If the liquid levels in the circulator bath and the external
system are at different heights, overflowing must be
prevented after the power has been turned off.

Warning: Tubing:
At high working temperatures the tubing used for temperature application and cooling
water supply represents a danger source.
A damaged tubing line may cause hot bath fluid to be pumped out within a short time.
This may result in:
 Burning of skin
 Difficulties in breathing due to hot atmosphere
