6.2 Filling and draining
Filling
− Close the drain cock.
− Carefully remove all residues of the previous
heat carrier 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
VW@pl0/2
(Ì Section 7.14.4).
− Best operation is with a level 20-80 mm below
the top edge of the bath.
− The cooling pipe of the evaporator should be
covered. Depending on the operation up to
three pipe windings might be uncovered.
− 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 liquids must not be used higher than 25°C below the
fire point (Ì Section 6.3).
−
When using heat carrie
r oils note that they expand on heating (approx. 8%/ 100°C).
− With enclosed external loads, the overall expansion takes place in the bath.
− Ensure that with the connection of an external load, the liquid level does not drop
impermissibly due to filling the load Æ top up with liquid if necessary.
− Set the upper and lower temperature limits (Ì 7.8.3) in accordance with the limits of the

Draining
− Switch off the thermostat withdraw the mains plug.
− Let out the heat carrier liquid through the drain cock; fit
a hose when doing this.
− On thermostats, the drain cock is located behind the
front panel.
− Follow the regulations for the disposal of used heat carrier liquid.
Do not drain heat carrier liquid when hot or at bath temperatures below 0°C!
