To connect a charcoal filter
1. Load the Teflon ferrules into the nut. The nut and ferrules are supplied with the filter. See
Figure 3.
2. Connect the nut to the DataFID inlet. Do not tighten the nut.
CAUTION: Over-tightening the Teflon ferrules will result in damage to the ferrules.
3. Remove the charcoal filter from its plastic bag and insert it into the nut. Finger-tighten the nut
onto the inlet. If the filter is not secure, ensure you have inserted the tube stub far enough into
nut. Do not over-tighten the fitting.
Figure 3. Connecting the Charcoal Filter
The charcoal filter will remove hydrocarbon contaminants for up to 4000 ppm hours. This means that the
filter will be good for 1 hour removing 4000 ppm of hydrocarbon contaminants or will last for 4 hours
removing 1000 ppm. The exact time will be determined by the operating environment. You will notice an
increased hydrocarbon background when the filter requires replacement.
To replace the charcoal filter
1. Loosen the nut on the DataFID inlet.
2. Remove the used filter.
3. Insert the new charcoal filter into the nut and finger-tighten the nut onto the inlet. Do not over-
tighten the fitting.
4. When the charcoal filter is not in use, place it in its plastic bag and store it in a clean, dry place.
