Water Quality
Have a water treatment system installed and its function checked regularly. The treatment system
should at least have a carbon block that not only traps drug-remnants, Chlorine and organic
compounds but also prevents rigid particles >30 μm to enter the pump. Optimally, the water fed into
the espresso machine would fall in the SCA “core zone”, see Figure 1, and have a pH of 7.0-7.5 (at
25°C).

Water with properties that lie within the SCA “core zone”and correct pH combines technical aspects
enabling a safe operation and sensory aspects yielding a high quality brew, provided the other
parameters are met as well. Low brew-ratio’s, as for espresso, shift the optimum of total hardness and
alkalinity towards higher values.

The conversion from electrical conductivity to TDS depends heavily on the water composition and temperature, yielding results
that can vary significantly. Additionally, even if the estimated TDS value is accurate, it does not contain any information about
what the TDS is actually made up of.

Operational features
MAIN switch
The main switch (see Figure 3) is located at the right hand side of the machine and has 2 positions:
DOWN=OFF Power to the controller is disconnected. When the machine is functioning correctly, all
heating is also off, whatever the position of the heat switches. With a malfunction it is
however possible that one (or more) heating elements/sections are still active.
Depending on latent heat in the machine the brew will not be warm enough, hot water
will be at lower flow-rate and temperature and steam power is reduced or absent.
UP=ON The machine is connected to the electric mains, but power to the heating elements will
remain disconnected as long as the heat switches are still off. The machine functions
but the boilers will not heat. The optional cup-heater may function if it is turned on.
Figure 3. Showing the three HEAT switches, the MAIN switch and a blank TEMP/TIMER (3-digit)
display.
HEAT switches
Heating power to the machine is split in three different circuits. Each circuit can be (dis-)connected
individually. The heating element of the steam boiler consists of a lower middle and upper section.
Notes!
The boilers will not heat up when the HEAT switches are in the OFF position.
With the main switch in OFF position, the boilers will not heat up, irrespective of the position of the
HEAT switches.
1. HEAT 1 powers the left group heating element and the lower section of the steam boiler heating
element.
2. HEAT 2 powers the central (Triplette) or right (Duette) group heating element and the middle
section of the steam boiler heating element.
3. HEAT 3 powers the right group heating element (Triplette only) and the upper section of the steam
boiler heating element.
Circuit breakers
The machine has an individual breaker for each of the four electrical circuits in the machine (main-
circuit plus 3 heat-circuits). When one of the circuits has a malfunction (electric short), the
corresponding breaker will cut power to that circuit only. If the main-circuit breaker is activated the
machine will be completely inoperable but if a single heat-circuit breaker is activated the rest of the
machine will remain functional.
The circuit breakers are located within the electrics tray and cannot be accessed by the barista. If a
circuit breaker is activated, have a technician check and repair the machine as soon as possible.

USER MANUAL - operation
Slim Jim User manual page 5
Bastone unit
A bastone unit includes a brew lever, an
indicator light, a momentary push button and a
two-position toggle switch.
Shortly pressing the brew lever will start the pre-
set volume determined by the toggle-switch. A
pre-set volume can be stopped before the
volume is reached by shortly pressing the brew
lever again.
When the group is active, the indicator LED is lit.
The push button is the continuous (“on/off”)
switch with programming function.
The toggle switch determines which of the two
possible pre-set volumes is active.
Figure 4. Bastone unit.
The push button underneath each brew lever is the continuous (“on/off”) switch equivalent to button #5
on a touchpad (see below). The indicator light will light up continuously when the controller is in
programming mode. A continuous dispense can also be stopped by shortly pressing the brew lever.
Touchpad
A touchpad has 5 momentary push buttons with
internal indicator LED.
The upper button (#5, larger circle) is an on/off
group switch with programming function.
Buttons #1-4 are used to start a pre-set volume.
A pre-set volume can be stopped before the
volume is reached by shortly pressing any
button.
When the group is active, the indicator LED of
corresponding button is lit.
Figure 5. Touchpad.
Press the upper button briefly to open the group valve and activate the pump, the LED in the button
will light up. Press it briefly again to deactivate the pump and group valve, the LED will go off.
Press the upper button and keep pressed to get the controller in programming mode such that shot-
volumes (and hot water timer) can be programmed. The indicator LED of the upper button will flash
and the other 4 will be lit continuously. Press and keep pressed again to leave programming mode.
For shot-volume programming with bastone units or touchpads see page 14: Program volumes with
touchpad or bastone.

