e. Connect the power cable (not shown) from the power control box and power strip A.
f. Use the long gray cable to connect the power control box to the Heated Valve Drawer.
2. Connect the Heated Transfer Line (HTL).
a. Connect the HTL between the IGS gas cell and the HVD. Place the end with the electrical
connectors towards the HVD.
Note The line to the IGS is distinct from the Heated Sample Line from the sample source.
The Heated Sample Line from the source to the Heated Valve Drawer is much longer,
while the shorter Heated Transfer Line connects the HVD to the IGS gas cell.
b. Connect the electrical round black cable from the HTL to the back of the Heated Valve
Drawer.
3. Connect the remaining un-heated gas lines.
4. Connect the gas cell outlet to the condensate filter inlet.
5. Continue connecting each of the gas lines according to the plumbing diagram for your system.
See "Automatic Pressure Control System"
6. Install the thermal insulation wrap on the bare tube connections of the HTL and HSL.
Ventilation
This system is designed for vacuum use only. If you are sampling toxic or hazardous gases, the vent
outlet must be connected to a vacuum exhaust vent system designed to safely remove these toxic or
hazardous gases.
If the vent port is blocked or connected to a source of pressure, toxic or hazardous gas could enter
the work area and break the gas cell windows. Never block or plug the vent port or connect it to a
source of pressure.
The pressure relief valve is set to 25 PSI to protect the 2M or 10M gas cell with ZnSe windows. The
relief valve is connected to the vent port.
