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.

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].

Connect to water supply
Rated pressure: 0.1-0.5 MPa (1-5 bar)
Rated flow: minimum 4 litre/minute
The machine is equipped with a non-return valve that prevents water flowing back to the pump. The
pump itself does not have a non-return valve.
Note!
When installing a new machine, always use new water supply hoses.
Do not re-use the hoses from a replaced machine.
•Connect water tap to the inlet of the water treatment system with a suitable hose (not included).
•Make sure the water treatment system has been flushed according to the manufacturers
specifications.
•Close water mains.
•Use one of the supplied high-pressure hoses to connect the outlet of the water treatment system
to the inlet of the pump. The connection on the hose is a 3/8”BSPP swivel-nut.
Note!
National rules/regulations may apply when the appliance is connected to the water mains.
•Mount the high-pressure hose that is connected to the machine onto the outlet of the pump.
•Open water mains.
As there now is water mains pressure onto the machine, the coffee boilers will start to fill while
compressing the air inside the coffee system.
Figure 5. Showing the water connections on the pump. Water mains will be attached to water
treatment system (not shown in the photo) and from there via the pump onto the espresso machine.
Note that the water treatment system and supply hose are NOT included in the shipment.

Connect to drain/waste
•Normally, the drain hose of the machine will already be mounted onto the machine. The drain
hose of the drip-tray is not yet mounted.
oSlide a hose clamp over the separate drain hose.
oPush the end of that drain hose onto the pipe of the drip-tray and tighten the hose clamp.
•Lead the two drain hoses to the waste of the location (with water lock!). To prevent clogging
and/or pinching, make sure the hoses slope down all the way between the machine and the waste
and make sure the hoses do not make a sharp bend or are led over a sharp angle.
•The drain runs off best when the end of the hose is above water-level in the water lock.
Figure 6. The drain hoses should not slope up (left) or make a sharp bend (centre).

First fill
1. (Verify that all 3 HEAT switches are in the OFF position: lever pointing down.)
With the water-mains open and electric mains connected, turn the main switch ON (right hand side
switch, toggle-lever up). The display will show a start-up window with software-version information
and then turn to stand-by (“NO HEAT”).

2. Touch the centre button to turn the machine ON, the display will change to:
operational window
(Triplette)
temperature too low
but no heating
command
On the Duette operational window, the GROUP 3 “button” is not present. All separator bars are grey
indicating that controller is not sending out any signal to heat.
3. At this point the pump will be activated and the steam boiler will start to fill. As the coffee system
up to now has been filled at water mains pressure, this will continue to fill due to the increased
water pressure. Listen if you can hear water flowing into the steam boiler. If you do not hear water
flowing, there may be a blockage in the fill-system that has to be resolved before continuing.
4. The controller has a safety shut-down when the fill valve is open for longer than 2 minutes. The
steam boiler will not be completely filled yet after 2 minutes and the controller will thus shut down
and the LED(s) on the Bastone units or touchpads will start flashing.
5. Switch the main switch OFF (toggle-lever down) and wait for the displays to go blank, then turn
the main switch ON again, wait for the NO HEAT window, then touch the “NO HEAT” button: filling
will continue after a few seconds.
6. During this second filling, safety-level in the steam boiler will be reached and the display will
change (grey separator bars turn orange) to show that a heating command is given by the
controller. Since the heat switches are still in the OFF position, the boilers will not heat up yet.

On the Duette operational window, the GROUP 3 “button” is not present. Safety-level in steam boiler
is reached. Orange separator bars indicate that the controller is sending out signals to heat to all
boilers. Heating up will start when the HEAT switches are in the ON position (see next section).
7. Activate all groups (push-button on Bastone or upper button of touchpad) until water runs from the
group, then de-activate the groups.
8. If the steam boiler is not yet filled after these 2 “runs”, the LED(s) will start flashing again; repeat
the turning OFF-ON procedure.
9. When the OFF-ON procedure has to be repeated more than 2 times, it is possible that the steam
boiler does not fill (quickly enough) due to blockage in the system or very low pump-pressure
setting. Check before continuing.
10. When the filling has stopped without the LED(s) flashing the steam boiler is filled up to operational
level.
11. Re-check if water is flowing from all individual groups upon activation of the groups.

12. Mount a portafilter with blind-filter in one of the groups and activate that group. After the pre-
infusion cylinder is filled the pressure should increase rapidly to about 9 bar on that groups’
pressure gauge, if not, adjust the pump-pressure (see Figure 10).
Note that lowering the pump-pressure will not have an effect on the pressure gauge as there is a
check-valve in the coffee system. De-activate the group, lower the pump-pressure and then re-
activate the group to check. Remove the blind filter after this initial adjustment.
13. Press the mix-water button to see if water is flowing from the spout (this will be at very low flowrate
as there is no steam pressure and thus no hot water yet).
14. Check the machine for leaks.
Figure 10. How to adjust the pump-pressure. Undo the locking nut, then twist set-screw to correct the
pressure. Tighten the locking nut when done. Re-check brew-pressure after tightening the locking nut.

