Brewing Espresso - Sirena SIN025RX Manual De Instrucciones

5 PULLING SHOTS
Warning! Do not remove the portafilter during coffee dispensing or immediately after brewing.
Wait 20 seconds while pressure is relieved in the filter: Danger of burning!
Warning! After pressing the coffee button(s), do not remove the portafilter immediately if
coffee does not flow out. In case this occurs, switch off the machine, and wait at 2-3 minutes
before removing the portafilter from the brew head.
The machine is fitted with a special pressurized portafilter (4), which allows you to pull either one or two
shots of espresso with the same filter basket for ground coffee (10).
• To brew espresso, the machine must be turned on with the ON/OFF button (15). Wait until the brew
lights (18 and 20) illuminate and remain fixed.
• During brewing, the machine ready lights located on the espresso buttons (18 and 20) may flash on and
off; this operation should be considered normal.
• Before use, make sure that the hot water/steam wand (6) is closed and the water tank contains enough
water.
• Do not remove water tank when unit is brewing.

5.1 Brewing Espresso

Using the Pressure Adapter (rubber gasket adapter and plastic support peg)
The Sirena is equipped with a special pressure adapter (11a) and plastic support peg (11b) that assist in
creating a full body espresso with crema, even if the grind is not perfect. This adapter and peg are to be
used when making single and double shots, and will help you make a great shot of espresso with a high
quality crema. The pressure adapter (11a) and plastic support peg (11b) are offered as replacement parts by
the manufacturer. To order new parts, please call 1-800-933-7876.
• Insert the plastic support peg (11b) into the portafilter (4). Then insert the rubber gasket adapter (11a),
with the curved side facing down, as shown in Figure M.
• Insert the ground coffee filter (10) into the portafilter (4). (Fig. N)
• Brew a single or double espresso as described in the sections below.
Note: When using pre-ground coffee, you must first insert the plastic support peg (11b) into
the portafilter, along with the rubber gasket adapter (11a), and then insert the ground coffee
filter (10), as shown in Figure N.
Note: The Sirena utilizes a self tamping method when brewing espresso: the coffee is tamped
when the portafilter is inserted into the brew head. For optimal brewing, it is better to avoid
tamping the coffee in the portafilter.

Brewing a Single Shot
For best results when making espresso, you will need to ensure the unit is fully warmed up and the
portafilter is preheated. A preheated portafilter will result in a higher temperature of coffee and will help retain
the espresso's flavourful taste. We suggest you dispense a couple of shots of water through the portafilter
to ensure it has been heated to the optimal temperature.
• Insert the plastic support peg (11b) into the portafilter body (4) along with the rubber gasket adapter
(11a). Then insert the ground coffee filter (10) into the portafilter (4) body. (Fig. N)
• Holding the handle towards the left, fit the rim of the empty portafilter into the brew unit (13), as shown in
Figure P.
• Turn the portafilter from left to right until it firmly locks in place; you may have to hold the base of the
machine to keep it from turning.
• Release the grip from the portafilter.
• Preheat the portafilter by pressing the brew button (17). Place a cup beneath the portafilter. Water will
dispense out of the portafilter (this operation is only necessary for the first espresso during each use).
• Caution! The water will be very hot!
• To pull one shot, insert 7 grams or one scoop of espresso in the ground coffee filter basket (10). This will
correspond to approximately 1/2 full portafilter. (Fig. O)
• Clean any espresso residues from the edge of the portafilter.
• Insert the portafilter into the brew unit (13) from the bottom, and turn the portafilter from left to right until it
locks into place. (Fig. P)
• Take one preheated cup and place it under the portafilter; check that it is correctly placed under the
dispensing holes.
• Press and release the single espresso button (17). The button light (18) will blink quickly when preparing
to brew the espresso.
• The machine will dispense a single shot (1 fluid ounce) of espresso.
Brewing a Double Shot
• Preheat the portafilter, as described above in "Brewing a Single Shot".
• To pull a double shot, insert approximately 14 grams or two scoops of espresso in the ground coffee filter
basket (10). This will correspond to approximately 3/4 full portafilter. (Fig. O)
• Clean any espresso residues from the edge of the portafilter.
• Insert the portafilter into the brew unit (13) from the bottom, and turn the portafilter from left to right until it
locks into place. (Fig. P)
• Take one or two preheated cups and place them under the portafilter; check that they are correctly
placed under the dispensing holes.
• Press and release the double espresso button (19). The button light (20) will blink quickly when preparing
to brew the espresso.
• The machine will dispense a double shot (2 fluid ounces) of espresso.
The espresso quantities can be programmed according to your personal tastes (see section 5.3).
• When the programmed quantity of espresso has been reached, the brewing stops automatically.
• Remove the cup(s).
• Wait a few seconds, then remove the portafilter and empty it from remaining espresso grounds.
Note: Keep the ground coffee filter basket (10) clean by removing and rinsing it every time
with water (see section 9). For deep cleaning, remove the filter basket (10), rubber gasket
