5.OPERATING INSTRUCTIONS
Cup heating tray
The Nivola features a cup warming
tray for up to six cups.
Under normal use, the machine
would be left on during the day,
allowing the cup warming surface
to reach a suitable temperature.
Place cups upside down on the
tray, as shown.
Operating principle
When the coffee function is
selected, if the boiler water is at
the correct temperature, an elec-
tric pump inside the machine is
switched on, pumping water from
the reservoir into the bottom of
the boiler.
The pump operates at a high
pressure, so when cold water is
pumped into the boiler, the boiler
pressure rises. This causes the hot
water at the top of the boiler to
flow through the coffee grounds in
the filter basket, into the cup.
When the steam function is select-
ed, the boiler water temperature
needs to be high enough to pro-
duce steam, sometimes causing
the red stand-by light to come on
while the boiler temperature rises.
The steam is directed to the steam
wand with an electrically powered
solenoid valve that is operated
when the steam function is
selected, but only when the boiler
temperature is high enough to
produce steam. After using the
steam wand, the boiler is refilled
automatically by the pump, which
will come on briefly when the
control knob is returned to the
off position.

The main requirements for making

cups,
coffee handle and

Procedure
Ensure machine is warmed up
,
in particular the coffee handle
and filter basket. This can be
done by placing the handle
(fitted with a filter basket) into
the machine, selecting the
coffee
function and allowing
hot water to flow through the
handle for five seconds or so.
This procedure will also help
warm up the machine by
causing the boiler’s heating
element to operate.

To make a single cup
— fit the
single cup filter basket to the
handle, add one
heaped
espresso dosing spoon of cof-
fee grounds to the basket, and
tamp down firmly.
The tamped grounds should
be approximately 4mm from
the top of the basket.
To make a double cup
— fit the
double cup filter basket to the
handle, add one
level
espres-
so dosing spoon of coffee
grounds to the filter basket
and tamp down firmly. Add
another level dosing spoon of
coffee grounds and tamp
firmly. The tamped grounds
should be around 4mm from
the top of the basket, as below.
Wipe the top of the basket to
remove any coffee grounds.
This is important, as the rim of
the filter basket forms a seal
with a rubber ring inside the
group head. Coffee grounds
can prevent a good seal and
will build up inside the group
head, possibly causing the
rubber sealing ring to be
released from inside the group
head.

Fit the coffee handle into the
group head, then pull the han-
dle horizontally to the right.
As the rubber ring settles in
with use, the handle will need
to be moved further. The aim is
to obtain a sufficiently tight
seal (but not too tight) so there
are no leaks while coffee is
being extracted.
Place coffee cup(s) onto drip tray.
Turn the control knob to the
coffee
position (right) to extract
coffee to the desired level.

Note
: If the stand-by light comes on, wait
until it’s extinguished, when the machine will
start automatically.
When the required coffee level
is reached, turn the control
knob to the
off
(centre)
position to stop coffee flow.
Remove the handle by slowly
and carefully pulling it horizon-
tally to the left.
Dump the used coffee cake.
Rinse the handle (and filter-
basket),
and replace
handle/basket in machine to
keep it warm.

7.FROTHING OR HEATING MILK
Immerse steam wand into milk
ensuring the small breather
hole on the top of the wand
is not covered.
Turn the control knob to the
steam function. (The stand-by
light will come on to allow the
boiler to reach the correct
operating temperature and
pressure. As soon as it goes
out, steaming will start
automatically.)

The Nivola will
not
allow you to
extract coffee and use the steam
wand together. Therefore froth or
heat milk
before
extracting coffee.
Purge the steam wand of
condensation by releasing
steam into a container.
Fill a stainless steel jug with
the required amount of milk.
