6.3 Filling and draining
Filling


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 dis-
play 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 impermissibly
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 thermo-
stats.
1 Drain cock
2 Drain Nozzle
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!
