3. Dispensing Steam.
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 the steam wand into the liquid to be
heated. Depress the steam valve lever to
activate the steaming process.
The steam valve has a variable ow control.
The steam valve will lock in the fully on
position only.
The steam will transfer heat to the liquid
raising its temperature. Be careful not to
allow liquid to overow in order to avoid
severe burns.
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.
NOTE: It is important to have a sufcient
volume of liquid in the steaming pitcher.
Therefore if you intend to steam small
amounts of milk it is necessary to use a
small pitcher. If you intend to steam larger
quantities of milk then it is necessary to
use a larger steaming pitcher.
Using too little milk in a steaming pitcher
can allow the milk to be “blown out” of the
pitcher. A good rule to follow is to ll the
steaming pitcher only half full of liquid.
NOTE: In order to prevent the heated liquid
from being sucked back into the steam
boiler it is recommended that you purge
the steam system after heating any liquid.
Purge the system by opening the steam
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 steaming pitcher to the steam boiler
(via vacuum created from cooling parts).
This condition is undesireable and can
cause contamination in the steam boiler.
4. Dispensing Hot Water.
You may dispense hot water by using the
hot water nozzle. To dispense hot water
press the hot water button.
This button commands the hot water
delivery. The volume of water delivered
may be adjusted via the display (see the
Software Programming Manual for further
instructions). The temperature of the water
dispensed may be adjusted by adjusting
the mixing valve under the right side cover
of the espresso machine (see machine
description diagram, Figure 2, and the
instructions on the next page).
