5.3 Particulate Filter Element Replacement
Used on Natural Gas systems only!
Life expectancy of the filter element is dependent upon operating conditions in each
specific application. As a minimum, it is recommended that the membrane filter
element be changed every 12 months. If inspection of the removed element shows that
it is in poor/good condition after 12 months operation then the operating period
between replacements may be reduced/increased accordingly.
To replace the particulate filter element, proceed as follows:
1.
Isolate the sampling system from the gas supply in accordance with the System
Shutdown Procedure.
2.
Unscrew and remove the filter hex nut from the body of the filter (F1)
- Take
care not to lose the spring inside the nut!
3.
Carefully prise out the sintered filter element from the filter body and
clean/discard the filter element.
4.
Push fit a cleaned/new filter element
(Michell Part No. CD2-PFE).
5.
Replace the filter hex nut back onto the body of the filter until it reaches a
mechanical stop by hand – Tighten (nip) up with a spanner/wrench
- Ensure the
spring is present inside the nut!
6.
Resume normal system operation as described in the System Start-Up
Procedure.
Used on Trace Moisture systems only!
Life expectancy of the filter element is dependent upon operating conditions in each
