Tubing (optional)
Sample and exhaust tubing calculations
This table shows the flow rate, tubing length, transport time, and maximum
pressure and vacuum at the inlet and exhaust points�
Tubing lengths vary among gases� If the pressure or vacuum on the inlet/exhaust
lines does not meet the recommended values, the detector may encounter flow
faults� The maximum total tubing length (inlet + outlet) is 100 ft� (30 m)�

The overall maximum load on the pump between the inlet and the exhaust should not exceed 10 inches H
NOTE
Use Teflon Fluorinated Ethylene Polymer (FEP) tubing to ensure proper sample
transport�
An external filter must be installed on the detector's "in" line, either at the
detector, for local monitoring, or at the end of the sampling line, for remote
monitoring� A filter can also be installed on the exhaust port to reduce noise�
