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 Unit

This section describes the replacement procedure for the heater unit.
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 unit reaches high temperatures

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

is off and the heater unit temperature has returned to normal room temperature.

For details, refer to IM11M12A01-21E “Heater Assembly“.

NOTE

If the heater strut assembly can not be removed because a screw has fused to its thread, one of

our service representatives can fix it.
