Service
 Turn the Rotating/ Pressing knob to the right/left to select a menu
option.
 Press the Rotating/ Pressing knob.
 Turn the Rotating/ Pressing knob to change the value (the magnitude
of the change is dependent on the speed at which the knob is turned).
 Press the Rotating/ Pressing knob again to complete the process.
ESC key: Exit menu, all changes to switch settings are reset, the calibra-
tion remains unaffected.
Switching valves and pump
To check functionality for servicing purposes, use the Service menu to
activate/deactivate directly the valves included in delivery or optional and
the pump, e.g. RV 10.5001.
The RV 10.5001 valve switches the water circuit on and off. This row also
shows the current cooling water flow rate.
Calibrate
The "Calibrate" option is used for calibration of the temperature sensor.
The temperature difference displayed will be calibrated to zero. This ac-
tion cannot be reversed.
The temperature sensor must be calibrated whenever it is replaced or
changed, or if a new temperature sensor is installed.
Please contact the Service department.
The temperature sensor supplied with the system is calibrated ex-works.
Performing calibration
 Activate the "Calibrate" menu option by turning the Rotating/ Pressing
knob.
 Remove both sensors. To remove a sensor, push back the outer ring to
release the locking device on the push-in connector, while at the same
time pulling the temperature sensor out of the connector, see fig. 26.
 To reconnect a temperature sensor, push it into the push-in connector
until the limit stop is reached; an initial resistance will be felt.
 Fill water at room ambient temperature into a glass beaker (approx.
 Wait until the temperature display in the "Service" menu, menu option
 Press the Rotating/ Pressing knob.
 The temperature difference displayed will be calibrated to zero.
Calibration is only possible within the temperature range +0.5 K to -0.5
K. If the temperature is outside this range, then either a temperature
sensor is faulty or connected incorrectly. Please contact the Service de-
partment.
If the characteristics of the cooling water supply deviate significantly
from the specifications given in the "Technical specifications", with the
result that the initial conditions for automatic distillation are not achie-
ved, then it may be necessary to recalibrate the temperature sensors.
This may, however, lead to a reduction in the accuracy with which the
distillate quantity is measured in "Auto-distillation" mode.
Operation hours
This value serves as informaton and cannot be changed.
