2.1.8
Orientation of cable glands
When the level switch is mounted horizontally, ensure the cable glands are
pointed downwards to avoid water getting inside the housing. Unused
conduit entries must be completely sealed with a suitably rated stopping
(blanking) plug.
2.1.9
Seals
Apply PTFE tape to the threaded process connection or use a flat gasket. This
is required for a silo (or other vessel) to maintain the process pressure.
2.1.10 Future maintenance
It is advisable to:
•
Grease the screws of the housing cover (lid) when a corrosive
atmosphere is present.
•
Use PTFE tape to avoid seizing of aluminum process connection thread
with the socket.
This will help prevent difficulties when the cover needs to be removed
during future maintenance tasks.
