To replace charcoal in a charcoal filter, use the following procedure:
1. Remove the sampling assembly from the probe by loosening the probe nut and
pulling the sampling assembly free from the probe.
2. Unscrew the cap from the sampling assembly. This will expose the end of the charcoal
filter cartridge. See diagram below.
3. Tip the cartridge up and empty the charcoal from the cartridge.
4. Clean the inside of the cartridge with a cotton swab dipped in isopropyl alcohol.
5. Dry the cartridge thoroughly.
6. Re-fill the cartridge with new “dust-free” charcoal of the type specified for the filter.
7. Apply Teflon tape to the male threads of the charcoal cartridge and screw on the
cap.
8. Re-insert the sampling assembly into the probe and tighten the probe nut.
