Caution!
Use of unsuitable heat transfer liquid
Explosion, burns, scalds, fire

When selecting the heat transfer liquid, observe the
admissible temperature range.

Only use LAUDA heat transfer liquids.
Notice
Overfilling containers, spilling heat transfer liquid
Environmental hazard from leaking heat transfer liquid

Note the thermal volume expansion of the heat transfer
liquid.

Where necessary, consider the displacement volume of the
body being introduced.

Take the volume of external consumers into account.


Close the drain cock.

Carefully remove all residues of the previous heat
transfer liquid (blow dry and remove screw plugs!).

Maximum filling level is up to 10 mm below the top
edge of the bath. Overfilling leads to the display of
the warning
WXArn103
(

7.12.4).
Changes in volume of the heat transfer liquid during
temperature changes should be taken into account.

Best operation is with a level 30-80 mm below the
top edge of the bath.
 The cooling pipe of the evaporator should be
covered.

Low-level cut-off occurs at about 95 mm below the
top edge of the bath.


The units are designed for use with non-flammable and flammable liquids to DIN EN 61010-2-
010. Flammable heat transfer liquids may only be used below the flash point. (

6.3).
 When using heat transfer oils note that they expand on heating (approx. 10 %/100 K). With
enclosed external loads, the overall expansion takes place in the bath of the Proline Kryomat.

Ensure that with the connection of an external load, the liquid level does not drop impermissibly due
to filling the load

top up with liquid if necessary.

Set the upper and lower temperature limits (

7.6.2) in accordance with the limits of the heat
transfer liquid in use.
