SERIES 2000 ELECTRONIC TEMPERATURE SENSORS Immersion Well Mounting (C7021D, C7031D, C7031D, C7041D) NOTE: Mounting using previously installed Honeywell wells (part no.: 32005960-001) requires an adapter (part no.: 50001775-001). NOTE: The C7021D, C7023D, C7041D uses the 50001774-001 Well Assembly. See Fig. 5 for dimensions. The C7031D Sensor includes an immersion well. The C7021D, C7023D, C7041D Sensors do not include a well; order the well as an accessory (part no.: 50001774-001). 1.

SERIES 2000 ELECTRONIC TEMPERATURE SENSORS Strap-on Mounting (C7021K, C7023K, C7041K, T775-SENS-STRAP) SENSOR The C7021K, C7023K, C7041K and T775-SENS-STRAP Sensor mounts on metal pipes from 1-5/8 inch to 5 inches in diameter using the straps supplied. Clean the pipe surface where the sensor makes contact before mounting. If necessary, remove pipe insulation at the installation point. Thermal compound is recommended. Locate the sensor on the discharge pipe within 3 ft. (0.9 m) of the boiler. See Fig. 6.
