Information on Class I location seals can be found in the NEC, Article 501-5.

Once correctly installed, the Model S4000T requires little or no maintenance, other
than periodic calibration checks to ensure system integrity. General Monitors
recommends that a schedule be established and followed.
NOTE - The system’s full two-year warranty will be voided if customer personnel or
third parties damage the system during repair attempts.
Sensor heads exposed to the elements may require lubrication of the mounting
threads. Grease must not be used. As an alternative, PTFE (teflon) tape may be
used.
NOTE - Do not use any material or substance on threads that contact the sensor
housing.
The removal of particulate matter from sensor accessories may be done through the
use of an appropriate halogen-free solvent. Water or ethanol are examples of
suitable solvents. The accessories should be thoroughly dried, with compressed air if
necessary, before refitting to the sensor body.
