PROGRAMMING
This is the third screen of the display:
BG1 Auto Bypass and Auto Flush
Line 1
indicates the brew group to be adjusted.
Line 2
indicates whether the automatic bypass is currently [ON] or [OFF].
This feature is only avail-
able on volumetric machines with bypass hardware installed.
Line 3
indicates the percentage of the shot that will be completed before the bypass turns on.
This
option only appears when the ‘Auto Bypass’ indicator on line 2 is set to [ON].
Line 4
indicates the option to do an automatic back-flush.
To program Auto Bypass, press the button associated with line 2. The indicator ([ON] in this case) will
begin to flash. Use the ‘
▲ ’ ‘ ▼ ’ buttons to select [ON] or [OFF]. Press the line 2 button again to con-
firm the selection. If the Auto Bypass on line 2 is set to [OFF], nothing will be displayed on line 3.
To set the percentage level on the bypass, press the button associated with line 3. The percentage
indicator will begin to flash, showing it is ready to be adjusted. Use the ‘
▲ ’ ‘ ▼ ’ buttons to set the de-
sired percentage, followed by the line 3 button once again to confirm the new setting. The bypass will
now turn on after the set percentage of the shot is complete.
The
Auto Flush
can be activated by pressing the button associated with line 4.
Volumetric
: If the machine has volumetric capabilities, the indicator lights on the button pad of the
brew group selected will all light up. Place the portafilter used for back-flushing into the selected brew
group and press any button on the lit pad. The machine will now back flush 10 seconds on, followed
by 10 seconds off for 5 cycles. While cycling, the button pad lights will go into chase mode to let you
know it is currently engaged in the Auto Flush process. Once the Auto Flush is completed, remove the
portafilter and thoroughly clean the diffuser screen. The machine is now ready for use.
Manual:
If the machine does not have volumetric capabilities, place the portafilter used for back-
flushing into the selected brew group and turn the actuator to the on position. The machine will now
back flush 10 seconds on, followed by 10 seconds off for 5 cycles. Once the Auto-Flush is completed,
turn off the brew group to allow it to reset, remove the portafilter and thoroughly clean the diffuser
screen. The machine is now ready for use.
The Auto Flush can be interrupted mid-cycle by pressing any button on the selected brew group’s
button pad (with a volumetric machine) or by turning the brew group actuator to the off position (on a
manual machine). Interrupting the program will cancel the Auto Flush process, turning the indicator on
the control panel back to [Enable], and resetting the program.
