PROGRAMMING
There are 3 menu levels accessible to technicians. Menu level 2 may only be reached from level 1
and level 3 may only be reached from level 2.
To access menu level 2 - From the ‘Temperature Overview’ screen, press and hold both the line 4
button and up arrow, for approximately 4 seconds. The screen will cycle to the ‘Temperature Display’
screen. This is screen 1 of menu level 2.
Menu Level 2: Temperature Display
Line 1 indicates that you are on the Temperature Display screen.
Line 2 indicates the Temperature scale that you are currently in (Fahrenheit or Celsius).
Line 4 indicates the operation status of the machines Brew Valve(s).
To Change between temperature scales, press the button associated with line 2.
Use the ‘
▲ ’ ‘ ▼ ’ buttons to select the desired scale (Fahrenheit/Celsius), followed by the line 2 button
once again to confirm the selection. All temperature readings on the machine will now be in the se-
lected scale.
The Brew Valves can be set to the [ON] or [NORMAL] position in order to help with draining the brew
groups. Setting the Brew Valve function to the [ON] indicator will activate the brew valves, allowing
the pressure to be bled from the brew group(s). Once the pressure is bled, turn the Brew Valve setting
back to [NORMAL] and attach the appropriate drain hose to the brew groups drain tube. Set the Brew
Valve indicator back to [ON] once the drain hoses are securely attached. This will allow the water in
the brew group(s) to fully drain in approximately 5 minutes. When the brew groups are finished drain-
ing, set the Brew Valve indicator back to the [NORMAL] setting. If the draining process takes longer
than 5 minutes, the machines safety programming will automatically turn the brew Valve indicator to
the [NORMAL] setting while exiting back to the Display Default Overview screen. An error message
will also be sent to the Error Log that the brew valves have timed out. If more time is needed, return
to the Temperature Display screen and set the Brew Valve display back to the [ON] position to finish
the procedure.
To set the brew valves to [ON] or back to [NORMAL], press the button associated with line 4.
Use the ‘
▲ ’ ‘ ▼ ’ buttons to select the desired operation mode, followed by the line 4 button once again
to confirm the selection. Once finished with the draining procedures, make sure the Brew Valve indi-
cator is set back to the [NORMAL] position.
To cycle to the next display screen press the button to the left of line 1.