Temperature display
Each boiler is equipped with its own temperature controlling system. Measured temperature values
can be displayed 2-ways: on the control panel and/or on the large 3-digit displays underneath each
group (see Figure 6). In the barista menu, the temperature unit can be switched from °C to °F.
On control panel
At “normal” operation, the control panel will show the temperatures of all coffee boilers and the steam
boiler and and will continue to do so during a shot such that information about temperature is always
real-time available during a shot.
An orange line above a temperature value on the interface indicates that the corresponding heating
element is active.
Figure 6. Showing a 3-digit temperature/timer display (left) and the control panel (right).
On 3-digit displays
Factory setting is that a 3-digit display will display the temperature of the corresponding group during
idle. It changes to a shot-timer when the group is activated. The shot-time will be replaced by the
boiler temperature after a user-adjustable amount of seconds.
Shot time
The shot time gives an excellent indication of the brew process and can assist the trained barista to
refine that process.
The large 3-digit displays underneath each group (see Figure 7) function as shot timers and/or
temperature display. In factory setting the displays show at idle the temperature of the corresponding
coffee boiler. As soon as the group valve opens the function changes to shot timer, starting at zero,
and counting starts. The timer stops counting when the group valve is closed and the measured time
between opening and closing of the group valve remains displayed for an adjustable amount of
seconds after the group valve was closed upon which the display changes back to showing the
temperature.
Figure 7. A 3-digit display showing shot time (left) and the same display showing temperature (right).

USER MANUAL - operation
Slim Jim User manual page 7
Pressure gauge
While brewing a real shot the coffee-bed becomes less permeable during wetting (pre-infusion stage)
and pressure will rise until pump-pressure is reached (ideally 9 bar). The pressure gauges display the
pressure in the line that runs from group-valve to group-screen. This means that when a group is
inactive or when no portafilter is locked in, the pressure gauge will display 0 bar.
The pressure gauge shows the actual pressure
on the coffee bed.
When the group is inactive, the pressure
displayed is thus (very close to) 0.
Figure 8. The brew pressure gauge of group 2.
If 9 bar pressure is not reached during a normal brew, either the pump pressure is set too low or the
coffee bed was not able to produce enough counter pressure. Insufficient counter-pressure can be
caused by too few and/or too coarse coffee grinds, channelling in coffee bed during extraction, etc.
Dispensing hot water
Momentary toggle switch for dispense of water
directly from steam boiler.
Push-button switch for timed dispense of non-
sputtering mix-water.
Figure 9. The hot-water toggle switch and mix-water push button switch.
Mixed water
Press the mixed-water push button switch down briefly. The flow will stop when the pre-set time has
elapsed, or when the switch is pressed down briefly again, whichever comes first.
A technician can manipulate the cold inflow with a set-screw on the manifold inside the machine to
optimise the mix-water temperature.
Hot water
Press-hold the toggle switch down to start water flowing directly from the steam boiler to the spout. It
will take a moment before the water starts to sputter indicating that boiling water is being dispensed.
The duration of that moment depends on the temperature of the intermediate parts just prior to
pressing the switch. The flow will stop when the switch is released.
Note!
Hot water can only be dispensed when the steam boiler is above 100°C as steam pressure is the
means to push the water out of the boiler. When the steam boiler is not at operational temperature yet,
the mix-water temperature will be lower than the set temperature.

USER MANUAL - operation
Slim Jim User manual page 8
Steaming
The Slim Jim has two identical mechanical steam valves that can optionally be equipped with foot
operated solenoid valves.
Before steaming milk it is necessary to open the valve for a short while to purge water from the steam
wand and heat up the wand and valve. The purged water is condensate from steam coming in contact
with the cold tubing, valve and wand. Position the tip of the steam wand over the drip tray when
purging the condensate.
Directly after steaming milk, flush the steam wand with a little steam and clean the tip of the steam
wand with a damp cloth. For hygienic reasons, do not use this cloth for anything other than cleaning
the steam tip.
Twist the valve-knob to open/close and adjust
the steam flow. From fully open to fully closed is
about ¾ turn, there is no need to close the valve
firmly.
If the optional foot-operated steam valve is
mounted, do not fully close the mechanical
valve.
Figure 10. The right hand steam valve.
When the optional foot operated solenoid valve is mounted, the knob is used to adjust the flow of the
steam only. The solenoid valve will be opened and closed by an air-switch that is activated by a bellow
on the floor. Of course, when the mechanical valve is turned close, no steam will flow from the wand.
Note! It is advised not to decrease the steam power by lowering the steam boiler temperature. A lower
boiler temperature will reduce the amount of steam that can be produced and the temperature of the
mix-water dispensing.

