Mechanical Installation
Install the 3050-OLV Analyzer 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 specications will not be exceeded (see Figure 2-2
for connection locations).
1. If not already installed, install a main process shut-o valve and pressure
reducer (recommended) at the Sample tap (Figure 2-3).
2. Connect the Dryer input to the “To Dryer” 1/8-inch compression tting on
the analyzer. Connect the Dryer output to the “From Dryer” 1/8-inch com-
pression tting. Refer to “Dryer Installation Instructions” and Figure 2-4.
3. Connect the exhaust tting to appropriate vent system.
Leave “Exhaust Out” tting capped or blocked with an isolation valve
until Sample gas is owing. This prevents ingress of wet ambient air.
“Sample In” is protected with internal valve, which is closed when
power is O.
4. Open the main process shut-o valve and purge sample line to an ap-
propriate area for at least ve (5) minutes. Close the main process shut-o
valve. This will help prevent contamination from entering the sensor.
5. Connect the sample line to the sample inlet 1/8-inch compression tting.
