Appendix B
Install Water Trap Bottle
The translucent bottle that attaches to the bottom of the inner inlet is used to
collect any water that is drawn into the sampled flow. This prevents water
from reaching the D
USTTRAK monitor and damaging it. The bottle is
installed on the Environmental Enclosure when it is shipped. If the bottle is
removed for cleaning, follow these precautions when re-installing:
• Before screwing the bottle into inner inlet ring, be sure that the O-ring
found in the bottom of the threaded hole is greased. This ensures an air-
tight seal.
• When threading the bottle into the inlet be careful not to damage its
threads. Figure B-5 demonstrates how to install the water trap correctly.
• Make sure the bottle has been tightened securely.
