2.1.4 Hygiene measures
When carrying out maintenance work, hygiene measures must
be observed during every stage of work. This is also a re-
quirement of materials used. Besides taking personal hygiene
measures, such as wearing clean work wear, you must also
pay attention to cleanliness of tools and spare parts. There
must always be sufficient cleaning materials available for the
job in hand (large and small brushes, cloths, vacuum cleaner
etc.)
Occasionally these cleaning materials must be supplemented,
replaced, maintained and/or repaired.
2.1.5 Booster / Hotflush
Two machine series which differ greatly in design are de-
scribed and illustrated in this manual:
 Machines without boosters but with flush valve and a
complex temperature control for the instant heater
over-temperature 1/over-temperature 2. Refrigerator with
cold water rinse.
 Machines with boosters and refrigerator unit with hot
water rinse (HOTFLUSH).
The corresponding changes to the coffee machine were im-
plemented to the refrigerator simultaneously. The machine
series differ by serial number and a certain production date.
Reference is made to these dates in this manual in all sections
which contain both descriptions. Illustrations generally have a
BOOSTER or HOTFLUSH „stamp".
Series number and production date
 Machines without boosters, with flush valve and their
refrigerator with cold water rinse:
Production date up to 1.4.2002
Serial number to 505123
......... 01.04.2002
......... Serial no. 505123
 Machines with booster and refrigerator with hot water
rinse (HOTFLUSH).
Production date from 2.4.2002 on or
Serial number from 505124
02.04.2002 .........
Serial no. 505124……
Illustrations with "Stamp"
The different and partially fundamental mechanical hydraulic
design of the machine is also resulting in corresponding
changes to the programming. Individual parameters can no
longer be set. Therefore, the corresponding settings must be
made for the booster (see "Programming manual").
Service tools and test instruments (see next page)
1 These tools and test instruments are the minimum items required to carry out maintenance work.
2 These tools and test instruments should also be available as a minimum stock of tools in order to carry out the highest
quality of maintenance work. These are principally instruments that provide good service particularly for repair work on ma-
chines. Specific fault diagnosis requires the corresponding relevant test instruments to enable individual systems and com-
ponents to be tested in a very flexible manner. Nowadays ESD protection equipment is considered to be basic equipment,
as are lubricants, to enable certain components to undergo perfect repair. The temperature gauge shown is an add-on to
the multimeter, but a separate temperature gauge may also be used.
3 Water hardness tester set A complete set contains all the test equipment and chemicals needed to ascertain carbonate and
overall hardness
4 Anti-static containers for flash-ROMs and EEPROMs
5 EEPROM extraction tool
6 Flash ROM extraction tool
7 Temperature gauge: can be an accessory to a multimeter or can be in the form of a separate measuring instrument
8 Antistatic mat with ground cable and wrist strap
9 Antistatic packaging for printed circuit board (Power PCB / EHS)
10 Scales and measuring cup or container to weigh ground coffee
11 Teflon tape in various widths
12 Insulating tape
13 Thermo conducting paste
14 Food grease
15 Grease for use with plastics
16 Micro brush
