7.4 Maintenance of the recirculating chiller: Replacing the cooling water
WARNING
Risk to health due to cooling water additives
The biocide used is corrosive and can cause an allergic reaction on skin contact.
¡ When handling the cooling water additive, wear protective glasses, clothing, and, in
particular, gloves.
¡ Observe all notes and specifications in the safety data sheet.
NOTICE
Risk of device damage due to corrosion and algae growth
Only the use of the cooling water additive can effectively prevent damage due to corro-
sion or biological contamination of the device.
Damage to the device caused by operation of the device without cooling water additive
is excluded from the warranty.
¡ Always add the cooling water additive (418-13-410-540) supplied by
Analytik Jena AG
to the cooling water.
The cooling water must be replaced at least once per year. The cooling water must al-
ways be replaced if the conductivity increases beyond 50 to 200 µS/cm