USER MANUAL - operation
Slim Jim User manual page 9
Pre-infusion cylinder
The piston rod will rise up during the initial stage
of a brew. A double spring assembly inside the
pre-infusion cylinder assures a slow-starting and
gradual pressure build-up to about 3 bar when
the maximum displacement of the piston is
reached.
Figure 11. Piston-rod ends of the pre-infusion cylinders.
At the start of a brew water leaving the group-valve can go into the coffee-bed and into the pre-
infusion cylinder. The water will flow in the direction of the least back-pressure. At start the coffee-bed
will have no back-pressure but once the grinds are wetted, dominant water-flow changes towards the
pre-infusion cylinder. Pressure gradually increases until the cylinder is completely filled and all water
has to flow through the coffee-bed. From that moment brew-pressure quickly increases to pump-
pressure.
Caution! The piston-rod of the pre-infusion cylinder can become very warm.
The advantage of the pre-infusion cylinder over a reduced flow-rate at start is that the entire coffee-
bed will be soaked relatively quick and then has time to swell and settle at reduced pressure before
high pressure is established. With reduced flow-rate during pre-infusion it will take a longer time to wet
all grinds and swelling and setting of the coffee-grinds starts where water reaches the grinds first such
that the upper part of the coffee-bed becomes more impermeable to the later inflow.

Slim Jim User manual page 10
Control panel
The control panels of the Triplette and Duette are very similar and has a 5-“button” capacitive touch
screen. When at operation, the display will show the temperatures in °C or °F without the temperature
unit. The reason for this is that not showing the unit allows the use of a bigger font for the temperature
values. The user will be aware of the local unit-setting and realise that normal brewing is at 90-95°C or
187-203°F.

Change individual boiler to ECO and back
The factory set operational temperatures of the boilers are 93.0°C (coffee) and 125.0°C (steam)
(199°F and 257°F) respectively. 125°C is equivalent to approximately 1.35 Bar steam overpressure.
Each boiler can be individually set to a lower ECO temperature (50°C, 122°F for the coffee boilers,
70°C, 158°F for the steam boiler). At the lower temperature setting up to 80% power is saved while the
boiler will still have a short heat-up time. In the “operational window”of the interface, touch-hold the
button of the boiler that you want to change until the colour of the button-frame changes to green
(about 6 seconds). Touch-hold again and the corresponding boiler will heat up to operational
temperature again.
An individual group set at ECO will also turn to normal operation when the corresponding bastone unit
or touchpad is operated.
When the steam boiler is set to ECO, using any of the groups to make a brew or pressing the mix-
water switch will turn the steam boiler back to normal operation.

Go to stand-by
You have to leave the operational window to go to stand-by. In stand-by the controller is in sleeping
mode and the machine does not operate. There are two stand-by modes: “NO HEAT” and “ECO-
MODE”. At “NO HEAT” there is no power to the heating elements and the boilers will (eventually) cool
down to room-temperature. At “ECO-MODE” the boilers will cool down to a lower set temperature and
are then kept at that temperature.

Sensor malfunction
For each boiler sensor, the corresponding area in the display, as well as the 3-digit display, will show
O.C. (open circuit, infinite resistance) or C.C. (closed circuit, electric short) if there is a sensor
malfunction. When a sensor malfunction is shown for a boiler, the heating of that boiler is dis-engaged.
The machine will remain functional on the other boilers. When there is a steam boiler sensor
malfunction the indicator LED(s) on the bastone units or touchpads will flash continuously.
Even though the coffee boilers will remain operational when there is a steam boiler sensor
malfunction, overall functionality of the machine will be low. Have the machine checked as soon as
possible (probably you need to have the sensor replaced).
oprational window
a closed circuit is
detected at group 1

As the sensor in the heat exchanger manifold has no designated area on the control panel, a sensor
error is indicated by a red center line in all groups. There is no distinction between open or closed
circuit. With a malfunctioning sensor, the cool-valve will not open but the machine will remain
functional. A non-functional cool valve may lead to overheating of the groups and rapid decay of the
flow-meters in the machine. Have the machine repaired as soon as possible.

Program volumes with touchpad or bastone
The bastone version of the Slim Jim has 2 pre-set volumes per group, the touchpad version has 4 pre-
set volumes per group. When water flows through a coffee group, the flow meter of that group sends
pulses to the controller. The controller counts the pulses after activation of the group and will de-
activate the group when the pre-set number of pulses has been received (that is: when the pre-set
volume of water has passed the flow meter).
The pre-set volumes can be programmed 2-ways: with the bastone units or touchpads, or using the
interface (in the Barista-menu; submenu “volumes”).
When using the bastone or touchpad to program volumes, the left group is the dominant group
meaning that when a volume is programmed on the left group, the other group(s) will take over that
volume. After getting the machine to programming mode a shot is started and ended with the bastone
(or touchpad). Upon leaving the programming mode, the last programmed dispense for each shot
volume is stored in memory.
Make sure to mimic an actual brew while programming volumes: check that the machine is at
operational temperature for some time and prepare the coffee-bed as you normally would.
procedure
1. get the controller in programming mode:
•touchpad: press-hold the upper button of the left touchpad
•bastone: press-hold the push button of the left bastone
the LED(s) on all units will start flashing
2. start the brew/dispense as normal
•touchpad: shortly press the button to be programmed
•bastone: note the position of the toggle-switch, shortly pres the bastone lever down
•hot water: start the dispense by shortly pressing the dispense push button

