3.2.- Preparation and start-up
This model is manufactured in 1, 2 or 3 group heads, and belongs to a standard gamma, professional,
trustworthy and of great performance and efficiency.
Before the technician turns on the machine, he must make sure that the socket has a proper ground and
that the water inlet pipe and drainage tube have been properly installed. Moreover, the water key must be open
to let water in when the machine starts running. The minimum Net pressure is 300 kPa (3 Bar).
Make sure all these preparations and parameters are correct. After this is done, the machine can be
plugged to power (1 Phase, 110V or 220/230V depending your case and 50/60Hz) and turned on by the
technician.
When turning on the machine, place the main switch to Position 1. This will permit the machine to start.
First thing the machine will do is checking the water level inside the boiler. As it is empty, the machine will start
filling the boiler. The Pos. 2 in the main switch makes same function as Pos.1.
If for any reason the boiler does not finish the filling process during 2 minutes, the buttons on the touch-
pads will blink. If this happens, place the main switch in Pos.0 and start the process again. In order to help the
machine filling the boiler, we can open the faucets/taps and press a button on a touchpad to activate the group.
This will release possible air accumulated inside the system. Just to know that the machine comes with a
electronic level control, so each time the machine detects a lack of water inside the boiler, it will automatically
activate the motor-pump and the filling solenoid to refill the boiler.
The machine has been equipped with a double probe system. One probe is to protect the heating
element (Security probe) and the other probe is to control the water level inside the boiler (Level probe). First
probe will allow the machine to heat the water when it arrives to that minimum level inside the boiler, and the
second probe will limit the filling of the boiler, avoiding the boiler from exceeding its water level. Otherwise there
would be not enough room for the steam.
Being the boiler filled, the element will keep heating the water during aprox 15 minutes until the steam
pressure inside the boiler is 100 kPa (1 Bar), and the temperature of the water reaches aprox the 100ºC (212ºF).
Now it will be only the pressure-stat the one to run the machine. It will control when the element must
turn on and off to heat the water inside the boiler and generate enough steam pressure. So now the machine is
ready to start making coffees and getting hot water for tee or steam to froth the milk, shakes, etc.
Once on a while make sure all the parameters are correct: water net pressure must be minimum 300
kPa (3 Bar), boiler pressure 100 kPa (1 Bar) and pump pressure 900 kPa (9 Bar).
If some of these parameters are not correct, please let the technician know so he can adjust them again.
Never open the machine and try to adjust or modify these parameters for yourself!!!
3.3.- Preparation and coffee brewing
When all is ready to work, we recommend to play with the machine. It means taking some water from the
groups by pushing on a touchpad button (or the push-button if the machine is semi automatic), as well as getting
out some steam and hot water. This will warm the group heads and the wands and so the machine will be ready
to make coffees.
When pressing a button from a touch pad, the corresponding green/blue Led will blink showing that the
brewing process is working properly.
