Installation Series 4060
40 Teledyne Analytical Instruments
Addenda included with this manual to determine if special
conditions apply.
3.3.3.1 EFFLUENT
All the gases introduced into the detection cell vent from one fitting
at the rear of the analyzer. TAI recommends that the cell be permitted to
vent directly to the atmosphere wherever possible.
If a vent line is required, the installation must include a drop-out pot
to collect the water that is formed by the burning of the hydrogen fuel.
The vent line must be constructed so that water and dirt cannot collect in
it.
3.3.3.2 SAMPLE BYPASS VENT
The sample bypassed by the back-pressure regulation system vents
from a separate port at the rear of the analyzer. If a vent line is required,
it must be installed so that water and dirt cannot accumulate in it.
3.3.3.3 FUEL AND AIR CONNECTIONS
The fuel used to provide combustion should be hydrogen gas, zero
quality with certified THC of less than 0.5 ppm and supplied at a
pressure of 40 psig. The compressed air, ultra zero gas quality with
THC less than 0.1 ppm should be used and supplied at a pressure of 40
psig. Connect the fuel and air sources to the instrument according to the
gas connection diagram included at the back of this manual.
3.3.3.4
SAMPLE AND SPAN GAS CONNECTIONS
The sample and span gas connections are made at the rear panel. If
the optional autocal module is installed, the sample and span gas will
connect to this module. If no autocal module is present, these gases
connect to the labeled fittings on the rear panel.
Set the supply pressure for sample and span gas to 20 psig.
3.4 Placing the System in Operation
See Section 4 for information on starting the analyzer for the first
time. Makes sure that all electrical connections have been made
correctly and all connectors are fully seated. Make sure all gas
connections are correct and leak–free.
