UNPACKING



ConnecttheintakefiltertotheAirInportasshownbelow.UseTeflontapeonfilter

threadifnotsuppliedonthefitting.



POWER



TheZAGiselectricallyconfiguredforonevoltageandfrequency.Theseelectrical

parametersarespecifiedbytheuserwhenorderingthemodel7000.Connectthe

systemto110‐12060Hz,220‐240VAC50Hzor60Hz,dependingupontheelectrical

configurationofthesystem.



OPERATION



Powerthesystemon,adjustthepressureto25‐30PSIG(orlower)andregulatethe

outputflowforapproximately5‐15LPM.Thepressurewilltakeapproximatelyone

minutetoreachtheregulatedpressureafterthepowerswitchisactivated.Thesystem

mustburninforapproximately24hourstoproducedrygas.Whenoperatingthe7000

undernormalconditions,thesystemwillproduceupto20LPMflowat25PSI,15LPM

for220VACsystems.TheATMdewpointofthegaswillbeashighas‐10oCat20LPM

flow.Connectalinetothedrainportandroutetoawatercollectioncontainer.

Dependinguponambienthumidity,waterwillexitthisportviathecoalescingfilter.



IMPORTANT:duringinstallation,donotblockthecoolingventsonthetopfrontofthe

cover.Theseventsexhausttheheatdissipatedbytheinternalcomponents.



NOTE:Thefirststageoutputregulatorissetfor35PSIG.Thisregulatorismounted

internallybehindthefrontpanel.Donotexceedasettingof30PSIGonthefront

panelmountedregulatorfornormaloperation.

ADJUSTINGTHEOPTIONALCATALYTICCONVERTERTEMPERATURE



Thesystemisshippedwithasettingof300oC.Theconvertercanbeadjustedashighas

550oC(482oCfor240VACsystems)forimprovedefficiency.



1.PressandholdthePUSHTOSETbuttononthefrontpaneltemperature

controller.

2.Turntheknobclockwisetoincreasethetemperaturesetting.



DEWPOINTINDICATOR



AcolorchangedewpointindicatorisnowstandardonallEnvironicsZAGs.This

indicatorenablestheusertodeterminethedrynessoftheair.Thedewpointindicator

islocatedintheupperrightcornerofthefrontpanel.Whenthepneumatictoggle

switchison,lessthan1LPMofair,fromtheZAG,flowsthroughtheindicator,exiting

fromasmallholeinthefront.Thecoloroftheindicatorislightgreenwhentheairis

driest.Itturnsfromlightgreentolightyellowwhenthedewpointrisesabove

approximately‐10oC.Athigherdewpoints,thecolorchangestowhiteatitswettest.

WhentheZAGisnotbeingused,switchthepneumaticswitchoff.Thiswillpreventa

flowdrawontheZAGwhichwillresultintheZAGpumpturningonandofftoreplenish

whatislostthroughthedewpointindicator.Oncethesignificantcolorchangehas

occurredandaproblemhasbeendiagnosedandfixed,itwilltakeapproximately1hour

forthecolortochangebacktogreen.
