MicroFID Software Manual
Replace the filter on a weekly basis, or more frequently if MicroFID
is used in a dusty or wet environment. You must replace the filter if
MicroFID has been exposed to liquid water. The pump will sound
labored when the filter requires replacement.
NOTE: Do not replace the inlet filter in a hazardous location.
1. Turn the instrument off. Unscrew the filter housing
from the detector housing. Be careful not to lose the O­
ring seal. See Figure 23.

2. Remove the Teflon/Polypropylene filter and install the
new filter (Part No. MX396020 or MX396015). Place
the filter in the filter housing with the Teflon side
facing down in the filter housing and the mesh side
facing the MicroFID. Handle the filter disk only by the
edges. The mesh may be damaged or contaminated by
excessive handling. Use forceps if possible.
NOTE:
Each filter is protected by a piece of blue plastic. Remove the
plastic before installing the filter in MicroFID.
3. Replace the filter housing.
4. Calibrate all Cal Memories, that you are using, before
continuing operation.
NOTE:
Do not operate MicroFID without an inlet filter.
