Valves and Piping
Noformalmaintenanceisrequiredonthevalve-package
componentsmostcommonlyusedwithfancoilunitsother
thanavisualinspectionforpossibleleaksinthecourse
ofothernormalperiodicmaintenance.Intheeventthat
avalveshouldneedreplacement,thesameprecautions
takenduringtheinitialinstallationtoprotectthevalve
packagefromexcessiveheatshouldalsobeusedduring
replacement.
Filters, Throwaway
Thetypeofthrowawayltermostcommonlyusedonfan
coilunitsshouldbereplacedonaregularbasis.Thetime
intervalbetweeneachreplacementshouldbeestablished
basedonregularinspectionofthelter,andshouldbe
recordedinthelogforeachunit.Refertotheproduct
catalogfortherecommendedltersizeforeachproduct
typeandsize.Ifthereplacementltersarenotpurchased
fromthefactory,theltersusedshouldbethesametype
andsizeasthosefurnishedfrom,orrecommendedbythe
factory.Pleatedmedia,orextendedsurfaceltersshould
notbeusedsincethehighairpressuredropsencountered
withthesetypesofltersisnotcompatiblewiththetype
offancoilunitcoveredinthismanual.Consultthefactory
forapplicationsusingltertypesotherthanthefactory
standardoroptionalproduct.
Filters, Permanent
Amaintenancescheduleforpermanentltersshould
bedevelopedinthesamemannerasthrowawaylters.
Unlikethrowawaylters,permanentltersmaybe
cleanedandre-installedintheunitinsteadofbeing
discardedwhendirty.Theoptionalfactorypermanent
ltermaybecleanedinhotsoapywatertoremoveany
trappeddirt.Itshouldthenbesetasideonedgetodry.
Beforereplacingthelterintheunit,itshouldbe
rechargedwithsometypeofentrapmentlmsuchas
“Film-CorRechargingOil.”Theltershouldbesprayedon
bothsidesorsubmergedinthelmtoassurecomplete
coverage.Theltershouldnotbeallowedtosoakinthe
lm,butshouldbeimmediatelyremovedandtheexcess
lmdrainedfromthelterbeforere-installationintheunit.
Consultalocalltersupplierfortypesofavailablecleaning
solutionsandcharginglms.
Itshouldbenotedthatpermanentltersnormallyhave
lessstaticpressurelossthanthrowawaylters.
Drain
Thedrainshouldbecheckedbeforeinitialstart-up,andat
thebeginningofeachcoolingseasontoassurethatthe
drain,draintrap,andlineareclear.Ifitisclogged,steps
shouldbetakentoclearthedebrissothatcondensatewill
oweasily.
Periodicchecksofthedrainshouldbemadeduringthe
coolingseasontomaintainafree-owingcondensate.
Unitsprovidedwithasecondaryor“tell-tale”drain
connectionwillindicateacloggedmain-drainlinebyow
fromthe“tell-tale”connection.
Shouldthegrowthofalgaeand/orbacteriabeaconcern,
consultanairconditioningandrefrigerationsupply
organizationfamiliarwithlocalconditionsforchemicals,or
othersolutionsavailabletocontroltheseagents.
Replacement Parts
Factoryreplacementpartsshouldbeusedwherever
possibletomaintainunitperformance,it’snormal
operatingcharacteristics,andthetestingagencylistings.
