steamed.

3. Turn on steam valve (Fig. 1 or Fig. 1B – Pos. 3).

4. Heat up or froth the liquid inside the pitcher. Pay attention to hot sprays!

They may cause injuries.

5. When you’re done, close the steam valve (Fig. 1 or 1B - 3).

6. Clean the steam wand (Fig. 1 or 1B - 2) and the steam wand’s end nozzle

carefully with a non abrasive 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 or 1B - 2) nozzle into the centre milk just below

the surface of the milk.

3. Open steam valve (Fig. 1 or 1B - 3) 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 or 1B - 3) rapidly, then remove milk pitcher from

steam wand.

7. Wipe the steam wand (Fig. 1 or 1B - 2) immediately after using with a non

abrasive clean damp towel without touching the steam wand (Fig. 1 or

Fig. 1B – Pos. 2) directly with any part of the body to avoid injury or

damage due to the hot surface of steam wand 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 or Fig. 1B – Pos. 2) immediately after using

opening and closing immediately after the steam valve (Fig. 1 or Fig. 1B –

Pos. 3). Caution: Hot steam will come out of steam wand (Fig. 1or Fig.

1B – Pos. 2).

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

10. Clean steam pitcher and store for next drink.

Turning off the machine

Turn the main switch (Fig.1-1 or 1B - 1) 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 or Fig. 1B – Pos. 2) 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 or Fig. 1B – Pos. 2) immediately after using

opening and closing immediately after the steam valve (Fig. 1 or Fig. 1B –

Pos. 3).

Caution: Hot steam will come out of steam wand (Fig. 1 or Fig. 1B – Pos. 2).

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. Caution: hot metal surfaces!

_____________________________________________________________________________________________

Before shutting down the machine after work:

For the following operations the machine has to be on:

Scrubbing the inner side of the brewing head (where the filter holder is tightened in):

With a small hard brush, give the inside of the group a good scrub. Caution: hot metal

parts! Do not touch! When done depress with RE A series machines key Fig. 2-A (“P”)

and with RE S series machines key Fig. 1B to dispense some hot water. Depress these

keys again after five seconds to stop water dispensing.

Back flushing (“rinsing”) of the group: The group should be back flushed at least once

a day (typically after work) with a specific food quality cleaning product for espresso

coffee machines. This operation is done individually with every group. Start

proceeding as follows:

Replace the filter basket inside the filter holder with the blind filter basket (the one

without holes). Now put the specific food quality cleaning product for espresso coffee

machines into the blind filter basket (quantity of cleaning product according to

manufacturer’s instructions; typically half a coffee spoon of product)). Now tighten the

filter holder into the group. From now on please follow the dedicated procedures for

RE A and RE S machines.

With RE A machines (automatic portion control) please use the built-in

semiautomatic back flushing program: Select the group you wish to back flush. Now,

operating with the selected group, keep key Fig. 2-A depressed while depressing key

Fig. 2-B. The leds of both keys start flashing. When the back flushing cycle is finished,

these keys stop flashing. Remove the filter holder from the group and depress key Fig.

2-A again. Dispense hot water for another 10/15 seconds and depress this key again

to stop. The operation for this group is done. Please note that while the back flushing

program is running on one group, you can operate with the other ones.

With RE S machines please proceed as follows: Depress key Fig. 1B – 5 and switch

it off after 15 seconds. Repeat this procedure about 5 times. When done remove the

filter holder, depress key B1-5 and dispense hot water for about 15 seconds. The

depress key B1-5 again to stop dispensing.

After backflushing the water being dispensed should be clean and fresh.

If needed, please repeat the back flushing again with water only to make sure 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 dark

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.
