7.6 Inspect the mechanical seal
Only valid for circulation pumps with mechanical seal.
7.6.1 With drip tray
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 86,
section »Function check and visual inspection« ). Follow the instructions on page 17, section
»Proper disposal of resources and consumables« for the disposal of thermofluid.
7.6.2 Without drip tray
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 98, section »Contact data« .
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 86,
section »Function check and visual inspection« ). The tightness of the mechanical seal must be visually checked.
In case of a leakage, more thermal fluid exits at the bottom of the temperature control unit. Follow the instruc-
tions on page 17, section »Proper disposal of resources and consumables« for the disposal of thermofluid.
7.7 Plug contacts
Exposed plug contacts
