Drop the washable, reusable cloth covered filter into the infusion chamber with the chain hanging down into the glass siphon tube. Pull the chain down until you can hook it to the bottom of the siphon tube. Fill the bottom carafe to the 5 mark with hot water and place 5 measuring spoons of coffee in top chamber. This model works on gas and electric rangetops, and comes with a wire diffuser for use on electric coil burners. Use medium-high heat. It takes about 4 minutes to heat the water, all the water is siphoned to the top chamber and then allow 2 minutes to brew. Once you remove from the heat source, the coffee comes back down to the bottom carafe. Remove the top, placing it in its convertible lid/stand, and bring the pot to the table for serving.

Stovetop coffee vacuum brewers do not come with thier own source of heat, but rather are used on a stovetop, either gas or electric, and tend to have a little quicker brew cycle than table top vacuum brewers due to the higher obtainable tempertaures using a stovetop.

Coffee Vacuums work off of air displacement, tiny bubbles that form in the bottom chamber when the water starts coming up to temperature force the water from the lower bulb to the upper bulb, where the water gets mixed with the coffee grounds, steeps a bit, then, when removed from heat, gets drawn back down through the filter into the lower bulb due to the vacuum that gets created when cooled. vacuum.

The entire process is fascinating to watch, and provides an excellent cup of brew. The brewed coffee in a vacuum is never directly exposed to heat.
