These safety instructions refer only to the machine
itself. Apart from that there myay be legal obligations
of the operator, e.g. concerning food hygiene as well
as health and safety.
mIn the beverage dispensing area there is danger
of scalding when hot liquids are dispensed. This
is the case …
mduring heating up after switching on,
 when beverages are being dispensed,
 during automatic cleaning,
 during the flushing process after switching off.
mDanger of crushing if somebody reaches into
the provision container while the machine is op-
erational.
mThere may be danger to life caused by electri-
cal shock as well as risk of injury due to hot or
moving parts when housing parts or covers are
opened.
 Make sure that no person reaches into the ma-
chine while it is still switched on.
 Never open any housing parts or covers unless
instructed to do so. There are no operator ele-
ments inside the machine.
mProtect the machine from humidity! There
may be danger to life through electrical shock if
water reaches machine parts other than those
specifically intended for contact with water. You
should …
 never operate the machine outdoors,
 never hose down the machine with water,
 never hose down the installation area with wa-
ter, e.g. using a hose or high-pressure cleaner.
mDo not continue using the machine if damage
is visible or apparent malfunction occurs. Im-
portant safety functions may be disturbed in this
case. It is recommended that the coffee machine
is first inspected and, if necessary, repaired by
the customer service. Examples are:
 if the housing is damaged or covers do not
close properly,
 if the power cord or power plug are damaged
or if the fuse for the circuit of the machine trips
repeatedly,
 if water escapes from the machine,
 if error messages appear on the display or if the
machine does not function normally,
 if unusual odours can be detected or heat de-
velopment on the housing is apparent (the hous-
ing is normally only warm to the touch during op-
eration).
 In all of these cases, remove the plug from the
power socket and turn off the water. Then notify
customer service.
mComply with all intervals for cleaning, inspec-
tion and maintenance, as specified in the instruc-
tion manual. Otherwise, the safety, functional re-
liability and durability may be impaired.

5
6. Installation
Customer service will install and commission the
coffee machine ready for operation. Due to the
associated hazards, changes to the installation or
setup of the coffee machine should only be complet-
ed by customer service.
6.1 Prerequisites
Make sure that the following prerequisites are met
before you use the machine:
a) Prerequisites for water connection
The water connection must be easy to turn off at any
time during operation (stop valve) and must meet the
requirements of EN 61770.
As specified in the technical data, the values for wa-
ter pressure and carbonate hardness must compy.
The water supply must generally be equipped with a
fine filter.
Only use the new hose kit! Old, previously used
hose sets must not be connected.
The waste water drain must be installed as a fixed
connection with odour trap, protected against back-
water and backflow, in order to protect the machine
against contamination from back flowing waste water.
b) Prerequisites for electrical connection
The supply voltage must match the specifications
on the type plate.
The supply line must be fuse-protected by the cus-
tomer using a fault current circuit breaker (FCCB)
(max. 30 mA).
When connected via a power plug, the outlet must
be easily accessible during operation to be able to
disconnect the plug in case of malfunction. Due to
the high load, a single socket is required for the
machine and each accessory.
c) Requirements on the personnel
Adjustments, cleaning and preparations on the
machine must only be performed by the installer or
by persons instructed by customer service..
Any repair and maintenance work must only be
performed by customer service or by professional
personnel authorized by the manufacturer.
The machine must only be operated (in the self-
service or waiter operation) by persons familiar
with the general use of heat-generating appliances in
the catering industry. Without supervision or appro-
priate instructions the machine must not be used by
children or persons unable to safely use the unit be-
cause of their physical, sensory or mental abilities or
their lack of experience or subject knowledge.
d) Requirements on the installation location
The machine must only be installed and used in
closed dry rooms, it must not be operated outdoors!
The effects of humidity and temperature may ad-
versely affect the function and safety of the machine.
The machine may only be installed or stored at loca-
tions safe from freezing.
The installation area must offer a sufficient amount of
free space – 10 cm at the back because of the heat
development, 20 cm at the top to be able to fill the
machine. For self-service operation the machine
must be installed in such a way, that it can be per-
manently monitored by instructed personnel.
The machine must be in horizontal position and free
of vibration. Adjustable bases are available for
alignment on slightly uneven surfaces
e) Requirements on the product material
Coffee beans must be suitable for use in commercial
coffee machines. Extraneous matter such as pieces
of wood, stones or metal, etc should be removed to
prevent damage to the grinding burrs.
Coffee powder or instant powder must be suitable
for use in automatic coffee machines. Only use dry
and loose, but no clumped material.
Use ultra heat treated milk (UHT milk) cooled
down to approx. 4°C for the best possible quality
cold milk foam.
6.2 Canister operation
If your machine is not permanently connected to the
fresh and waste water system, you can also operate
it with 2 canisters. In this case also observe the
limiting values for the water carbonate hardness.
The freshwater canister may need to be filled through
the water filter (Brita).

