Caution:

Always turn off the unit and disconnect the mains cable from the power source
before cleaning the unit.

Prevent humidity from entering into the circulator.

Electrical connections and any other work must be performed by qualified
personnel only.
Maintaining the cooling performance
In dusty environments, the cooling machine’s condenser should
be cleaned by vacuuming every 1 to 2 months. The condenser is
located behind the venting grid on the front of the unit, which can
be taken off by removing the screws.
 Switch off the unit, disconnect the mains power cable.
 Remove the venting grid.
 Clean the ribbed condenser with a vacuum cleaner.
 Replace the venting grid.
 Switch on the unit.
Cleaning:
For cleaning the bath tank and the immersed parts of the circulator, use low
surface tension water (e.g., soap suds).
Clean the outside of the unit using a wet cloth and low surface tension water.
The circulator is designed for continuous operation under normal conditions.
Periodic maintenance is not required.
The tank should be filled only with a bath fluid recommended by JULABO. To avoid
contamination, it is essential to change the bath fluid from time to time.
