1.2.1 Various safety instructions
Introduction Below is listed the instructions divided into the hazard intensity levels
•Danger
•Warning
•Caution
Danger •Never insert the power supply plug of the machine in a wet or damp
socket. The plug itself must not be wet or damp either. Also never
insert or remove the plug from the socket with wet hands.
•Safety devices must not be bridged or put out of function.
•If the power supply cord of the machine is damaged, it must be
replaced by trained service technicians.
•Before cleaning the vending machine, ensure that it is switched off.
Warning •The vending machine must be connected to the mains in accordance
with all official regulations and local regulations laid down by the
electricity and water companies.
•Ensure that the supply voltage corresponds to the voltage indicated on
the rating plate which is located on the rear wall of the machine.
•The vending machine must be connected to an electric circuit which is
secured by an extra fuse. The connection to a supply with an integrated
fault current safety switch is recommended. If missing, we recommend
to install a fault current safety switch. The connection must be made
using an earthed safety plug socket complying with valid instructions.
•Check the drinking water quality prior to installation.
•The vending machine is suitable for indoor use only.
•Use only genuine spare parts when replacing components and / or
carrying out work on the vending machine, otherwise the manufacturer
will accept no liablility in the event of damage.
•Rinse the machine before putting it into operation.
•The beverages delivered by the machine are hot! In order to prevent
scalds, hands (and/or other parts of the body) must be kept out of the
drink delivery area during drink preparation and function tests.
•Keep children away from the machine!
•Carry out a functional test of the machine when the work is completed.
•Door switch:
When the door is opened, a special switch ensures that there is no
access to electrical or moving parts.
Any operation requiring the machine to be energized with the door
opened must be carried out exclusively by qualified technicians
informed about the specific risks of such situation.
The machine may be energized by qualified technicians by inserting

Service Manual FB 7100 Preface and safety instructions

the yellow service key into the door switch.
Before starting any maintenance or repair of energized or moving
parts, the machine must always be disconnected at the mains plug.
•When the yellow service key is inserted in the slot of the door key, the
machine is re-energized.
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.
Caution •To ensure proper hygiene and operation of the machine, it must be
cleaned regularly. Watch out for possible sharp edges when cleaning
the machine. Danger of scratches or cuts.
•Do not switch off the machine between beverage dispensings in order
to keep the optimum water temperature in the boiler. Set ‘energy
saving’ in programming instead.
•Clean the inside and outside of the machine using a clean damp cloth
and do not splash/rinse it. To clean the machine, only use cleaning
agents approved by the food industry.
•Never use high-pressure sprays for cleaning.
