1.1 Boiler System
Turn on the device using the ON/OFF switch. The display will light up.
The magnetic valve (fig. 1-10) will open and the hot water reservoir (fig. 1-9) will be filled to the
maximum electrode. The heating element will be switched on. The display shows [ boiler filling ] and
[ boiler heating ]. As soon as the NTC sensor measures the set temperature, the heating element will
be switched off.
When a drink is being dispensed the water level drops and the maximum electrode is released;
the inlet valve (2.5 litres/min.) opens and immediately refills the reservoir until the maximum level
is reached again. If the water level falls under the minimum electrode level during operation, the
operating panel display will show [refilling boiler]. If the supply of water is not restored within 90
seconds, the display will show the error message [E3 level error] and shut off the inlet valve.
1.2 Temperature regulation
The heating element is turned on when the water temperature falls below the temperature setting and
the minimum electrode registers water. The temperature in the water reservoir is measured using an
NTC precision sensor mounted on the outside wall of the reservoir.
The water temperature also drops when drinks are dispensed. To avoid the temperature regulator from
responding too late, the heating element is switched on as soon as the inlet valve (fig. 1-10) opens
and cold water is added. The heating element switches off again as soon as the inlet valve shuts
off. The software can also be used to delay when the heating element switches off. See menu item
2.4 Settings / Temperature in the service menu. The heating element always switches off when the
maximum boiler temperature of 97˚C is reached.
1.3 Hot water dispensing
When dispensing drinks one of the dispensing valve (fig. 1-8) opens and hot water flows to the brewer
or mixer system. The flow velocity for each valve is set using the adjustment screw on the valve. The
amount of outflow is determined by the length of time that the valve stays open. In order to rinse the
brewer unit and mixer system, a small amount of rinsing water is released shortly after dispensing to
rinse away any ingredient residue.
1.4 Cold water dispensing (optional)
OptiFresh has a built-in cold water option + special base cabinet with built-in cooling unit. When
dispensing a cold-water recipe, inlet valve DV6 opens (fig. 1-21) and allows water to flow from the
mains to the cooling unit cooling coil (fig.1-20). The cooled water already present flows directly to
the cold water outlet (fig. 1-19). As soon as the valve shuts off again the cold water dispenser stops
immediately.
1.5 Ingredients and mixer system
The ingredients canisters (fig. 1-11) are powered by a 130RPM motor (fig. 1-12). The instant product
(ingredient) is forced out of the canister by a coil and drops through the dispensing bent pipes into the
mixer unit (fig. 1-17). At the same time, the dispensing valves (fig. 1-18) dispense hot water into the
mixer unit. The mixer motor (fig. 1-15) blends the instant product with water at a speed of 10,700 RPM
using the mixer rotor (fig. 1-16). The drink flows into the cup via the drink outlet (fig. 1-3). All individual
parts mentioned in this section can be sequentially coordinated using adjustable
parameters (timers) in the control unit.

05/2008 Rev. 0.6 47
1.6 Evaporation extractor system
Evaporation released during mixing is largely absorbed by the evaporation extractor ring (fig. 1-18)
and sucked into the machine via the filter cassette (fig. 1-14). The evaporation and ingredient residue
are absorbed by the filter. The filter (fig. 1-14) can be easily reached (for cleaning purposes) by
dismantling the mixer unit (fig. 1-17). To a large extent, this prevents evaporation from entering the
canister outlet and making ingredients damp.
1.7 Brewer unit
Ground coffee and hot water are dispensed to the permanent filter and are drawn into the filter by
vacuum. After making a fresh brew drink selection the following process (fig. 2) starts:
Start
position
Brewer in resting position. Start
brewer 3
The piston moves down and sucks
the coffee extract through the
permanent filter.
Start
brewer 1
The piston leaves the resting posi-
tion. Ground coffee and hot water is
dispensed to the brewer unit.
Pause 3 Just before the coffee extract
leaves the brewer the piston either
pauses or stops again to make
sure the coffee residue is suf-
ficiently dry.
Pause 1 The piston stops just above the
outlet. Coffee and hot water is still
dispensed.
Start
brewer 4
The piston moves down further so
that the outlet opening opens.
Start
brewer 2
The piston rises and forces air
upwards out of the cylinder, ensur-
ing that coffee and water are mixed
thoroughly. Water dispensing stops
during this cycle.
Pause 4 The coffee is now dispensed to the
cup, goblet or jug.
Pause 2 Piston stops at the highest setting to
enable the coffee to be extracted.
Return to
start
The piston returns to the start
position again. At the same time
the coffee residue is wiped away
by the filter wiper, before it drops
into the waste bin.

