5.4 Adjustment of temperature of dispenser groups: (models NEW 105)
In models NEW 105 (except for models NEW 105 DTC) the temperature can be adjusted for the serving of
espresso coffee without changing the internal pressure of the boiler. At the head of the serving group, there is
a valve (flow variator) that controls the flow of hot water coming from the exchangers. This valve is accessible
from the upper tub, by removing the plastic cup holding grille (figure 15). Four numbered notches are imprin-
ted on the upper tub (

,
3
,

,

) for each serving group (figure 16). The valve is normally set to number
3
(this
is the default setting provided by LA SAN MARCO SPA). If you want to change the serving temperature, you
will need to use the valve (flow variator) of the group. To increase the temperature, turn the valve towards the
higher numbers. Contrarily, to decrease, turn the knob towards lower numbers.
5.5 Adjustment of temperature of hot water (NEW 105 E)
Models NEW 105 E with 2/3/4 groups include a mixer that makes it possible to adjust the temperature of the
hot water for the preparation of infusions. The mixer can be calibrated by turning the adjustment screw, which
is accessed from the upper tub (figure 17). The mixer undergoes standard calibration by LA SAN MARCO
SPA. If you want to adjust the temperature of the hot water drawn, turn the screw clockwise. On the contrary,
to decrease the water temperature turn the screw counter-clockwise.
