Incorrect installaon may void warranty.
NOTE: All piping and electrical connecons should be inspected prior to installaon to ensure they have maintained
their integrity during shipping and locang the dryer.
First,maketheinialconneconsasfollows:
1. Inletpipingincludinganisolaonvalve
2. Outletpipingincludinganisolaonvalve
3. Coalescingpre-lterandparculatepost-lter
Werecommendthedryerbeinstalledwitha0.01micronCLEARPOINT®coalescingpre-lterattheinlet
anda1.0micronCLEARPOINT®parculatepost-lterattheoutlet.Itisrecommendedtoinstallboth
5.0micronand1.0micronltersupstreamofthedryerinordertomaintaintheoperaonallifespanof
theinletltertothedryer.Inaddion,werecommendtheuseofaBEKOMAT®zeroairlossdrainonthe
pre-lterandatallothercondensatecolleconpoints,especiallythoseupstreamofthedryer.
Locatethecoalescingpre-lterasclosetothedryeraspossiblewhilesllmaintainingsucientspaceforroune
maintenanceandservice.Inletairenteringthedryermustpassthroughacoalescingpre-lterinorderremove
entrainedcondensateandoiltopreventfoulingofthedesiccantandmaintainstandardoperaon.Anyliquid
condensateenteringthedesiccantbedwillleadtooverloadingofthedryer,poordewpointperformanceandrapid
deterioraonofthedesiccantmaterial.Anyoilenteringthedesiccantbedmaypermanentlyreducethecapacityofthe
desiccantmaterial.
Desiccantdusttravelingdownstreamofthedryermaycausecontaminaonand/oracceleratedweartoother
componentsandequipment.Therefore,aparculatepost-ltershouldbeprovidedtopreventdesiccantdustfrom
travelingdownstream.Acvatedaluminaisconsideredanuisancedustandproperprecauonsshouldbetakenwhen
handlingdesiccant(refertoapplicableMSDSsheet).
4. IMPORTANT!Bypasspipingisnecessary.Onlybubbleghtvalvesshouldbeused.
5. Maketherequiredelectricalconnecons;pleasereferthetypeplateofyourdryer.Theenduseris
responsibleforprovidingshortcircuitproteconforthedryer.
6. Pointsofaccessshouldbeprovidedupstreamanddownstreamofthedryerforperiodicmonitoring
ofdewpoint,pressureandtemperaturepriortonalizingtheinstallaon.Takingperiodicdew
pointmeasurementsjustdownstreamofthedryergivesthebestindicaonofwhetherthedryer
isperformingopmally.WerecommendusingMETPOINT®instrumentaontoensureaccurate
measurements.
7. Allpipingmustbeadequatelysupportedandatleastofequalsizetothedryerconnecons.

We recommend the dryer be installed with a 0.01 micron CLEARPOINT® coalescing pre-lter at the
inlet and a 1 micron CLEARPOINT® parculate post-lter at the outlet. It is recommended to install
both 5 micron and 1 micron lters upstream of the dryer in order to maintain the operaonal lifespan
of the inlet lter.

dryer(voltage,frequency,airpressure,airtemperature,ambienttemperature,etc.).Thisisnotthesameas
theASMEUWplateonthevesselsandmaybelowerthanwhatisstampedontheASMEUWplate.
Beforedelivery,eachdryerissubmiedtoaccuratetestssimulangrealoperangcondions.Nevertheless,theunit
couldbedamagedduringtransportaon.Therefore,wesuggestcheckingtheintegrityofthedryeruponarrival(see
page4)andobservingthedryerduringthersthoursofoperaon.
Thestart-upmustbeperformedbyqualiedpersonnelonly.Itismandatorythatthequaliedperson
inchargewillverifysafeoperaonalcondionscomplyingwiththelocalsafetyandaccidentprevenon
requirements.

dryeratapressurehigherthanthemaximumrangcouldbedangerousforboththeoperatorandthe
machine.
Theinletairtemperatureandairowrateenteringthedryermustbewithinthelimitsindicatedonthedataplate.
Installaonprecauonsmustbetakeninordertolimitthevibraonthatcanoccurduringtheoperaonofthedryer.
Therefore,werecommendusingexibleconnecngpipesthatareabletoinsulatethedryerfrompossiblevibraons
originangfromthepipeline.
Theconnecontothemainpoweristobecarriedoutbyqualiedpersonnel,andthesafetyprotocolmust
complywithlocalrulesandlaws.
