4. Disconnect the liquid reagent tubing from the inlet and discharge
of the metering pump.
5. Disconnect the water sample tube from the panel inlet.
6. Disconnect the drain tubing from drip tray outlet.
7. Remove the clamps holding the probe cable, if probe will be
serviced.
8. Remove the four screws holding the panel in the enclosure, and
remove the panel from the enclosure. The panel will hang in front
of the enclosure on strain relief cables.
9. Hold the panel upright while removing it to avoid spilling water
trapped in the cell. Remove mounting screws and set aside before
releasing panel. There is water trapped in the various tubing units
and chemical trapped in the reagent tube units.
5.2.2 Occlusion ring removal and replacement
WARNING:
To avoid possible severe personal injury or equipment
damage, observe the following:
Turn off the flow to the analyser before removing the occlusion ring from the
metering pump. The occlusion ring stops the free flow of liquid through the
analyser sample lines. If it is removed with flow still present at the analyser,
process water will be sprayed from the pump discharge line and from the
cell top. Sprayed process water can create an electrical shock hazard due to
the presence of dangerous voltage powering the impeller and pump motors.
Do not service the metering pump while it is turning, the metering pump has
enough torque to cause severe personal injury if hands are pinched in the
rotating parts. Disconnect the pump motor
POWER
before servicing the pump.
Wear recommended protective eyewear when servicing the wet components
of the analyser, particularly when servicing reagents and reagent lines. The
analyser uses chemicals that can cause severe personal injury by chemical
burns on contact with eyes. Rinse any area of contact immediately. If chemicals
contact eyes, rinse from eyes and seek immediate medical attention.
5.2.2.1 Removal
a. Disconnect power to the wetside of the analyser by disconnecting
the power supply from the SFC electronics.
