Instruction Supplement for Rocket Espresso model ranges
Evoluzione & Professionale
The Rocket Espresso Evoluzione and Professionale ranges are built with full commercial rotary pumps. This
feature enables the user to connect the machine directly to the mains water supply.
In the case of the Evoluzione range, there is the choice to use the 2.9 Litre water reservoir or alternatively use a
mains water connection. The Evoluzione model range is preset at the factory to use the supplied 2.9 Litre water
reservoir. To set the Evoluzione machine to be mains water fed, please ensure the following instructions are
adhered to:
Using the steel braided water hose supplied, connect the machine to the main water supply. Rocket Espresso
recommends the following procedures when installing the machine to a mains water supply feed;
• Rocket Espresso recommends using a certified plumber to complete the installation and insure that the
installation meets local authority standards and regulations in all cases. Line pressures exceeding 5 bars
should be limited with the use of a pressure regulating valve on the water feed line.
• Rocket Espresso recommends the use of a shut off valve to isolate the water supply to the machine.
• If you are drawing the water from a non pressurised system (ie from a remote water supply tank, not mains
pressurised) it is recommended that a non return valve is fitted to the end of the water supply hose to ensure
that line pressure is maintained at all times.
• Rocket Espresso recommends the use of an inline filter to ensure the water supply to the machine is of the
highest quality. (Example; everpure ocs filter range).

Dispensing steam to froth or heat up liquids
1. Fill a suitable ideally stainless steel pitcher (used for food only) with an insulated grip with the liquid to be heated
up or frothed.
2. Position the steam nozzle of the steam wand (A-2) just below the surface of the liquid inside the liquid in the
recipient. To avoid personal injury always ensure that the end nozzle of the steam pipe (A-2) is below the surface
of the liquid to be steamed.
3. Turn on steam valve (A-1) fully.
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 (A-1).
Clean the steam wand (A-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. For the correct milk texturing and heating technique see page 28.
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 nozzle (A-2) into the centre milk just below the surface of the milk.
3. Open steam valve (A-1) 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.

20
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 (A-1) rapidly, then remove milk pitcher from steam wand.
7. Wipe the steam wand (A-2) immediately after using with a non abrasive clean damp towel without touching the
steam wand (A-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 (A-2) immediately after using opening and closing immediately after the steam valve (A-1).
Caution: Hot steam will come out of steam wand (A-2).
Burping the wand will remove the milk residue from the inside of the nozzle.
9. Finish espresso drinks with correct portions of milk and foam.
10. Clean steam pitcher and store for next drink.
Dispensing of hot water
1. Position the end nozzle of the hot water wand (A-11) inside a suitable pitcher used for food only.
2. Open the hot water valve (A-12).
3, Hot water will be dispensed into the pitcher.
4. Close the hot water valve (A-12) when you’re done.
