5.4 Temperature adjustment of dispensing units:
In the NEW 105 T models (except for the NEW 105 T DTC models), the espresso coffee dispensing tempera-
ture can be adjusted without changing the internal pressure of the boiler. A valve (flow variator) is fitted to the
tip of the dispensing unit, which controls the flow of hot water from the exchangers; this valve is accessible
from the upper tray, after removing the plastic cup support grille (figure 15). Four numbered notches are im-
printed on the upper tray (

) for each dispensing unit (figure 16). The valve is normally set to number
3
(this is the default setting factory set by lA SAN MARCO SPA). If you wish to change the dispensing tempera-
ture, you will need to use the valve (flow variator) on the dispensing unit. To increase the temperature, turn the
valve towards the higher numbers. Contrarily, to decrease it, turn the knob towards lower numbers.
5.5 Additional notes for NEW 105 DTC (Dual Temperature Control) models
The cooling system of the NEW 105 DTC models has the purpose of ensuring thermal stability of the water
used for dispensing espresso coffee. This system uses a special dispensing unit in which the cold water from
the mains passes through a small tube located in a compensation chamber. The hot water from the heat ex-
changer of the boiler passes through the dispensing unit and comes into contact with the cooling tube. As a
result it loses heat.
