Dispensing Steam And Hot Water - La Marzocco strada ep Operating Manual

5. Dispensing Steam and Hot Water

1) Steaming milk or other liquids
In order to allow for any condensed
water in the wand to be released ALWAYS
allow some steam to be discharged by
turning on the valve before inserting the
steam wand into the pitcher of liquid to
be heated.
Dip one of the 2 steam wands (item 10,
page 5) which are connected to the steam
valve, into the liquid to be heated. Move
the steam wand lever gradually until
steam comes out at the end of the wand.
The steam will transfer heat to the liquid
raising its temperature up to boiling
point.
Be careful not to allow liquid to overflow
in order to avoid severe burns.
In order to prevent the heated liquid
from being sucked back into the steam
boiler it is recommended before using
the wand that you purge the steam valve
and steam wand by opening the valve for
a few seconds to allow steam to escape
to the atmosphere from the end of the
steam wand. Failure to do so can cause
the heated liquid to transfer from the
18
heated liquid container to the steam
boiler (via vacuum created from cooling
parts). This condition is undesireable and
can cause contamination in the steam
boiler. After use remember to purge the
wand by opening the steam valve for a
few seconds, and then clean the outside
of the wand itself with an appropriate
cloth.
In order to prepare milk for making
cappuccino with the right amount of
foam, go through the following steps:
• After purging the steam wand place the
container half-full of milk underneath,
carefully open the steam valve and raise
the container so as to bring the wand end
to a point just below the surface of the
milk; at this point, move the container
up and down just enough to dip the
nozzle end in and out of the milk until
you get the right amount of foam, bring
the temperature of the milk almost up
to 149/158°F or 65/70°C. You can then
pour this milk into a cup containing warm
espresso and you will end up with a fresh
cup of cappuccino.
2) Preparing tea and other hot drinks
You may dispense hot water by using the
fixed nozzle (item 5 page 5). To dispense
hot water, press the tea water button.
This button commands the hot water
delivery.
The temperature of the water may be
adjusted by adjusting the mixing valve.