Plug the quick release coupling from ...
(1) the supply hose onto the connection on the
fresh water canister,
(2) the drain hose onto the connection on the waste
water canister.
Always keep the connections clean and free of
burrs to prevent the seal ring on the coupling
from being damaged.
You can loosen these connections again by
simply sliding the ring on the quick-plug cou-
pling back.
Caution: Canister operation requires the highest
attention with regard to hygiene. Please observe
the information under11.3.

11. Cleaning
Clean the coffee machine carefully in compliance
with the following instructions to maintain the value
and hygiene of the unit.
11.1 Cleaning intervals
 Daily cleaning of all systems (brewing, milk and
instant system), which have been used at least
once, and emptying the grounds drawer is man-
datory.
 If the coffee machine or a system has not been
used longer than 7 days, cleaning must be per-
formed before the machine is taken into opera-
tion again.
 Housing parts and strainer in the fresh water
supply (if present) must be cleaned on a month-
ly basis.
 Before switching off, we recommend that you
clean all the systems you have used.
a) Cleaning request
This flashes on the display, if …
 one of the cleaning intervals programmed under
10.6 b) has been exceeded ...
 and the machine has been operating for at least
1 hour since the last cleaning cycle …
 and at least 1 product has been dispensed.
During the cleaning request the products partly re-
main visible in the background and can still be dis-
pensed for a short period of time.
b) Automatic dispensing lock
The products are no longer displayed and dispensing
is blocked until the next cleaning, if ...
 more than 50 products have been dispensed
or more than 3 hours have passed since the
appearance of the cleaning request,
 or if more than one week has passed since the
last cleaning of the system.
 The corresponding systems must first be
cleaned, before the cleaning request or dispens-
ing lock can be reset.
11.2 Cleaning agents
 Use only cleaning solutions mentioned in the
instruction manual, because these have been
optimally matched to the automatic cleaning pro-
gram:
 Melitta®Cafina®Combi tablets
 Melitta®Cafina®AMC
Caution when using cleaning
agents!
mCleaning agents may be a health hazard when
swallowed, inhaled and in contact with skin.
Make sure that …
 Do not feed or insert cleaning solutions into
containers other than the ones described in
these instructions,
 any information on cleaning agents must be
easily accessible also in emergency situations.
If you are using the agents recommended by
Melitta this information is enclosed with each
of the solutions.
 Keep cleaning solutions out of the reach of
children.
 Wear suitable protective gloves.
 Follow the warning notes on the cleaning solu-
tions containers.
11.3 If you are working with canisters
 Empty both canisters daily! Do not leave any
residual water in them; fresh water can quickly
contaminate with mould spores.
 Also observe the water carbonate hardness
limit values with canister operation! The freshwa-
ter canister may need to be filled through the wa-
ter filter (Brita).
 Clean the fresh water container and its lid area
with a conventional dish washing agent and
thoroughly rinse off any cleaner residues before
each filling.
 Also clean the waste water container daily with
dish washing agent to avoid the development of
odours caused by organic residues in the waste
water.
 Clean also the strainer in the fresh water hose –
this is necessary with every machine mainte-
nance, but at least once every year. For this pur-
pose unscrew the front cap and rinse out the
strainer.
 Ensure that the fresh water container is filled with
enough water and that the waste water contain-
er is empty before you begin the cleaning pro-
gramme.

19
Warning!
When performing the cleaning activities, make
sure that the machine …
 is never subjected to pouring water and
 it is never spray clean with a hose.
 Also, do not spray clean the installation ar-
ea, e.g. with a water hose or high-pressure
cleaner.
mDanger to life from electrical shock may other-
wise occur from water entering the unit and
touching live parts.
mRisk of scalding! Do not reach into the dis-
pensing area during automatic cleaning.
 First pull out the power plug and allow the ma-
chine to cool down before performing cleaning
work on the machine by hand.
mYou thereby prevent the risk of injury from ac-
cidentally touching hot or moving parts during
cleaning.
11.4 Daily cleaning
It is not possible to dispense products during clean-
ing. Product dispensing can only be continued once
all containers have been reinserted.
