PROCEDURE

Check that the >Expansion vessel< [18] was unlocked (see page 33 in section »Locking/unlocking
the expansion vessel [18]« ). The >Expansion vessel< [18] may only be locked when an external-
ly open application is used.

Carefully pour suitable thermal fluid, using the filling accessories (funnel and/or beaker) into the
>Filling port< [17]. The thermal fluid flows from the >Expansion vessel< [18] into the tempera-
ture control unit and via the hose connections to the external application. The fill level is dis-
played in the >Sight glass< [23] or on the >Touchscreen< [88]. Follow the instructions for clean-
ing the filling accessories on page 17 in section »Proper disposal of resources and consuma-
bles« .

Before starting the venting process, fill the >Expansion vessel< [18] from 50 to 70%. The thermal
fluid flows via the >Expansion vessel< [18] into the temperature control unit.

Wait until the level in the >Sight glass< [23] or on the >Touchscreen< [88] no longer drops. Refill
the >Expansion vessel< [18] from 50 to 70 %.

Go to the “Categories Menu”.

Tap on the category “Temperature Control”.

Tap on the category “Start/Stop”.

Tap on the dialog entry “Start venting”.

Confirm your choice by tapping on “OK”.

Confirm the preset time interval by tapping on “OK”. Alternatively, use the numeric keypad that
appears to enter an individual time interval. Confirm your entry by tapping on “OK”. Venting will
start. Venting stops if the level in the >Sight glass< [23] or on the >Touchscreen< [88] drops too
much. Refill thermal fluid (fill level 50 to 70%) and restart venting. Depending on the tempera-
ture control unit and the connected application, this process must be repeated several times.
The venting process can only be restarted after the time interval has elapsed if a time interval in-
dicated in the >Status line< [Field 10] runs backwards.
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 venting. To do this, go to the category “Temperature Control”.

Tap on the category “Start/Stop”.

Tap on the dialog entry “Stop air-purge”.

Confirm your choice by tapping on “OK”. Venting is stopped and the pump continues to run for
approx. 30 seconds. Wait until the pump stops.

Close the >Expansion vessel cap< [22] by hand.
Venting and degassing must be carried out especially during initial commissioning and after chang-
ing the thermal fluid. This is the only way to ensure trouble-free operation. After venting is com-
pleted, follow the steps on page 68 in the section »Degassing externally closed applications« .
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 beyond the minimum mark
of the >Sight glass< [23] or on the >Touchscreen< [88] and at the “highest” working temperature
there should be no overflow from the >Expansion vessel< [18]. In case of overfilling, drain the
overfilled quantity of thermal fluid (see page 70 section »Draining externally closed applica-
tions« ). Check if the thermal fluid can be reused. Please note page 17 section »Proper disposal of
resources and consumables« .
4.4.1.2 Degassing externally closed applications
With a fluid mix, rapid heating can cause thermal fluid to suddenly escape from the >Expansion
vessel< [18]
COMBUSTION/PROPERTY DAMAGE

Due to the rapid heating of the low-boiling component contained in the mixture, a sudden
overflow from the >Expansion vessel< [18] is to be expected.

BURNS TO LIMBS

Do not touch the
>Expansion vessel<
[18] during “degassing” setup mode!

Wear your personnel protective equipment (e.g. temperature-resistant safety gloves, safety goggles).
