Inspect the mechanical seal
No visual inspection of the mechanical seals
MATERIAL DAMAGE IN THE TEMPERATURE CONTROL UNIT CAUSED BY LEAKING MECHANICAL
SEALS
Check the mechanical seals once a month.
If case of leakage, stop the temperature control unit and contact Customer Support. The tele-
phone number can be found on page 84, section
.
Expect drop formation at the mechanical seal when operating with thermal fluids that evaporate
only very slowly, as mechanical seals are never absolutely tight. These drops must be removed if
necessary (see page 74, section
»Function check and visual inspection«
). The tightness of the me-
chanical seal must be visually checked. In case of a leakage, more thermal fluid exits at the bottom
of the temperature control unit. Follow the instructions on page 15, section
for the disposal of thermofluid.

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.

Decontamination/repairs
Returning a not decontaminated temperature control unit for repair
PHYSICAL INJURY AND PROPERTY DAMAGE CAUSED BY HAZARDOUS MATERIALS IN OR ON THE
TEMPERATURE CONTROL UNIT
Carry out appropriate decontamination.
The decontamination process depends on the type and quantity of the materials used.
Consult the relevant safety data sheet.
You will find a prepared return receipt at www.huber-online.com.
As the responsible body you are responsible for carrying out decontamination
before
third-party
personnel come into contact with the temperature control unit / accessory. Decontamination must
be carried out
before
the temperature control unit / accessory is returned for repair or inspection.
Attach a clearly visible written notice stating that the temperature control unit / accessory has been
decontaminated.
To simplify the process, we have prepared a form for you. This is available for download at
