Advanced Brewing and Operational Techniques
1. It will take about 18 minutes for both boilers to show on the digital display and
pressure gauge that they have reached the set temperature. At this point, the
brew group hasn’t had enough time to properly preheat itself. If you want to
brew right away, we recommend doing 3 separate blank shots of 4 ounces
each to preheat the brew group and portafilter. To do 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. Do this for a
total of three times.
2. If the machine has been on for over 35 minutes and sitting unused for over 5
minutes, it is recommended that you run 2 ounces of water through the brew
group.
3. After programming the machine to brew at a different temperature, it may
take up to ten minutes for the boiler temperature to balance out.
4. The “Brewtus” has two 1.7-liter boilers: one for brewing and one for both
steaming and dispensing of 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. When the steam boiler reaches operating
pressure (approximately 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 brewing boiler heats, the small LED on the digital display will
flash and will display the current temperature of the boiler. Both the steam
boiler and brewing boiler will take approximately 8 minutes to heat up.
