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 (Fig. A-2) inside the liquid in the
recipient just below the surface of the liquid. To avoid personal injury always
ensure that the end nozzle of the steam pipe (Fig. A-2) is below the surface of
the liquid to be steamed.
3. Turn on steam valve (Fig. A-1).
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. A-1).
Clean the steam wand (Fig. 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
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 (fig. A-2) into the centre milk just below the surface of the
milk.
3. Open steam valve (fig. A-1) rapidly.
4. Steam will come out of the nozzle and froth the milk. The milk volume will
increase rapidly. Please lower 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. A-1) rapidly, then remove milk pitcher from steam wand.
7. Wipe the steam wand (Fig. A-2) immediately after using with a non abrasive
clean damp towel without touching the steam wand (Fig. 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 (Fig. A-2) immediately after using opening and closing
immediately after the steam valve (Fig. A-1). Caution: Hot steam will come
out of steam wand (Fig. 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 (Fig. A-11) inside a suitable
pitcher used for food only.
2. Open the hot water valve (Fig. A-12).
3, Hot water will be dispensed into the pitcher.
4. Close the hot water valve (Fig. A-12) when you’re done.
