6.3 Filling and draining
Filling
 
Close the drain cock!

Carefully remove all residues of the previous heat transfer liquid (blow dry and re-
move 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
WX103
(

Section 7.14.4).

Best operation is with a level 20
– 80 mm below the top edge of the bath.

Low-level cut-off occurs at about 95 mm (at P 12 C approx. 215 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 (

Section 6.4) may only be
used below the flash point.

When using thermal transfer oils note that they expand on heating (approx. 10 % per
100 K).

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 im-
permissibly due to filling the load. Top up with heat transfer liquid if necessary.

Set the upper and lower temperature limits (

7.8.3) in accordance with the limits of
the heat transfer liquid in use.
Draining

Switch off the thermostat, withdraw the mains plug!

Let out the heat transfer liquid through the drain cock;
fit a hose when doing this.

The drain cock is placed on the back of the heating
thermostats.
Completely drain the bath, external consumers, accessories and hose connections and flush or clean
them (e.g. with new heat transfer liquid).


Follow the regulations for the disposal of used heat transfer liquid.
Do not drain heat transfer liquid when it is hot or at bath temperatures below
0 °C!
