Caution:
Securely fix the immersion circulator. The heater may not be in contact with the wall of
the bath tank. Keep a distance of at least 15 mm.
Units not adequately fixed may drop into the bath tank.

First pull out the power plug to disconnect the unit from the power supply net. Then
take the immersion circulator out of the bath tank.
Make a service technician check the instrument before it is used again.
 Place the unit on an even surface on a pad made of non-
flammable material.
 The heating immersion circulator is mounted using a bath
attachment clamp (21) designed for bath wall thicknesses up
to 26 mm.

 Use the two sleeves (22) supplied with the unit to reduce the
immersion depth from 165 mm to 145 mm (see drawing).
 For use with glass vessels an upright stand rod, available as
optional accessory (order no. 8 970 022) may be attached.
5.2. Bath fluids
Caution:
Carefully read the safety data sheet of the bath fluid used, particularly with regard to
the fire point!
If a bath fluid with a fire point of
65 °C is used, only supervised operation is possible.
Water: The quality of water depends on local conditions.
 Due to the high concentration of lime, hard water is not suitable for temperature
control because it leads to calcification in the bath.
 Ferrous water can cause corrosion - even on stainless steel.
 Chloric water can cause pitting corrosion.
 Distilled and deionized water is unsuitable. Their special properties cause
corrosion in the bath, even in stainless steel.
