2.1 OutdoorUnits
2.1.1 Placementconsiderations
Placementofoutdoorunitsshouldtakeaccountofthefollowingconsiderations:
Airconditionersshouldnotbeexposedtodirectradiationfromahigh‐temperatureheatsource.
Airconditionersshouldnotbeinstalledinpositionswheredustordirtmayaffectheatexchangers.
Airconditionersshouldnotbeinstalledinlocationswhereexposuretooilortocorrosiveorharmfulgases,suchas
acidicoralkalinegases,mayoccur.
Airconditionersshouldnotbeinstalledinlocationswhereexposuretosalinitymayoccurunlesstheanti‐corrosion
treatmentforhigh‐salinityareascustomizationoptionhasbeenaddedandtheprecautionsdescribedinInstallation
Manual,10“InstallationinAreasofHighSalinity”aretaken.
Outdoorunitsshouldbeinstalledinwell‐drained,well‐ventilatedpositionsthatareascloseaspossibletotheindoor
units.

2.1.2 Spacing
Outdoorunitsmustbespacedsuchthatsufficientairmayflowthrougheachunit.Sufficientairflowacrossheat
exchangersisessentialforoutdoorunitstofunctionproperly.Figures3‐2.1to3‐2.3showspacingrequirementsinthree
differentscenarios.

IftheparticularcircumstancesofaninstallationrequireaunittobeplacedclosertoawallthanspecifiedinFigures3‐2.1
to3‐2.3,adischargeductshouldbeinstalled.RefertoInstallationManual,3“OutdoorUnitDuctingandShielding”.
Dependingontheheightofadjacentwallsrelativetotheheightoftheunits,ductingmayberequired.RefertoInstallation
Manual,3“OutdoorUnitDuctingandShielding”.

2.1.3 Masterandslaveunitpositioning
Insystemswithmultipleoutdoorunits,theunitsshouldbeplacedinorderfromlargestcapacityunittosmallestcapacity
unit.Thelargestcapacityunitmustbeplacedonthefirstbranch,andbesetasthemasterunit,whiletheothersshouldbe
setasslaveunits.RefertotheV5XServiceManual,ControlManualfordetailsofhowtosetunitsasmaster/slave.

TheexampleinFigure3‐2.4illustratestheplacingofunitsina48HPcombination:
Placethe22HPunitonthefirstbranchandsetitasthemasterunit.
Placethe16HPand10HPunitsonthenextbranchesandsetthemasslaveunits.


2.1.4 Basestructures
Outdoorunitbasestructuredesignshouldtakeaccountofthefollowingconsiderations:
Asolidbasepreventsexcessvibrationandnoise.Outdoorunitbasesshouldbeconstructedonsolidgroundoron
structuresofsufficientstrengthtosupporttheunits’weight.
Basesshouldbeatleast200mmhightoprovidesufficientaccessforinstallationofpiping.
Eithersteelorconcretebasesmaybesuitable.
AtypicalconcretebasedesignisshowninFigure3‐2.5.Atypicalconcretespecificationis1partcement,2partssand
and4partscrushedstonewithΦ10mmsteelreinforcingbar.Theedgesofthebaseshouldbechamfered.
Toensurethatallcontactpointsareequallysecure,basesshouldbecompletelylevel.Basedesignshouldensurethat
thepointsontheunits’basesdesignedforweight‐bearingsupportarefullysupported.Boltspacingsshouldbeasper
Figure3‐2.6andTable3‐2.1.
Adrainageditchshouldbeprovidedtoallowdrainageofcondensatethatmayformontheheatexchangerswhen
theunitsarerunninginheatingmode.Thedrainageshouldensurethatcondensateisdirectedawayfromroadways
andfootpaths,especiallyinlocationswheretheclimateissuchthatcondensatemayfreeze.

Whenunitsaredeliveredcheckwhetheranydamageoccurredduringshipment.Ifthereisdamagetothe
surfaceoroutsideofaunit,submitawrittenreporttotheshippingcompany.
Checkthatthemodel,specificationsandquantityoftheunitsdeliveredareasordered.
Checkthatallaccessoriesorderedhavebeenincluded.RetaintheOwner'sManualforfuturereference.

Donotremoveanypackagingbeforehoisting.Ifunitsarenotpackagedorifthepackagingisdamaged,use
suitableboardsorpackingmaterialtoprotecttheunits.
Hoistoneunitatatime,usingtworopestoensurestability.
Keepunitsuprightduringhoisting,ensuringthattheangletotheverticaldoesnotexceed30°.

2.2 IndoorUnits
2.2.1 Placementconsiderations
Placementofindoorunitsshouldtakeaccountofthefollowingconsiderations:
Sufficientspacefordrainpipingandforaccessduringservicingandmaintenanceshouldbeallowed.
Toensureagoodcooling/heatingeffect,short‐circuitventilation(whereoutletairreturnsquicklytoaunit’sairinlet)
shouldbeavoided.
Topreventexcessivenoiseorvibrationduringoperation,suspensionrodsorotherweight‐bearingfixingsshould
typicallybeabletobeartwicetheunit’sweight.

3 OutdoorUnitDuctingandShielding
3.1 DuctingRequirements
Dependingontheheightofadjacentwallsrelativetotheheightoftheunits,ductingmayberequiredtoensureproperair
discharge.InthesituationdepictedinFigure3‐3.1,theverticalsectionofductingshouldbeatleastH‐hhigh.

Figure3‐3.1:Top ofunitbelowtopofadjacentwall

3.2 DesignConsiderations
Outdoorunitductingdesignshouldtakeaccountofthefollowing:
Eachductshouldcontainnomorethanonebend.
Vibrationisolationshouldbeaddedtotheconnectionbetweentheunitandtheductingtoavoidvibration/noise.
Installinglouversisnotrecommendedasdoingsodecreasesairflow,impactinguponcooling/heatingperformance
andenergyefficiency.Iftheinstallationsituationnecessitateslouvers,theyshouldbeinstalledatananglenogreater
than15°tothehorizontal,tominimizetheimpactonairflow.

Beforeinstallinganindoorunit,checkthatthemodeltobeinstalledisasspecifiedintheconstructiondrawings
andconfirmthecorrectorientationoftheunit.
Ensurethatunitsareinstalledatthecorrectheight.
Toallowsmoothcondensatedrainageandtoensureunitstability(topreventexcessivenoiseorvibration),
ensurethatunitsareleveltowithin1°ofthehorizontal.Ifaunitisnotleveltowithin1°ofthehorizontal,water
leakageorabnormalvibration/noisemayoccur.
