Functional Description
The coffee roaster GEMMA is a machine composed of a body con-
nected to an electrical operating and control systems. The coffee is
loaded manually into the charge tank (K). The operator selects on the
display touch screen one program and start the toasting cycle.
Thanks to the presence of two electric resistances heat is introduced
into the roasting chamber. The roasting chamber is in continuous rota-
tion, thanks to the presence of an electric motor with gearbox and al-
lows to mix the coffee during the cycle. The rotation is visible through
the tree of the roasting chamber that protrudes from the front of the
machine (1 - Fig 7). When the machine makes the rst beep means it
has reached the programmed temperature drop coffee. The operator

STORAGE
The storage of the machines must be packed in protected from weath-
er and sun.
The storage time should be minimized (EEC or neighboring countries).
For more information on delivery times and storage requirements,
please contact customer service.
INSTALLATION
Attention
The packing must be disposed of according to law in the
country of installation.
Place the machine on a stable and level appropriate to support the
weight of the machine. Choose a well-lit, clean and with easily acces-
sible power outlet.
Do not place the machine on hot surfaces or near open ames to
prevent the body can be damaged.
Leave at least 200 mm between the machine and walls so as to allow
ventilation of the cooling fans.
Rotate the support feet (P) so as to stabilize and level the machine.
Attention
Danger of overheating. Do not place the machine attached
to walls, both laterally and in the rear.
Allow clearance from objects the work of the machine.
The electrical panel must be wall mounted using screw anchors suit-
able for supporting the weight of the picture.
Attention
Do not install the electrical panel near a heat source.
The maximum distance from the framework of the machine
should not exceed 1000 mm.
Leave space between objects by clearing the machine and the
framework in order to easily reach the disconnect electricity.
Connect the electrical panel to the machine (Fig. 2). The connection
cable can be inserted only one way. Do not use excessive force: when
trying to turn the connection of 180°.
Fig. 2
Place the power cable and the connection between the electrical
panel and the machine so that they are not a hindrance to the
normal working operations: it is preferable that both are lying at
on the ground in order to avoid the danger of tripping.
Check that the power cord and connecting cable between electrical
panel and the machine does not remain at odds with surfaces or sharp
edges.
Wash and dry the basket and the rst tank to use with cool tap water.
Enter the header tank into place (Fig. 3).
Fig. 3
Place the basket into place (Fig. 4).

English
Install the machine on the tailpipe fumes (H). The conduit must be
positioned laterally (Fig. 5) in order not to hinder the maneuverability
of the handwheel manual eject the coffee (J).
Fig. 5
Connecting ue
The machine must be installed with a special ue gas system.
You can use the pipe already in place to install the machine or you can
request a scavenging system (Optional).
The connection with an existing pipeline must include a ange for con-
necting the exhaust pipe of the machine with a diameter of 100 mm.
Use a hose resistant to high temperatures and non-ammable diam-
eter of 100 mm. Use a metal clamp to stop the tube on the exhaust
pipe of the machine.Connect the other end of the tube to the ange on
the scavenging system of the installation room. Use a metal clamp to
stop the pipe ange.
The smoke evacuation system (optional) includes an intake system
consisting of a hood and an engine intake.
Mount the engine intake to a minimum distance of 3 m from the
exhaust fumes.The suction motor must ensure an aspiration of
350 m3 / h.
The preparation and installation of smoke evacuation systems shall
be borne by the customer and must be in compliance with applicable
environmental laws on emissions in the country to use the machine.
The installation must be performed by a qualied professional.
COMMISSIONING
It is installed by the user on the supply line of the machine
a protective device (circuit breaker) that is automatically ac-
tivated in case of failure or overcurrent. Follow the instruc-
tions laws in the country of installation.
Warning!
Danger of electric shock. Connect the machine to an outlet
with grounding.
Before connecting the machine to check that the mains volt-
age indicated on the label on the back of the machine cor-
responds to the local system.
Try to open and close the slider located under the cargo tank of raw
coffee (Fig. 6).
Fig. 6
Check the ue pipe connection with the evacuation line in the local
installazione.Controllare the connection of the electrical power pole
with the machine.
Check that the voltage of the industrial network is equal to the one
shown on technical data.
Insert the plug into the electrical outlet, which must be equipped with
grounding.
Security systems
The machine is provided with a switch (B) that can be used as emer-
gency switch: turn the power switch to “OFF” to turn off the machine.
On the panel there is an emergency button (C). Press the emergency
button to stop the electric resistance and start the cooling cycle. Af-
ter the cooling cycle reset the emergency button: rotate and pull the
emergency button.
Alternatively you can grab the plug and unplug the power cord from
the outlet. The PLC maintains the electrical resistances and switches
off in the case of an excessive rise in temperature, thus avoiding the
danger that the coffee to enter in combustion.
When the machine is on the red lights on the buzzer to indicate that
the machine is running. When the machine has reached the tempera-
ture of the load and end-of-coffee roasting machine emits a warning
beep.
Checking the efciency of securities
Turn on the machine and check for proper operation of the switch (B)
and emergency push button (C). At the rst operation of roasting in the
applicant’s work shift, the efciency of acoustic signals. Check opera-
tion of red light located on the beeper sounds. Check the operation of
the engine rotation of the chamber of roasting: check the rotation of
the roasting chamber (1) Figure 7.
INSTRUCTIONS FOR USE
Warning!
Check at the beginning of each shift the efciency of safety
devices installed on the machine.
Do not leave the machine unattended during the toasting
cycle.
Always check that the shaft of the roasting chamber (1), Fig
7, which protrudes from the front of the machine is always
in rotation. The case is still off the machine immediately and
contact the Service Centre.

rise, visible in the eld TEMPERATURE, below PROGRAM. When the
temperature reaches 160°, the machine emits the rst beep: means
that is ready for the loading of the coffee in the tank. Gradually open
the slide (Fig. 6) and dropping in the coffee roasting chamber. Close
the slide.
Close the slide after loading the coffee machine.
The temperature begins to drop until it stabilizes and then up again
to the value stored in the program (shown in SET POINT, below SET-
TING PROGRAM). The temperature is maintained constant at the
temperature of the program for about 5 minutes. When the electric
resistances turn off, the automatic pre-cooling start: the fresh air is
blown into the roasting chamber.
When the temperature drops below 100 °C the machine will make an-
other beep to indicate that coffee can be downloaded to your basket.
Wait a few seconds until it stops fan inside the roaster and then open.
Every 4-5 cycles of roasting is necessary to remove and empty
the collection of lms (see Maintenance section).
Raise the lever (M) and lower the coffee basket (Fig. 12).

in such a way that any hot air coming out from the roasting
chamber does not invest the operator.

Changing a program in progress
If we realize that we have set the wrong program, and we have al-
ready started the toasting cycle, do the following:
- From the page of the program, press the STOP.
- Press the HOME key to access to the Home page.
- Press key of the new programma.
- Check the data set into the program and press the START button.
If we start the new cycle and the temperature in the total height
is higher than the temperature of the load coffee machine emits a
long beep. The new cycle has to be started when the temperature
in the roasting chamber is lower than the temperature of the load
coffee.
