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).
PROCEDURE

Drain the temperature control unit. → Page 37, section
»Draining externally closed applica-
tions«
.
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.

Leave the drain hose mounted to the
>Drain<
[8].

Check the fill level in the collecting container at the other end of the drain hose. Follow the in-
structions for the proper disposal of thermal fluid. → Page 15, section
»Proper disposal of re-
sources and consumables«
.

Close the drain valves on the temperature c ontrol unit by turning them clockwise (turn 90° right
as far as they will go).

Connect the
>Circulation flow<
[1] with the
>Circulation return<
[2] at the temperature control
using a bypass hose.
Perform the following steps without attaching a short circuit hose, if the application used by you
(externally closed) is also dirty. In this case, leave your externally closed 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 36, section
»Filling and venting externally closed application«
.

Vent
the system. → Page 36, section
»Filling and venting externally closed application«
.

Adjust the
setpoint
to the thermal fluid used. → Page 33, section
»Set/change setpoint«
.

Start
the
circulation
. The length of rinsing depends on the level of soiling.

Stop
the
circulation
.

Drain
the temperature control unit. → Page 37, section
»Draining externally closed applica-
tions«
.

Repeat the steps “Filling”, “Venting”, “Start/Stop circulation” and “Draining” until the drained
thermal fluid remains clear.

Remove the bypass hose after completely draining the temperature control unit.
Leave an application connected, if you have simultaneously rinsed a used application (externally
closed).

Leave the
>Drain<
[8] open for a while to allow the thermal fluid remaining in the temperature
control unit to evaporate.

Close the
>Drain<
[8] once the residual thermal fluid has evaporated.

Dismount the drain hose.

Remove the collecting container.

Discard the collecting container, including its contents, properly. Follow the instructions for the
proper disposal. → Page 15, section
»Proper disposal of resources and consumables«
.

Re-connect your application. (Only if you have rinsed the thermal fluid circuit using a bypass
hose.)

Fill the temperature control unit with thermal fluid. → Page 36, section
»Filling and venting
externally closed application«
.

Vent the temperature control unit. → Page 36, section
»Filling and venting externally closed
application«
. An externally open application does not need to be vented.

Restart the temperature control unit in normal mode.
