Control Of Water Temperature In The Boiler; Stabilizing The Brewing Temperature; Measuring The Brewing Pressure; Measuring The Water Supply Pressure - ELEKTRA Professional espresso coffee machines User Manual

8 CONTROL OF WATER TEMPERATURE IN THE BOILER (K-Kwts-S-M-C-B)
This keeps the temperature of the coffees constant as opposed to the temperature
and the pressure of the steam.
Consequently, it also controls the pressure in the boiler.
9 STABILIZING THE BREWING TEMPERATURE (K-Kwts-S-M-C-B)
Each dispensing group has a heating circuit for brewing water that functions with
a heat exchanger.
This circuit ensures that the dispensing group remains at a constant and optimal temperature
even when it is not being used thanks to the effect of the natural circulation of hot water
fl owing through the circuit itself.
10 MEASURING THE BREWING PRESSURE (K-S-M-C-B)
This enables the manual regulation of pump pressure during coffee dispensing.
The pressure is displayed on the gauge clearly visible in the working area.
On the K model, the gauge is fi tted inside the machine.
11 MEASURING THE BREWING PRESSURE (Kwts)
Through the reading of the display, this enables the manual regulation of pump pressure
during coffee dispensing.
12 MEASURING THE WATER SUPPLY PRESSURE (Kwts)
Enables automatic protection in the event of a water supply stoppage.
13 PROTECTION OF THE HEATING ELEMENTS (K-Kwts-S-M-C-B)
This consists of a safety level probe that triggers the cutting off of power to
the heating elements.
Resetting takes place through Basic Programming.
See chapter "G – USE".
14 PROTECTION FROM OVERHEATING (K-Kwts-S-M-C-B)
In each of following cases:
- Excessive duration of heating
- Exceeding of maximum allowable temperature value, the heating elements are disabled
and a major fault is reported.
15 UPPER CUP TRAY (S-M-C-B)
These models are equipped with cup heater trays with the capacity to contain a large
number of cups on various levels and to keep them warm in order to guarantee an excellent
cup of coffee.
The heat is generated by a natural fl ow of hot air from the inside of the machine.
