Priming The Water Circuit; Drip Tray Adjustment - STARBUCKS Sirena User Manual

4.5 Priming the water circuit

The machine's water circuit must be primed in the following cases: before using the machine, for the first time
out of the box, or after long periods of inactivity, and when the water tank becomes empty.
The machine indicates the need to prime the water circuit when the water light is blinking (24).
• Press the main power button (15). The button lights will start blinking slowly. This means the machine
is warming up. The blinking will stop when the machine is warmed up and ready to use.
• Place a container below the steam wand. Open the hot water/steam wand by turning the knob (6) clockwise
all the way.
• Wait until the water light (24) stops blinking.
• Close the hot water/steam wand, by rotating the knob (6) counter-clockwise all the way.
• The machine has been primed when the water light (24) shuts off.
• Remove and empty the container.
The machine will give best performance if the unit is allowed to fully heat up prior to pulling a shot of espresso.
For best results when making espresso, you will need to preheat the portafilter. A preheated portafilter will
result in warmer coffee and will help retain the espresso's flavourful taste.
• Insert the portafilter into the machine without coffee, and place a cup beneath the portafilter. (Fig. H)
• Press the coffee button (17). Allow the machine to dispense water through the portafilter.
• We suggest you dispense a couple of shots of water through the portafilter to heat it up to the optimal
temperature.
• When not brewing a cup of espresso, leave the cleaned portafilter attached to the machine. This will
ensure the portafilter remains preheated.
The machine is now ready to dispense espresso and steam; please see related sections for operating details.
NOTE: The temperature gauge is a general indicator of the machine temperature. When the machine
is warming up, the coffee lights (18 and 20) will blink. The machine is warmed up and ready to use
when the coffee lights remain fixed. Even if the temperature gauge is in the green area, the machine
is ready to use only when the coffee lights remain fixed.

4.6 Drip tray adjustment

The drip tray can be adjusted according to the size of the cup(s) used.
When using small espresso cups or shot glasses used to prepare espresso, we recommend raising the drip
tray to the higher position, for optimal crema (Fig. G). If larger cappuccino or latte cups are used, lower the
drip tray. (Fig. H)
To lift the drip tray height, proceed as follows:
• Remove the drip tray grill and the drip tray. (Fig. I)
• Turn the "X" support upside down so that the hinges match up with the reference marks inside the base
of the machine as shown in the figure. (Fig. J and Fig. K)
• Place the drip tray and the grill back into place. (Fig. L)
