Installation Precautions
Toreducetheriskofseriousinjuryordeath,thefollowinginstallation
precautionsmustbefollowed.
● Wheninstallingtheunitinto…
◦ Awall:Makesurethewallisstrongenoughtoholdtheunit’sweight.Itmaybenecessaryto
constructastrongwoodormetalframetoprovideaddedsupport.
◦ Aroom:Properlyinsulateanyrefrigeranttubingruninsidearoomtoprevent“sweating”thatcan
causedrippingandwaterdamagetowallandoors.
◦ Damporunevenareas:Usearaisedconcretepadorconcreteblockstoprovideasolid,level
foundationfortheunittopreventwaterdamageandabnormalvibration.
◦ Anareawithhighwinds:Securelyanchortheoutdoorunitdownwithboltsandametalframe.
Provideasuitablewindbafe.
◦ Asnowyarea:Installtheoutdoorunitonaraisedplatformthatishigherthandriftingsnow.
Providesnowprotectionhood.
● Iftheremotesensorsarenotusedwiththiscontroller,thendonotinstallthiscontroller…
◦ inaroomwherethereisnothermostat.
◦ wheretheunitisexposedtodirectsunshineordirectlight.
◦ wheretheunitisincloseproximitytoaheatsource.
◦ wherehot/coldairfromtheoutdoors,oradraftfromelsewhere(suchasairvents,diffusersor
grilles)canaffectaircirculation.
◦ inareaswithpooraircirculationandventilation.
● Donotinstalltheunitinthefollowingplaces.Doingsocanresultinanexplosion,re,deformation,
corrosion,orproductfailure.
◦ Explosiveorammableatmosphere.
◦ Wherere,oil,steam,orpowdercandirectlyentertheunit,suchasincloseproximityordirectly
aboveakitchenstove.
◦ Whereoil(includingmachineryoil)maybepresent.
◦ Wherecorrosivegasessuchaschlorine,bromine,orsuldecanaccumulate,suchasnearahot
tuborhotspring.
◦ Wheredense,salt-ladenairowisheavy,suchasincoastalregions.
◦ Wheretheairqualityisofhighacidity.
◦ Whereharmfulgasescanbegeneratedfromdecomposition.
● Donotpositionthecondensatepipefortheindoorunitnearanysanitarysewerswherecorrosive
gasesmaybepresent.Ifyoudo,toxicgasescanseepintobreathableairspacesandcancause
respiratoryinjuries.Ifthecondensatepipeisinstalledincorrectly,waterleakageanddamagetothe
ceiling,oor,furniture,orotherpossessionsmayresult.Ifcondensatepipingbecomesclogged,
moisturecanbackupandcandripfromtheindoorunit.Donotinstalltheindoorunitwheresuch
drippingcancausemoisturedamageorunevenlocations:Usearaisedconcretepadorconcrete
blockstoprovideasolid,levelfoundationfortheunittopreventwaterdamageandabnormal
vibration.
● Beforeperforminganybrazingwork,besurethattherearenoammablematerialsoropenames
nearby.
● Performatestruntoensurenormaloperation.Safetyguards,shields,barriers,covers,andprotective
devicesmustbeinplacewhilethecompressor/unitisoperating.Duringthetestrun,keepngersand
clothingawayfromanymovingparts.
● Cleanupthesitewhennished,rememberingtocheckthatnometalscrapsorbitsofwiringhave
beenleftinsidetheunitbeinginstalled.
● Duringtransportation,donotallowthebackrestoftheforkliftmakecontactwiththeunit,otherwise,
itmaycausedamagetotheheatexchangerandalsomaycauseinjurywhenstoppedorstarted
suddenly.
● Removegasinsidetheclosingpipewhenthebrazingworkisperformed.Ifthebrazingllermetalis
meltedwithremaininggasinside,thepipeswillbeblownoffanditmaycauseinjury.
● Besuretousenitrogengasforanairtighttest.Ifothergasessuchasoxygengas,acetylenegasor
uorocarbongasareaccidentallyused,itmaycauseexplosionorgasintoxication.
Afterinstallationworkforthesystemhasbeencompleted,explainthe“SafetyPrecautions,”theproperuse
andmaintenanceoftheunittothecustomeraccordingtotheinformationinallmanualsthatcamewiththe
system.AllmanualsandwarrantyinformationmustbegiventotheuserorleftneartheIndoorUnit.
