1 Preparing and using for the first time
When setting up your GIGA, please note the following:
UPlace the GIGA on a horizontal surface that is not sensitive to
water (minimum height of 31.5 in. (80cm)).
UChoose a spot for your GIGA which protects the machine
against overheating. Ensure that the ventilation slats are not
covered.
Coffee beans which have been treated with additives (e.g. sugar),
ground coffee or freeze-dried coffee will damage the grinder.
T Only use roasted, untreated coffee beans to fill the bean
container.
TRemove the aroma preservation cover.
TRemove any dirt or foreign objects from inside the bean
container.
TFill the bean container with coffee beans and close the
aroma preservation cover.
When you use the machine for the first time, you must set the water
hardness. If you do not know the hardness of your water, you can
find this out first. Use the Aquadur® test strips supplied with the
machine.
THold the test strip briefly (for 1second) under flowing water.
Shake off the water.
TWait for about 1minute.
TYou will then be able to read the degree of water hardness
from the discoloration of the Aquadur® test strip and the
description on the packaging.

Your GIGA creates fine, creamy, feather-light milk foam with a
perfect consistency. The most important requirement for frothing
milk is a milk temperature of 39–46°F (4–8°C). We would therefore
recommend using a JURA milk cooler.
TConnect the milk pipe to the dual spout.To do this, attach
the end of the milk pipe to the connector on the right-hand
side of the dual spout.
TConnect the other end of the milk pipe to a milk cooler.
Your authorized JURA service technician can change various
settings, e.g.:
UCodes: Four codes can be assigned. For each code, you can
define which program items are available or disabled. Each
code corresponds to different authorizations. For instance,
you can define that initiation of the maintenance programs is
disabled using a code.

Hot coffee, hot steam and hot water can cause scalding. Scalding is
a serious burn.
T Use extreme care when handling hot liquid or steam.
T Allow liquid to cool down before drinking.
T In the event of scalding, rinse affected area with cold water
and seek medical attention.
T Keep children AWAY.
Basic information about preparing drinks:
UDuring the grinding operation you can change the coffee
strength of single products. To do this, move your finger
across the display or turn the Rotary Switch.
UDuring preparation you can change the preset amounts (e.g.
amount of water or milk foam). To do this, move your finger
across the display or turn the Rotary Switch.
UYou can stop preparation at any time. To do this, press the
‘Cancel’ button or the Rotary Switch.
UThe water volume is given as standard in ‘oz’. You can change
this setting to ‘ml’ in programming mode (see Chapter 4
‘Permanent settings in programming mode – Unit for amount
of water’).
Coffee tastes best served hot. A cold porcelain cup cools the
beverage – and impairs the taste. We therefore recommend
prewarming the cups. The full coffee aroma can develop only in
prewarmed cups. You can purchase a JURA cup warmer from your
specialized dealer.
You can make permanent settings for all products in programming
mode (see Chapter 4 ‘Permanent settings in programming mode –
Adjusting the product settings’).

2 Preparation
Your GIGA prepares latte macchiato, cappuccino, flat white and
other specialty coffees with milk at the touch of a button. There is
no need to move the glass or cup.
Example:Proceed as follows to prepare one latte macchiato.
Precondition:The start screen is displayed. Milk is connected to the
dual spout.
TPlace a glass under the dual spout.
TTouch ‘Latte macchiato’.
‘Latte macchiato’, the preset amounts of milk and milk foam
flow into the glass.
EThere is a short interval while the hot milk separates from the
milk foam. This allows the typical layers of a latte macchiato
to form.
Coffee preparation starts. The preset amount of water for
espresso flows into the glass. Preparation stops
automatically. Your GIGA is once more ready for use.
E15 minutes after preparation, the milk system is automatically
rinsed (see Chapter 5 ‘Maintenance – Automatic milk system
rinsing’). Therefore, always place a receptacle under the dual
spout after preparing milk.
To ensure that the milk system in the dual spout always works
properly, you must clean it daily (see Chapter 5 ‘Maintenance –
Cleaning the milk system’).
For the ‘Caffè Barista’ and ‘Americano’, the GIGA blends the coffee
with hot water using a special preparation method. This results in a
full-bodied specialty coffee which is particularly easy to digest. You
can change the amount of this additional water (see Chapter 4
‘Permanent settings in programming mode – Adjusting the
product settings’).
Products with a bypass amount of water setting are marked with a
red speedometer symbol in the start screen and in the product
selector.
EYour JURA service technician can set the machine so that the
red speedometer symbol is not displayed next to these ‘speed
specialty coffees’.
