5. Preparations
5.1. Installation
Caution:
Take care the temperature of cooling water in the loop circuit does never
exceed 40 °C.
The cooling capacity varies with the temperature difference between return
line and ambient temperature.
See technical specifications page 8
Parts of the unit may be destroyed by high cooling water temperatures. Hot
fluid may leak and result in severe skin burns.
 Place the recirculating cooler on an even and solid base.
 The unit should be set up in a frost-proof and dry location.
 Take care the mains switch is easily accessible.
 The ambient temperature must not exceed 40 °C.
Recommendation: approx. 20 °C
 A distance of at least 20 cm on the front and rear venting grids must be
maintained for ventilation, allowing internal heat to be conducted away
from the unit.
5.2. Bath fluids
Caution:
No liability for use of other bath liquids!
Please contact JULABO before using other than recommended bath fluids.
JULABO takes no responsibility for damages caused by the selection of an
unsuitable bath fluid
Do not use alcohols.
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.
Recommended bath fluids:

soft/decalcified water 5 °C to 80 °C
