4.3.10 Closing the housing cover
Devices with EPDM cover seal - transmitter leakiness!
Mineral-based, animal-based or vegetable-based lubricants cause the EPDM cover seal to swell
and the transmitter to become leaky.
‣ The thread is coated at the factory and therefore does not require any lubrication.
The housing cover can no longer be closed.
Damaged thread!
‣ When closing the housing cover, please ensure that the thread of the cover and housing are
free from dirt, e.g. sand.If you feel any resistance when closing the cover, check the thread
on both again to ensure that they are free from dirt.

closed with a screw. These screws should be tightened handtight (2 Nm (1.48 lbf ft)) to the stop
to ensure that the covers sit tightly.
