Safety recommendations
 Employ suitable connecting tubing.

 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 or cold!
Check the temperature of the bath fluid prior to draining (by switching the unit on
for a short moment, for example).
 Store and dispose of the used bath fluid according to environmental protection
laws.
Filling
Make sure that no bath fluid enters the interior of the circulator during
filling.

Recommended maximum filling level with water as bath fluid:
30 mm below the tank rim

Recommended maximum filling level with bath oils:
40 mm below the tank rim

After filling, immerse the samples in the bath, or place the lid on
the bath if the opening is not to be used.

The ME circulator has an early warning system for low level that
may be triggered when changing samples in the bath.
Draining:
 The drain tap is located behind the venting grid on the front of
the unit, which can be taken off by removing 4 screws.
 Slide a short piece of tube onto the drain connection and hold it
into a container.

completely.
