2. Provide a drip loop in the capillary if the body is mounted in any position other than
upright. The thermal element is usually located on the downstream side of the coil.
3. Allow slack so that the capillary is not taut. Install the thermal element securely in the
controlled media for maximum sensing capability and minimum vibration damage.
4. Serpentine the element in a horizontal pattern so that it is exposed to all areas where
low temperatures are possible. See Figure-3.
5. Secure the element into place using the five capillary clips provided.
6. Remove the cover. See Figure-4.
7. Mount the case with two screws (#10 maximum) in the screw slots in the back of the
case. See Figure-6.
8. Connect the appropriate wiring. Follow the wiring instructions in the Wiring section.
