INSTALLATION AND START-UP
Incoming sample temperature 0 °C and 100 °C
Optimum input gas temperature 60 °C ± 5 °C
Minimum input pressure 20 PSIG
Maximum pressure 50 PSIG
Wiring 22 gauge twisted/shielded pair
Sample Input Tubing 1/8” 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 caps from sample inlet fitting and exhaust fitting and connect
sample input tube and exhaust tube. Vent exhaust to vent system.
2. 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 hazardous or 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 inter-
face 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 flow starts, the analyzer will be in normal operating mode.
Allow analyzer to warm up for 45 minutes.
Dry Down:
Allow 1 to 3 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.

ANALYZER PARAMETERS
Verify Cycle:
We do not recommend performing a verify cycle during initial startup. The analyzer and its internal generator should be allowed to equilibrate for at
least 24 hours before you run a verify cycle.
Press the Verify key and the #8 key (arrow down) until you see “Verify.” Press the Enter key to select. The verify cycle takes about 30 minutes.
When the verify cycle is complete, the analyzer adjusts the span and automatically returns to normal sampling.
