3-1 SIMPLIFIED STARTUP AND OPERATION
PROCEDURE
1. Install System Enclosure(s), intercon-
necting sample line, user supplied zero
and span gas cylinders with Rose-
mount supplied dual stage regulators,
conduit, and electrical cables per instal-
lation instructions.
2. Connect 115 VAC 60 Hz single phase
power to appropriate terminals as re-
quired. Turn on user supplied main
disconnect and circuit breaker.
3. Apply power to temperature control
system for probe box. Apply power to
Thermoelectric Cooler. Allow box to
stabilize at operating temperature prior
to introducing sample.
4. Verify that analyzer ranges and analog
outputs are configured as desired.
Apply power to analyzer (if not all ready
powered).
5. Introduce zero gas locally to analyzer
as it is warming to operating tempera-
ture. Calibrate analyzer as recom-
mended using valves integral to
analyzer. Allow 12-24 hours for ana-
lyzer reading to stabilize.
6. Verify that Thermoelectric cooler is op-
erating properly prior to starting sample
pump. Verify that all remote/local
switches are in Remote mode. Adjust
perma pure purge air flow for 3-4 li-
ter/minute on FI

. Allow sample to flow
by applying power to sample pump (if
not all ready powered.) Sample sys-
tem will provide 1-2 liter/minute sample
flow at 8-12 psig. If more sample is
used, then dewpoint of sample will not
be low enough to prevent condensation
in minimum ambient conditions.
7. System should now be analyzing sam-
ple. Table 3-1 lists typical settings for
various components.
