5.4.2 Drain and Exhaust Connections
The BioTector should be installed in a well-ventilated area with the exhaust port
piped to an external vent. The installation should be carried out in accordance
with Section 1 Safety Precautions.
All BioTector drain tubing must be positioned correctly so that any liquid pumped will drip freely into a larger
drain chamber. The correct positioning and setup of the drain ports prevent liquid accumulation and
measurement errors. All drain ports should be directed to a well ventilated area as oxygen and other gases
may be released during the analysis. The drain tubes should be at atmospheric pressure and should not be
subjected to any back pressure as this may result in measurement errors. The exhaust tube should be piped
out to a well ventilated area as oxygen and other gases will be released during the analysis. The end of this
tube should be positioned in a downward position so that water condensation and freezing will not occur
during winter months. Figure 16 illustrates BioTector connections including the Sample, Manual grab sample,
Sample Out (drain) and the Exhaust connections.
