7-5. How to replace parts
<Replacement of Consumables>
External Dust Filter Replacement
Because the external dust filter may gradually get dirty or clogged over the time,
it must be replaced regarding the operating conditions. Check the external dust
filter, and then replace it as necessary.
Fuse replacement
Make sure that the power switch of the main unit is turned OFF and the power
plug is disconnected from the outlet.
While pushing the fuse holder, turn it counterclockwise by approximately 90
degrees and pull it out (see the right figure).
Replace the fuse with new one.
Return the fuse holder, and push and turn it clockwise by approximately 90
degrees.

NOTE

The above replacement intervals are recommendation only. The intervals may change depending on the
operating conditions. These intervals do not mean the warranty periods either.

After the sensor unit or catalyst tube is replaced, always perform a calibration (zero adjustment and span
adjustment).

There are two types of sensor units and catalyst tubes: one for C4F6/C5F8 and the other for COS.
Replace them with appropriate ones.

To reduce the frequency of calibration, it is recommended that the sensor unit and catalyst tube be
replaced at the same time.
WARNING
To prevent fire, use a fuse with the specified ratings (3.15A, 250V and Time Lag) for the gas detector.
Turn the POWER switch OFF and disconnect the power plug from the outlet before replacing a fuse. Do
not use an unspecified fuse or short-circuit the fuse holder.
