Before proceeding with installation check that:
- there are no bumps, signs of knocks or deformities.
1 there are no damp patches or marks which could lead
one to assume that the packaging has been exposed to
the elements
2 there are no signs of tampering
Once one is satisfied that transportation has been correctly
effected proceed with installation.
Proceed with installation following the instructions according
to the sequence as described below.
N.B. The least height of the support's top must be 110cm.
5.1 Water connection
Important: The machine must be supplied with water
of over 8
°
F hardness.
The installation of a water softener is recommended for the
machine water supply.
Check that the water mains to which connection is to be
made supplies drinking water.
- Connect purifier (E) to the water mains (A).
NB: before connecting the purifier to the machine,
wash out thoroughly until the water becomes clear,
then proceed to connect the purifier to the machine.
- Connect the drain cup (G) to the drainage pipe (B)
- Should the mains pressure be higher than 5 bar a pressure
reducer balanced for high pressure should be installed
(device in which any mains pressure increase does not
effect the output pressure).
5.2 Electrical connection
Important ! Before proceeding with electrical
connection it is necessary to check to ensure that the
voltage rating corresponds with that indicated on
the CE plate and on the connection plate on the
power supply cable.
Check to ensure that the electrical supply line is able to support
the machine load (see chap. 4 – technical features table).
Connect to an earthing socket which complies with current
legislation.
Check that the power supply cable is efficient and that it
complies with national and European safety standards.
The user must undertake to power the machine protecting the
power line using a suitable safety switch (cut-out) that complies
with the legislation in force in the actual country itself.
Connect the power cable (1) to the electric line using a plug,
or in the case of fixed installation, using a multi-polar switch
(D) for mains separation, with a contact distance of at least 3
mm.
For voltage change refer to the diagram shown on the general
mains switch box.
The yellow-green coloured cable MUST be connected to the
room’s earthing system.
IMPORTANT
Before connecting to the water mains, assemble the one-
way valve (valvola di non ritorno), indicated in the dia-
gram, as follows:
Unscrew the nut, remove boiler filling valve pipe and insert
the one-way valve with the gasket towards the boiler valve
body. Reattach pipe, tighten the nut and connect to the
water mains.

6.1 Long coffee gigleur
The machine is fitted with a gigleur ( 1 per unit) with a
clearance of 0.6 mm (Cod. WGA26G0074/01).
For greater coffee delivery speed, in the case of long coffees,
no.2 gigleurs are also included with the machine (complete
with seals) with a clearance of 0.8 mm (Cod.
WGA26G0073/01). The gigleur is located in the
exchanger supply fitting (1 per group).
6 - START UP
Once the water, gas and electrical connections have been
made, proceed to start up the machine.
Open the mains water supply tap (A) (fig 2).
Close the protection switch (D) (fig 2).
Position the machine main switch (8) to position the
machine on indicator will come on (3).
The auto-levelling device will come into operation so that
the water reaches a normal level in the boiler (12).
Position the main switch (6) to position for operation at
normal power or to position for operation at full power,
thereby powering the resistances.
Wait for the pressure to reach its operational pressure
1.11.3 atm checking the boiler pressure on the gauge
(10).
Should the machine fail to stabilize on the indicated values
it is necessary to calibrate the pressure switch as described
in paragraph 6.2.
In the event of a machine featuring a gas heating system, it
is necessary to switch on the gas by operating the gas valve
(4) after operating the main switch (6), keeping the
piezoelectric switch pressed (5) until the gas remains on.
Then check the pressure on the pump gauge (10) putting a
unit into operation with filter holder engaged filled with
ground, dosed and pressed coffee in order to achieve an
effective working pressure of 8/9 atm.
Should re-calibration of the pump pressure be necessary
this operation should be undertaken as indicated in
paragraph 6.3.
The machine is now ready for use.

6.2 Pressure switch adjustment
The pressure switch shown in the figure acts to keep the
boiler pressure constant by engaging or de-activating the
electrical heating resistance.
This pressure switch is already calibrated to 1.1-1.3 bar
during the initial machine testing stage, but should a different
working pressure be required, it is possible to vary the
operational field of the pressure switch using the regulation
screw (U); pressure reduction results in a reduction in tempe-
rature, whilst increasing the pressure will also increase the
water temperature. The regulation direction is shown in the
figure and on the pressure switch itself. The pressure varies
by 0.1 atm for every complete screw turn.
Warning: Disconnect the electricity supply before
undertaking this operation.

6.3 Pump pressure calibration
Insert the filter holder into the unit filled with regularly ground,
dosed and pressed coffee.
Switch on the unit switch (AROMA SM) or the unit control
keyboard (AROMA SE) (16) and read the pressure on the
pump pressure gauge (10).
NB: The correct pressure is of 8-9 atm.
Should the pressure indicated on the pressure gauge be
incorrect, turn it clockwise to increase the pump pressure
and anti-clockwise to reduce the pressure.
Once adjustment is complete check pump calibration by
delivering one or more coffees.
Z= Pump pressure adjustment screw.
Warning !!
When the machine is new the filter-holder sump may
not be aligned (perpendicular to the machine itself)
as shown in the figure at the side, however this does
not effect the efficient function of the same.
After a short period of use the sump will gradually
settle into a correct position.

B = Position of closed filter holder with machine after a
short period of use.
6.4 Filters for coffee machine
Depending on the quantity of coffee ground, the appropriate
filter must be used as shown below to avoid that, once the
coffee has dripped out, the leftover powder remains attached
to the nozzle.
IMPORTANT: N°2 under-tile packings with are thinner
(8.1mm ) than that fitted as standard are included. These
packings may be used in the event of difficulty with inser-
tion of the filter holder.
