you use this the same as any other moka pot plenty of instructions on the web
i have one the same
fill lower chamber with water, to the bottom of the safety valve
fill coffee chamber with coffee, i overfill and wipe with crooked finger, this way the filter compacts the coffee properly.
coffee ground approx drip filter or medium to fine.
wipe gasket before putting together
place on stove top abnd medium heat and let it heat and bubble up
when the water boils in the lower chamber it uses the steam to force the water through the coffee
as with a conventional coffee machine the grind and quantity in the basket is critical
using the right blend/ roast produces a very nice coffee
cleaning with litlle bit of citric acid or lemon juice this time only
make a couple of cups to re oil surfaces and discard
normally wash after use in hot water,
