Checktoensurethattheceilingissufficiently
strongtosustaintheSwitch Box.Iftheceiling
is weak,abnormalsoundandvibrationmay
occur.
Whentheelectronicexpansionvalveinthe
Switch Boxisactivated,achangeinthetypical
refrigerantflowsoundsmaybeheardor
perceivedfromtheSwitch Box.Takethe
following actiontominimizethesound.
(A) InstalltheSwitch Boxinsidetheceiling.As
for theceilingmaterial,selectamateriallike
a plasterboardatleast9mm(1inch),which
minimizesoperationsound.
(B) DonotinstalltheSwitch Boxinaplace
near bedroomsorhospitalrooms.
● Whentheoperationischangedtocooling/
heatingmode,achangeinthetypicalrefrigerant
flowsoundsmaybeheardorperceivedfromthe
Switch Box.
Therefore,installtheSwitch Boxintheceiling of
thecorridorsothattherefrigerantflowing sound
maynotbeheardintheroom.
● DonotinstalltheSwitch Boxinahotor humid
place,suchasakitchen,toprevent
condensationontheoutersurfaceofthe Switch
Box.
WheninstallingtheSwitch Boxinsuchplaces,
applyadditionalinsulation.
● Payattentiontothefollowingpointswhenthe
Switch Boxisinstalledinahospitalorother
facility wherethereareelectronicwavesfrom
medical equipment.
(A)
(B)
(C)
DonotinstalltheSwitch Boxwherethe
electromagneticwaveisdirectlyradiatedto
theelectricalboxorcommunicationcable.
● Ensuretheinstallationplaceisconvenient
fortherefrigerantpipingorelectricalwiring
connection.
● Donotdrill,ordrivescrewsintothecabinet. Use
onlymountingpointsprovided.
● IncasetheSwitch Boxisrequiredtomovefrom
the ceiling,prepareanotherserviceaccessdoor.
InstalltheSwitch Boxandcomponentsas
far aspracticableoratleast3m(10ft)
fromthe electromagneticwaveradiator.
Installanoisefilterwhenthepowersupply
emitsharmfulnoises.
