It connects to the accessory junction splitter.
6 Secure the cables so that cable junctions are not bearing their weight.
Note: The heated intake tube is not flexible. Do not bend it.
Intake Tube Dimensions
Determine the total length of intake tube used in your system. Insulated Intake Tube
Specifications on page A-5 shows the total length of the insulated intake tube. If you
shorten the tube, recalculate the total length.
Installing the 2-micron Dust Filter
The dust filter (part number 9972-073) is a Swagelok® 2-micron filter that will
reduce the amount of dust that enters the gas analyzer optical cell. Under normal
conditions, the filter should extend the amount of time that can pass before you
need to clean the optical cell. Use the filter in environments that have airborne dust
and pollen that can contaminate the optical cell.
Important: The filter does not completely eliminate the need to regularly clean
the optics. Regular cleaning is required in order to prevent measurement drift
that can occur when certain kinds of contaminants accumulate on the cell win-
dows.
l
The filter will increase the power requirements of your system. As the filter
becomes dirty, the flow module will use more power to maintain the same flow
rate.
l
The filter may affect H
2
O frequency response, especially when it is dirty. (This
can be addressed with additional frequency response corrections.)
l
The effectiveness of the filter depends upon the site conditions, overall level of
dust in the air, and the characteristics of the dust (fine vs. coarse dust particles).
The dust filter includes:
l
Swagelok filter with two compression fittings.
l
Two inch (5.08 cm) by ¼ inch stainless steel intake tube extension.
The dust filter installs between the end of the intake tube and the intake cap. To
install it:
