Introduction to Your AST A Espresso Machine

Congratulations on choosing ASTRA as your espresso machine!

Before we begin making espresso drinks, it is important to first

understand what espresso is. Espresso is a process in which you

extract the “flavor oils” from dark-roasted Arabic coffee beans.

Therefore, espresso is really the extraction process of the flavor

oils. That is what you are serving when you make an espresso.

When hot water hits the finely-ground, dark-roasted Arabic beans

at 135 PSI, the exposed oils will boil and turn to a reddish-gold

called “crema”. A properly-made espresso will not taste bitter or

burnt, but, instead, will exhibit a strong, sweet taste of coffee that

doesn’t attack the tongue. Rather, it has a smoothness that lets you

maximize the enjoyment of the blend of the roasted beans you

have chosen.

Read the ASTRA manual and follow the instructions closely, and

you will be enjoying espresso and cappuccino in minutes.

If you need any help or have any questions, please call your local

ASTRA representative.

B. equired Connections

1. Water:

All ASTRA machines (except the Gourmet series and Steamers) are

provided with a 1/4” male flare connection in the front, under the

drain tray (See Figure 1). The Gourmet series and Steamers are

provided with the 1/4” male flare connection underneath the

machine towards the right rear (See Figure 2).

A WATER PRESSURE REGULATOR IS SUGGESTED IF THE

WATER PRESSURE EXCEEDS 50 PSI.

2. Power:

All ASTRA machines must be connected according to the local and

national electrical and plumbing codes. For a 110 -Volt machine, a

separate circuit with ground is required. A 220-Volt machine must

be connected to a single phase power (2 hot and ground ) and the

equipment must be grounded.

3. Drain:

All ASTRA machines are provided with a flexible hose (1” outside

diameter) which must be connected to the drain basket under the

front drain tray (please see Figure 1) and must be sloped properly.

Please note that all AST A equipment must be installed in

accordance with all applicable Federal, State and/or local

electrical and plumbing codes.

C. Water Softener

It is highly recommended that the machine be used in conjunction

with a water softener in order to ensure the integrity of your

espresso drinks and to prolong the life of the individual

components of the machine.

The water softener must be periodically serviced (regenerated or

replaced) based on your usage. Please see the drawing (Page 24)

at the end of this manual for instructions for regeneration.

D. Grinders

CAUTION: Never put any fingers or any foreign objects into the

grinder without first unplugging it. Never put ground coffee into the

grinder, and please use ONLY whole beans.

The automatic and semi-automatic grinders are divided into three

main parts:

1. Hopper

2. Grinder Assembly

3. Doser (Dispenser)

1. Hopper

The hopper fits into the grinder collar and dispenses the beans into

the grinder. On the bottom of the hopper, there is a flap that can be

pushed closed to prevent beans from spilling out when removing

the hopper. Make sure the hopper is in the OPEN position when

the grinder is in use. On some grinders, the lid for the hopper has a

large safety magnet that extends down into the hopper. These

grinders will not work unless the lid is on.

2. Setting the Grind (Automatic & Semi-Automatic)

The On/Off switch is located on the lower left side of the grinder.

The automatic grinder should be left in the “On” position. It will

automatically turn off once there is a sufficient amount ground in

the dosing chamber. As you use the dispenser, the grinder will

automatically grind more to replace what has been used.

The semi-automatic grinder must be turned on and off manually in

order to keep ground coffee at the desired level in the dispenser.

Please ensure that you are operating the grinder with whole beans

only and that the hopper is in the OPEN position.

On the left side of the grinder collar, there is a spring-loaded,

push-lock pin. This locks the setting in place and prevents the

grinder from losing that setting. To adjust the grinder, depress the

push-lock pin with your finger. To obtain a finer grind, turn the collar

clockwise. To set the grinder for the first time, depress the lock-pin

and turn the collar clockwise until it stops. (Do NOT force the collar

to turn more.)

Once the collar is turned all the way down, note the number next to

the push-pin. Now depress the lock-pin and turn the collar back

(counter-clockwise) two turns, stopping when the same number is

next to the push-lock pin. This setting should be close to the

proper setting. You may adjust to finer or coarser grinds based on

the beans you are using.

