SETUP AND INSTALL
Mount the Analyzer
The Model 3000TA is for indoor use in a general purpose area. It is NOT for hazardous
environments of any type. It is designed for flush panel mounting. Use the four mounting holes—
one in each corner of the rigid frame to panel mount the instrument.
Gas Connections
Note: Do not remove plastic caps on VCR fittings, unless you are ready to make
connections.
The analyzer is equipped with 1/4 inch tube fittings, and 6 mm adapters are supplied for
metric system installations.
You will need:
•Zero gas — regulated supply of oxygen free gas.
•Span gas — regulated supply of a standard gas typically containing oxygen at 70-
90% of the full scale value on the range of interest.
•Purge gas — oxygen free inert gas for purging if applicable.
•Sample gas — regulated supply of sample gas available to the analyzer.
Make your gas connections to the analyzer as follows:
1. Install the flow restrictor that shipped with your instrument:
•For positive pressure applications, install the restrictor with the blue dot to the
SAMPLE IN port. The small circular orifice should face away from the back of
the unit. Remove the sticker after installing.
•For low pressure applications (less than 5 psig), connect the restrictor without the
blue dot to the SAMPLE IN port.
•For vacuum service (5-10 in Hg), install the restrictor without the blue dot to the
EXHAUST port.
2. Connect your sample gas to the SAMPLE IN port.
3. Connect a vent line to EXHAUST OUT port.

4. If using remote calibration feature:
•Connect zero gas to the ZERO IN port.
•Connect span gas to the SPAN IN port.
5. Otherwise, calibration gases must be Tee'd into the sample inlet with appropriate
valves.
6. Regulate the sample gas pressure between 2 and 50 psig sufficient to keep the front
panel flowmeter reading in an acceptable range (0.1 to 2.4 SLPM). For non-
pressurized sample or very low pressure, (less than 2 psig) vacuum service plumbing
is recommended.
7. If greater sample flow is required for improved response time, install a bypass in the
sampling system upstream of the analyzer input.
8. For optional vacuum application where the sample pressure is at atmospheric or very
low pressure, the instrument should be fitted with the vacuum service option. This
option locates the flow control valve on the exhaust side of the Micro-fuel Cell.
Note: Exhaust connections must be consistent with the hazard level of the constituent
gases. Check Local, State, and Federal laws, and ensure that the exhaust
stream vents to an appropriately controlled area, if required.

Install the Micro-fuel Cell
The Model 3000TA is designed to accept the L2C Micro-fuel Cell or as an option, it can use
the B2 series of Micro-fuel Cells by incorporating a spacer adaptor (Teledyne P/N B66378).
L2C Micro-fuel Cell
1. Remove power from the instrument.
2. Remove the old sensor (if installed).
Discard in accordance with all
Federal, State, Local or other
regulations which may apply.
3. Purge the analyzer at approximately 1
SCFH flow rate with nitrogen (or
applicable sample gas with the sensor
holder removed).
4. Remove the new sensor from its
double bag storage.
5. Remove the sensor shorting button.
6. Place the sensor inside the cell block.
7. Place the sensor on the sensor holder
so that the gold contact plate of the
sensor is facing upwards.
8. Install the sensor and sensor holder into the cell block.

9. With the O-ring in place, align the guide pin with the hole on the cell holder. Then,
with the holder, lift cell into the cell block.
10. Push the gate on the cell block down so that the slots on the side of the gate engage
the locating screws on the side of the block. This forces the holder into position and
forms a gas-tight seal.
11. Purge the system using sample or zero gas.
12. Power the system back up.
If the installation is carried out quickly enough, the sensor will reach a stable low value less
than 1 ppm in approximately 8 hours or less.
