Simply place your flasks in the lower flask chamber below the investment mixing chamber. Add the correct amount of investment based on your flask sizes, start the vacuum pump (not included), open the water valve from the graduated water cylinder, and then start the adjustable speed mixing motor and set your timer. For multiple flasks units, you can electronically turn the table to align the next flask under the pouring valve. As the investment fills the flasks, turn on the adjustable vibration table under the flasks and you are done!
