PROCEDURE
 Drain the temperature control unit as described on page 66 in section »Draining the bath ther-
mostat«.
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 end of the drain hose.
 Close the drain valves on the temperature control unit by turning them clockwise (turn 90° right
as far as it will go).
 Connect the >Circulation flow< [1] with the >Circulation return< [2] to the temperature control
using a bypass hose.
If the application used by you (externally closed) is also dirty, perform the following steps without
attaching a short circuit hose. In this case, you leave your external closed application connected to
the temperature control unit. Thus clean the temperature control unit and your application the
same time.
When using Huber thermal fluids to clean the thermal fluid circuit, use ethanol.
PROCEDURE
 Fill the system (minimum fill level) with the cleaning agent. The description can be found on page
64 in section »Filling and venting the bath thermostat and the externally closed application«.
 Vent the system as described on page 64 in section »Filling and venting the bath thermostat
and the externally closed application«.
 Go to the “Categories Menu”.
 Tap on the category “Temperature Control”.
 Tap on the category “Start/Stop”.
 Tap on the dialog entry “Start circulation”.
 Confirm your choice by tapping on “OK”. The length of circulation depends on the level of soiling.
 Tap on the category “Start/Stop”.
 Tap on the dialog entry “Stop circulation”.
 Confirm your choice by tapping on “OK”. The circulation is stopped.
 Open the >Drain< [8] and drain the detergent through the draining hose into a suitable container
(such as the original canister, which is compatible with the cleaning agent).
 Repeat the steps “Filling”, “Venting”, “Start/Stop circulation” and “Draining” until the drained
ethanol remains clear.
 Remove the bypass hose.
Leave an application connected, if you have simultaneously cleaned a used application (externally
closed).
 Leave the >Drain< [8] open for a while to allow the cleaning agent to evaporate in the tempera-
ture control unit.
 Close the >Drain< [8] once the residual cleaning agent has evaporated.
 Dismount the drain hose.
 Remove the collecting tank.
 Discard the collecting container, including its contents, properly.
 Re-connect your application. (Only if you have cleaned the thermal fluid circuit using a bypass
hose.)
 Fill the temperature control unit with thermal fluid, as described on page 64 in section »Filling
and venting the bath thermostat and the externally closed application«.
 Drain the temperature control unit as described on page 64 in section »Filling and venting the
bath thermostat and the externally closed application«. An externally open application does
not need to be vented.
 Start the “degassing” function as described on page 65 in section »Degassing of bath thermo-
stat«. An externally open application does not need to be off-gassed.
 Restart the temperature control unit in normal mode.
