7.4 Fill device
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 device 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 device 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 fill level and, if necessary, adjust it 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 refrigeration unit.
5. Close the bath opening with the bath lid.
The device is filled with bath fluid.
7.5 Set up power supply for the refrigerated circulator
For a refrigerated circulator, the power supply is configured at the factory. The
circulator is supplied with power from the refrigeration unit via a mains
extension cable. Alternatively, both devices can be connected to separate
circuits with one power cable each. The type of power supply is set in the
operating menu.
The cooling machine is connected.
