ReceivingAndHandling
Trane HFCF Fan Coilunitsarepackagedin
individualcartons formaximumprotection
duringshipment, as wellasforeasy handling
and storage onthe jobsite.
Toprotect againstloss fromin-transit damage,
completethe followinguponreceiptoftheunits:
1. Inspect individualpieces of the shipment
beforeaccepting it.Checkforrattles, bent
cornersoncartons orothervisible
indicationsof shipping damage.
2.If acarton has apparent damage, openit
immediatelyandinspect the contents
beforeaccepting the unit.Donot refusethe
shipment.Makespecificnotations
concerning thedamageonthe freight bill.
Checkthe unit casing, fan rotation, coils,
drainpan, filtersand alloptions.
3.Inspect the unit forconcealeddamage
beforeit isstored and as soon as possible
afterdelivery.
4.Donot removedamagedmaterialfromthe
receivinglocationif possible.It isthe
receiver'sresponsibilitytoprovide
reasonableevidence that concealed
damagewas not incurred afterdelivery.
5.If concealed damageisdiscovered, stop
unpacking theshipment.Retainallinternal
packing and cartons. Takephotos of the
damaged materialif possible.
6.Notifythe carrier'sterminalof damage
immediatelybyphone and mailif any
damageisfound.Request animmediate
joint inspectionof the damagebythe
carrierandconsignee.
7.Notifythe Trane sales representativeof
the damage and arrange forrepair. Donot
repairthe unit yourself, however, until
damageisinspectedbythecarrier's
representative.
InstallationConsiderations
Forproperinstallation andoperation, check
eachof the followingbeforemountingthe
units:
1.Allowadequatespace fortheunit and free
airorservice clearancesreferenceFigure2.
SeeFigures4, 5and 6forgeneralunit
dimensions.Forservicingand routine
maintenance, provide accesstotheunit
through removablepanelsinthe ceiling.
2.Beforeinstalling any unit makesureproper
preparation hasbeenmadeat eachunit
location forpipingand electrical
connections.
3.Checkthat the supportingstructureis
strong enough tosupport unit weights, as
given on Figures4, 5and 6.
4.All unitsmust bemountedLEVELto
assureproperdrainageandoperation.
5. Ducting connected tounits(where
applicable)shouldnotexceedthe external
staticpressureratingof the unit.
6.Condensateprotection forthe chilled water
valves andpiping must beprovided by
installer. Adrainpanextension providedby
installershouldbelocatedunderthe valves
orelse the valves and piping shouldbe
thoroughlyinsulated.
7.Unitswithvalvepackage areequipped
withlongdrainpanwhichcancarrythe
condensationfromwatervalves.
Insulationofvalvepackageisnotrequired.
Mounting
The TranemodelHFCF unitsaredesigned to
be suspendedfromthe ceilingon 3/8-16
threadedrods furnished bythe installer. Holes
areprovidedat the topof the unit, seeFigures
4, 5and6forcutout dimensionsandlocations.
Toinstall the Trane modelHFCF, complete
the following:
6
1.Installthe suspension rods orother
suspensiondevices whichmustbe
providedbythe installer.
2.Put the upper W3/8nutsand W3/8lock
washersonsuspension rodstoprevent

3. Hoist theunit intoposition. SeeFigures4, 5
and 6forunitweights.
4.Put onthe lower W3/8lockwashersand
then W3/8nutstosecuretheunit, as
shownonFigure2 Typical Installation.
5.Leveltheunit casing toavoidpoor

StartUp/Operation
Preparation
Beforestartingthe unit, completethe above
mentioned INSTALLATIONCHECKLIST to
ensurethe properstart-up preparationis
completed.
Operation
Fancoil operation can becontrolled bya
simplemotorspeed switchorathermostat
unit.
Thewall-mountedthermostat unit usually
includesamotorspeedswitch, anon/off
switch and athermostat. The on/off switch
turns the unit on and off and themotor
speed switchcontrolsthe fanspeed. The
thermostat controlsthe watervalveand
usuallyhas adialtoselect an approximate
settingtemperature.
If the associated thermostat isnot usedfor
control, the installershouldchoose other
type of thermostatwhich complies withthe
safetycodes.
Thesimplemotorspeedswitch,labeledOff-
Hi-Med-Low, controlsthefan coilbyturning the
switchtodifferentspeedforadjustingtheair
flow.
Forthe unitwithelectricheateroption, a
high temperaturecutoutwithautomaticreset
(105 ℃ cutout, 85 ℃ autoreset)isprovided
tode-energize electricheat in
the event of an overheat condition.Inaddition
tothe automaticreset cutout, the unit also
equippedwithanotherhigh temperature
cutout withmanualreset (130 ℃ cutout).
These twotemp.cutoutsprovidedouble
protectionforelectricheatoperation.
Coil Venting
When waterisfirst introducedintoacoil, air
issometimestrapped inthecoiltubing. This
trappedairhasatendencytocollectat the
highest pointinthe coil. Therefore, amanual
airvent isinstalled at thehighest point of the
header. When thereappearstobe airtrapped
inthecoil, resultingin"bubbling"or
"clanking"noises withinthe unit, release air
fromthe manualairvent byrotatingthe knob.
Apairof plierscan beused if the knob istoo
tight toturnbyhand. Turnknob counter
clockwise 1-2turnsandallowairtoflowout
of theairventuntilasteadystreamof water
