INSTALLATION AND START-UP
Incoming sample temperature 0 °C and 100 °C
Optimum input gas temperature 60 °C ± 5 °C
Minimum input pressure 6 PSIG
Maximum pressure 50 PSIG
Wiring 22 gauge twisted/shielded pair
Sample Input Tubing ¼” OD, electropolished 316L VAR SS
Make sure power is off before you begin installation.
Rear Panel Connections:
1. Remove terminal cover to access interface board.
2. Install main process shut-off valve and pressure regulator at sample tap.
Gas Connections:
1. Remove VCR plugs and gaskets from sample inlet fi tting and exhaust fi tting and con-
nect sample input tube and exhaust tube. Vent exhaust to vent system.
2. Connect instrument air supply to instrument air fi tting.
3. Select 120 or 240VAC on voltage selector. Mark operating voltage on rear panel.
Electrical Connections:
1. Make sure the installed power cord has an approved terminator plug per NEC and CEC
regulations.
2. Wire the analyzer per requirements for non-hazardous location per instructions in
Chapter 3 of the manual.
Communications Connections:
1. Connect 4-to-20 mA analog output and alarm/data valid terminals on interface board
to analyzer using metallic signal conduit.
2. Connect the RS-232 or RS-485 serial communications to analyzer. RS-485 connection
shares same cable and metallic signal conduit as analog output and alarm/data valid
contacts.
3. RS-485 Communications: RS-485 terminator switch is turned to “ON,” only if your unit
is a dedicated analyzer or if it is the last analyzer in a chain of multiple analyzers.
Replace all analyzer covers before continuing.
Initial Startup:
1. Open the main shutoff valve at the source.
2. Turn on the AC power at the source.
3. Once the sample fl ow starts, the analyzer will be in normal operating mode. Allow
analyzer to warm up for 45 minutes.
Dry Down:
Allow 5 to 7 days for the analyzer to dry down and stabilize. At end of dry down period,
concentration value on display will be stable and recorded data will level off . Zero alarms
will still be on the display. See Chapter 3 in the manual for more details on dry down and
information on shortening the dry-down process.

ANALYZER PARAMETERS
Zero Cycle:
Perform a zero cycle aft er the dry down.
Press Zero key and then the #8 key (arrow down) until you see “Zero.” Press the Enter key to select.
Zero cycle takes approximately 2 hours. When zero cycle is complete, the analyzer will adjust the zero off set and automatically return to normal sampling.
