Page 3: Designation
Designation This manual applies to the Slim Jim Mirage 2-group (Duette) and 3-group (Triplette) espresso machines with touchpad or Bastone operation manufactured by Kees van der Westen Espressonistic Works B.V. A separate rotational pump with electric motor is part of the appliance. -
Page 4: Water Quality
CONTENTS 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 higher part of the SCA “core zone”, see Figure 1, and have a pH of 7.0-7.5 (at 25°C). -
Page 5: Parts Identification
WELCOME Parts identification Figure 2. Showing the main operational parts of the Slim Jim Duette Bastone version. The Slim Jim Triplette has three groups but its functions are identical to the Duette. On the Touchpad version, the group brewing handle units are replaced with touchpads (see Figure 5). 1. -
Page 6: Operational Features
USER MANUAL - operation Operational features MAIN switch Notes! The machine will re-start over and over again when the capacitive screen is touched during start-up. Dirt and remnants of detergent may unexpectedly activate the capacitive screen. If the machine does not start up properly, clean the surface of the capacitive screen with plain water and a soft cloth. -
Page 7: Bastone Unit
USER MANUAL - operation Bastone unit start/stop A Bastone unit includes a brew handle, an volumes indicator LED, a momentary push button and a two-position toggle switch. Shortly pressing the brew handle down will start the pre-set volume determined by the toggle- switch. -
Page 8: Temperature Display
USER MANUAL - operation 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. Figure 6. -
Page 9: Pressure Gauge
USER MANUAL - operation 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. -
Page 10: Steaming
USER MANUAL - operation Steaming The Slim Jim has two identical mechanical steam valves that come in two versions: “twist-knob” and “flip-flop”. The twist-knob version 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. -
Page 11: Control Panel
USER MANUAL - operation 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 but increasing pressure before high water pressure is reached. With reduced flow-rate during pre-infusion it will take longer to wet all coffee 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 less permeable to the later inflow. -

Page 15: Use External Temperature Sensor (Option)
USER MANUAL - operation Use external temperature sensor (option) An external NTC-sensor can be plugged into the bottom of the electrics tray (see Figure 21, page 28). The temperature of the external sensor can be shown on the control panel instead of the steam boiler temperature. -
Page 16: Program Volumes With Touchpad Or Bastone
USER MANUAL - operation 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. -

Page 21: Adjust
USER MANUAL - operation 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 14: First loosen the plastic locking nut, then twist the set-screw until the desired pressure is reached and fasten the locking nut again. -
Page 22: Daily To Weekly Maintenance
USER MANUAL – routine Daily to weekly maintenance Use hot water from the machine Even the best treated water will lead to scale deposition in the steam boiler when the steam boiler is predominantly used to steam milk. If the hot water-tap on the espresso machine is hardly ever used get into the habit of doing your daily clean-up up with mix-water drawn from the espresso-machine instead of from the buildings hot-water supply. -
Page 23: Clean Filter Holder
USER MANUAL – routine Figure 16. Pry filter basket from filter holder with the group screen extractor. Clean filter holder Remove the filter basket from the filter holder and clean the filter basket with a little washing up liquid and plastic scouring pad or firm brush. Soak the metal part of the filter holder for 10 minutes in a solution of 1 tablespoon of coffee dissolving powder in 0.5 litre hot water. -
Page 24: Clean Group Screen, Check And Replace Group Seal
USER MANUAL – routine 4. Scoop 1 teaspoon of coffee dissolving powder in the blind filter and lock the filter holder in the group. 5. Activate the group, keep activated until full 9 Bar pressure is reached. 6. Then de-activate the group and wait until all pressure has dropped, do not remove the filter holder. 7. -
Page 25: Clean Group Dispersion Plate
USER MANUAL – routine Clean group dispersion plate The group dispersion set ensures uniform wetting of the coffee bed. When dirty, the wetting will become less uniform. As the dispersion plate and base are made of plastic material, which is heat neutral, no oils and fats will bake on easily and plate and base will remain clean for quite long. -
Page 26: Replace Dispersion Base And Plate
USER MANUAL – routine Replace dispersion base and plate The dispersion base and plate are sold as a set only (with new screws) as both parts deteriorate simultaneously. The protrusion on the dispersion base easily breaks off when the plastic material is affected (by cleaning powder). -

USER MANUAL – check condition Check pressure gauges 1. No pressure: when not brewing, the needles on all gauges should be in “resting position” (indicating close to 0 bar). 2. Identical pressure: with a blind filter in all groups, all groups active and all pre-infusion cylinders completely full, all gauges should display identical pressures. -
