NOTES:
FOR PROCESS TEMPERATURES BELOW -29_C (-20_F) AND ABOVE 204_C (400_F) SENSOR MATERIALS
MUST BE APPROPRIATE FOR THE PROCESS - SEE TABLE 9.
2. IF AMBIENT DEW POINT IS ABOVE PROCESS TEMPERATURE, ICE FORMATION MIGHT CAUSE INSTRUMENT
MALFUNCTION AND REDUCE INSULATOR EFFECTIVENESS.

CAUTION
Measurement errors can occur if the torque tube assembly is bent or misaligned during installation.
1. When mounting a DLC3020f on a 249 sensor, secure the shaft extension to the sensor torque tube shaft via the
shaft coupling and set screws, with the coupling centered as shown in figure 7.
2. Slide the access handle to the locked position to expose the access hole. Press on the back of the handle as shown in
figure 2 then slide the handle toward the front of the unit. Be sure the locking handle drops into the detent.

3. Remove the hex nuts from the mounting studs.
4. Position the insulator on the digital level controller, sliding the insulator straight over the mounting studs.
5. Install 4 washers (key 78) over the studs. Install the four hex nuts and tighten.
