with a non abrasive clean damp cloth after each single use without touching

it directly with any part of the body to avoid injury or damage due to the hot

surface of steam wand end nozzle. Caution: Hot surface.

Example: Steaming milk

1. Use a clean, cold pitcher and fill 1/3 with cold, fresh milk.

If milk has previously been steamed and stored in the refrigerator, we

suggest adding some fresh milk in order to achieve optimum foam. Milk

should be stored at a temperature around 4-5°C (app. 40°F).

2. Insert steam wand’s (Fig. 1-4) nozzle into the centre milk just below the

surface of the milk.

3. Open steam valve (Fig. 1-2) rapidly.

4. Steam will come out of the nozzle and froth the milk. The milk volume will

increase rapidly. Please lift the pitcher progressively to make sure that

the steam nozzle is always right below the surface of the milk.

5. When enough foam is achieved, submerge nozzle (going sidewise) and keep

it in that position finishing heating milk until the pitcher is too warm to

touch.

Please remember that milk should never be steamed over app. 76°C

(168°F). Milk steamed to over this temperature is scalded.

6. Close steam valve (Fig. 1-2) rapidly, then remove milk pitcher from steam

wand.

7. Wipe the steam wand (Fig. 1-4) immediately after using with a non

abrasive clean damp towel without touching the steam wand (Fig. 1-4)

directly with any part of the body to avoid injury or damage due to the

hot surface of steam wand and end nozzle. Use a towel that is

designated for the steam wand only. Do not cross contaminate

kitchen towels by using the same towel for cleaning the steam wand

and i.e. kitchen tops.

Do not let the milk bake onto the steam wand. Clogged wands and steam

valves can be expensive to repair or to replace.

_____________________________________________________________________________________________

8. Burp your steam wand (Fig. 1-4) immediately after using opening and

closing immediately after the steam valve (Fig. 1-2). Caution: Hot steam will

come out of steam wand (Fig. 1-4).

9. Finish espresso drinks with correct portions of milk and foam.

10. Clean steam pitcher and store for next drink.

Switching off the machine

Turn the main switch (Fig.1-10) to position 0.

The machine must be disconnected from the mains (switch off external main switch)

whenever it is left unattended. The connection to the water mains must be closed.

Proper care and maintenance

Simple, routine care of your espresso machine is your best defence against poor

quality shots, as well as preventing breakdowns or, even worse, personal injuries.

After each use:

 Wipe the steam wand (Fig. 1-4) immediately after using with a non abrasive

clean damp towel without touching it directly with any part of the body to avoid

injury or damage due to the hot surface of steam wand end nozzle.

 Do not let the milk bake onto the steam wand.

 Clogged wands and steam valves can be expensive to repair or to replace.

 Burp your steam wand (Fig. 1-4) immediately after using opening and closing

immediately after the steam valve (Fig. 1-2).

Caution: Hot steam will come out of steam wand (Fig. 1-4).

Burping the wand will remove the milk residue from the inside of the nozzle.

 Knock used coffee grounds from filter holder and rinse. Re-use or store in

brewing head (group) to keep the filter holder warm. (Please remember to take

out filter holders when machine is not operating for some hours (i.e. at night).

Throughout the day:

Wipe the screens inside your group head with a damp clean towel to remove excess

grounds. Do not touch metal parts. They can be come hot. Caution!

_____________________________________________________________________________________________

Before shutting down the machine (i.e. at night):

For the following operations the machine has to be switched on:

Rinsing the brewing head (“group”) – Fig. 1-6. With a small hard clean brush, give

the inside of the group a good scrub.

The group should be back flushed regularly. This means after each day, firstly,

remove the filter basket and then fit the blind filter into the handle.

Next fit the handle into the espresso machine.

NOTE: This filter basket has no holes so the water pressure will build up and the

water is very hot. Caution!

Press key (Fig. 3-1) and switch it off after 15 seconds.

The purpose of this is to push fresh brewing water back through the coffee brewing

head (group) and back out through the exhaust solenoid valve thus cleaning the

coffee brewing group of the machine.

Repeat this procedure several times, and each time you turn off switch Fig. 3-1

remove the filter holder and empty the water sitting in the blind filter. Repeat until the

discarded water is clean and fresh.

Next or weekly, put a small amount of special detergent for espresso machines into

the blind filter and repeat the process as above. Repeat this process until the

detergent runs clean into the drain tray via the exhaust solenoid.

Ensure that you back flush the machine once again so the detergent residues are

washed away.

For the following operations the machine has to be switched off, unplugged

and completely cooled down:

Clean showers, group gaskets and group flange with a clean brush (to be used only

for this purpose).

Cleaning the filter holder and the metal filter baskets:

With a small screw driver or teaspoon, flick out the filter basket from the handle.

Once you have the filter basket out, clean both the filter basket and the internal

surface of the handle with a pot scourer until both surfaces are clean from the black

coffee oils.

Should the oils in the handle have built up to excessive amounts, it may be necessary

to soak the handle and the metal filter basket in hot water with a cap full of special

detergent product for espresso machines for 30 minutes or so and then rinse

thoroughly in fresh water.

Wash metal filter baskets and filter handle in warm water adding a special detergent

product or espresso machines following the instruction’s of the specific product. It has

to be food quality and for this specific use with coffee machines.

_____________________________________________________________________________________________

Clean the drip tray (Fig. 1-7) and grid with a non abrasive clean damp cloth.

Clean drain tray (located under the drip tray) with a clean damp cloth and a clean

brush.

Wipe down surface of machine with non-abrasive clean cloth. Do never use aggressive

cleaners or scouring powders! This operation has to be done when necessary.

How to disassemble/dismantle the machine

The machine has to be disassembled and dismantled by an authorized technician

according to local law and jurisdiction.

The machine must be switched off, disconnected from mains and water supply and

cooled down.

1. Clean filter holders, baskets and brewing head (“group”).

2. Switch off and let machine cool down to ambient temperature.

3. Remove the drip tray (Fig. 1-7)

4. Open the boiler drain valve (located under the drip tray). The boiler water will
