• When the machine is unattended for extended
periods, switch it off at the main switch and close the
water tap.
• Never open the covers unless explicitly instructed to
do so. Similarly, never remove bolts and the housing
parts that they hold in place. Contact with live parts
poses a danger of death due to electrical voltage.
• Never reach into a machine opening when the
machine is running.
• Do not hold any body parts under the outlets when
hot liquids or steam are being dispensed. This occurs
in the following situations:
After switching on,
when beverages are being dispensed,
during automatic cleaning,
during rinsing processes (e.g., when switching
• Do not touch any hot parts.
• When products are being dispensed, there is a risk of
scalding from the actual products. Always take care
when handling hot beverages.
• Take note of any visible damage or malfunctions.
Obvious malfunctions include water leaks, odors
and heat formation, unusual noises, as well as error
messages on the display. In the event of any unusual
situations:
Remove the mains plug

Installation
4 Installation
The machine is set up, installed and handed over ready
for use by the customer service. Due to the associated
hazards modifications to the installation or setup must
be carried out by the customer service only.
4.1 Prerequisites
Make sure that the following prerequisites are met
before you use the machine.
4.1.1 Water connection
The water connection must be easy to shut off at any
time during operation (shut-off valve). Any relevant
national regulations must be observed when connecting
this machine to the water supply, e.g., EN 61770.
The limit values for water pressure and carbonate
hardness as given in the technical data must be observed.
Only use a new hose set. Old or used hose sets are not
permitted to be re-connected.
The water drain must only be installed via a fixed connection with odor trap that is protected against backwater
and backflow.
This prevents contamination in the machine due to backflowing waste water.
4.1.3 Installation location
The machine is only to be installed and used in enclosed,
dry areas; it must not be operated outdoors.
The effects of humidity and temperature may adversely
affect the function and safety of the equipment.
The machine must always be installed and stored in frostfree locations.
The installation area must provide sufficient distances
from walls and objects due to the heat generated and for
operation of the machine.
Distances
To the back At least 5 cm
To the top At least 20 cm
In self-service operation, the machine and all accessory
units must be installed in such a way that they can be
permanently supervised by trained personnel.
The machine must be positioned level and free of vibrations. Adjustable feet are provided so that the unit can be
leveled out on slightly uneven surfaces.
4.1.4 Product material
Coffee beans must be suitable for use in commercial
coffee machines.
4
4.1.2 Electrical connection
The supply voltage must match the specifications on the
nameplate.
The supply line must be fuse-protected at the site with
3 x 16 A. The connection must also be protected using a
residual current circuit breaker (RCCB) (max. 30 mA).
If the equipment is connected permanently, a switch for
an all-pole disconnection with at least three millimeters
of contact clearance must be provided by the customer.
For connection via a mains plug, the socket must be
easily accessible during operation so that the plug can be
disconnected in the event of a fault.
Due to the high load, a separately fused circuit is required
for the machine.
Extraneous matter, such as pieces of wood, stones, or
metal, etc., must be removed to prevent damage to the
grinder.
Ground coffee or instant powder must be suitable for use
in commercial coffee machines. Only use dry and loose
material without clumps.
To ensure cold milk foam of the best possible quality, use
ultra-heat treated (UHT) milk cooled to a temperature of
3 °C (±2 °C).
Do not use milk that has not been treated in a dairy.
Lactose-free milk, milk from animals other than cows,
soya milk, alternative sources of protein, or additives can
be used; then, however, the cleaning of the milk system
cannot be ensured. The machine's owner/operator
is responsible for any breakdowns and work by the
customer service team.

Installation
4.2 Canister operation (option)
If your machine cannot be permanently connected to
the fresh water and waste water system, you can also
operate it with two canisters.
Also observe the limit values for the water carbonate
hardness in this process. Where necessary, the fresh
water supply must be topped up via the water filter (e.g.,
BRITA-Purity).
The canisters must always be installed by customer
service.
Note
Particular care with hygiene is required for
canister operation. Observe the relevant notes
4
in chapter 8.5 on page 29.
In daily operation, the fresh water canister must be filled
with sufficient water and the waste water canister must
be drained when necessary.
4.2.1 Filling the fresh water canister
1. Unfasten the quick-connect coupling of the supply
hose (1).
Move the ring backwards on the coupling piece.
Remove the plug connector from the coupling
piece.
2. Unscrew the lid from the canister.
3. Before filling, clean the fresh water canister and its
lid area with standard dishwashing detergent and
rinse off the cleaner residues thoroughly.
4. Fill the canister with fresh water.
Observe the limit values for the water carbonate
hardness. Where necessary, the fresh water supply must be topped up via the water filter (e.g.,
BRITA-Purity).
5. Screw the lid back onto the canister.
6. Connect the supply hose (1) to the canister.
Fit the plug connector onto the coupling piece.
Check that the plug connection is secure.
9 The fresh water canister is ready for operation.
4.2.2 Emptying the waste water canister
1. Remove the drain tube (2) from the canister lid.
2. Unscrew the lid from the canister.
3. Empty the canister.
4. Screw the lid back onto the canister.
