8.4 Bath fluid
This circulator is only approved for use with water as the
bath fluid.
Recommended water mixture.
70 % soft/decalcified water and 30% tap water.
The parts of the bath which come into contact with the bath fluid may
be damaged and cause the failure of the device.
The water quality depends on the local conditions.
•Hard water is not suitable for temperature control tasks due to
its high lime content and will produce lime deposits in the bath.
•Ferrous water can cause corrosion, even on stainless steel.
•Chloric water can cause pitting corrosion.
•Distilled and deionized water is not suitable. Their specific
properties cause corrosion in the bath, even on stainless steel.
Check the quality of the water you use at regular intervals.
Evaporation and constant refilling may produce a concentration
of harmful substances in the bath.
You should therefore check the quality of the water in the bath
at regular intervals.
Replace the water in the bath in full at regular intervals.
