If the correct cuvette is installed, and the error is still posted, try rotating the flow through
assembly slightly to improve the connection to the ultrasonic transducer. If this fails to work, the
cuvette may have to be replaced. The detection for this cuvette only operates in
AUTO
mode. If
the system is operating correctly
AUTO
will flash on the display.
The connection can be improved with the use of a small film of an anti-oxidant compound such as
OX-GARD ™ made by GB Electrical Inc. This product is available in the electrical section at most
hardware stores.
Condensation on Cuvette
The Vapor Purge system prevents moisture, due to condensation, from occurring inside the
instrument. To ensure proper performance, the desiccant and seals must be maintained in good
condition. If these are distorted or worn they need to be replaced.
Once the flow through is removed from the instrument, it is possible to have condensate form on
the cuvette. It is not desirable to bring additional moisture into the instrument as this will lower the
desiccant life. For this reason, any condensate should be wiped from the cuvette before
reinstalling the flow through unit.
If condensate forms on the cuvette, use the following procedure:
1. Shut off the flow with the provided ratcheting clamp.
2. Empty the water out of the cuvette to lower the cold mass.
3. If clean warm water is available it can be poured into the cuvette.
4. Dry and clean the exterior of the cuvette.
5. Ensure the cuvette is installed into the flow through tightly.
6. Reinstall the flow through unit.
7. Restart the sample water flow.
Once the flow through assembly is inserted into the instrument, the Vapor Purge system will
prevent further condensate from forming inside of the instrument no matter the outside
environment or the temperature of the sample water.
All seals are important for proper operation and to extend desiccant life. These seals must be in
place and maintained. Replace any missing or distorted seals or worn call Xylem Analytics
Germany (section 6.4) Three important seals that are often overlooked are the O-ring under the
flow head, the orange enclosure seal, and the USB plug cover.
