Mounting and Wiring
Immersion probes measure the temperature inside
pipes carrying liquid or steam and are installed in a
304 stainless-steel thermowell. Mount the thermow-
ell horizontally or with the open end facing down
(to allow any condensation to drain). Position the
thermowell to prevent contact with the inside of the
pipe.

2. Install the thermowell. (See the Accessories
section.)
3. Fill the well with thermal compound to ensure
complete conductivity from well to probe.
NOTE: The probe can slide within its collar on the
case as it is inserted into the thermowell.
4. Remove the screws holding the cover to the case
