(2) Replacement interval for the disk filter (P/N K9424GQ) varies depending on dust
content in the sample gas. Check the cleanness of element to determine the filter
replacement cycle. The felt filter (P/N K9346WH) is for preventing the activated
carbon from leaking so it requires no replacement unless abnormal conditions occur.
(3) Increasing contamination of the filter may deteriorate the flow rate of sucked sample
gas. The flow rate should be checked regularly by the flowmeter of the sampling
unit. If the flow rate is outside of the specified range 500
6
100 ml/min, readjust
the flow rate.
