How to Replace Sensor

When the sensor has deteriorated, replace it with a new sensor. As for the part number, see

CMPL at the end of this manual. Be sure to perform calibration after replacing the sensor.
Replace the sensor according to the following instructions.

7.3.1

Removing Sensor

(1) Turn off the power, and be sure to pull the power cord out of the socket.
(2) Wait for about 1.5 hours until the heater temperature falls to the ambient temperature level.

WARNING

Be sure to replace the sensor after the heater temperature has fallen sufficiently. Not doing so

may cause burn injuries.

(3) To remove the upper cover, remove set screws at three points on the rear panel of the

OX400.

(4) Slide the upper cover backwards and remove it upwards.
