Owner's Manual The Duovac Symphonia Central Vacuum System features a large ultralight brushed aluminum dustbin that is user-friendly, coming equipped with easy-to-use handles and latches for quick emptying. The dustbin carries up to 33.8 liters, meaning you won’t have to empty it frequently. When maintenance is required, its LED maintenance indicator will alert users for increased durability of the motor. The Duovac Symphonia gives you the convenience of using it with or without a filtration bag. This central vacuum system executes double filtration when used without a filtration bag and can carry an additional 30 liters of dirt, and dust. This central vacuum system takes advantage of an innovative and ecological anti-bacteria treatment called SILPURE to eliminate odors from the filter. The filter itself is non-toxic and machine-washable, so you can toss the filter into your washing machine and save yourself the hassle of cleaning it by hand. The Duovac Symphonia has a warranty for 25 years. For the first 5 years, labor costs for necessary repairs are also covered.
