Replacement of Pump Unit
For the replacement of pump unit, see "Detaching and Attaching Pump Unit" in "3-3. Names and functions
for each part".
Replacement of flow sensor, fan and catalyst tube
After the flow sensor, fan or catalyst tube is replaced, the operation must be checked by a qualified service
engineer. Since the catalyst tube has an influence over gas sensitivity, calibration needs to be performed
after replacement. Please contact RIKEN KEIKI.
