2. If it is damaged, use the following procedure to remove the thermocouple adaptor
(G) from the sensor holder (E).
a. Use a propane torch to heat the thermcouple adapter to 232 °C (450 °F)
minimum.
b. While heating, use a flat-head screwdriver to apply removal torque. Apply torque
until the pipe thread sealant softens. Remove and discard the thermocouple
adapator.
c. Use MEK or methylene chloride solvant to clean the thread sealant residue from
the internal pipe threads in the sensor holder. Refer to the applicable MSDS sheet
for solvent handling precautions.
CAUTION!
EQUPMENT DAMAGE
Always remove the stainless steel balls (approximately 200) from the sensor holder
before removing or installing the pre-heater. Turning the pre-heater in the sensor
holder with the stainless steel balls in place will cause permanent damage to the pre-
heater.
3. If the pre-heater (B) is to be removed, clamp the flats of the sensor holder (E) in vise
jaws with plug (D) pointing up. Remove the plug. Unclamp the sensor holder and
pour the stainless steel balls (C) into a container.
Note
The pre-heater should only be removed when the pre-heater or sensor holder is damaged. If
removal is not required, leave the pre-heater installed in the sensor holder.
4. Unthread and remove the pre-heater.
5. Use a cleaning solvent to thoroughly clean the stainless steel balls (C) and pre-heater
chamber in the sensor holder (E).
Refer to the applicable MSDS sheet for solvent handling precautions.
