Designation
This manual applies to the Speedster espresso machine manufactured by Kees van der Westen
Espressonistic Works B.V. A separate rotational pump with electric motor is part of the appliance.
Precaution
Hot surfaces!
Parts of the machine will be hot when the machine is turned ON.
•The metal cup tray heats up by way of radiation of the boilers inside the machine and can reach
temperatures up to 75°C.
•The metal group is intended to radiate heat and can possibly reach a temperature of up to 99°C.
Hot water and/or steam!
When the machine is heated up, hot water and steam can escape from various parts of the machine
upon manipulation of a corresponding interface (valve, switch, touch-button, …).
•Activating the group will lead to water being dispensed with a temperature of up to 99°C.
•Activation of the hot water dispense can lead to steam escaping with temperatures up to 135°C as
well.
•Activating the mix-water dispense can lead to overheated water (steam) being dispensed when
the cold-water addition is not set correctly.
•Opening the steam tap will start steam escaping from the steam wand-tips, the steam can reach
temperatures up to 135°C.
Safe operation
•The espresso machine has to be placed in a horizontal position on a sturdy and flat surface.
•If the supply cord or pump 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.

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).

Table 1. Showing parameter values for water meant to brew coffee with.
Water with properties that lie within the SCA “core zone”and has 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.

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 1) 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 a drain hose attached to the drip tray. This semi-flexible hose has an external
diameter of 20 mm (inner diameter: 15 mm). The hose 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 20 mm to accommodate for the hose 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.
Surface
The countertop must be sturdy enough to easily support the machines’ weight (when filled: up to 50kg)
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 with plug.
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.