Heat up
1. Switch all three heat switches ON (lever up). This allows power to be fed onto the SSR’s in the
machine.
2. Check if all the green indicator lights underneath the electrics box are lighting up (see Figure 11).
a. If a single indicator light does not light up, it is possible that the corresponding overheat
safety switch has cut-out during transport:
Turn the machine OFF (MAIN switch and all 3 HEAT switches), remove the appropriate
body panel and press the central button of the overheat safety switch inward to re-set (see
Technical manual).
b. If corresponding indicator lights of a heat circuit (e.g. both most left lights of each set) do
not light up it is possible that the corresponding auto-fuse has cut power to that circuit.
Open the electrics-box (see Technical manual) to check the circuit breakers.
Figure 11. Indicator lights (and external sensor jack) underneath the electrics box. In a Duette the
most right indicator (3) is not present. The above situation (all indicators are lit) indicates that all
heating elements receive power.
3. Check heating up: When all indicator lights are lit (see Figure 11), the boilers will be heating up
(unless the heating element is not functioning) and the temperature readings on the displays will
increase. The steam boiler temperature will initially only rise very slowly as the sensor is located
above the water level.

check if water flows from each group immediately). Mount a blind filter in the left group and
activate that group using the “continuous button”. Pressure will rise to pump pressure rather
quickly and then slowly rise to a maximum pressure: the expansion pressure. The cold water
heating up is expanding which leads to increasing pressure until the expansion valve starts to spill
drops of water into the drain. The expansion pressure should be in the range 11-13 bar (contrary
to other machines we made the expansion pressure cannot be adjusted on this machine).
5. This would be a good moment to set/adjust a few parameters in the “technician level” of the
controller:
On the touchpad: touch the “MENU” button, then the “SETTINGS” button, then the “TECHNIC
LEVEL” button. In the next window construct the technician password using the arrows (the
number 66666), then touch “ENTER”. In the next windows a service telephone number can be
stored, the level-probe sensitivity can be adjusted (low-medium-high, depending on water
conditions), the choice made between filling possible during brew or not, and the flow-meter type
adjusted (after changing flow-meters).

7. If not set correct at the factory: adjust the temperature display from °C to °F or vice versa in the
sub-menu “TEMP. SETTING”.
8. Check if the machine has warmed up to operational temperature on the “operational window” of
the controller (the orange separators in the boiler buttons have turned grey at some time).

9. Check the operational features of the machine:
a. Open the steam taps for 30 seconds to release the remaining air above the water level.
b. Operate the mix water dispensing button switch.
c. Operate the hot water dispensing toggle switch.
d. Activate each individual group.
e. Use a measuring cup (or scales) to check the “free flow rate” of each individual group
i. with 0.6mm jets it should be 100 - 120 ml in 15 seconds
ii. with 0.8mm jets it should be 200 - 240 ml in 15 seconds
iii. with 1.0mm jets it should be 300 - 360 ml in 15 seconds
f. Brew a first coffee on each group to test functioning of pre-infusion cylinders. This first
coffee will probably not be very tasty as the grinder may need adjustment.
g. With correct grinder-setting and coffee-bed preparation check the pump-pressure again,
adjust when necessary (see Figure 10).
h. Measure the mix-water temperature (first make sure steam boiler is at operational
temperature). Adjust temperature on inlet manifold when necessary (see page 19).
10. Check the machine for leaks.
11. Fill out he machine number and installation date on a service record and keep this with the
machine.
TIP
Print the service record pages from the User manual (see Figure 12).

Adjust mix-water temperature
The temperature of the mix-water depends on:
1. the steam boiler temperature,
2. the temperature of the cold water,
3. the amount of mixed-in cold water, which depends on:
a. pump-pressure,
b. cold-water orifice.
4. the temperature of the inlet-manifold.
Before adjusting the mix-water temperature make sure that the machine is (otherwise) fully operational
and adjusted:
1. steam boiler at operational temperature,
2. pump-pressure adjusted to correct brew pressure.
The temperature of the manifold changes during use of the machine and this variation cannot be
compensated for. For that reason we suggest to measure the mix-water temperature of a second
dispense (appr. 100 ml) very shortly after a first dispense (100 ml) of mix-water.
The cold-water orifice can be adjusted on the inlet manifold inside the machine. The left side-panel of
the machine has to be removed to access the inlet manifold.
Figure 13. Undo the nuts and remove the left-hand side panel (when glass side panels are mounted
you have to remove the underlying support nuts as well to be able to remove the inner panel).