1.7.1 Adjustment
If a leak occurs between the brewer unit and the
permanent filter the tensile force of the brewer needs to
be increased.
The tensile force of the brewer should be set so that no
water is able to leak between the brewer unit (fig. 3-1)
and the permanent filter (fig. 3-3).
The tensile force also ensures that the wiper (fig.
3-4) completely pushes the coffee residue off of the
permanent filter.
See figure 3 for the most important brewer parts:
1. Brewer unit
2. Rubber seal (Art. No. 03375)
3. Permanent filter (Art. No. 03374)
4. Wiper (Art. No. 03380)
5. Tension member
6. Adjustment shim* (Art. No. 03384)
7. Rubber
8. H-frame
9. Tension member adjustment
1. First remove the brewer from the device (see section
8.7.2 for instructions).
2. The tensile force can be set by adding adjustment
shims (fig. 3-6) between the tension member (fig.
3-5) and the H-frame (fig. 3-8).
3. Press the H-frame downwards and take the tension
member out of the recess. Place an adjustment
shim* in the recess and replace the tension member.
CAUTION: adding multiple shims at the same time
can cause excess tensile force and damage the
brewer!
4. In most cases this procedure is sufficient for
repairing leaks. If the brewer unit still leaks fit
another adjustment shim.
5. If the brewer unit still leaks remove the two
adjustment shims and then turn in the tension
member once (clockwise). CAUTION: turning in the
tension member should only be done as a last
resort.
6. If the tensile force is correct but the brewer still leaks
do not increase the tensile force any more! For
further help see chapter 1.7.3 Troubleshooting.

1.7.2 Setting tips
Tensile force too low (fig. 4) Tensile force correct (fig. 5) Tensile force too high (fig. 6)
If the wiper moves over the
upper side of the cylinder it
makes no
contact with the permanent
filter, so that coffee residue is
left on the filter. The wiper does
not bend at all.
If the brewer unit is adjusted in
this way it can leak. If leakage
is severe
this can even result in a
vacuum loss, which means
that the coffee residue remains
too wet (particularly for larger
dispensing volumes).
If the brewer is adjusted
correctly, the wiper moves
carefully over the upper side
of the cylinder and pushes
the coffee residue off of the
permanent filter. The wiper
bends slightly.
When the wiper moves to
the right the coffee residue is
transported to the waste bin.
The coffee residue drops from
the right side of the brewer
straight into the waste bin.
If the brewer is adjusted too
high, the wiper will stretch
and become clearly warped.
Glancing along the long side of
the wiper will show a warped
effect in the rubber.
The brewer is under extreme
pressure and the sound of the
brewer motor audibly changes
as a sign of the severe load.
This may even damage the
wiper!
During the complete brewer
cycle, ball bearings from the
wiper arms and the tension
member are under severe
pressure, resulting in bending.
The ball bearings may then
break away, cracking the plastic
brewer housing.
Signs that the tensile force is too high (fig. 6):
The wiper is severely bent when it slides across the upper side of the brewer cylinder and•
permanent filter.
It appears as if the wiper arm is flattened between the brewer unit and the upper side of the•
brewer cylinder.
The brewer motor sounds as though it is running under extreme pressure.•
The wiper pushes against the coffee residue when moving to the left.•
Accumulation of coffee residue round the waste bin.•

coffee residue when moving to
the left.
The brewer unit does not rise
far enough.
The brewer unit is hindered
during the upward movement.
Check if the brewer unit is able
to move upwards freely.
The brewer unit tensile force is
too high.
Remove one adjustment shim
to reduce the tensile force.
The coffee residue remains
too wet.
Never increase the tensile force
under if the brewer unit tensile
force is set correctly.
There is inadequate suction in
the coffee residue.
Increase the pause 3 time (see
section 1.6)
The water temperature is too
high.
Lower the water temperature.
The permanent filter is dirty or
worn.
Clean or replace the permanent
filter.
If the above-mentioned problem
is not resolved:
Check the brewer unit and
cylinders for fractures.
Replace the defective parts.
Check the cylinder for wear
and tear or scratches.
Replace the defective parts.
Check the Teflon coating for
wear and tear.
