This section describes how the device should be filled with bath fluid during
initial operation.
Specifications for filling volume can be found in the technical data.
The drain valve is closed.
The unit is switched off.
1. Remove the bath lid.
2. Half fill the bath with bath fluid.
The bath fluid expands with increasing temperature and can overflow.
With decreasing temperature, the low liquid level protection can be
triggered and interrupt the temperature control process.
3. Switch the unit on and start the temperature control application.
If an external system is connected, the pump supply must be set to
“external” so that it fills the external system.
4. Watch the level indicator and, if necessary, adjust the level by refilling or
draining.
Once the working temperature has been reached and the sample inserted,
the level of bath fluid in the bath tank should cover the heating coil of the
heating circulator or the cooling coil of the cooling machine.
5. Close the bath opening with the bath lid.
The unit is filled with bath fluid.
