6.4 Setting the heating bath temperature (Actual value dis-
plays of all modes)
The heating bath is filled with heat transfer liquid.
The rotary evaporator is operational and switched on at the power switch of the
base unit (Figure 5-1 (1)).
WARNING Hot surfaces during the operation of the heating bath!
Burns.
Do not touch the interior and the upper edge of the heating
bath, the evaporator flask and the heating bath liquid.
Wear suitable heat protection gloves when changing the
evaporator flask.
CAUTION Overheated heating bath!
Property damage and visual changes of the heating bath.
Never operate the heating bath without liquid.
The range can be set from 20 - max. temperature of the heating
bath [°C] in 0.5 [°C] increments. 20 C [°C] are set as default when
shipping from the factory.
Only use suitable oil as heat carrier for target temperatures above
100 °C (observe safety data sheets, refer to chapter 11.3 and
chapter 4.4.2).
1. Switch on the heating bath by pressing the pushbutton heating bath on/off (3).
The illuminated yellow control ring of pushbutton heating bath on/off (3) shows that
the heating bath is activated. An icon [heat waves] in the display shows that the bath
is in the heating phase (current flows into the heating coils of the bath).
2. Select the entry "heating bath" by turning the Hei-GUIDE (6) and call up the se-
lected entry to be changed by pressing the Hei-GUIDE (6) again.
3. Pressing it again confirms the change.
6.5 Calculating the vapor temperature (with an optional va-
por temperature sensor)
If a vapor temperature sensor is connected during the operation:
Switch the unit off and on to activate the program part.
The vapor temperature is displayed on the screen of the control panel when the vapor
temperature sensor is connected.

6.6 Process modes

The Hei-VAP Precision forms a unit with the control panel, the vacuum box and the va-
cuum valve, in which the vacuum is controlled by opening and closing a valve. The va-
cuum valve is not required when using a speed-controlled pump.
The ventilation valve in the vacuum box is always open when the
vacuum control is switched off.
