CAUTION:
Ensure the absolute cleanliness of the filter element is maintained during the entire servicing period.
No dirt or impurities should penetrate the filter. The new elements should remain packaged until they are installed
to prevent contamination. While removing an element from the a recently out of operation filter housing, make
sure the element is fully discharged from any voltage caused by static charging during operation with certain fluids
Do not damage element seals during servicing. All sealing have to be checked on a regular basis to avoid leakage
and potential development of an explosive atmosphere. Any damaged seals will need to be replaced. Any
damaged seals have to be replaced.
FAILURE TO FOLLOW THIS WARNING COULD LEAD TO DEATH,
SEVERE INJURY, OR PROPERTY DAMAGE.
5. Cleaning of the filter element
Microglass (VG) or paper (P) filter media cannot be cleaned and need to be replaced when the dirt-holding capacity is reached.
Wire mesh (G) filter media can be cleaned and used again. Follow the cleaning specification for Eaton filter elements, sheet no.
21070-4 and 39448-4 to clean wire mesh filter media.
6. Pressure difference measuring
If the filter assembly includes a clogging indicator, the indicator will measure the pressure difference across the filter element. The
method of pressure reading varies depending on the type of indicator installed. It can be a visual, visual-electric or electronic
reading. Additionally the G ¼" connections from the switchgear can be used for external pressure gauges. Measuring connections
are recommended on data sheet 1650.
