hose clamps.

6 .2 .2 Filling the chiller
NOTICE
Risk of instrument damage if wrong cooling medium is used.
• Check to ensure that the cooling medium is suitable for use at the desired cooling tempera-
ture and does not freeze at the working temperature
Fill the cooling liquid in the opening to maximum filling level while the chiller is not connected to
another device. We recommend a mixture of ethylene glycol/water at least 40/60, which does not
freeze until -16 °C.