Note that the volumes can also be set with the aid of the touchpads/bastone units. Only when volumes
are programmed with touchpad or bastone, the left group is dominant.
You can roughly program a shot-volume with the touchpad/bastone and then fine-tune that volume on
the control panel (increase or decrease) instead of brewing a new shot. Note that the volume shown
on the interface is the total volume that passes the flow-meter, it thus also includes the water that
remains in the coffee puck after the brew (appr. half the weight of the coffee-grinds) and the water that
flows into the pre-infusion cylinder (appr. 28 ml).

Timer function to switch the machine
The machine can automatically change state:

USER MANUAL - operation
Slim Jim User manual page 17
•Using the “auto off” function will turn the machine to stand-by (ECO or NO HEAT) at a pre-set
time (e.g. at the end of the day). It is especially meant to facilitate the use of the ECO function.
•Using the “auto on” function will turn the machine to operational temperature at a pre-set time
(e.g. in the morning). When set correctly, the machine will be fully operational the minute the
store opens.
•The “day off” function will make the pre-programmed ON time skip a weekday.
An automatically set switch can be overridden manually on the machine at any time. After such
interference the timer function will continue to run in the backgroud and will perform the next pre-set
action when it turns up.
Notes!
To have the machine react properly to the timer function instructions the main and circuit switches
must remain in the ON position.
The time and weekday of the controller must also be set correctly. It is advised to check these
regularly (present time and weekday are shown on the ECO-all and NO HEAT windows).
Why switch to ECO …
1. A machine kept at ECO consumes about 20% of the energy of a machine kept at operational
temperature.
Heat loss of the machine is related to the square of the temperature difference between the machine
and its environment. Of course some extra energy is needed to heat up from ECO to operational
temperature. Switching to ECO will therefore lead to 70-75% energy reduction, depending on how
long the machine will be at ECO.
… and not to OFF?
2. A lot of parts in the machine suffer from temperature variations, the more so when these variations
are large.
3. Heating up from ECO (just over 8 minutes) is faster than heating up from room temperature (about
15 minutes).
Figure 12. Graph showing typical heat-up duration normalised at ECO-temperatures. From ECO to
operational temperatures takes just over 8 minutes for both coffee and steam. From 20°C to
operational takes 14 (coffee) and 16 (steam) minutes resp.. Also shown is heat-up with high power
heating element for steam boiler.
Note! The temperature sensor of the steam-boiler is placed above the water-level for quick response
to steam withdrawal. At temperatures below 110 °C (230 °F) the sensor will not register a change in
(water) temperature quickly. For that reason, the steam-boiler temperature may be up to 6 °C higher
than the ECO-setpoint at the moment you switch from ECO to operational mode.

Pump-pressure
Check
Check the pump-pressure when an actual brew is at the infusion stage; i.e. the highest pressure
reached during a brew. Make sure that only a single group is active during this check as multiple
“users” will result in a somewhat lower pump-pressure.
Do not use the mix-water during this check as that will also result in some pressure loss.
Check all groups available and compare the results. The pump-pressure at the different groups should
be identical as there is only one pump used for the entire machine.
Notes!
A small divergency (<0.2 bar) between the groups can be the result of deviations between pressure
gauges and is no cause for alarm.
A large divergency may indicate a malfunction but can also be the result of different coffee-bed
preparation. Redo the check and have a technician solve the problem when the divergency persists.
Adjust
Pump pressure is adjusted on the pump by regulating the amount of by-pass of the pump-outflow.
Adjust the pressure when an actual brew is at the infusion stage (the more or less stable high
pressure during a brew).
See Figure 13: First loosen the plastic locking nut, then twist the set-screw until the desired pressure
is reached and fasten the locking nut again. Check the pump pressure again after the adjustment.

Cool down the machine
(re-locate to technical manual?)
As the steam boiler is isolated, the temperature in the steam boiler will drop very slowly when heating
is turned off and the machine is otherwise untouched. It will take about 5 hrs to cool down to its ECO
temperature of 70°C. The coffee boiler, which is not isolated, will cool down faster and will reach ECO
temperature (50°C) after 1.5-2 hrs.
Figure 14. Graph showing typical cool-down of the boilers when the machine is turned to “NO HEAT”
when it is at operational temperature.
If it is needed to cool down the machine quickly, turn the heating circuits to OFF and open both steam
taps until no more steam escapes from the tip. That will cool down water in the steam boiler to 100°C
but be aware that there will be some latent heat within the stainless steel of the boiler and heat
exchanger. Activate all groups continuously for a few minutes to have cold water running towards the
groups.
