Installing the sensor head

Once your installation plan is complete and you have gathered all the necessary tools, you can proceed
with installation of the CoreSense™ M10 multi-gas monitoring system.

Precautions

WARNING
Do not grab the sensor head by the mounting threads. Thread edges are sharp and pose
a risk of personal injury.
WARNING
Do not handle the sensor head by the attached conduit. This could break the interface
between the conduit and the fitting, possibly losing the IP rating and allowing for
substance (water) ingress.
NOTICE
Do not expose sensor head innards to rain or snow.
The CoreSense M10 sensor head is delivered with the thermal pump turned OFF. When installation
is complete and the sensor head is in contact with oil, make sure to enable the thermal pump (see
"Activating the thermal pump" on page 69).
NOTICE
The thermal pump is designed to operate while immersed in transformer oil. It will fail
within minutes if operated in air.
