INTRODUCTION
According to the requirements of the
customer, the service technician can
program different functions into the vending
machine.
The machine dispenses
•hot espresso drinks
•hot instant drinks
•hot water.
or
•hot espresso drinks
•hot/cold instant drinks
•hot water.
Use only fresh coffee beans or instant
products made for vending machines.
The machine is delivered with direct selection
buttons. All communication with the machine,
such as drink selection, rinsing functions,
data retrieval and settings, is carried out by
using the direct selection buttons.
All parts to be cleaned are designed in a light
blue colour (for regular cleaning) and in a
dark blue colour (for deep cleaning). All parts
of action are supplied in a green colour.
If the vending machine is not used according
to its purpose, the manufacturer cannot take
on any liability.
This operator manual is valid for several vari-
ants of the vending machine. Therefore, it is
possible that in this operator manual you may
find instructions for operating elements that
are not installed in your vending machine.
This technical documentation is part and
parcel of the vending machine and must
always follow the machine in case it is moved
or by transfer of ownership.
This appliance is not intended for use by per-
sons (including children) with reduced physi-
cal, sensory or mental capabilities, or lack of
experience and knowledge, unless they have
been given supervision or instruction con-
cerning use of the appliance by a person re-
sponsible for their safety.
Children should be supervised to ensure that
they do not play with the appliance.

Safety
2ES 7100 PLUS 10.2011
SAFETY
•Before starting installation and using the
machine, it is first necessary to carefully
read and understand the instructions
contained in this manual, as they offer
important information on installation
safety, operating instructions and
maintenance.
•This manual describes the loading and
routine maintenance operations which are
carried out in areas of the machine
accessible with simple use of the door
key, without using any other tools.
•The vending machine may not be subject
to frost during operation, storage and
transport.
- If there is the risk of frost in the area of
the installation site of the machine,
voltage to the machine may not be
disconnected.
- If there is the danger of damage due to
frost, the service technician must check
and replace boiler, hoses and valves if
required prior to reconnecting the
vending machine and he should
additionally carry out a functional test.
•The vending machine may not be installed
outside.
•The vending machine should only be
installed and repaired by qualified
personnel, who are trained in the correct
use of the machine according to the
standards in force and who have the
specific knowledge of the machine
functioning from a point of view of
electrical safety and health regulations.
•Safety devices must not be bridged or put
out of function.
•The vending machine must be connected
to the drinking water line and to the
electric line in compliance with local
regulations.
•The vending machine has to be placed in
a horizontal position.
•The vending machine must be connected
to a secured electric circuit.
We recommend to install a fault current
safety switch. The connections must be
made using an earthed safety plug socket
complying with valid regulations.
•After the machine has been installed, the
power supply plug must be accessible.
Never touch the power supply plug
with wet hands or plug it in if the
plug itself is wet.
The liquids dispensed by the vend-
ing machine are very hot! To pre-
vent scalding, hands (and/or other
parts of the body) must be kept
away from the outlets while drinks
are being prepared and dispensed.
•If the power supply cable of the vending
machine is damaged it may only be
replaced by a service technician.

Safety
10.2011 ES 7100 PLUS 3
•Do not attempt to fill several cups by
pressing the pot button. There is danger
of injuries.
•Only authorised and qualified personnel
may clean, fill up and set the vending
machine.
•The vending machine may not be cleaned
under a water jet and is not suitable for
installation on surfaces next to which
water jets are being used (e.g. for
cleaning).
•Use only original spare parts.
•Observe the local regulations!
•Regular cleaning of the vending machine
is necessary for functional and hygienic
reasons.
When cleaning, take care of sharp
edges. There is danger of injuries!
•To clean the cabinet only use cleaning
agents approved by the food industry.
•Clean the inside and outside of the
vending machine by using a damp cloth
and do not splash it.
•After cleaning, make sure that all
components are correctly reinstalled.
•Every machine is identified by its own
serial number indicated on the rating plate
attached at the rear of the vending
machine. This plate is the only one
acknowledged by the manufacturer as
identification of the machine. The
technical data of the vending machine are
given on the rating plate.
When the yellow special key is in-
serted in the slot of the door switch,
the voltage is re-established to the
machine.
The door can be closed only after
removing the key from the door
switch.
If power is turned on, be careful not
to touch moving parts and electrical
components.
Door switch:
When the door is opened, a special
switch ensures that there is no ac-
cess to energized or moving parts.
Any operation requiring the ma-
chine to be energized with the door
opened must be carried out exclu-
sively by qualified personnel in-
formed about the specific risks of
such situation.
The machine may be energized by
qualified personnel by inserting a
special yellow key into the door
switch.
Before starting any maintenance
operation requiring parts of the es-
presso brewer unit to be removed,
the machine must always be
switched off.
By means of class 1 LEDs.
LEDSs are generally shielded by a
glass front or an aesthetic panel.
The light of LEDs may be noxious if
you directly look at it without these
panels.
