InstallationW A R N I N GMultiple hazards. Only qualified personnel must conduct the tasks described in this section of thedocument.Mechanical installationD A N G E RRisk of injury or death. Make sure that the wall mounting is able to hold 4 times the weight of theequipment.W A R N I N GPersonal injury hazard.Instruments or components are heavy. Use assistance to install or move.The object is heavy. Make sure that the instrument is securely attached to a wall, table or floor for asafe operation.This instrument is rated for an altitude of 2000 m (6562 ft) maximum. Use of this instrument at analtitude higher than 2000 m can slightly increase the potential for the electrical insulation to breakdown, which can result in an electric shock hazard. The manufacturer recommends that users withconcerns contact technical support.Install the analyzer indoors, in a non-hazardous environment. Refer to the supplied mountingdocumentation.PlumbingD A N G E RFire hazard. This product is not designed for use with flammable liquids.N O T I C EDo not install reagents until all plumbing is complete.Make sure to use the specified tubing size.Sample line guidelinesSelect a good, representative sampling point for the best instrument performance. The sample mustbe representative of the entire system.To prevent erratic readings:• Collect samples from locations that are sufficiently distant from points of chemical additions to theprocess stream.• Make sure that the samples are sufficiently mixed.• Make sure that all chemical reactions are complete.Connect the sample streamInstall each sample line into the center of a larger process pipe to minimize interference from airbubbles or bottom sediment. Figure 3 shows examples of good and bad installation.Keep the sample lines as short as possible to prevent the accumulation of bottom sediment. Thesediment can absorb some of the analyte from the sample and cause low readings. The sedimentcan later release the analyte and cause high readings. This exchange with the sediment also causesa delayed response when the analyte concentration in the sample increases or decreases.8 English