3. Setting the Dosing (Automatic & Semi-Automatic)

Remove the lid from the doser and look at the bottom. Notice it is

divided like a pie where each section is an individual dose of

espresso. Also note that part of the pie is covered. The cover can

be raised/lowered to increase/decrease the amount of the dose. In

the middle of the doser there is an elevated stem which will raise

the cover when turned counter-clockwise and lower the cover

when turned clockwise.

Before setting the dose, make sure the dispenser is filled

one-quarter to one-half full. Put the portafilter in the yoke under the

dispenser and pull the lever once or twice until the coffee is

dispensed.

Make sure each pull is a full dose and then adjust the amount for

each dose. For a single dose, pull once, and for a double dose, pull

twice. A double dose should fill the double portafilter to about

one-eighth inch from the top and cover the lip in the middle of the

portafilter basket.

E. Automatic Espresso Machine

The following applies to ALL ASTRA Automatic Traditional

Espresso Machines Manufactured BEFORE anuary 1st, 2014

with GOLD color touch pad:

Open any steam valve and leave it open by turning the knob

counter-clockwise. Turn the machine on using the On/Off switch on

the front panel. All the computer lights will flash and then go off as

the machine undergoes a self-diagnostic test. Once the steam

begins to disperse from the steam wand, close the valve. When

broiler pressure on the gauge is in the green, you are ready to put

the machine into program mode. If you are using a two or three-

group machine, use the left/first touchpad while following the next

step of instructions. Push and hold the Brew/Stop button until all

the lights on that touchpad light up. If you have a two or three-

group machine, then push the Brew/Stop button for touchpad two

and three so all touchpad lights are on. Now the machine is ready

to be programmed.

Once you have programmed one pushbutton, the program is

automatically applied to ALL pushbuttons on the machine.

Take the single portafilter and put it in the yoke of the grinder. Pull

the lever once for a single dose and ensure the coffee is level. It is

NOT necessary to tamp the portafilter because ASTRA espresso

machines come with self-tamping group heads. To put the

portafilter on the group head, hold the handle level at 7 o’clock and

lift it up into the group head. Make sure the portafilter wings fit into

the slots and turn the handle to the right to create a tight seal.

CAUTION:Make sure that both of the portafilter wings are

securely aligned and that the portafilter has created a tight seal

with the group head gasket. If a tight seal is not created, a

potentially dangerous situation exists as hot water under pressure

could escape from the group head causing burn injuries. NEVER

remove a portafilter from the group head while it is under pressure

and brewing. Push the Brew/Stop button to stop brewing or wait

until the brew cycle stops.

Place an espresso cup under the portafilter. A single serving of

espresso is 1.5 to 2.0 ounces. Extraction time will be between 18 to

22 seconds. Push the first selection on the touchpad and

extraction will start. Once you have the right amount of espresso in

the cup, push the first selection again to stop the extraction. The

light for a single selection (on all touchpads) will start to blink. Once

the blinking stops and the light is off, the selection is now

programmed in all of the group heads.

Now use the double portafilter and complete the next selection

following the same steps. Repeat until all of the selections are

programmed. To exit the program mode, push and hold the

Brew/Stop button. All of the lights will come on and continue to

hold the button until the lights go out. Once the lights are out,

your selections are programmed and you have exited the

programming mode.

While the machine is extracting espresso, pump pressure gauge

will read approximately 135 PSI. On the front panel there are two

lights: green and amber. The green light indicates that the machine

is on while the amber light indicates when the heating element is

operating. The amber light will go on intermittently while the

machine is on regardless of whether it is in use or not.

Brew/Stop Button

The Brew/Stop button is a manual override for all selections. If you

should push the wrong selection, press the Brew/Stop button to

cancel that selection. If you need to extract an amount not

programmed, put the cup under the portafilter and push the

Brew/Stop button for extraction to begin. Once the desired level is

reached, push the Brew/Stop again to complete the extraction.

The Brew/Stop button can also be programmed as a fifth selection.

If you have programmed this button and now wish to return to

manual override, you must do the following:

1. Press and release the Brew/Stop button.

2. Quickly press and hold Brew/Stop button until the lights on

the keypad are on. (THE TIME DELAY BETWEEN STEPS 1

AND 2 MUST BE EXTREMELY SHORT.)

3. After a 10 second pause, press and hold the Brew/Stop

button until the lights on the keypad are off.

4. Now the Brew/Stop button is returned to the factory set

manual override.

F. Automatic Espresso Machine
