Safety
2�2 Safety information
2�2�1 General
The following safety information relate to
the machine only. In addition, there may be
legal requirements in place for the owner/
2
operator, e.g., regarding food hygiene and
safety at work.
• Only use the machine when you have read
and understood these instructions in full.
• When operating the machine, always
observe all information and guidelines in
these instructions.
• Keep these instructions at the place of
use of the machine.
2�2�2 Personnel
• This machine can be used by children
of 8 years and above as well as persons
with reduced physical, sensory, or mental
capabilities if supervised or when they
have been trained in the safe use of the
equipment.
• Children under 8 years of age must be
kept away from the machine.
• Children must not be permitted to play
with the equipment.
• Cleaning and user maintenance may only
be carried out by children if they are
properly supervised.
• Persons with limited experience and
knowledge must be able to recognize
hazards arising from incorrect operation.
• A user is only permitted to operate the
machine without supervision if it has
been explained in such a way so that the
user knows how to operate it safely.
• In self-service operation, the machine
must be supervised by trained personnel.
• Repairs and maintenance work may only
be carried out by Melitta customer service
or by specialist personnel authorized by
the manufacturer. Incorrectly performed
repair work can result in considerable risk
to the user.
• The area reserved specifically for customer
service is only to be accessed by persons
who have sufficient knowledge and
practical experience of the equipment,
particularly with regard to safety and
hygiene.
• Settings may only be made, and cleaning
and preparation work may only be carried
out on the machine by persons who have
been trained by the installation engineer
or by the manufacturer.
• Faulty components may only be replaced
with original spare parts. Otherwise the
warranty conditions will be void.
2�2�3 Correct use
• The machine can be damaged by pene-
trating water. The machine is not protected
against jets of water. Protect the machine
against water and spray water.
͵ Never pour water over the machine.
͵ Do not use any water jets, high-pres-
sure cleaners, or steam cleaners to
clean the machine.
͵ The machine is not suitable for instal-
lation on a surface where a water jet
might be used.
• 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 explic-
itly 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.
6
28514 • 20170301
Technical data
• 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 off)
• 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 mal-
functions. 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
situation:
͵ Disconnect the mains plug
͵ Switch off the water supply
͵ Contact customer service
͵ Have the machine checked and re-
paired by customer service
• Clean the machine at least once per day,
especially the parts in contact with milk.
Impurities could cause health problems.
• Comply with all intervals for cleaning,
inspection, and maintenance, as specified
in the instructions. Otherwise, the safety,
functional reliability, and durability may
be impaired.

Installation
4 Installation
The machine is set up, installed, and handed over ready
for use by customer service. Due to the associated
hazards, modifications to the installation or setup must
be carried out by 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
4
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�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 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 customer
service.

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 a water filter (e.g.,
BRITA-Purity).
The canisters must always be installed by customer
service.
Note
Particular care with regard to hygiene is
required for canister operation. Observe the
relevant notes in chapter 8.5 on page 31.
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 a 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.
