4.7.2 Installing Reagents and Reagent Level Sensors
Warning.
Some reagents contain hazardous chemicals. Ensure
that safety information is read and understood before
handling reagents.
Wear appropriate protective clothing when handling
reagents.
Care must be taken when installing the reagents to prevent
contamination. Keep the reagent level sensor dry and avoid
handling the stem. Hold the level sensor by clamp ring
Fig. 4.12.
Use the following process for each reagent level sensor and
container combination:
1. Using a dry, lint-free cloth, remove any foreign matter from

level sensor stem
.
2. Remove the reagent container cap and store in a clean,
safe place.
3. Insert the reagent level sensor into the reagent container,
ensuring that all connections are still in place.
4. Check that the end of the level sensor is in close proximity
to the bottom of the reagent container. Adjustment can be

4.7.3 Connecting the Analyzer Waste
Analyzer waste is expelled through the dedicated waste port on
the valve manifold assembly (identified by a 'W' symbol).
Route analyzer waste tubing to an open waste container or
drain in accordance with local regulations.
Caution. Analyzer waste is contaminated with reagents.
Dispose of the waste in accordance with local regulations.
Note. Keep the analyzer waste tubing as short as possible
and route as vertically as possible to allow free drainage.

Ensure no back pressure exists in the waste tubing.
