INSTALLATION AND START UP

Pressure and temperature

Boiler temperature and pressure are directly related (see Fig. 01).

Machine is tted with a pressure gauge that will display the boiler pressure, if the machine is tted with a

display it will also indicate boiler temperature.

Relationship between boiler pressure and temperature

Water connection

The Installation of the machine to a water mains connection must be done by a qualied person.

Rinse around 20 liters of water from the main water supply before connecting the machine to the water connection.

Connect the inlet hose that is assembled in the machine to the main water supply, which should have a

3/8” male connection tted with a shut-off valve, tighten it with a wrench.

Use safe drinking water with hardness between 5ºfH and 8ºfH (French hardness degrees). If the value is

below this limit, the presence of corrosion of hydraulic components is a possibility. If the value is higher

than this limit, the presence of lime in the boiler will increase. In both cases the operation of the machine

and coffee quality will be affected negatively.

If necessary, connect the machine to a water softener or remineraliser to reduce water hardness. Use the

exible hose that is included in the accessory box of the machine.

Connect one end of the corrugated tube to the drain cup in the machine, connect the other to the main

drainage tube at the installation area.

Important:

Only use the hoses supplied with the machine. Never reuse hoses.

Make sure that the drainage tube is not twisted and ensure that the entire tube is below the

level of the drain cup.

Starting the machine

Open the external supply of water to the machine.

Turn on the main power switch.

Press a drink button at the control panel on each group, wait until

water comes out continuously from each of them. This way the

heat exchangers in the machine will be correctly lled.

Open the steam tap to release the air trapped in the boiler.

The red lamp indicates that the boiler is heating. The lamp

switches off when the machine reaches operating temperature.

The machine is now ready to use.
