5.2 CARTRIDGE EXCHANGER SYSTEM<br />
5.3 EXTRACTABLE EXCHANGER SYSTEM<br />
espresso coffee machine - instructions for technician<br />
Heating of the delivery group is provided by direct contact with the boiler. Water used for delivery of coffee is taken from a so-called “cartridge”<br />
exchanger which is immersed in the water of the boiler.<br />
• the activation of the solenoid valve and of the pump allow cold water to enter the exchanger (1).<br />
• From the exchanger (1) the boiler water is carried to the group duct (2) for delivery.<br />
• the pump allows the increase of the pressure of the water flow up to 8-9 bar.<br />
If necessary, the exchanger can be replaced by removing the flange and disconnecting the relative pipes of the hydraulic circuit. These operations<br />
should be carried out after the machine has been switched down and has cooled off. Always replace the seals.<br />

<strong>Coffee</strong> delivery<br />
Heating of the delivery group is provided by direct contact with the boiler. Water used for delivery of coffee is taken from a so-called “extractable”<br />
exchanger which is immersed in the water of the boiler.<br />
• the activation of the solenoid valve and of the pump allow cold water to enter the exchanger (1).<br />
• From the exchanger (1) the boiler water is carried to the group duct (2) for delivery.<br />
• the pump allows the increase of the pressure of the water flow up to 8-9 bar.<br />
The version of the extractable exchanger for the Italian market does not include the suction device (3) and the seal (4).<br />
If necessary, the exchanger can be replaced without having to remove the flange. Loosen the screws, remove the delivery group from the<br />
boiler and remove the exchanger. These operations should be carried out after the machine has been switched down and has cooled off.<br />
Always replace the seals.<br />
