 Leave the >Drain< [8] open for a while to allow the thermofluid to evaporate in the temperature
control unit.
 Close the >Drain< [8] once the residual thermofluid has evaporated.
 Dismount the drain hose.
 Remove the collecting container.
 Discard the collecting container, including its contents, properly. Follow the instructions on page
16, section »Proper disposal of resources and consumables« for the disposal of thermofluid.
 Re-connect your application. (Only if you have rinsed the thermofluid circuit using a bypass
hose.)
 Fill the temperature control unit with thermofluid, as described on page 64 in section »Filling
and venting externally closed application« or on page 69 in section »Filling and venting exter-
nally open application«.
 Drain the temperature control unit as described on page 64 in section »Filling and venting ex-
ternally closed application«. An externally open application does not need to be vented.
 Start the “degassing” function as described on page 66 in section »Degassing externally closed
applications«. An externally open application does not need to be de-gassed.
 Restart the temperature control unit in normal mode.
7.5 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. Follow the in-
structions on page 16, section »Proper disposal of resources and consumables« for the disposal of
cleaning agents and material.
7.6 Inspect the mechanical seal
No visual inspection of the drip tray
MATERIAL DAMAGE IN THE TEMPERATURE CONTROL UNIT BY OVERFLOW OF THE DRIP TRAY
 Check the drip tray on a monthly basis and empty it when necessary.
Expect drop formation at the mechanical seal when operating with thermofluids that evaporate only
very slowly, as mechanical seals are never absolutely tight. These drops must be collected in a con-
trolled fashion. The drip tray must be regularly checked and emptied if necessary (see page 83,
section »Function check and visual inspection«). Follow the instructions on page 16, section
»Proper disposal of resources and consumables« for the disposal of thermofluid.
7.7 Plug contacts
Exposed plug contacts
DAMAGE CAUSED BY FLUID INGRESS
 Protect unused plug contacts with the protective caps supplied.
 Clean surfaces only with a damp cloth.
Protective caps are supplied for all plug contacts. Make sure that any plug contacts not required are
protective with the caps.
