Start up the system unit
Connect all the modules of the system to a power strip. Do not set the pump to on until the
instrument is ready to operate.
1. Set the power strip to on. Then set each individual module switch to on.
Note: A 6-second delay occurs from the power circuits for the instrument to start up. At this time, a beeping
sound is audible.
The sampler automatically completes an operation check. The probe moves over the wash bath
or directly above the wash reservoir. When the sampler is initialized through the sampler
configuration screen or when a run is started, the probe goes in the wash reservoir.
2. Look through the side panel on the system unit to see if the lamp is on. The lamp comes on in
about one minute. The delay lengthens for the life span of the lamp. The heater controllers shows
the current temperature of the blocks.
3. Start the software to make sure that the software is connected to the system unit. A dialog box
shows 'Connecting to System unit(s)'. If the setup was done, the dialog box goes away.
Note: If the connection is not made correctly, a dialog box shows a message that system unit A is not found.
Make the connections and click OK.
Prepare the instrument for analysis
When the system start up is done, prepare the instrument for analysis. Refer to
unit on page 10.
1. Make sure to use a special detector for the analysis. A photometric detector module is necessary
for most QuikChem methods.
Note: The Ion Chromatography (IC) channel (optional) typically uses a conductivity module instead of a
photometric detector module.
2. Install the manifold on the channel that will do the analysis. For the manifold installation, refer to
the installation manual.
3. Make all the injection valve fluidic connections. Refer to
4. Make all the flow cell fluidic connections to the detector.
