17.4. Filter Replacement
A filter is permanently attached inside the ToxiRAE Pros top cap, which helps to keep
debris and moisture out. This filter should be inspected periodically, and the cap and
rubber insert should be inspected for damage. If the filter is dirty or the cap or rubber
insert shows signs of damage, replace the entire instrument cap assembly, including the
cap, screw, filter, and the rubber insert (part number G02-0305-003, package of three).
To replace the cap assembly:
1. Remove the top cap. First remove the small Phillips screw on the back side:
2. Then use the special tool (part number G02-0306-003, package of three) and
apply leverage at the middle of the instrument to push the top cap loose, and then
remove it with your fingers.
