‣
To decrease the flow rate, turn the blue control knob on the needle valve
clockwise.
‣
To increase the flow rate, turn the blue control knob on the needle valve
counter-clockwise.
9. Repeat all steps for each grouphead.
IMPORTANT: Over-tightening the valve may break the needle inside. Only adjust
the flow rate incrementally to avoid damage.
Adjust Brew Tank Temperature
At the Slayer studio, brew tanks are set to 93ºC (200ºF). Each grouphead has its
own PID temperature controller, which can be manipulated independently. Adjust
the brew tanks’ temperatures with the following steps.
1. Begin with one grouphead:
briefly press the
corresponding PID controller’s
green "SEL" button, which will
engage the red "SV" light.
‣
The “C2”, “AL1”, and “AL2”
indicators are not used on
Slayer.
2. Use the up and down arrow
buttons to select the desired
temperature.
3. Press "SEL" again to return to
normal operation, indicated by
the red "SV" light turning off.
‣
The new temperature will be achieved and stable within 10 minutes.
4. Repeat all steps for each grouphead.
NOTE: Each of the brew tanks’ PIDs has an "F" printed on its plastic exterior,
which indicates temperature readings in degrees Fahrenheit. However, the actual
temperature may read in either Fahrenheit or Celsius, depending on your
request at the time of ordering.
Adjust Brew Pump Pressure
At the Slayer studio, the brew pump pressure is set at 9 bar. Actual brew pressure,
as indicated by the pressure gauge on the face of your machine, will be influenced
by incoming water pressure (line pressure) at your location. Adjust the brew pump
pressure with the following steps.
1. Lock a loaded portafilter, blind insert, or Scace device in the grouphead, then
move the brew actuator to the “full brew” position.
