If these parameters are not met in mains water, a specific filtration device must be

installed, always complying with current national and local regulations regarding

drinking water.

Once the water inlet and drain connections have been made, we will open the valve or

tap to fill the boiler.

ATTENTION!

This equipment is to be installed with adequate backflow protection to comply

with applicable federal, state or local codes.

8 - Start-up

Set the main switch to the "ON" position (I) 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.

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 models ONE/PLUS) in order to start making coffee, and until the

temperature of the steam/hot water boiler reaches the set-pint one (the pressure gauge
