Filling the machine with water from empty
Several restrictors are present within the machine. These restrictors slow down the flow within the
machine in order to optimise the coffee extraction process in terms of pressure profiling and
temperature stability. While filling the machine from empty, the fill restrictor hampers free flow to the
steam/hot water which may thus not fill up as quickly as you possibly expect.
As a safety measurement, the main controller shuts the machine down when any solenoid valve in the
machine (apart from the steam solenoid valves) is open for more than 2 minutes continuously (to
prevent flooding of the establishment in case of a malfunction).
Caution!
Although the coffee boilers start filling as soon as the water mains are opened, the boilers
cannot completely fill up because the air inside cannot escape from the groups. The boilers will only fill
until the air inside is compressed to water mains pressure. Therefore,
engage the temperature
controller on a coffee boiler only after water has run from the group
.
Figure 20. Showing the temperature controllers and their ON/OFF switches of the steam boiler and
both groups on a Spirit Duette
. Switches are in “OFF” position with levers pointing down, displays are
not lit.
Procedure
1. If present, remove the filter holders from all groups.
2. Make sure that a
ll temperature controller switches (PID’s for all groups plus the controller for the
steam boiler) are in the “OFF” position (lever pointing down, see Figure 20).
3. Make sure that coffee pressure gauges indicate line pressure. If not, check water connections.
4. Turn the mains
switch on the machine to “NO HEAT”. The mains switch is mounted on the right
hand side of the machine (see Figure 17). The machine will wait for approximately 3 seconds
before activating the pump and starting to fill the steam/hot water boiler. (Power to the heating
elements is disconnected for 3 reasons: 1-
mains switch is in position “NO HEAT”, 2- The
temperature controll
ers are not switched “ON” yet, 3- Safe water level in the steam/hot water
boiler is not yet reached.)
Note!
As the machine shuts down when the fill valve is active for more than 2 minutes continuously,
the operating level will not be reached yet.
5. While the steam boiler is filling activate the groups (
Bastone
: shortly press programming button;
touchpad
: shortly press top button) one by one to engage the group solenoid valve and pump and
bleed all air from the corresponding coffee boiler.
Deactivate the group (tap brewing lever down or shortly press top button) when water flow from
the group is more or less continuous.
Note!
The electronic temperature controllers just behind the drip tray can only be activated when the
safety water level inside the steam boiler is reached. (The heating elements should of course at all
times be immersed in water when operated.)
