Ending A Combustion Test; Emptying The Water Trap - Bacharach PCA3 Operation And Maintenance Manual

5.10. Ending a Combustion Test

WARNING: Burn Hazard. Do not touch the probe after removing it
from the stack. Allow the probe to cool before handling (about 5
minutes).
1. Remove probe from stack.
2. Allow the pump to run until all combustion gases have been flushed
from the analyzer with fresh air as indicated by the O
to 20.9%.

5.11. Emptying the Water Trap

The Water Trap / Filter Assembly removes stack gas condensate, and also
prevents soot from contaminating the internal components of the analyzer.
IMPORTANT: Use the Water Trap / Filter Assembly in a vertical
position with the gas flow arrow pointing up as shown in the
illustration below.
1. Empty the water trap chamber after each combustion test, or stop the
test and empty the chamber if the liquid condensate level approaches
the tip of the riser tube.
2. To empty the trap, first pull apart the two halves of the Water Trap using
a slight twisting motion; empty the water trap chamber; and then
reassemble the trap.
3. After each combustion test, check the Water Trap's filter element. If it is
dirty, replace the filter (see Replacing the Filter Element on page 87).
