The inner components of the temperature control unit must be dried out Need to avoid boiling
retardation during future uses (e.g. use of a silicone oil at temperatures above about 100 °C).
7.4.3.1 Rinsing a thermal fluid circuit with >Sight glass< [23]
PROCEDURE

Drain the temperature control unit. → Page 61, section
»Draining with >Sight glass< [23]«
.
Residual thermal fluid can remain in the pump chamber and the internal lines after draining. Leave
the temperature control unit with open valves for a while.

Check the fill level in the collecting container. Follow the instructions for the proper disposal of
thermal fluid. → Page 15, section
»Proper disposal of resources and consumables«
.

Re-fit the knurled screw to the
>Residues drain<
[10] (if present).

Re-fit the knurled screw to the
>Drain<
[8].
Leave your externally open application connected to the temperature control unit. This rinses the
temperature control unit and your application at the same time.

Fill
the system (minimum fill level) with the thermal fluid you wish to use. → Page 59, section
»Filling and venting with >Sight glass< [23]«
.

Vent
the system. → Page 59, section
»Filling and venting with >Sight glass< [23]«
.

Adjust the
setpoint
and the cut-out value of the
overtemperature protection
to the thermal
fluid used. → Page 57, section
»Setting the setpoint«
and → Page 45, section
»Setting the over-
temperature protection«
.

Go to the “Categories Menu”.

Tap on the category “Temperature Control”.

Tap on the category “Start/Stop”.

Tap on the dialog entry “Start temperature control”.

Touch “OK” to confirm your selection. The length of rinsing depends on the level of soiling.

Tap on the category “Start/Stop”.

Tap on the dialog entry “Stop temperature control”.

Touch “OK” to confirm your selection. The temperature control process is stopped.

Drain
the system. → Page 61, section
»Draining with >Sight glass< [23]«
.

Repeat the steps “Filling”, “Venting”, “Start/Stop temperature control” and “Draining” until the
drained thermal fluid remains clear.

Leave the
>Drain<
[8] and
>Residues drain<
[10] (if any) open for a while to allow the thermal
fluid to evaporate in the temperature control unit.

Close the
>Drain<
[8] and
>Residues drain<
[10] (if any) once the thermal fluid has evaporated.

Remove the collecting container. Follow the instructions for the proper disposal. → Page 15,
section
»Proper disposal of resources and consumables«
.

Fill the system. → Page 59, section
»Filling and venting with >Sight glass< [23]«
.

Vent the system. → Page 59, section
»Filling and venting with >Sight glass< [23]«
.

Restart the temperature control unit in normal mode.
7.4.3.2 Rinsing the thermal fluid circuit with >Level indicator and drain< [38]
PROCEDURE

Drain the temperature control unit. → Page 62, section »Draining with >Level indicator and
drain< [38]« .
Residual thermal fluid can remain in the pump chamber and in the internal lines after draining.
Therefore leave the temperature control unit open for a while.

Check the fill level in the collecting container. Follow the instructions for the proper disposal of
thermal fluid. → Page 15, section »Proper disposal of resources and consumables« .

Reinsert the hose into the >Level indicator and drain< [38].
Leave your externally open application connected to the temperature control unit. This rinses the
temperature control unit and your application at the same time.
