atmosphere.If located inside a building,a vent is required.The accumulation of halogens or other vapors is not permitted in this area.a0008101Fig.2:Dimensions663(26.10)610(24.00)572(22.50)558.9(22.00)529.7(20.85)508(20.00)365.4(14.39)369.2(14.54)?9.53(.375)305(12.00)841.9(33.14)802(31.57)762(30.00)mm(inch)EZ-TOC II analyzer

CA52TOC10Endress+Hauser3.3Installation instructions3.3.1MountingThe analyzer has four mounting holes in the back of the cabinet.Use at least 10 mm(5/16)mounting hardware to support the unit,as it is heavy.The mounting feet on the back of the analyzer provide clearance between the wall and the cabinet.3.3.2Installing the UV lampCaution!The UV lamp is extremely fragile.Perform installation with care.a0011122Fig.5:UV reactorPreparation 1.Open the cabinet door and swing out the analyzers front panel.Block the door and panel,so that they will not swing back.2.Remove the top Phillips screw on the reactor ground strap(pos.1,Fig.5).3.Remove the Phillips screw above the ground strap(pos.2,Fig.5).4.Remove the reactor cap.5.Remove the top of the reactor shell.12EZ-TOC II analyzer CA52TOCInstallationEndress+Hauser11Installing the lamp1.Inside the reactor,remove the reactor nut and the two O-rings beneath it.2.Carefully slide first the reactor nut,then the two O-rings,over the glass end of the UV lamp to the top of the lamp.3.Insert the lamp into the center of the reactor.Exert a gentle downward pressure on the lamp as you tighten the reactor nut.The lamps metal sleeve must be against the nut.4.Caution!Tighten with care.Undertightening the reactor nut can result in leakage,causing damage to the analyzer.Overtightening the reactor nut can break the outer casing of the UV lamp.Hand-tighten the reactor nut,and then tighten it by one additional half turn.5.Replace the top,cap and ground strap on the reactor shell.3.3.3Connecting the gas sources Gas and liquid connections are all made via the connection panel located in the lower right-hand side of the cabinet.a0010722Fig.6:Connection panel for gas and liquid connectionsAll connections are made using PFA or Kynar fittings.Tighten the fittings securely,but be careful to avoid overtightening the fittings,as you may destroy the threads.CalibrationDeionizedWaterCleanDilutionSampleManualPersulfateSodiumAcidSample InSample OutDrainPurgeVentIR VentAir InSolution30 psiMax.Pressure2 BarsInstallationEZ-TOC II analyzer CA52TOC12Endress+Hauser3.3.4Connecting the mediumConnecting the air supply:1.Use PFA tubing to attach the air supply line to the Air In fitting.2.Tighten the fittings securely.Caution!Do not under any circumstances allow the air pressure entering the analyzer to exceed 2 bar(30 psi)maximum,as this could damage the analyzer and result in personal injury.3.Turn on the air supply.4.Use a mixture of water and soap to check for leaks.Paint the mixture directly onto the connections at the analyzer and the air supply.If there is a leak,bubbles will form around the connection.Tighten the fitting a little more and recheck the connection.Do not overtighten the fittings or you may destroy the threads.Connection of the liquid medium:1.Place the medium bottles close to the analyzer.2.Pour the reagents(acid,persulfate)into the two 5.5 US gal bottles.Pour the cleaning,calibration and DI solutions into the three 2 US gal bottles.Use the bottle caps with a hole(included in the delivery)during operation of the analyzer.Use the bottle caps without a hole for transport and storage.3.Cut five pieces of 1/8 PFA tubing long enough to reach the bottom of the medium bottles and the medium connections of the connection panel.4.Pass the ends of the tubes through the holes in the bottle caps to the bottom of the bottles.5.Connect the other ends of the tubes to the corresponding fittings on the connection panel.EZ-TOC II analyzer CA52TOCInstallationEndress+Hauser133.3.5Preparing chemicals#Warning!Accidents with chemicals can kill,blind,burn,or damage lungs.Many chemicals are poisonous or corrosive;some are explosive,by themselves or in combination.Others are hazardous because they can be absorbed easily through skin or the respiratory system.When working with any chemicals,always observe the precautions in the section Precautions regarding use of chemicals.Precautions regarding use of chemicals Read the material safety data sheets(MSDS)provided with each chemical to see what hazards are present and what precautions you must take.If you are not sure of the risks,seek assistance from qualified individuals.Never prepare chemicals by yourself.If an accident happens,you may need help.Make sure someone else is nearby.Prepare chemicals only in a properly-equipped lab facility.Always wear goggles,rubber gloves and a rubber apron when preparing chemicals.If you work with finely powdered chemicals,wear a protective face mask or respirator.Never breathe,taste,or swallow any chemical or solution used with the EZ-TOC II analyzer(or any other process analytical device).When solutions are prepared,always label containers with contents and date of preparation.Dispose of unlabeled or expired solutions in accordance with local regulations.Some chemicals react violently when combined or dissolved in water,causing explosions,fire,heat,or the dangerous discharge of gases,foam or spray.Avoid the risk of a serious accident;if you do not know how certain chemicals will react,do not combine them.Never combine chemicals known to react very strongly.There are three chemical solutions normally used with the EZ-TOC II.They are:Phosphoric acid,H3PO4,10%(v/v)solutionIt is used to acidify the sample solution.This transforms carbonate ion(CO3=)to CO2 and elimi
