Ametek 3050-DO

PN 305725901, Rev YF
Mechanical Installation
Install the 3050-DO Analyzer as close as possible to the sample source. The
unit should be protected from direct exposure to weather and sunlight, and
located so that the ambient temperature specications will not be exceeded.
1. If not already installed, install a main process shut-o valve at the Sample
tap. Refer to Figure 2-3.
2. Install the 3050-DO Analyzer in its selected location and bolt in place. Refer
to Figure 2-2.
3. Connect instrument air to 1/4-inch tube tting. Maximum input 100 PSIG.
Refer to Figure 2-1. Set the Pilot Valve to 80–100 PSIG.
4. Connect an appropriate vent tube/system to the 1/8-inch Sample Out t-
ting on the analyzer.
5. Optional Heated Pressure Reducer:
If the Heated Pressure Reducer was purchased, connect its 1/4-inch relief
out and vapor bypass tube ttings to appropriate vent tube/system. Refer
to Figure 2-4.2.
6. Open the main process shut-o valve and purge entire length of sample
line (up to the analyzer) to an appropriate area for at least ve (5) minutes.
Close the main process shut-o valve. This will help prevent contamination
from entering the Cell.
7. Connect the sample line to the 1/8-inch Sample In tting.
Make this connection immediately after the purge has completed.
8. Reinspect the process line connections and ensure that all are connected
to the proper external supply, exhaust, and drain tubing, to ensure the
hazardous process gas will not be released into the atmosphere.
Dierential pressure between Inlet and Outlet must be at least 20
PSIG.
9. Open the main process shut-o valve.
10. Prior to applying power to the analyzer, open the valve to the Dryer 1/4 to
1/2 turn.
