
Start the circulation by pressing the
>Start/Stop button<
[E].

Refill thermal fluid. Observe the fill level in the
>Level indicator/Level<
[25] The filling/venting
process is complete when the thermal fluid is 1 cm below the max. mark of the >Level indica-
tor/Level<
[25].
If, with externally closed applications (reactors), the fluid level in the fill level display remains the same
when the pump is running and when the pump has stopped, the application has been vented.

Stop the circulation by pressing the
>Start/Stop button<
[E].

Switch off the temperature control unit.

Manually close the
>Filling port<
[17].

Check the level of the collecting container at regular intervals. Empty the container when neces-
sary and dispose of its contents properly.

Manually close the
>Filling port<
[17].
The temperature control unit is now filled.
Venting
must be performed especially during commissioning and after a change of thermal fluid. This is
the only way to ensure trouble-free operation.
Note that the volume expansion of the thermal fluid depends on the working temperature range you
wish to work in. At the “lowest” working temperature, do not go below the minimum mark of the >Lev-
el indicator/Level<
[25] and at the “highest” working temperature, do not go above the maximum mark.
In case of overfilling, drain the excess amount of thermal fluid. → Page 37, section
»Draining externally
closed applications« . Check if the thermal fluid can be reused. Follow the instructions for the proper
disposal. → Page 15, section »Proper disposal of resources and consumables« .

Hot or very cold thermal fluid
SEVERE BURNS/FROSTBITE OF LIMBS

Before draining, ensure that the thermal fluid has room temperature (20 °C).

If, at this temperature, the thermal fluid is too viscous to be drained: Control the temperature
of the thermal fluid for a few minutes until the viscosity will allow drainage. Never control the
temperature of the thermal fluid when the drain is open.

Danger of burns when draining thermal fluids at temperatures above 20 °C.

Wear your Personal Protective Equipment for draining.

Only drain using suitable drainage hose and collecting container. These must be compatible
with the thermal fluid and its temperature.
PROCEDURE
Temperature control units with >Drain valve thermal fluid< [3].

Remove the knurled screw at the >Drain< [8].

Connect a suitable drain hose to the >Drain< [8].

Place the other end of the hose in a suitable container.

Open the >Drain valve thermal fluid< [3] by turning it counterclockwise (turn 90° left as far as it
will go). The thermal fluid will flow from the external application via the temperature control unit
and the draining hose into the container. Check if the thermal fluid can be reused. Follow the in-
structions for the proper disposal. → Page 15, section »Proper disposal of resources and con-
sumables« .

Wait until the external application and the temperature control unit are empty.

Open the connection >Circulation flow< [1].

Open the connection >Circulation return< [2].

Leave the temperature control unit open for a while to allow it to dry out and the residue to
drain. Without screw caps and with >Drain valve thermal fluid< [3] open.

Close the >Drain valve thermal fluid< [3] by turning it clockwise (turn 90° right as far as it will
go).

Close the connection >Circulation flow< [1].

Close the connection >Circulation return< [2].

After drying out, remove the drain hose and re-fit the knurled screw to the >Drain< [8]. The
temperature control unit is now drained.
