rest with no vacuum). Each cycle after will add 9 minutes. Marinate cycle can range from 9 minutes (one cycle) to 99 minutes (11 cycles) based on the desired intensity of flavor.

1. Make the following control panel adjustments:
   • a. Power: Turn the machine “ON”.
   • b. Press the “Set” button until the Marinate Time lights are illuminated.
   • c. Using the Arrow buttons, set marinating time: i. “9” for the minimum marinating time. ii. “99” for the maximum marinating time. NOTE: Typical marinate time is “18” or 2 cycles.
2. Press the “Start” button to begin the vacuum process. Press down slightly on the machine lid until the vacuum engages.
3. Your DUO550 will alternate between vacuuming and releasing air. NOTE: The display will show both the remaining cycle time and a blinking light signaling the cycle is in process.
4. When the Marinate cycle is complete, the machine will “beep” and release the vacuum.
5. Using the lid lift handles, open the lid. NOTE: DO NOT touch the Seal Bar area, as it may be hot after use.
6. Important: After the Marinate cycle is complete, the pouch will NOT be sealed. If you want to vacuum package for refrigeration, freezer, or sous vide cooking. NOTE: The Marinate cycle can be canceled by pressing the “Stop” button.

Troubleshooting

The DUO550 will not turn ON:

• a. Make sure the unit is plugged into a grounded outlet.
• b. Make sure the outlet is working.
• c. Check the power cord for any tears or frays.
• d. Check the fuse located in the power cord connecting outlet.

Error code in the Digital Display:

• E01 – The DUO550 cannot achieve the preset vacuum level.
  • a. Close and hold down the lid during the vacuum cycle.
  • b. Make sure the chamber gasket is clean and not damaged.
• E02 – The DUO550 will not enter the sealing mode.
  • a. The lid must be in the closed position during the vacuum and sealing cycle.
    NOTE: To clear the Error Code, turn OFF the machine, then turn it back on.

The pouch/bag is not sealing properly:

• a. Push and hold down the lid during the vacuum cycle.
• b. Increase or decrease the Seal Time. A positive seal will look clear. If the seal is spotty, incomplete, wrinkled, white, or milky, cut the seal and restart the sealing process.
• c. When vacuum packaging moist/wet foods, create a second seal above the first seal to ensure a positive seal.
• d. For the best results, use VacMaster® Chamber Pouches/ Bags.

Loss of vacuum from the chamber pouch/bag:

• a. Check for any puncture holes in the pouch/bag. Cover any sharp item edges with a VacMaster® Bone Guard sheet and vacuum package in a new pouch/bag.
• b. Check the seal and adjust the placement and/or sealing time.

Cleaning and Care

• Disconnect the power cord from the electrical outlet by unplugging it. DO NOT disconnect by pulling on the cord.
• DO NOT immerse in water or spray directly with liquid.
• Check the Vacuum Chamber and Gasket making sure they are clean and free of debris. If needed use a clean cloth with mild soap.
  • a. Wipe the vacuum chamber clean.
  • b. Wipe the gasket clean.
  • c. Wipe the seal area clean.
    NOTE: Always leave the lid in a resting position when storing. DO NOT stack items on top of the lid or machine. If the lid is forced down, the gasket will become compressed and the DUO550 may not operate properly.
• DO NOT use any acetone-based or abrasive cleaners on the lid or other plastic parts. Only clean with a damp cloth and mild soap.
• Do not store the DUO550 outside.

Vacuum Packaging Guidelines

• Follow all food safety regulations as outlined by the FDA at www.FDA.gov.
• Vacuum packaging is NOT a substitute for canning.
• Vacuum packaging cannot reverse the deterioration of foods.
• Vacuum packaging is NOT a substitute for refrigeration or freezing.
• Some fruits and vegetables may release gases, known as outgassing. When packaging these fruits and vegetables, outgassing can cause the vacuum to be gradually lost over time. Blanching or freezing before vacuum packaging helps prevent this from occurring. NOTE: Due to the risk of anaerobic bacteria, soft cheeses, fresh mushrooms, garlic, and onions should never be vacuum packaged.
• It is critical that food handling and storage are maintained at low temperatures. You can reduce the growth of microorganisms at temperatures of 34°F or less. Freezing at 0°F will not kill microorganisms, but reduces the chances of them growing. For long-term food storage, always freeze foods that have been vacuumed and packaged. NOTE: Beef and other proteins may look darker after being vacuum packaged. This is due to the removal of oxygen and is not an indication of spoilage.
• All perishable foods must be refrigerated or frozen.
