Instalation and Startup 2-5
Mechanical Installation
Locate the 3050-AP as close as possible to the sample source. The unit should be protected from
direct exposure to weather and located so that the ambient temperature specifications will not
be exceeded. Refer to Figure 2.2 for connection locations.
1. If not already installed, install a main process shut-off valve and pressure reducer (rec-
ommended) at the sample tap. Refer to figure 2.3.
2. Connect the dryer input to the “to dryer” 1/8-inch compression fitting. Connect the
dryer output to the “from dryer” 1/8-inch compression fitting. Refer to dryer connec-
tion instructions and figure 2.4.
3. Connect the exhaust fitting to appropriate vent system.
Leave “exhaust out” fitting capped or blocked with an isolation valve until
sample gas is flowing. This prevents ingress of wet ambient air. “Sample in” is
protected with internal valve, which is closed when power is off.
4. Open the main process shut-off valve and purge sample line to an appropriate area
for at least five minutes. Close the main process shut-off valve. This will help prevent
contamination from entering the cell.
5. Connect the sample line to the sample inlet 1/8-inch compression fitting.
