Installation and Setup
Setup Procedure
2-6 43iQ Instruction Manual Thermo Scientific
Use the following procedure to setup the instrument:
1. Connect the sample line to the SAMPLE bulkhead on the rear panel
( Figure 2–5 ). Ensure that the sample line is not contaminated by dirty,
wet, or incompatible materials. All tubing should be constructed of
PTFE, 316 stainless steel, borosilicate glass, or similar tubing with an
OD of 1/4-inch and a minimum ID of 1/8-inch. The length of the
tubing should be less than 10 feet.
Note
Gas must be delivered to the instrument free of particulates. It may
be necessary to use the PTFE particulate filter as described in “ PTFE
Particulate Filter ” on page 9-23 .
▲
Note
If the sample may contain particulates larger than 5 microns, it
should be filtered before introducing it to the instrument. Use a filter (such
as PTFE) that does not interact with SO
2
in the sample. If a sample filter is
used, all calibrations and span checks must be performed through the filter.
The filter element should be replaced regularly to prevent the absorption of
SO
2
by trapped material on the filter.
▲
Note
Gas must be delivered to the instrument at atmospheric pressure. It
may be necessary to use an atmospheric bypass plumbing arrangement as
shown in Figure 2–6 if gas pressure is greater than atmospheric pressure.

2. Connect the EXHAUST bulkhead to a suitable vent. The exhaust line
should be 1/4-inch OD with a minimum ID of 1/8-inch. The length of
the exhaust line should be less than 10 feet. Verify that there is no
restriction in this line.
3. If the optional zero/span solenoid valves are installed, connect a source
of SO
2
and HC free air to the ZERO IN bulkhead, and connect a
source of SO
2
span gas to the SPAN bulkhead.
4. Connect a suitable recording device to the rear panel connector. For
detailed information about connecting to the instrument, refer to:
“ Connecting External Devices ” on page 9-1
Communications > “ Analog I/O ” on page 3-82 , and “ Digital I/O ”
on page 3-83 .
