10. Operating and Monitoring Systems 10.
1 Sight-glass, still:
For observing the distillation process .
16 Overfill sensor, safety separator: if
overfilling, diagnostic message appears.
2 Sight-glass, safety separator:
For observing the process water and checking
the safety separator.
17 Sensor, low level:
Regulates the detergent solution level.
3 Sight-glass, inlet to water separator:
For observing the condensate feed from
distillation.
18 Sensor, high level:
Regulates the detergent solution level.
4 Sight-glass, refrigeration unit:
For checking whether the cooling agent is free
of bubbles during the reduction phase
19 Overfill sensor, distillation:
Stops the pumping process when the
filling amount has been reached.
5 Cooling water regulator, refrigeration unit:
You can set the condensation pressure in the
refrigeration unit here.

22
Limit switches:
All maintenance openings are protected
with limit switches
6 Cooling water regulator, distillation:
Regulates the cooling water flow (setting of the
cooling water temperature at drain
approximately +45 °C/113 °F)
23 Sight-glass, water separator:
Visual inspection of solvent condition
7 Low cooling water level switch
Monitors the cooling water supply.
Set to 1 bar (14.5 psi).
8 Low pressure gauge (refrigerating)
For checking the evaporation pressure
9 High pressure gauge (refrigerating)
For checking the condensation pressure.
10 Pressure relief valve, machine (0.3 bar/4.4 psi):
Opens when the permissible operating
pressure is exceeded.
11 High pressure control (refrigerating): switches
the system to the malfunction state if there is
overpressure
Low pressure control (refrigerating): switches
the system to the malfunction state if there is
not enough cooling agent
12 Thermal sensor, aftercooler:
Monitors the aftercooler temperature and
switches the machine off when the temperature
exceeds 40° C (104 ° F)
13 Thermal sensor, cage housing outlet:
Monitors the temperature at the air outlet
14 Thermal sensor, solvent:
Monitors the solvent temperature.
31 Low air pressure switch:
Monitors the compressed air supply. Set
to 4 bar (58.0 psi).
15 Drying time controller:
Extends the drying time, depending on the type
and amount of garments
32 Pressure gauge, compressed air:
You can read off the required operating
pressure (6 bar/87.0 psi) on the pressure
gauge
