10. Advanced Brewing and Operational Techniques
1. It will take about 18 minutes for the digital display and pressure gauge to
show that both boilers are up to the set temperature. If you want to brew right
away, we recommend doing 3 separate 4-ounce blank shots to preheat the
brew group and portafilter. To pull a blank shot, place your portafilter into the
brew group and raise the control lever to the UP position and run 4 ounces of
water through it. If the temperature falls below the set point, wait for it to heat
back up and then repeat this procedure.
2. After the machine has been on for over 35 minutes, it is recommended that
you run 2 ounces of water through the brew group if the machine has been
idle 5 minutes or more.
3. After the programming the machine to brew at a different temperature, it may
take 5 to 10 minutes for the boiler temperature to balance out.
4. The Brewtus has two 1.7-liter boilers, one for brewing and one for steaming
and dispensing hot water. When the Brewtus is turned on, the steam boiler
will automatically fill with water. The brewing boiler must first be filled by
lifting the control lever and leaving it in the UP position until the water is
flowing out of the brew group in a steady stream. When the steam boiler is
full, the heating element in the steam boiler will be energized and the steam
boiler will start to heat up. Once the steam boiler reaches operating pressure,
which is around 1.3 Bars on the gauge, the heating element in the steam boiler
will turn off and the heating element in the brewing boiler will turn on. As the
brew boiler heats, the small LED on the digital display will flash and will
display the current temperature of the boiler. The steam boiler will heat in
around 8 minutes and the brew boiler will heat in another 8 minutes.
