 The unit is switched on.
 The rotary evaporator is operational and switched on at the power switch.
The rotation remains in the connecting solution between the con-
trol panel and the evaporator.
The Distillation rate (dT) can be increased by increasing the
speed.
The set target value is automatically assumed after 10 s.
1. Activate the rotation display with the aid of the selection window by using the rotary
pushbutton controller Hei-GUIDE (9).
2. Pressing the rotary pushbutton Hei-GUIDE (9) makes it possible to change the
value. The selection window flashes.
3. Turn the rotary pushbutton knob Hei-GUIDE (9) to set the display value to the de-
sired target speed.
The evaporator responds immediately, if the rotation has been switched on via the
Rotation start (8) pushbutton.
If timing has not been set, the time will be counted upward after pressing the Rota-
tion start (8) pushbutton. An arrow "up" will be inserted under the min display.
4. Switch on the rotation by pressing the Rotation start (8) pushbutton. The speed
display shows the actual value.
If the rotation has not started after 10 seconds of inactivity of the
Hei-GUIDE, the frame jumps to the Rotation parameter, the
target value and the frame will be displayed until the rotation is
started by the rotation pushbutton "start/stop
“.
The selection window is activated by the rotation speed at rotation
"off" and the target value of the rotation, the target value for "tim-
er" (if selected) and the actual values for "bath temp" and "vapor
temp" will be displayed.
A selection window will not be displayed at rotation "on", but only
the current values.
