Choosing an Installation Site

•Beforechoosingtheinstallationsite,obtainuserapproval.

1. Indoor unit

CAUTION

•Whenmovingtheunitduringorafterunpacking,makesuretoliftitbyholdingitsliftinglugs.Donotexertanypressureon

otherparts,especiallytherefrigerantpiping,drainpipingandangeparts.

Wearprotectivegear(suchasgloves)wheninstallingtheunit.

•Ifyouthinkthehumidityinsidetheceilingmightexceed86°F(30°C)andRH80%,reinforcetheinsulationontheunitbody.

Useglasswoolorpolyethylenefoamasinsulationsothatthethicknessismorethan0.4in(10mm)andtsinsidetheceiling

opening.

•Optimumairdistributionisensured.

•Theairpassageisnotblocked.

•Condensatecandrainproperly.

•Theceilingisstrongenoughtobeartheweightoftheindoorunit.

•Afalseceilingdoesnotseemtobeatanincline.

•Sufcientclearanceformaintenanceandservicingisensured.

•Pipingbetweentheindoorandoutdoorunitsiswithintheallowablelimits.

(Refertotheinstallationmanualfortheoutdoorunit.)

•Theindoorunit,outdoorunit,powersupplywiringandtransmissionwiringisat

least3.3ft(1m)awayfromtelevisionsandradios.Thispreventsimage

interferenceandnoiseinelectricalappliances.(Noisemaybegenerated

dependingontheconditionsunderwhichtheelectricwaveisgenerated,even

ifa3.3ft(1m)allowanceismaintained.)

■

Use suspension bolts to install the unit. Check whether or not the

ceiling is strong enough to support the weight of the unit. If there is

a risk that the ceiling is not strong enough, reinforce the ceiling

before installing the unit.

(Installationpitchismarkedonthecartonboxforinstallation.Refertoittocheck

forpointsrequiringreinforcing.)Selectthe*Hdimensionsuchthatadownward

slopeofatleast1/100isensuredasindicatedin“Drain Piping Work”.

•Theinstallationpitchislistedonthepackingmaterial,andshouldbechecked

whendecidingwhethertoreinforcethelocationornot.

Select the signal receiver mounting location according to the

following conditions:

•Installthesignalreceiver,whichhasabuilt-intemperaturesensor,nearthe

intakeventwherethereisconvectionofairanditcangetanaccuratereading

oftheroom’stemperature.Iftheintakeventisinanotherroomortheunit

cannotbeinstalledneartheintakeventforanyotherreason,installit5ft

(1.5m)abovetheooronawallwherethereisconvection.

•Inordertogetanaccuratereadingoftheroom’stemperature,installthesignal

receiverinalocationwhereitisnotexposeddirectlytocoldorhotairfromthe

airdischargegrilleortodirectsunlight.

•Sincethereceiverhasabuilt-inlightreceptortoreceivesignalsfromthe

wirelessremotecontroller,donotmountitinalocationwherethesignalmay

beblockedbyacurtain,etc.

Air outlet grille:

Wooden or plastic grille is recommended

because condensation may occur

depending on humidity conditions.

CAUTION

Ifthesignalreceiverisnotinstalledinalocationwherethereisconvectionofair,itmaybeunabletogetanaccuratereading

oftheroom’stemperature.
