Adjustment Of Temperature Of Dispenser Groups: (Models 100); Additional Notes For Models 100 Dtc Touch (Dual Temperature Control); Adjustment Of Temperature Of Hot Water (100 Touch) - SM 100 Touch Serie Bedienungs- Und Wartungsanleitung

5.4 Adjustment of temperature of dispenser groups
In models 100 tOUCh (except for models 100 DtC tOUCh) 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 acces-
sible from the upper tub, by removing the plastic cup support grille (figure 15). four numbered notches are
imprinted on the upper tub (2, 3, 4, 5) 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 Additional notes for models 100 DtC tOUCh (Dual temperature Control)

the cooling system of the models 100 DtC tOUCh 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.
5.6 Adjustment of temperature of hot water
100 tOUCh models with with 2/3/4 groups include a mixer that makes it possible to adjust the tempera-
ture 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.
Note:
The mixer must be adjusted with the coffee machine running in normal operating conditions. The steam pres-
sure in the machine is 1.0 bar (standard value set by LA SAN MARCO SPA). If the steam pressure in the boiler
is modified (as described in the related paragraph), the mixer must be calibrated again.
