5.4 Temperature adjustment of dispensing units:
In the NeW 105 TOUCh models (except for the NeW 105 TOUCh DTC models), the espresso coffee dispens-
ing temperature 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 notch-
es are imprinted on the upper tray (2, 3, 4, 5) 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
temperature, 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 TOUCh DTC
(Dual Temperature Control) models
The cooling system of the NeW 105 TOUCh 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 exchanger of the boiler passes through the dispensing unit and comes into contact with the cooling
tube. As a result it loses heat.
