7. 7 H OT AN D CO LD WAT ER
VALV E
The E1 PRIMA is provided with a cold water
valve with adjustable mixer.
In this way the outlet water temperature
can be lowered by mixing hot water from
the boiler with cold water from the network,
thus reducing the levy in the boiler and
consequently saving on heating.
For this reason it is commonly called econ-
omizer of hot water.
HOW TO ADJUST THE TEMPERATURE
To adjust the temperature, simply use a flat
screwdriver while the water is running.
To reduce the temperature, rotate the screw
positioned on the left side of the cup holder
surface in an counter-clockwise direction.
To increase the temperature, turn the screw
in a clockwise direction.
NOTE
Do not reduce the temperature too much,
otherwise the valve could emit an annoy-
ing noise.
WHEN TO INTERVENE
Problems that can be encountered in the
economizing unit are:
1 Failure to deliver water.
2 Delivers only hot or only cold water.
3 Continuous dripping.
4 Erroneous programming.
Cases 1, 2 and 3 are due to malfunction of
the valves so you need to access them and
verify that they are working properly.
The valve may stop operating due to elec-
trical problems or is not working properly
due to obstructions for example caused by
pieces of limestone that detach from the
boiler and clog the valve.
If both valves do not work and the classic
opening and closing noise is not heard,
there could be a problem with the relay in
the control unit, therefore it is necessary to
directly measure the voltage with a tester
while water is being dispensed.
