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.
•
Loosen the drain screw a few turns and drain the unit
completely.
•
Tighten the drain tap.
