S ECTION 2
SETUP AND INSTALLATION
7. Select a location on the pump tubing to install the vacuum gauge. It
should allow the gauge to be easily monitored (Thermo Scientific
suggests a location about half a meter from where the tubing is installed
in the pump connection on the back of the unit.) Cut the tubing and
install the two ends into the quick-connect fittings on the vacuum
gauge.
8. From the 10m length of tubing for the bypass line, cut a piece of tubing
long enough to reach from the water trap filter to the bypass filter on
the back of the 1405 unit (Figure 2-21 and 2-23). Install the tubing into
the quick-connect fittings on the water trap filter and bypass filter.
Note. The bypass tubing will be connected to the bypass
connection on the flow splitter and to the water trap when you
assemble and install the sample inlet on top of the enclosure later
in this section. ▲
9. Ensure that the sample tube is properly installed in the flow splitter
(refer to “Adjusting the Flow Splitter” earlier in this section).
10. Install the sample tube from the flow splitter through the roof opening
(Figures 2-24 and 2-25).
Note. Cap the extra opening in the enclosure roof. ▲
