i.4.4.3.2Pipeconnectiontocoolingcoilsforchilledwater
Coilswith3rowsormoremustalwaysbeconnectedincounterflowtotheairflow.
NOTE:Theglycolmustbewithoutadditivesandautoglycolmustnotbeused.
Automaticbleedinghastobeinstalledatthehighest
pointofthe2pipes—supplyorreturnpipe.
i.4.4.3.3Valvemotorandvalveforheating
Thevalveandvalvemotorarenotinstalled.2‐wayor3‐wayvalveisavailable.
i.4.4.3.4Valvemotorandvalveforcooling
TThevalveandvalvemotorarenotinstalled.2‐wayor
3‐wayvalveisavailable.
i.4.5Drainingcondensatewater
Driptraysforcollectionofcondensatewaterareinstalledunderplateheatexchangerandcoolingcoil.Each
driptrayisprovidedwithadrainageoutlet.Awatertrapisalwaysnecessary.Toavoidfreezeupsandfrost
burstsofwatertrapandpipes,sufficientinsulationisrecommendedandinstallationofheating
between
theinsulationandwatertrap/pipescouldevenbenecessary(insulation,heatingandcontrollerforthe
heatingarenotdeliveredbySystemair).
Batteryseenfromabove.The
sensormeasuresthewater
temperatureofthewaterinside
oneofthesmallpipesforreturn
waterinthebattery.Thesensor
reducestheareainthispipeand
herebyalsotheflowofwarm
waterinthispipe.The
temperatureinthispipeis
reduced
morethanthe
temperatureinallotherpipes
bytheairflowthroughthe
battery.Becausethelowest
temperatureinthebattery
probablyismeasuredhere,this
systemcreatesearlyandsafe
warningoffrost.
Itisimportantthatthecapistightened
sufficienttokeepthesensorsystem
fullywatertight.
