2. Support gases for the instrument should be located near the analyzer.
A uniform temperature environment for cylinders and regulators is es-
sential in order to keep constant pressure and flow rate. Always keep gas
containers inside the building where temperature fluctuations are at a
minimum.
3. Have adequate ventilation around the instrument area without any
high flow velocity draft directly onto the analyzer. Be sure not to block
any vent slots in the rear or top of the analyzer since limited air circulation
will cause overheating and poor performance.
4. An external FID H2 Shut-Off valve should be installed on the hydrogen
line. The recommend valve is a UHP stainless steel diaphragm normally
closed valve that can be actuated at the Carrier gas pressure. Periodically
check that the shut-off valve operates correctly when the FID flame goes
out.
5. Gas Purifiers for support gases should be installed within 20-30 feet (6-9
Meters) or less from the analyzer. This minimizes tubing length and the
amount of impurities picked up from the lines.
6. All connections to the instrument should be made with 1/16th inch
stainless steel tubing (maximum 0.030” ID). Coil some extra 1/16th inch
gas lines behind the analyzer. This allows for flexibility when moving or
turning the instrument for service and routine maintenance.
7. Situate the ta3000F in such a way that there is always access to the rear
panel for easy hook up of the gases, as well as ease of service components.
Allow approximately 30 inches service clearance at the rear of the instru-
ment.
Electrical Preparations and Connections
Always verify that the voltage on the label located on the rear of the
instrument matches the supplied power before connecting.
1. The electrical requirements for the ta3000F Gas Analyzer can be 100,
115, 220, or 240 VAC, and 50 or 60 Hz, depending on the voltage option
ordered. AC power must be free from cyclic RMS voltage variations,
spikes or drops greater than 1.5%. A minimum of 5 amperes current must
be available.
2. Good grounding of the AC power circuit is required, verify proper
receptacle grounding before connecting the instrument.
