On the JURA website (www.jura.com) you will find interesting and
up-to-date information on your GIGA and on every aspect of coffee.
A few preparations are necessary before the JURA service technician
can set up your GIGA in your home. The following preparations must
be carried out by a professionally qualified person:
UThe mains connection for the GIGA must be protected by a
residual current device (RCD).
UThere must be a power switch to disconnect the power supply
to the GIGA.
UThe permanent water connection must have a shut-off valve
with a non-return valve (type EA) and filter.
UThe permanent water connection must comply with the spec-
ified technical data (see Chapter 9 ‘Technical data’).
UThe drain hose must be connected to a siphon.
EThese preparations must be carried out by a qualified person.
EThe preparations must be carried out before the JURA service
technician sets up your GIGA in your home.
When setting up your GIGA, please note the following:
UPlace the GIGA on a horizontal surface that is not sensitive to
water.
UChoose a spot for your GIGA which protects the machine
against overheating. Ensure that the ventilation slats are not
covered.
The bean containers have an aroma preservation cover. This will
ensure that your coffee beans retain their aroma for longer.
Coffee beans which have been treated with additives (e.g. sugar),
ground coffee or freeze-dried coffee will damage the grinders.
T Only use untreated coffee beans to fill the bean containers.
TRemove the aroma preservation cover.
TRemove any dirt or foreign objects from inside the bean
container.

USet for automatic discharging of coffee grounds
You can find out what the water hardness is by using the Aquadur®
test strip supplied as standard.
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 discolouration of the Aquadur® test strip and the
description on the packaging.
Your GIGA creates fine, creamy, feather-light milk foam with a per-
fect consistency. The most important requirement for frothing milk
is a milk temperature of 4–8°C. We would therefore recommend
using a milk cooler (e.g. the JURA Compressor Cooler Pro, which is
available as an option).
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.

EWhile a product is being prepared, you can stop preparation
at any time. To do this, press the Rotary Switch kor the
‘’button.
EDuring preparation, you can change the preset amounts
(e.g. amount of milk foam or water) by turning the Rotary
Switch g. For products with a set bypass amount of water, it
is not possible to change the fill volume during the prepara-
tion process.
EYou can follow the current status of preparation on the display.
Coffee tastes best served hot. A cold porcelain cup cools the bever-
age – 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 specialised dealer.
You can make permanent settings for all products in programming
mode (see Chapter 4 ‘Permanent settings in programming mode –
Product settings’).
The GIGA provides you with two options for preparing a speciality
coffee, milk or hot water.
UPreparation at the touch of a button: Simply press the cor-
responding preparation button for the product shown on the
display (start screen) that you want.
UPreparation using the product selector (Rotary Selection):
Only some of the products you can prepare are shown on the
start screen. As soon as you turn the Rotary Switch, more
products are displayed in a product selector.
