Safety recommendations
 Employ suitable connecting tubing.
 Make sure that the tubing is securely attached.
 Avoid sharp bends in the tubing, and maintain a sufficient distance from
surrounding walls.
 Regularly check the tubing for material defects (e.g. for cracks).
 Preventive maintenance: Replace the tubing from time to time.
5.4. Filling / draining
Notice:
 Pay attention to the thermal expansion of bath oil during heating to avoid
overflowing of the liquid.
 Do not drain the bath fluid while it is hot!
Recommendation: Temperature range 5 °C to 40 °C
Check the temperature of the bath fluid prior to draining (by switching the unit on
for a short moment, for example).
 Store and dispose the used bath fluid according to the laws for environmental
protection.

The circulator provides an early warning system for low level
(description – please refer to page 30) that may be triggered when
changing samples in the bath.
Draining:
 Turn off the unit and disconnect the mains cable from the power
source.
 Hold the venting grid, pull out and remove.
 Slide a short piece of tube onto the drain connection and hold it
into a container.
