Filling 10. Filling with Bath Liquid The selection of the proper bath liquid (heat transfer liquid) influences the capacity of a temperature control unit deci- sively. The technical data with special emphasis on the tem- perature accuracy was established in accordance with DIN 58 966 (water at 70 C). - Page 20 Please get in contact with us should you have any questions. We are glad to advise you and can help you to choose a heat transfer liquid suitable for your application HAAKE heat transfer liquids are supplied with an EC Safety Data Sheet. ! Important ! HAAKE takes no responsibility for damages caused by the selection of an unsuitable bath liquid.

Filling 10.2 Filling with heat transfer liquid Filling level of the interior bath: max. up to 2.0 cm below the cover plate, min. up to 5.0 cm below the cover plate. External systems included within the circulating circuit have to be filled with the same heat transfer liquid in order to avoid too much liquid being drawn from the internal bath. -

Connecting Up 12. Connecting Up 230 V 12.1 Connecting to the mains Only attach this unit to mains sockets with a grounded earth. Compare the local mains voltage with the specifications writ- ten on the name plate. Voltage deviations of +/- 10% are per- missible. -
Page 24: Fuses On The Unit
Connecting Up 12.4 Fuses on the unit All units are equipped with automatic thermally-triggered fuses. If the fuse has triggered the fuse does not have to be exchanged – resetting suf- fices; a red marking is visible; a certain cooling down time should be allowed (approx. 5 min) before the (dip) switch can be pressed again. -
