Follow the safety recommendations to prevent damage to persons or
property. Further, the valid safety instructions for working places must be
followed.
• Only connect the unit to a power socket with earthing contact (PE –
protective earth)!
• The power supply plug serves as safe disconnecting device from the
line and must be always freely accessible.
• Operation is permitted with non-flammable liquids only.
• Place the instrument on an even surface on a pad made of non-
inflammable material.
• Do not stay in the area below the unit.
• Make sure you read and understand all instructions and safety
precautions listed in this manual before installing or operating your
unit.
• Never operate the unit without bath fluid in the bath.
• Check the filling level of the bath fluid from time to time. Pump and
heater must always be fully covered with the bath fluid!
• The instrument is not suited for unsupervised continuous operation.
• Do not drain the bath fluid while it is hot!
Check the temperature of the bath fluid prior to draining (by switching
the unit on for a short moment for example).

• Always turn off the unit and disconnect the mains cable from the
power source before performing any service or maintenance
procedures, or before moving the unit.

extremely warm during continuous operation. Therefore, exercise
particular caution when touching these parts.
