3. Allow the analyzer to warm up until the instrument stabilizes.
4. Adjust the flow rates.
5. Turn on sample to the instrument.
6. If necessary, calibrate the analyzer
The analyzer includes an interlock system that prevents the injection valve
from operating until the pyrolyzer and oven temperatures reach the operating
value.
Follow this procedure when temporarily shutting down the analyzer. To shut
down the analyzer for maintenance purposes or for a long-term shutdown,
refer to the following section
1. Turn the solenoid manifold regulator to 0 psig. Doing so blocks sample
flow to the injection valve and purges sample from the injection valve.
2. Observe reported sulfur value.
3. Do not interrupt power, instrument air, carrier or auxiliary air, or open
oven doors until reported sulfur value is less than 0.5 ppm or reported
sulfur value has not changed by more than 2% for 15 minutes.
Note Sample is purged automatically by 3-way diverter valves when power is
removed from the instrument.
The analyzer system must be fully shut down and the sample system
decontaminated as appropriate PRIOR to performing maintenance. Follow this
procedure when shutting down the analyzer for maintenance or a long-term
outage.
1. Close the sample flow to the instrument and purge sample from the unit
using air.
2. Turn off power to the analyzer.
