NOTE

Optional Inconel bolts have a high coefficient of expansion. If excess torque is applied while

the bolts are being tightened, abnormal strain or bolt breakage may result. So, tighten the bolts

following the instructions given above.

11.1.3

Replacement of the Heater Assembly

This section describes the replacement procedure for the heater assembly.
The sensor or ceramic heater-furnace core internal structure is subject to fracturing, so do

NOT subject it to strong vibrations or shock. Additionally, the heater assembly reaches high

temperatures and is subjected to high voltages.
So, maintenance services should be performed after the power is off and the heater assembly

temperature has returned to normal room temperature.
For details, refer to IM 11M12A01-21E “ Heater Assembly “.

NOTE

If the heater assembly can not be removed because a screw for the heater assembly fixation has

fused to its thread, one of our service representatives can fix it.
