Combined filter replacement
If the Filter monitoring option is fitted the requirement for combined filter change is
indicated by the filter alarm signal and LED's not going off after the pre filter has been
changed. For units fitted with the VOC monitor option, the requirement for a
combined filter change (gas portion saturated) is indicated by illumination of the Gas
filter alarm light on the front panel. Please note that the carbon media within the
combined filter is hygroscopic and will absorb moisture from the atmosphere. This is
why the gas filter should be changed every twelve months regardless.
1. Isolate the electrical supply to the extractor.
2. Undo the two catches on the front of the unit and open door.
3. The combined filter is the higher of the two filters (see Fig 11).
4. Rotate the handle below the combined filter through 180° which lowers the filter
5. Using the handle, on the front of the filter, pull it out of the unit being careful to
support it as it comes free as it is heavy.
6. Place a new combined filter into the runners and push it into position.
7. Rotate the handle back through 180° to lock the combined filter in position.
8. Close the door and fasten the two latches.
9. Reconnect the power supply.
