Perform the following steps without attaching a short circuit hose, if the application used by you (exter-
nally closed) is also dirty. In this case, leave your externally closed application connected to the tempera-
ture 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 41, section
»Filling and venting with >Level indicator and drain< [38]«
.

Vent the system. → Page 41, section »Filling and venting with >Level indicator and drain< [38]« .

Adjust the
setpoint
and the cut-out value of the
overtemperature protection
to the thermal
fluid used. → Page 36, section
»Set/change setpoint«
and → Page 37, section
»Setting the over-
temperature (OT) protection« .

Start
the
circulation
. The length of rinsing depends on the level of soiling.

Stop
the
circulation
.

Drain the temperature control unit. → Page 43, section »Draining with >Level indicator and
drain< [38]«
.

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 temperature control unit open for a longer while to allow the thermal fluid remaining
in the temperature control unit to evaporate.

Reinsert the hose into the >Level indicator and drain< [38].

Remove the collecting container. 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 system. → Page 41, section »Filling and venting with >Level indicator and drain< [38]« .

Vent the system. → Page 41, section »Filling and venting with >Level indicator and drain< [38]« .

Restart the temperature control unit in normal mode.
7.4 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).
Exposed plug contacts
DAMAGE CAUSED BY FLUID INGRESS

Protect unused plug contacts with the protective caps supplied.

Clean surfaces only with a damp cloth.
A standard stainless steel cleaning agent is suitable for cleaning the stainless steel surfaces. Carefully
clean painted surfaces (damp only) using a solution of sensitive-fabrics detergent. Observe the
proper disposal of thermal fluid and aids. → Page 15, section »Proper disposal of resources and
consumables« .
7.5 Inspect the mechanical seal
No visual inspection of the mechanical seal
MATERIAL DAMAGE IN THE TEMPERATURE CONTROL UNIT CAUSED BY LEAKING MECHANICAL SEAL

Check the mechanical seal once a month.

If case of leakage, stop the temperature control unit and contact Customer Support. → Page
58, section »Contact data« .
