thecontractorortheengineermaybesubstitutedforthe
factorygrommets,andshouldbeusedwherefactory
grommetsarenotprovided.
VerticalunitmodelsFHY,FSY,orFXYaredesignedtobe
oormountedorotherwisesupportedfrombelow,and
boltedtothewallstructurethroughthemountingholes
providedinthechassis.Theseunitsmaybewallhungonly
whenoriginallyorderedfromthefactoryforwall-mount
applications.Hi-PerformanceverticalclosetunitsVEY
aredesignedtobeoormountedorotherwisesupported
frombelowandmaybeanchoreddirectlythroughthe
cabinetoorortheoptional6-inchlegs.
Thetypeofmountingdeviceisamatterofchoice,however
themountingpointshouldalwaysbethatprovidedin
thechassis,plenum,orcabinet.Refertotheunitproduct
drawingsformountingholelocationsandsizes.
Aftermountingtheunit,itisthenreadyforthevarious
serviceconnectionssuchaswater,drainandelectrical.
Atthistime,itshouldbeveriedthatthepropertypesof
servicesareactuallyprovidedtotheunit.Onthoseunits
requiringchilledwaterand/orhotwater,theproperline
sizeandwatertemperatureshouldbeavailabletotheunit.
Inthecaseofrefrigerantcooling,theproperlinesize
andrefrigeranttypeshouldbeavailabletotheunit.On
unitswithsteam-heatingcoils,theproperlinesizing
androutingshouldbeveried,andthemaximumsteam
pressureappliedtotheunitshouldneverexceed10psig.
Thedrainpipingandsteamtrapshouldbesizedand
routedtoallowforpropercondensateow.
Theelectricalservicetotheunitshouldbecomparedto
theunitnameplatetoverifycompatibility.Theroutingand
sizingofallpiping,andthetypeandsizingofallwiring
andotherelectricalcomponentssuchascircuitbreakers,
disconnectswitches,etc.shouldbedeterminedbythe
individualjobrequirements.Verifytheelectricalconductor
sizeissuitableforthedistancetotheequipment
connectionandwillsupporttheequipmentelectricalload.
Allinstallationsshouldbemadeincompliancewithall
governingcodesandordinances.Compliance with all
codes is the responsibility of the installing contractor.
Oncertainunits,shippingscrewsorbracesmustbe
removedaftertheunitisinstalled.Besuretocheckalltags
ontheunittodeterminewhich,ifany,ofthesedevices
needtoberemoved.
