9MAGIC VAC™ SelectCommercial Quality Vacuum SealerHints and Tipsn Juices and moisture in foods can prevent a good seal,therefore, we recommend to pre-freeze food for 1-2hours before vacuum packaging. An alternativemethod is to fold a paper towel. Fill the bag with foodand lay flat. Place the folded towel so it lies betweenthe top of the bag and the food. Ensure that the papertowel is below the sealing strip. When you vacuumseal, the paper towel will absorb the excess moisture.n Liquids need to be cooled before vacuum packing. Hotliquids will bubble up and over the top of the jar whenvacuum packed. Note: A jar attachment is necessaryfor sealing jars.n Use canning lids that have been checked for flaws. Tocreate and keep a good vacuum, soak lids in boilingwater for 3 minutes and rub a drop of mineral oil onthe gasket. This will lubricate and hydrate the gasket.After vacuum packing, you may use the metal rim thatcomes with the jar in order to hold the lid in place.This rim is meant to assist in keeping the vacuumsealed lid secure.n Store perishable foods in the freezer or refrigerator.Vacuum packing extends the shelf life of foods, butdoes not preserve them.n Many foods are sold pre-packed in commercial vacu-um bags such as cheese and deli meats. Now, you canmaintain the taste and freshness of these foods, by re-packaging with Deni Magic Vac™ Bags after the com-mercially packed bags have been opened.n Pantry items such as flour, rice, mixes for cakes andpancakes, all stay fresher longer when vacuum packed.Nuts and condiments maintain their flavor while ran-cidity is kept out.n For objects with sharp points and edges, such as bonesor dried pasta, pad the edges with paper towels tokeep them from puncturing the bag.n There are many non-food uses for vacuum packing.Keep camping supplies such as matches, first aid kitsand clothing clean and dry. Keep flares for auto emer-gencies ready. Keep silver and collectibles untarnished.n Fill a bag about 2/3 full with water, seal the end (don’tvacuum). Freeze the bag and use for ice in the cooler,or ice packs for sports injuries.Using the Deni Magic Vac above sea level (over 4800 ft)The Vacuum Gauge is a device technically working on a differential basissince it measures the difference between external pressure (room) and theinternal vacuum level. This means that, in the presence of the same inter-nal vacuum level, the vacuum gauge change from yellow to green willdepend on the external pressure. Thus, when using the Magic Vac abovesea level, the vacuum gauge might not turn totally green when reachingthe maximum vacuum level due to the altitude; however, this does notmean that the obtained vacuum value is lower than the vacuum achievedat sea level.
