Inserting the separation tube
1. Unscrew the front of the sampling probe from the base.
2. Slip the tube into the rubber holder in the front portion. Make sure the arrow on the side of
the tube points toward the instrument.
Insert the other end of the tube into the middle of the base while turning the front portion to
tighten it onto the base's threads.
Note: When the UltraRAE 3000+ is used for VOC monitoring, no tube is inserted.
Do not overtighten any portion of the sampling assembly.
To ensure that there are no leaks, periodically test the seals:
With the UltraRAE 3000+ running, place your finger over the end of the inlet probe. The alarm
should sound and the pump-stall icon should flash on the display. This indicates that all seals
are good. Stop the alarm by pressing [Y/+]. If the pump does not alarm or show the stalled-
pump icon, then check that all inlet parts are tight and inspect the O-ring for damage (replace
it if necessary).
