Replacing the dust separator filter cartridge
The only part that may require field replacement during servicing is the dust
separator filter cartridge. The “FILTER” LED will illuminate when the detector’s air
filter needs to be changed.
WARNING: If, due to the environment of the area being protected, the dust in the
dust separator filter will expose maintenance personnel to health hazards, it is
recommended that suitable masks and protective clothing be worn when changing filters.
Maintenance work should be performed in compliance with OSHA if applicable.
Note: Used dust separator cartridges are not intended for reuse and should be
discarded.
To replace the filter:
1. Remove power to the detector.
2. Remove the front cover mounting screw securing the unit’s front cover.
3. With the front cover removed, grasp the filter firmly and pull the filter out (directly
towards you).
4. Properly dispose of the used cartridge.
5. Locate the orientation markings on the new filter cartridge. The word “IN” is
marked on one side and the other is marked “OUT”.
6. Insert the replacement filter cartridge (part number 33-30755 ) so that the “IN”
mark on the cartridge is on the left as viewed in Figure 14 on page 41.
7. Slide the cartridge all the way into place.
8. Replace the detector cover and secure it into place. Initiate a FastLearn routine
by re-energizing the detector.
