5.5 Additional notes for models TOP 85 DTC (Dual Temperature Control)
The cooling system of the models TOP 85 DTC has the purpose of ensuring thermal stability of the water used for
serving espresso coffee. This system uses a special serving group in which the cold water from the mains passes
through a small tube located in a compensation chamber. The hot water from the heat exchanger of the boiler
passes through the serving group and comes into contact with the cooling tube. As a result it loses heat.
6. Operating instructions
During the flow of espresso coffee, tea or steam, these substances can cause burns due to ac-
cidental skin contact.
Each brewing unit has a pushbutton panel with five buttons (four for the programmed doses and one for
manual doses. While brewing, a luminous bar appears on the display that simulates the progress of the coffee
dose. The duration of brewing in seconds is always shown on the display.
Note:
Make sure that serving into the cup has taken place correctly. If serving has not occurred correctly, see the
chapter "PROBLEMS AND SOLUTIONS".
6.1 Serving of espresso coffee
1) Remove the filter-holding cup from the serving unit and fill it with a dose of ground coffee (filter cup with
one spout) or with two doses of ground coffee (filter cup with two spouts). Press the ground coffee using
the relative coffee presser and then insert the filter cup into the serving unit.
2) Place one or two cups under the serving spouts.
Brewing is always enabled and does not depend on the boiler temperature or the water level in the boiler,
except in the case of the maximum boiler level (brewing is not possible in this case).
