The pump flow can be closed by using
>Circulation flow<
[1] and
>Circulation return<
[2]
but do
not do so
while the temperature control unit is in operation. The pump may be switched off due to
overheating or high power consumption if the temperature control unit is operated with a shut
pump flow.
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 as described on page 58 in section
.
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. The filling process is
described on page 56 in section
»Filling and venting externally open application«
.
Vent
the system as described on page 56 in section
»Filling and venting externally open application«
.
Adjust the
setpoint
and the cut-out value of the
overtemperature protection
to the thermal
fluid used. The procedure can be found on page 55 in section
and on
page 43 in section
»Setting the overtemperature 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 process”.
Confirm your choice by tapping on “OK”. The length of rinsing depends on the level of soiling.
Tap on the category “Start/Stop”.
Tap on the dialog entry “Stop temperature control process”.
Confirm your choice by tapping on “OK”. The temperature control process is stopped.
Drain
the thermal fluid as described on page 58 in section
»Draining externally open applica-
.
Repeat the steps “Filling”, “Venting”, “Start/Stop temperature control process” and “Draining”
until the drained thermal fluid remains clear.
Leave an application connected, if you have simultaneously rinsed a used application (externally
open).
Leave the rear and front
>Drain<
[10] open for a while to allow the thermal fluid remaining in the
temperature control unit to evaporate.
Close the front and rear
>Drain<
[10] once the thermal fluid has evaporated.
Remove the collecting container.
Discard the collecting container, including its contents, properly. Follow the instructions for the
disposal of thermal fluid on page 15 in Section
»Proper disposal of resources and consumables«
.
Fill the temperature control unit with thermal fluid, as described on page 56 in Section
and venting externally open application«
.
Vent the temperature control unit as described on page 56 in Section
. An externally open application does not need to be vented.
Start the function „Degassing“, as described on page 57 in Section
. An externally open application does not need to be de-gassed.
Restart the temperature control unit in normal mode.

Cleaning the surfaces
Extremely hot / cold surfaces, connections and thermal fluids
BURNS/FREEZING OF LIMBS
Surfaces, connections and tempered thermal fluids can be extremely hot or cold depending on
the operating mode.
Avoid direct contact with surfaces, connections and thermal fluids!
Wear your personnel protective equipment (e.g. temperature-resistant safety gloves, safety
goggles).
