GENERAL
Slim Jim Installation manual page 2
Designation
This manual applies to the 2-group and 3-group Slim Jim Mirage 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.
Safe operation
•The espresso machine has to be placed in a horizontal position on a sturdy and flat surface.
•If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or
similarly qualified persons in order to avoid a hazard.
•The new hose-sets supplied with the appliance are to be used. Old hose-sets should not be
reused.
•Intended use of the appliance is restricted to well-trained personnel only.
•The appliance must be installed in locations where it can be overseen by trained personnel.
•The appliance may not be left unattended when there is the possibility that children and/or
vulnerable people can reach the machine.
•This appliance can be used by children aged from 8 years and above and persons with reduced
physical, sensory or mental capabilities or lack of experience and knowledge if they have been
given supervision or instruction concerning use of the appliance in a safe way and understand the
hazards involved. Children shall not play with the appliance. Cleaning and user maintenance shall
not be made by children without supervision.
•The mains electricity the appliance is connected to must include a residual-current-circuit-breaker
of 30 mA.
•The appliance may not be cleaned with the aid of a water jet.
•The appliance is not suited for outdoor use.
•Ambient temperature for correct operation of the appliance is 10-30°C (50-86°F).
•If ambient temperature falls below 5°C (41°F), keep the machine at ECO or ON to prevent freezing
of water inside the machine.
Note that the external rotational pump should be kept above freezing point of water as well.
Whenever the machine and/or pump have suffered freezing conditions, ask a technician to start-
up the appliance again.
•It is advised to install a leak prevention system as the appliances is directly connected to the water
mains. An unattended leak can cause serious damage to the premises.

Water Quality
Have the local water tested and ask the water supply company if there can be seasonal changes in
water quality and when so, in what order these changes occur. Install a suitable treatment system that
at least includes a carbon block in order to 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 high end of the SCA “core zone”,
see Figure 2, and have a pH of 7.0-7.5 (at 25°C).

Table 1. Showing parameter values for water meant to brew coffee with.
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. High brew-ratio’s, as for espresso, shift the optimum of total hardness and
alkalinity towards higher values within the core zone.

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.

Water supply
Rated pressure: 0.1-0.5 MPa (1-5 bar)
Rated flow: minimum 4 litre/minute
The water supply should be able to deliver a minimum amount of 4 litres per minute in the range 0.1-
0.5 MPa (1-5 bar). The machine and accompanying rotary vane pump must be connected with the
supplied new set of high-pressure hoses (two hoses, each 1.5 meter long), old hose-sets should not
be re-used. The distance between water treatment system and pump and the distance between pump
and machine cannot be greater than 1.5 meter unless there is appropriate material available to
increase these distances.
Notes!
Not included in the shipment are supplies to make the connection between the water-tap and the
water treatment system.
National rules/regulations may apply when the appliance is connected to the water mains.
Water treatment system
The water treatment system should also be able to deliver a minimum amount of 4 litres per minute
and 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.
If the resulting water does not fall into the SCA “core-zone” (see Figure 2) have additional treatment
installed.
Notes!
Flush the water treatment system according to the manufacturers instruction before connecting it to
the pump-inlet.
Make sure that the functioning of the water treatment system will be checked on a regular basis.
Waste/drain
The appliance has two drain hoses: one for the drip tray and one for the machine itself. These semi-
flexible hoses have an external diameter of 20 mm (inner diameter: 16 mm). The hoses must slope
downwards all the way from machine to waste to prevent clogging. The waste at the location should
have a minimum inside diameter of 38 mm to accommodate for the two hoses and incorporate a
water-lock to prevent smelly odours.
Machine location
The machine is only to be installed in locations where it can be overseen by trained personnel.
Areas where a water-jet could be used are not suitable as location for the machine.
Counter surface
The countertop must be sturdy enough to easily support the machines’ weight (when filled: up to
100kg) plus extra equipment (one or two coffee-grinders, tableware, …). The surface should have a
height of 95-100 cm and be smooth, flat and horizontal.
It is advised to think about the location of holes in the countertop where the water and waste hoses
and electric cables should pass before the machine is installed.
Pump location
There should be nearby space for the electric motor with rotary vane pump. The pump-assembly
should not be able to touch the walls of the cabinet it is located in to prevent noise. Further noise
reduction can be achieved by placing the assembly on a 2-4cm thick rubber-foam sheet with
dimensions: 16x30cm (not supplied with machine). The pump will be electrically connected to the
espresso machine with an approximately 2 m long cable.
Areas where a water-jet could be used are not suitable as location for the pump-assembly.
Make sure there is air-flow possible near the motor to prevent overheating.

Rated voltage: ~230V / 3N~400V, 50 / 60Hz
Rated power: max. 34.7 (230V) / 11.6 (400V) Amp per phase, see Table 2 for details.
Danger
If the supply cord or the pump connection cord is damaged it must be replaced by the manufacturer,
its service agent or similarly qualified persons in order to avoid a hazard.
The appliance is to be supplied through a residual current device (RCD) having a rated residual
operating current not exceeding 30mA.

Table 2. Showing peak power in the different phases for different machine versions.
The machines’ internal electrics consists of 3 heating circuits and an operation circuit. Each circuit is
meant to function on 230Vac. The range in which it can function safely is 208-240Vac. Electric mains
can be connected in two ways to the machine. Check if the electric mains of the location matches the
configuration of the machine.
3-phase machine
What we call a three-phase machine must be connected to 3P-N-E power (3 Phases + Neutral +
Earth, see Figure 3) with 120 degrees phase shift between phases. Such power is characterised by:
220-240Vac tension between each phase and neutral (or Earth) and 380-400Vac tension between the
phases. For peak power, see Table 2.

single-phase machine
What we call a single-phase machine must be connected to P-N-E (single Phase + Neutral + Earth) or
2P-E (split Phase + Earth) power mains, see Figure 4. Note that the 2P-E configuration does NOT
make use of the neutral wire of the electric mains. For peak power, see Table 2. The tension between
the phase and neutral (P-N-E power) or the tension between the two phases (2P-E power) should be
220-240Vac.
Note that with single-phase peak current in the mains cable and the locations’ wiring is a lot higher
than with 3-phase power.
Figure 4. At left P-N-E, at right 2P-N-E. The machine can make use of L1 and L2 plus E (without N) of
the right electric mains configuration. Peak current is 27.5-34.7A.
3-phase / single phase conversion
The machine will be prepared in the factory for connection to either 3P-N-E or P-N-E/2P-E power and
will show respectively 3N~400V or ~230V on the identification tag.
Conversion is possible but requires replacement parts. Replacement parts and instruction for the
conversion can be obtained at: [e-mail].
Note!
National rules/regulations may apply when the appliance is connected to the electric mains.
