7 – Hydraulic connection
First, we will connect the free end of the drain pipe supplied with the machine to the
previously installed general drain outlet.
In connection with the general network, a tap must be incorporated to interrupt the
flow of water to the appliance when necessary. Next, we will connect the flexible hose
(connection 3/8 "H) to the pump and to the water inlet of the network. In case a water
treatment system is installed, we will connect the hose to the outlet of said system.
IMPORTANT: Do not feed the coffee machine with water below 10º Fr hardness.
Once the water inlet and drain connections have been made, we will open the valve or
tap to fill the boiler.
8 – Start-up
Set the main switch to the "ON" position and automatically the machine will proceed to
fill the boiler to the set level. Once the filling process has been completed, the water will
be heated up to the working temperature and pressure.
Pump pressure regulation: The pump is factory-set to 9 bar pressure. If it is
necessary to adjust it, proceed as follows: Remove the plastic cap located on the side
panel of the machine, and with the help of a screwdriver, turn the screw of the pump.
In a clockwise direction, the pressure is increased. Counter clockwise decreases the
pressure.
Expansion valve regulation: The expansion valve is a component that limits the
maximum working pressure of the machine. This pressure must never exceed 12 bar.
The valve is regulated at 11 bar in the factory. If you wish to regulate the valve, follow
these instructions: Place the filter holder with the blind filter in the coffee group. Start
the unit and adjust the pump to the pressure at which you want to regulate the valve,
and then turn the regulator of the valve until the water comes out through it. Once the
process is finished, re-regulate the pump up to 9 bars.
ATTENTION!
The expansion valve can discharge very hot water (93º C / 200º F).
From this moment, it will be necessary to wait until the temperature of the coffee
groups reaches the set-point (showed in the specific display of each group dedicated
to the temperature) in order to start making coffee, and until the temperature of the
