Installation
3.6.2 Use the sample conditioning kit
Assemble the head height regulator (stand-pipe) and filter as shown in Figure 7 . Make
sure the sample pressure to the sample conditioning is between 1.5 and 75-psig for
proper operation.
1. Set flow by adjusting the ball valve (item 18, in Figure 7 ). The valve is fully closed
when the lever is perpendicular to the valve body and fully open when the lever is
parallel with the valve body.
2. Observe the flow in the unfiltered sample bypass (clear tube, item 13 in
Figure 7 ). Make sure the flow is adjusted so there is always bypass flow.
3. Use the ball valve (item 19) to turn off sample flow to the instrument.
