Once the air valve is adjusted, dispense two of a hot drink and iced drink and
observe any spitting from the spout in the beginning and end of dispensing.
NOTE: If spitting is still observed, slightly close the screw (turning clockwise)
until there is no spitting and re-run drinks. If there is residual coff ee remaining
in the brewing lines, slightly open the screw until dispensing runs smoothly.
Once complete, use the short Schaerer tool to screw the panels back on.
